Protection wisely: how to use the effective fungicide Quadris


Preparation of working solution

The suspension is diluted in a tank with a stirrer, the switch is set to the fine stream position. Strictly follow the sequence of actions, use only special containers (glass, non-food plastic).

Stages:

  • pour about ¼ of water into the tank;
  • pour in the fungicide in a thin stream;
  • stir gently (use a stirrer);
  • top up to full volume.

When preparing the composition, do not lower the hose with water into the solution, gradually raising it above the level as the tank is filled. To accurately measure the chemical, it is advisable to use a graduated beaker with a thin spout. Stir the solution for at least 3-8 minutes. During operation, the tank is constantly shaken so that the working composition is homogeneous and the suspension in it does not separate.

Used ampoules and vials are closed and disposed of. It is unacceptable to pour out the remaining solution, or throw away fungicide packages in cesspools or regular garbage.

Precautionary measures

Compliance with safety measures during processing is a guarantee that the dangerous substances of the drug will not have a negative effect on humans. So, the basic rules:

  • work in a professional set of protective clothing (with a rubberized layer);
  • use a respirator with a gas cartridge;
  • gloves are required.

If the solution gets on the skin, promptly wash it with plenty of water. If Quadris is accidentally ingested, then take 2-3 tablets of activated carbon with water. Then you need to urgently consult a doctor.

Do not work with the drug in the rain or wind. Visual inspection of treatment areas is required to avoid splashing the product onto healthy plantings.

Quadris is a fungicide from the list of innovative products that are effective, but require care, precision and care when used. Compliance with dosages and application rules makes it possible to get an excellent harvest with the least hassle.

The principle of action of the drug

Quadris is most effective during the early stages of development of fungal and some bacterial plant diseases. If the situation is severely advanced, then this fungicide should be used together with Ridomil Gold, Topaz, Skor and others.

The active ingredient Quadris destroys the genome of fungi and pathogenic bacteria, which guarantees a positive effect for farmers. The fungicide is able to penetrate not only into the leaves and stems of plants, thereby providing a therapeutic effect. It is also used to disinfect planting material, destroying pathogens inside the seeds.

Due to the fact that Quadris is a relatively safe drug, experts recommend its use in preventive measures. To do this, young plantings of tomatoes, onions, cabbage, cucumbers, hops, potatoes, as well as vineyards and lawns are treated with a fungicide solution, without waiting for the first signs of plant damage to appear.

Fungicide Fundazol: description, instructions for use

Advantages and disadvantages

Quadris is an innovative product that has its own advantages:

clear focus against sporulation of pathogens; effectiveness against dangerous microorganisms and neutrality towards almost all beneficial fungi (this is very important for novice gardeners, who cannot always immediately recognize an infection by its symptoms); safety for soil microflora; limited translaminar action (accumulation occurs in leaf blades, there is no penetration into shoots or fruits); Fruit harvesting is allowed 3-4 days after treatments; protective properties do not depend on weather (valid in the range from +4ºC to +30ºC); compatible with a large number of fungicides (Topaz, Dzherelo, Defender); combined use with biological products is allowed; in addition to protecting and treating plants, Quadris helps increase immunity and resistance to adverse weather factors; It is allowed to treat the seeds before sowing (according to the instructions). Instructions for fungicide:

Instructions for fungicide:

  • belongs to toxic agents (for humans - hazard class II, for inhabitants of water bodies - I). This requires compliance with safety measures during processing, taking into account the location of areas and plantings in relation to ponds, rivers, streams;
  • Causes pathogens to become addictive, which reduces their effectiveness over time. It is allowed to use Quadris for no more than 2-3 years in one area, and it is necessary to alternate treatments with other fungicides;
  • due to the penetration of the active substance into the flowers of plants, it is prohibited to use Quadris during flowering (may cause poisoning of bees);
  • It is phytotoxic for most crops, so it is necessary to strictly adhere to the dosage of the product, as well as the processing rules.
  • to completely destroy fungi, it is necessary to use Quadris with preparations of a different chemical base;
  • high price.

For each crop, the manufacturer has developed specific dosages and consumption, so when processing, it is necessary to strictly observe the proportions and act strictly according to the instructions.

Toxicity and storage

The drug is dangerous to humans and poisonous to the inhabitants of ponds, rivers, and lakes. During work, the active substance penetrates through the mucous membranes, skin, and respiratory organs of a person, therefore, when working, they use special clothing and monitor the condition.

Phytotoxicity of Quadris manifests itself in blocking flowering and fruit formation in plants. In case of an overdose, productivity indicators sharply decrease or the plant does not bear fruit at all.

Thresholds of toxicity indicators are different for crops: Quadris fungicide is less dangerous for lawn grasses, onions (grown for turnips), and tomatoes. The threshold for fruit trees tends to zero, so cultivation of the vegetable garden next to garden plantings must be carried out very carefully.

When working on large areas, separate sprayers for the garden and vegetable garden are prepared in advance. After treatment, the residues are disposed of and the containers are thoroughly washed.

Analogues of the drug

Like many fungicides, Quadris has analogues whose effect on pathogens is identical. The list includes:

  • Folicur - produced by Bayer, used mainly on grain crops and rapeseed;
  • Strobi - produced by BASF, active ingredient - kresoxim-methyl (from strobilurides);
  • Consento is a fungicide from the group of systemic drugs, produced by Bayer. It is used against late blight and alternaria on tomatoes, potatoes, and against downy mildew on onions;
  • Prosaro is a systemic fungicide from Bayer. It is highly effective when used on grain crops, rapeseed, corn, peas against septoria and fusarium.

If necessary, these drugs can be used instead of Quadris, taking into account the instructions.

Quadris analogs

There are drugs on sale that are similar in composition and principle of action to Quadris:

Capital. Fungicide used to protect cereals, corn, soybeans, fodder beets, peas and sunflowers. Active ingredients: azoxystrobin, epoxiconazole, cyproconazole. It has a translaminar ability to penetrate into the leaf blade. But this chemical is more toxic. Has toxicity class II. The fungicide is produced by UKRAVIT.

Azoxin. Azoxystrobin was used as the active ingredient of the suspension. Produced by Agrochemical Technologies. Used to protect against fungal diseases of grains, vegetables and vineyards. Does not have a resistant effect.

Using the modern drug Quadris, you can protect garden and vegetable plants from fungal diseases. This will allow you to get a high-quality and large harvest.

Safety regulations

When manufacturing and using Quadris, it is necessary to use protective equipment, despite its low toxicity.

  1. May have a toxic effect on the inhabitants of water bodies. Therefore, use near open ponds and swimming pools is prohibited.
  2. Do not store the drug or solution containers near food and household items.
  3. You should carefully select the weather for carrying out protective measures. Do not spray plants before rain or in hot, windy weather.

In case of contact with exposed parts of the body, wash the skin with plenty of water using a soap solution.

In case of accidental exposure to the respiratory system, immediately take absorbent agents and contact a medical facility. It is advisable to have the instructions for the drug with you.

Store the drug with intact packaging in a dark place at an air temperature of -5 to +35 degrees. The shelf life is 36 months from the date of manufacture. When spraying, it is necessary to use a freshly prepared active solution according to the instructions for its use; it is not recommended to store or use it for more than 24 hours.

The fungicide is safe for humans, bees and birds, but is dangerous for fish, so treatment should not be carried out near water bodies. Also, if it comes into contact with human skin, it can cause dizziness and vomiting, so during treatment you should use a change of clothes, gloves and a hat in order to protect yourself from negative consequences. Quadris also has a characteristic odor, so spraying should be done in the morning or evening to avoid increased evaporation.

It is important to know that you should not treat apple trees with quadris, since some varieties are very susceptible to its action, which can result in foliage burns. The drug can be used in combination with other treatments; this quality helps to significantly reduce the number of regular treatments

In case of any doubt, it is necessary to conduct a trial test before complex treatment, which will help determine whether the drugs are compatible or not

The drug can be used in combination with other treatments; this quality helps to significantly reduce the number of regular treatments. If any doubt arises, it is necessary to conduct a trial test before complex treatment, which will help determine whether the drugs are compatible or not.

Tips and tricks

Tips and recommendations for using the fungicide "Quadris":

  • The solution must be prepared immediately before use; it can be stored for 6 hours.
  • After spraying, eating grapes is not allowed for 4 days.
  • It is not recommended to use the drug against fungal diseases in conjunction with herbicides; Quadris is compatible with all other types of chemicals. If it is necessary to use two types of these fertilizers, then the break between treatments should be at least a week.
  • You cannot use the drug in the same place for more than 2 years in a row. Fungi develop immunity to this chemical.
  • The drug can enter the body through hair, so it is also worth protecting it during work.

Instructions for use

To work with Quadris fungicide, a sprayer with an agitator is required. The solution is prepared in a laboratory or other non-residential premises. 1 liter of water is poured into the tank, to which the suspension is added. Then the solution is adjusted to the required volume depending on the type of crop to be treated. The mixer is turned on for 5-10 minutes.

Spraying requires a sprayer that produces a fine stream. After opening the containers, the suspension must be used within 24 hours. The prepared solution cannot be stored. Its volume must be accurately calculated before starting work.

Initially, the fungicide Quadris was developed for the treatment of sports lawns. The use of the drug eliminates fusarium and various spots. As a result, the resistance of grasses to trampling increases.

For processing, prepare a working solution containing 120 ml of the substance per 10 liters of water. If the drug is used in the first year, 0.2 liters of solution per 10 square meters is sufficient. m. lawn. In the second year, use 2 times more solution.

The first treatment is carried out when the first leaves begin to unfold on the seedlings. The procedure is repeated every 20 days. Up to 4 treatments are allowed per season.

The most common diseases of grapes are oidium and mildew. To combat them, dilute 60 ml of suspension per 10 liters of water. For 1 sq. m of planting, 1 liter of the resulting solution is sufficient.

During the season, 2 grape treatments are performed. For preventive purposes, the vine is sprayed before flowering and after harvesting. If the berries begin to stain, it is better to avoid using the fungicide. A gap of 1-2 weeks is maintained between treatments.

Tomatoes and peppers

Tomatoes and peppers are susceptible to late blight, Alternaria blight and powdery mildew. For open ground, dilute 40 ml of fungicide per 10 liters of water. Consumption rate per 10 sq. m is 6 l.

According to the instructions for use of Quadris, to treat greenhouse crops, take 80 ml of suspension per 10-liter bucket of water. Solution consumption per 10 sq. m. should not exceed 1 liter.

Plants are treated no more than 2 times per season:

  • before flowering begins;
  • when the first fruits appear.

When growing tomatoes and peppers in open ground, wait 2 weeks between procedures. Greenhouse plants are treated no more than once every 10 days.

Fungicide Quadris protects cucumbers from powdery mildew and peronospora. Add 40 g of suspension to 10 liters of water. Consumption of the resulting solution per 10 sq. m of planting in open ground is 8 liters. In greenhouses, 1.5 liters is sufficient.

During the season, cucumbers are processed twice: before and after flowering. A gap of 2 weeks is maintained between treatments.

Treatment with Quadris protects potatoes from rhizoctonia and silver scab. According to the instructions for using the fungicide Quadris, add 0.3 liters of suspension to a 10-liter bucket of water.

The volume of the solution depends on the area of ​​potato planting. For every 10 sq. m. requires 0.8 liters of ready-made solution. If the treatment was already carried out last year, then the specified rate may be increased to 2 liters.

The soil is irrigated before tubers are planted. The protective effect of the drug lasts for 2 months.

When growing onions for turnips, the use of the fungicide Quadris protects the crop from downy mildew and fusarium wilt. For 10 liters of water, use 80 ml of suspension.

Spraying is carried out no more than 3 times during the entire growing season. For 10 sq. m. use no more than 0.2 liters of solution. Leave 2 weeks between treatments.

Treating strawberries with a solution of the fungicide Quadris provides protection against gray rot, spotting and other fungal infections.

Add 40 ml of the drug to a 10-liter bucket of water. Treatment is carried out before flowering begins, repeated spraying is carried out after harvesting.

The drug Quadris: reviews of use in the garden

Maria, 44 years old, Sverdlovsk region: Unfortunately, our cellar is flooded with meltwater in the spring. As a result, even after drying, mold appears on wooden structures, and potatoes stored for storage quickly begin to rot. I was advised to treat our vegetable storage area with Quadris during the summer. I carried out a couple of treatments: one in the summer, the second a few days before storing the crop. As a result, the potatoes were well stored all winter, and even in the spring there were practically no rotten tubers.

Valentina, 50 years old, Ryazan: I usually try not to treat tomatoes with chemicals during the growth and ripening process. But after treating the ripe fruits with folk remedies, up to half of the harvest was lost. Last season I tried to treat tomato bushes with Quadris - as a result, all the tomatoes remained healthy. I recommend to all.

Dmitry, 45 years old, Volgograd region: For many years I have been growing grapes in my garden plot for sale and for personal purposes. There were seasons when my grape plantation was affected by mildew. And only after I began to use Quadris for processing grapes, this disease receded. Now, for preventive purposes, in spring and autumn I always spray the grapevines with this drug.

This systemic contact fungicide is a new generation drug, it is very effective

. However, it must be remembered that an overdose of Quadris has a negative effect on garden and vegetable crops. And its lack reduces the effectiveness of the product, so it is very important to use Quadris according to the instructions for use.

Pros and cons of the substance

An effective mechanism of action should not tempt a gardener or gardener without a full study of the positive and negative aspects of use. The Quadris substance does not contain chemical pesticides. But there are plenty of disadvantages to refuse spraying on your site.

There are, of course, more advantages to using it. The provided crop protection is short-term (up to 21 days). After the fungicide has eliminated pathogens, it disintegrates, leaving no trace. The breakdown of the active substance into:

  • nitrogen;
  • oxygen;
  • hydrogen and carbon are harmless.

Blocking sporulation completely eliminates the problem and prevents the resumption of fungal infection for another 2 seasons. Additional advantages are also called:

  1. Photosynthesis accelerates and intensifies. This makes it possible to withstand temperature changes and bad weather conditions. Application of Quadris is allowed at temperatures from +4 to +35 degrees.
  2. You can always combine it with other fertilizers. Drugs that do not contain strobilurins. Quadris does not interfere with all methods of increasing yield. Can be combined and added with humus, compost, humate.
  3. It has an accumulating effect, but does not penetrate into the fruit. Protective qualities are retained during winter storage. No additional processing is required for preservation.
  4. Use before sowing is allowed to treat soil microflora and microfauna. This makes it possible to prevent diseases and avoid the use of serious chemicals.
  5. Broad spectrum of action: kills all known pathogenic fungal spores. This quality allows beginning gardeners and farmers to use the product.

If we talk about negative aspects, then the first thing you need to know is that Quadris must be diluted strictly according to the instructions. An overdose can kill the plant rather than cure it. Since the substance is hazard class 2, it means that processing must take place in a protective suit. Pets should be kept away from the application area.

One of the disadvantages of Quadris is that the substance is not used annually. And also, you cannot spray during budding and flowering. If there are bodies of water near the land plot, there is a risk of poisoning fish and river inhabitants.

Description of the drug and features

The composition of any fungicide is based on an active substance, due to which the effect on microorganisms occurs. For Quadris, this is a representative of the strobilurin group - azoxystrobin. The mechanism of action is simple: the component forms a thin film coating, thereby blocking the supply of oxygen to fungal spores and causing their death.

The effect occurs approximately an hour after treatment, the protection period is 14-21 days. After the reaction, the active substance breaks down into safe components that do not pose any threat to the human body and plants.

Quadris does not contain ions:

  • phosphorus;
  • sulfur;
  • metals

Therefore, after using the drug, its components do not accumulate in plant fruits. Azoxystrobin partially penetrates into the tissues of leaves and shoots, but most of it remains on the surface in the form of a film. Therefore, the fungicide is classified as a means of both contact and systemic action.

Security measures

The drug Ridomil Gold is toxic, therefore, when using the drug Ridomil, personal protective measures must be observed. Basic Rules:

  • work only in special clothing, goggles and a respirator;
  • use of special containers for preparing solutions;
  • compliance with dosages;
  • storage of the drug in separate places, closed from accidental access;
  • Dispose of opened empty packaging immediately.

If the product accidentally gets on the skin, wash it off with water. If the drug is inhaled or swallowed, drink plenty of water and call a doctor promptly.

After processing, the workwear is sent for washing and a shower is taken.

You should not be skeptical about safety recommendations, as this allows you to minimize the toxic effects of Ridomil Gold and avoid poisoning.

Toxicity and storage of the product

The drug is highly toxic to humans and warm-blooded animals, as well as to the inhabitants of water bodies. When working with this fungicide, its vapors can penetrate through the mucous membranes and skin, and into the respiratory system. Therefore, from the moment you prepare the working fluid until the end of the work, you should wear protective clothing, use a respirator and rubber gloves.

The drug is also phytotoxic - it can block the development of buds and ovaries. If the dosage is exceeded, the plant productivity drops sharply, or fruiting stops altogether.

The toxicity of Quadris for different crops can vary greatly: this fungicide is least dangerous for grass grown on lawns, onions grown for turnips, and tomatoes. But for fruit trees, Quadris is highly toxic, so when spraying garden beds located next to the garden, you need to be extremely careful so that the working liquid does not get on the trees.

For work in the garden and vegetable garden, separate spray bottles should be used. After treatment, the remaining working solution is disposed of, and the containers are thoroughly washed under running water.

"Ridomil Gold" for processing grapes

Ridomil Gold: beneficial properties

  • Mancozeb (64% concentration).
  • Metalaxyl (8%).

The substances penetrate inside the plant and protect all its parts from roots to berries. They settle on the surface of the green mass. Strengthens the vines' immunity to fungal diseases. The drug demonstrates high therapeutic and prophylactic properties against mildew. It has no effect on oidium pathogens.

Advantages and disadvantages of Ridomil Gold

Reading reviews from agronomists about the drug Ridomil Gold, novice gardeners will certainly pay attention to the possibility of using it for therapeutic and prophylactic purposes in the early stages of grape infection with a mycotic infection. Other advantages of the drug are:

Other advantages of the drug are:

  • No phytotoxicity;
  • Bilateral protection of bushes from infection;
  • Possibility of protecting the root system;
  • Speed ​​of penetration into the vine;
  • Ease of use - thanks to PEPIT technology, the granules dissolve in water in just 1 minute. The risk of accidental inhalation of the fungicide is minimal, since the granules are characterized by high density and large size;
  • Ease of storage - the substance does not lose its beneficial properties at temperatures from -10 to +35°C;
  • The ability to protect onions, potatoes and other vegetables from diseases;
  • Availability of analogues - Tragon, Tyler, Junker, Healer.

The disadvantages of the product include high toxicity to humans, animals and fish, wasteful consumption and environmental harm. But if you use the fungicide wisely, the gardener will avoid trouble.

How to use Ridomil Gold for grapes

Before spraying the plantation, check the sprayer - it should not contain residues of other drugs. Ridomil Gold solution is made for grapes according to the instructions for use, focusing on the ratio of 25 g of the substance per 10 liters of water. If there are few plants, the dose is reduced to 10 g of the drug and 4 liters of liquid.

The grapes should be sprayed with a fungicidal agent immediately after preparation. The work is carried out in the morning in dry weather. The sprayer is held towards the wind, avoiding inhalation of the chemical. Mature clusters are cut 2 to 3 weeks after the garden was sprayed for the last time.

How often can you spray grapes against fungus with Ridomil Gold:

  1. The first preventive measure is carried out in the spring at the 4-leaf stage.
  2. The second and subsequent treatments are performed at intervals of 2 weeks.
  3. The final treatment is carried out 14 days after the bushes have faded.

The drug consumption is 100 – 150 ml/sq.m. They don’t make it with a reserve. You should always prepare a fresh solution. They spray the grapes wearing a special suit, gloves and a mask.

If it suddenly rains the next day, the grapes do not need to be sprayed again. Metaloxyl on the surface of the leaves is instantly converted into a protective film that is not afraid of moisture. Mancozeb appears inside the bush structure half an hour after the procedure.

The second class of toxicity of the fungicidal drug warns of the danger of granules for humans and fish. There are no consequences for birds and bees. To avoid environmental pollution, it is prohibited to spray the solution near open reservoirs and fish breeding farms.

Storage conditions

Powder and granules of Ridomil Gold are not afraid of low temperatures. But you can’t store packages in the yard; it’s better to keep them indoors. Moisture should not penetrate into the printed bag, otherwise the substance will form lumps and lose some of its beneficial properties.

The drug is not flammable. Therefore, you don’t have to worry about fire safety. When properly stored, the powder and granules retain their fungicidal properties for 3 years from the date of release.

The product is sold on the official website and in specialized stores. The price of 1 kg of powder is 10 – 15 dollars. You can buy the drug wholesale and retail. The manufacturer positions its product as a preventive measure, but many summer residents have already become convinced that Ridomil Gold is the best cure for fungal diseases for grapes.

Processing times

The drug is suitable for prophylactic use and in the early stages of the disease. Because, first of all, it stops the growth of fungi and spore formation, and does not lead to complete destruction. The validity period of “Quadris” on grapes is about three weeks. The waiting time for the drug to take effect is 2-3 days.

The right time to process grapes is:

  • before flowering;
  • after flowering;
  • time of immature ovaries;
  • a week before harvest.

Processing the bushes shortly before harvesting increases its shelf life. Repeated treatment can be carried out no earlier than after 3 weeks. In one season, it is advisable not to carry out more than two treatments with Quadris, but to alternate with other fungicides.

What fungicides are used for grapes

All gardeners who grow grapes on their plots know that diseases and pests provoke a decrease in crop yields. When fungal pathologies spread, the indicators drop by half, and with massive damage, almost the entire harvest is lost

That is why it is important to know which preparations for grapes are best used, and according to what scheme. With periodic processing, the risk of mass losses is minimal

System

The principle of action of systemic fungicides for diseased grapes is their ability to penetrate deep into plant tissue. Due to such activity, the development and growth of pathogenic microflora is suppressed. The products are used for the prevention and treatment of infected bushes. For mild infections, a single treatment is sufficient.

Compared to contact agents, systemic agents have distinct advantages:

quickly penetrate tissues and act on them; no need to pay attention to weather conditions, the compositions are not washed off by rain; have a therapeutic effect, it manifests itself immediately after using the product; effective against viral diseases of grapes; the frequency of treatment is reduced to 3 times per season. The list of the best funds in this group can be presented as follows:

The list of the best funds in this group can be presented as follows:

  • "Quadris";
  • "Folpan";
  • "Skor";
  • "Strobe";
  • "Topaz";
  • "Falcon".

Basic recommendations for their use:

  • It is recommended to spray in the morning or evening;
  • the air temperature outside should be from 5 to 30 degrees Celsius;
  • To prevent the spread of the drug to neighboring crops, treatment should be carried out in calm weather.

Compliance with these rules ensures that the processing is effective.

Contact

To achieve a pronounced and lasting therapeutic and prophylactic effect, contact-acting preparations must be carefully applied to the entire above-ground part of the plant. In this case, you should cover the vine and leaf plates. Rain after treatment reduces the effectiveness or completely eliminates all efforts. The procedure will have to be repeated.

List of the best drugs in this group:

  • "Shavit";
  • "Fundazol";
  • "Tiovit jet";
  • "Cuprozan".

Gardeners try to use such products as little as possible. This attitude towards compositions is explained by the high frequency of procedures - up to 7-8 times. One treatment each in spring, summer and autumn will not be enough. If you miss the spraying period recommended by the instructions, the entire effect will disappear. Next, you will have to use complex or systemic drugs.

Complex

The main advantage of drugs in this group is that they combine the action of contact and systemic agents, but they make their own adjustments to the plan of use

Such substances must be handled with care. They are harmful and toxic to humans, but provide indispensable assistance in case of massive fungal infection of grapes

The list of effective means of this group includes the following names:

  • "Mikal";
  • "Shavit";
  • "Flint";
  • "Convertible Top".

In case of threatening damage to the grapevine, the use of complex preparations is the best solution. You should not waste time and money on treating serious problems with systemic and contact substances. Most likely, the effect will not please you.

Purpose

The drug "Quadris" has a wide range of effects. It is used to treat most grape diseases.

Mildew

Mildew is downy mildew. Characteristic signs of this disease are the appearance of a white coating on the foliage and fruits, a decrease in yield, falling inflorescences, and yellow spots on the front side of the leaf.

Mildew is considered one of the most common and dangerous diseases of grape bushes. The grapes do not have time to develop; they gradually acquire a purple tint, and then shrivel and fall off. The cause of downy mildew is increased humidity and watering with cold water.

Late blight

Another common grape disease is late blight. The danger of the disease is that it can be transmitted from plant to plant, and if measures are not taken in a timely manner, most of the crops on the site will soon become diseased. Late blight usually appears in the second half of summer. The development is caused by excessive humidity and low temperature.

The first signs of the disease are dark spots surrounded by a white border that appear on the leaves. The affected parts of the grapes die off after some time. The grapes grow small, lose their taste and become unsuitable for food.

Oidium

Oidium is true powdery mildew. As the disease progresses, the fungi also attack the berries. The grapes, not having time to ripen, begin to crack. Just like the leaves, they are covered with a white coating. Another sign is the appearance of the smell of rotten fish.

The main danger of oidium is that the disease develops quickly and can kill the entire vineyard in just a few weeks.

Gray rot

Inflorescences with gray rot fade and fall off. If the weather is humid, they become covered with a gray coating. The berries become brown and covered with fluff. Then they rot and fall off. The fungus rarely affects leaves, only if it is humid outside. Then dark spots appear on them. Gray rot develops mainly in September. The occurrence of the disease can be prevented by regular pruning and preventative treatment of bushes.

Downy mildew

Downy mildew is one of the names of downy mildew.

Alternaria blight

Alternaria causes necrosis of the above-ground parts of the grapevine (leaves, shoots, petioles). Weakened bushes are primarily susceptible to this disease. The cause of Alternaria blight is hot, humid weather.

The foliage begins to become covered with light spots. In appearance, they can easily be confused with signs of powdery mildew. As the disease progresses, they become dark brown in color. At the last stage, the foliage turns black and dries out. Treatment should begin as soon as the first symptoms appear.

If delayed, the fungus will not only kill the vineyard, but will also spread to nearby crops.

Powdery mildew

The first signs of the disease appear first on young leaves and shoots. The leaves take on a whitish tint, as if they had been sprinkled with flour or dust. If you rub the leaf with your finger, the coating will be erased.

Black spot

Black spotting is also called escoriosis, dry-spot and fomospis. The disease affects all parts of the grapes, from stems to foliage. Black spots initially appear on the foliage, which gradually increase in size. At the edges they are light and slightly compacted. The spots are usually located next to the veins. Because of this, the leaves become curly. As a result, the leaf turns yellow and falls off.

Spots appear on the shoots towards the end of flowering. Diseased shoots break easily. If the disease is neglected, the vine will gradually become covered with black scabs. When the fungus penetrates deep into the wood, most of the bush dies and all that remains is to dig it out.

Infectious drying out

Infectious drying of bushes can occur due to a fungal infection - black cancer. Or because of eutyposis. Symptoms of infectious drying can vary depending on climatic conditions and the causative agent of the disease.

The disease is divided into two stages. The first is the accumulation of microorganisms in wood, which lasts 2-3 years. During this time, the disease may not manifest itself in any way. The second stage is the drying out of the bushes. If you cut the stem, there will be dead wood inside it. Damaged parts of the vine must be destroyed. To prevent the development of infectious drying, preventive treatments are carried out in the spring and during the growing season.

Current questions about the use of Quadris

There is not a single approved drug based on azoxystrobin for private farms. From the group of strobilurins, an ordinary summer resident can legally purchase only fungicides with famoxadone - “Profit Gold” → how to use reviews, “Famox” and “Thanos” → how to use reviews. Until recently, “Strobe” based on kresoxim-methyl could have been added to this list, but its registration period has expired. Perhaps after some time it will appear on the market again.

In addition to strobilurins, there are many safer fungicides based on natural compounds. For example, “Alirin-B” → how to use a fungicide, “Pseudobacterin”, “Planriz” → instructions for using the drug. Mycoplant is well suited for suppressing pathogen spores in the soil.

Question No. 2. How to breed “Quadris” for onions and potatoes? (click to expand)

Onions are treated with Quadris against peronosporosis twice, with an interval of 10 days. The concentration is quite high - 800 ml of emulsion per 200 liters of water. The working solution is consumed per 1 ha. Onions that are harvested are not treated with this fungicide.

Potatoes are sprayed with Quadris not on the leaves, but on the seed tubers before planting. The solution is prepared even stronger than for onions - from 3 liters of emulsion and 200 liters of water.

Feedback from farmers on the effectiveness of the fungicide "Quadris"

“I have been using Quadris in my vineyard against mildew for 6 years now. In my climate

Small packaging of Quadris is done illegally. You need to beware of fakes.

conditions the drug is effective. I once saved my grapes with it when I discovered anthracnose dots on some berries, although anthracnose was not indicated in the instructions for the drug. Overall, I'm happy with Quadris. But there is a nuance. I noticed that it is highly toxic to apple trees. If you pour fungicides for apple trees into sprayers without rinsing them after leaving the vineyard, there will be traces of burns” (Vitaly, Krasnodar region).

Indeed, there is evidence that this fungicide is phytotoxic for a number of crops. That is why when using it you cannot deviate from the regulations.

As the above review shows, a negative effect can be observed even from traces of Quadris remaining in the equipment. To rinse sprayers it is necessary to use a large amount of clean water. After cleaning the equipment, it should not be poured onto the ground - only into a specially equipped cemented pit for collecting wash water.

Pathogenic microorganisms sensitive to the drug

Azoxystrobin works against a wide range of fungal infections. Therefore, Quadris is able to cope with a long list of plant diseases:

  • mildew;
  • oidium;
  • peronosporosis;
  • powdery mildew of cucumbers and tomatoes;

ALL diseases that Quadris helps with (click to expand)

  • late blight;
  • Alternaria blight;
  • rhizoctoniasis;
  • silver scab;
  • fusarium;
  • Helminosporium spots.

Treatment of crops is carried out only by spraying on the leaf. When working, it is extremely important to use waterproof professional protection kits - overalls, boots, gloves, respirator and goggles.

How to use

Spraying with Quadris is carried out in the morning or evening, when the sun's rays are no longer so scorching. The solution consumption should be such that it covers the entire vineyard. The solution should not be allowed to drain and fall on the ground. To prevent this, you should use a spray bottle with the finest atomizer possible.

The maximum number of treatments allowed per season is 3, if the solution is used for treatment. Preventive spraying is carried out twice a season with breaks of 10-14 days.

Manual packaging of Quadris: is it worth buying?

When talking about Quadris, we have to take into account the fact that the factory packaging of this drug has a large volume - 1 liter. Its cost averages about 4,800 rubles, and this makes the fungicide inaccessible to the average summer resident.

This situation has caused the appearance of a mass of small packers on the horticultural market, who manually pour the concentrate into small containers and sell it at a price of approximately 100 rubles per 10 ml. On the one hand, this allows any gardener to purchase Quadris at an affordable price. On the other hand, it raises a number of questions regarding compliance with technical regulations for working with pesticides.

Any fungicide, even from the group of conditionally safe ones, interferes with the ecology of the site. In addition, there is no guarantee that illegal packers comply with the rules for storing opened goods.

Not only grapes can be subjected to additional treatments with Quadris. If, despite prevention, tomatoes or cucumbers become sick, this drug will quickly eliminate the infection.

factory drug or not bottled into small bottles and ampoules, it is an outright counterfeit. Therefore, before purchasing “Quadris” marked “manual packaging,” you need to think carefully.

Precautionary measures

The drug is toxic only to fungal spores; it does not pose a danger to humans. But it is still advisable to take precautions during processing. If a small amount of the chemical enters the body, the following symptoms may occur:

  • dizziness;
  • nausea;
  • vomit.

It is better to immediately call an ambulance, but if this is not possible, then you need to rinse your stomach. To prevent such situations from arising, before spraying you need to wear a protective suit and mask to avoid inhaling the solution. Animals should also not be allowed to come into contact with the drug.

Operating principle and main active component

The pesticide has gained high popularity due to its simple but effective principle of action on the pathogen.

The main component of the product is the substance azoxystrobin at a concentration of 250 g/l (25%). After contact with the surface of the fungus, azoxystrobin creates a film that blocks access to oxygen for harmful microorganisms. This, accordingly, causes inhibition in development and further death of the pathogen.

A distinctive characteristic of the drug is its immediate effectiveness. After the fungicide Quadris has reached the surface of the pathogen, its death occurs within an hour after treatment. However, despite such fast work, it is still recommended to use the product in the early morning or evening, when there is no sun outside. It can negatively affect the effectiveness of spraying, since the chemical has high evaporation rates.

Unlike many other fungicides (the same Acrobat or Strobi), Quadris is not resistant to rain. Crops need to be sprayed when there is no precipitation expected. Otherwise, the procedure will have to be repeated a second time.

Note that experienced gardeners rarely use this fungicide alone. Typically, it is used with systemic medications. For example, Quadris goes well with pesticides such as Topaz and Aktara. But combining it with herbicides is contraindicated.
