Instructions for use of the fungicide Previkur Energy, its compatibility with other drugs and analogues

Composition, active substance

The main active ingredients of Previkur Energy are aluminum phosphate (310 g/l) and propamocarb hydrochloride (530 g/l). The combination of these two ingredients is very effective - together they suppress most pathogens living in the soil.

This fungicide has a neutral reaction, and propamocarb and fosetil can stimulate crop growth.

It is manufactured in Germany and is a system product. Previkur Energy is diluted in water and watered or sprayed on the soil.

The fungicide is a water-soluble concentrate available for sale in 60 ml bottles or 1 liter canisters.

When diluting Previkur Energy, strictly follow the instructions for use.

Release form

Previkur Energy" is a pink, water-soluble concentrate. The active ingredients are propamocarb hydrochloride in combination with aluminum phosphate. This allows the drug to exhibit fungicidal and fungistatic activity against a wide range of pathogens.

The fungicide is produced by the German company Bayer, which has a strong position as a reliable manufacturer of plant protection products.

Available in 5 ml, 15 ml, 50 ml and 100 ml packs for home use and in 500 ml and 1500 ml packs for professional use over large areas.

Description and release form

The agricultural market offers enough substances that can eliminate the threat of infection and remove pathogenic microbes. But the fungicide

Previkur differs from the mass of the offered product in two ways:

• has a pronounced protective effect;
• has biostimulating properties.

The protection product is an innovative technology created by the German company Bayer Garden. The Germans have always been famous for their precision, determination and desire to be the best. Therefore, you can trust the effectiveness of Previkur. The description of the drug should begin with the composition, in which the main components are:

• aluminum fosetyl;
• propamocarb hydrochloride.

The peculiarity of the drug is that it is a concentrated substance. But hydrogen indicators are neutral. Two main ingredients give a special chemical reaction, which helps to suppress pathogens.

An additional effect of this formula was the stimulation of growth of both young plants (shoots) and adults (tops). Its versatility also lies in the fact that Previkur kills not only fungal spores, but also other diseases that occur on soil and garden crops.

When using a fungicide, you don’t have to worry about infection for a long time, since the concentrate has a long-lasting effect.

The Previcure formula allows you to use it in the following ways:

• spraying;
• drip irrigation;
• root application (watering).

From what diseases

The fungicide protects plants for 7-14 days without causing resistance. To achieve maximum effect, you must strictly follow the instructions for use and not exceed the permissible dose of the drug.

Indications for use:

1. Root and basal putrefactive lesions (pathogens Pythium spp., Phytophthora sp.).
2. Bacteria of the genus Pseudomonas.
3. Fusarium (pathogen: Fusarium sp.).
4. Peronosporosis (another name is downy mildew, caused by Pseudoperonospora spars and Bremia lactucae).
5. Late blight (pathogen Phytophthora infestans).

After the first application, most pathogenic microorganisms die (more than 90%). Repeated use completely destroys pathogens and has a beneficial effect on plants: stimulates the growth and development of roots, enhances flowering.

In addition, the drug is actively used for preventive purposes. Used to prepare soil for growing plants in greenhouse conditions.

It is also used for better rooting of seedlings. To do this, the drug is poured onto the soil with the seeds, and then re-applied at the seedling growth stage.

Norms for use of the drug

Consumption rates for various crop diseases are given in the table below.

Previkur Energy against cladosporiosis (powdery mildew)

1. Working solution for irrigation - 3 ml per 2 liters of water. Treatment is carried out every 12-14 days;
2. Concentration for spraying is 5 ml per 1 liter of water. For application, use sprayers with a fine nozzle so that the drug penetrates more easily into the leaf blade.

Previkur Energy: use of the drug

This fungicide was created specifically to protect garden and vegetable crops from various diseases. The working fluid based on the drug is used for preventive treatments and treatment of plants.

Previkur Energy is effective against:

• root and basal rot;
• downy mildew;
• late blight.

Typically, when the drug is first used, more than 85% of pathogenic microorganisms living in the soil die. And the second treatment activates the growth of cultivated plants, transplanted seedlings take root better, and the flowering of garden and vegetable crops becomes more abundant and active.

Standards for the use of Previkur Energy in agriculture

How does it affect plants?

The speed of action of the drug is about 24 hours. When applied to the soil during watering, the active substances quickly penetrate the root system and are distributed in the vessels of the plant.

When using the spraying method, the active substances penetrate the vegetative part of the plant through the pores on the leaves.

Active substances move in the acropetal direction, some of them accumulate in the leaves. Once inside the oomycete, they quickly block the synthesis of lipids, which are used to build cell membranes.

The mycelium cannot develop and grow, spores and pathogens of the mycelium are destroyed.

In addition, the drug has a positive effect on the immune system of the plants themselves. It causes changes in metabolism and stimulates growth processes in the root system.

This stimulates the protective properties of plants, and they become less susceptible to infection by bacterial or microbial microorganisms.

Advantages of the drug

“Previkur Energy,” according to gardeners, is an effective remedy that not only prevents the development of diseases, but also has a therapeutic effect when pathogenic signs appear on plants. Therefore, the drug has gained wide popularity among both amateurs and professionals.

Main advantages of the drug:

• effective against a wide range of pathogens;
• gives quick results;
• easy to use;
• has the ability to penetrate tissue and spread throughout the plant;
• maintains a long-lasting protective effect;
• does not cause addiction in pathogens;
• is not phytotoxic, therefore does not harm crops and crops;
• provides not only protection, but also stimulates plant growth;
• has a neutral level of acidity, so it does not affect the pH of the soil in any way;
• complete suppression of pathogens in greenhouse conditions;
• does not need to be combined with an adhesive, since the effect of the drug appears on the treated area after 30 minutes, and on the entire plant - within 24 hours.

Dosage per 10 liters

Instructions for use of the fungicide Previkur include dosage information. Consider soil and air humidity, climatic conditions, drug concentration, contamination and weediness of the crop.

It is not recommended to exceed the established application rates and number of treatments. To prepare the working solution, dilute 3 ml of Previkur Energy in 2 liters of water or 15 ml in 10 liters of water. The liquid is used at the rate of 2 liters per 1 m² of soil.

Costs:

1. For melons with powdery and downy mildew - 25 ml per 1 m² of soil.

Instructions for use

To ensure maximum effectiveness of the fungicide, strictly follow the manufacturer's recommendations given in the product data sheet. There are clearly defined usage standards and waiting periods that are worth paying attention to.

Basic principles of drug use:

1. The working solution should be prepared immediately before the procedure; residues should not be stored later.
2. The procedure should be carried out in dry, windless weather.
3. Initially, 1.5 ml must be dissolved in 100 ml of water, and then the total volume of liquid should be brought to 1 liter.
4. The effect of the drug is manifested at a temperature of no less than 12 and no more than 25 degrees Celsius.
5. The waiting period before harvesting is 20 days.
6. If necessary, the procedure should be carried out at intervals of 14 days.
7. To prepare the working fluid, it is recommended to use only plastic containers, as the drug causes metal corrosion.

According to the instructions for use of Previcura Energy, the drug should be used to protect cucumbers, tomatoes, melons and indoor plants, both as part of preventive and therapeutic measures. The protective effect of the drug occurs 3-4 hours after administration.

For tomatoes

To protect tomatoes from downy mildew, late blight and root rot, 3 ml / 2 l of water is required. This amount is enough to treat 1 m2 of area.

The drug is scattered immediately after sowing the seeds. Another procedure is carried out two weeks later. If the vegetables were grown in seedlings, they are watered with the solution after transplanting. Then the crops are processed at intervals of 14 days.

For tomatoes in the greenhouse

These vegetable crops are treated with Previkur Energy against:

• peronosporosis;
• radical decay;
• root rot;
• late blight.

To prepare the working fluid, dissolve 15 ml of the drug in a bucket of water. The resulting solution is poured into the soil after planting the seeds in the beds. The treatment is carried out once, 2 liters of working solution are needed for each square of area.

For tomatoes in open ground

These vegetable plants in open ground are treated with Previkur Energy fungicide against root rot, downy mildew, late blight, and root rot. To prepare a working solution, dissolve 30 ml in 20 liters of water.

Transplanted seedlings are sprayed 3 days after planting. The next few treatments are carried out during the period of active growth of green mass with a break between treatments of 12-14 days.

For cucumbers in greenhouses and open ground

A similar proportion and technology is used to treat cucumbers against the same fungal diseases. The same applies to peppers, eggplants and watermelons.

However, to protect potatoes from late blight, a more concentrated solution is used - 5 ml of the drug per 1 liter of water. The bushes are sprayed every 10-14 days.

For orchids and indoor plants

Healthy or already sick orchids are given the drug Previkur to prevent and protect against root rot, stem rot and other diseases caused by fungi or bacteria. It is also suitable for other plants including vegetables and garden crops.

Previkur is available in the form of an aqueous concentrate. The duration of exposure depends on environmental conditions, as well as on the general condition of the plants and averages 2-3 weeks. The drug is not addictive to fungi and bacteria.

The active ingredient is hydrolyzed in a slightly alkaline environment. Make sure the aqueous solution is slightly acidic or neutral. Tests for measuring pH can be purchased at pharmacies or aquarium supply stores.

Treat plants by spraying or watering in the doses indicated on the packaging, strictly adhere to them.
To spray, use a fine spray that produces a cloudy stream. When watering, the orchid roots must be moistened with water before treatment to achieve maximum effect. This will also help the drug penetrate the base better.

The drug should be stored in its original packaging, out of the reach of children and animals. Use personal protective equipment. Hazard class 3 (low danger).

For roses and other flowers

At the first signs of caries or to prevent it, use a standard solution: 3 ml of the drug per 2 liters of water. The soil should be watered, and the above-ground parts of the roses should be sprayed with a fine spray bottle.

If there are already signs of plant rotting (darkening, softening of tissues, loss of turgor), cut off the affected areas and treat them with an antiseptic before spraying. In the case of root rot, a similar treatment is carried out by removing rotten roots followed by disinfection. In this case, you still need to treat the substrate with a fungicide, as well as disinfect the pot (if the rose is indoors).

Similar technology is used for the treatment and prevention of other flowers. The proportions will also be standard: 3 ml/2 l of liquid. As with roses, areas damaged by rot should be pruned.

For strawberries

A feature of the use of fungicides when growing strawberries is the mandatory tillage of the soil. Berries inevitably come into contact with the soil in which they grow. Therefore, in case of infection, this nuance must be taken into account.

For preventive purposes, strawberries are processed every 2 weeks. Spraying can be used alternately with root watering.

For watermelons and melons

To protect these cucumber plants from powdery mildew, they are sprayed with Previkur Energy fungicide.

The working fluid is prepared as follows: 25 ml of the drug is diluted in 20 liters of water. In total, several procedures with an interval of 12-14 days.

For potatoes

This crop requires protection from late blight. The concentration is higher - 5 ml per liter of water. Plants are sprayed systematically several times during the summer, maintaining intervals between treatments of 14 days. The total number of irrigations using VC does not exceed five times.

Some varieties and hybrids of potatoes exhibit excessive sensitivity to the drug (the appearance of burns on the leaves). Therefore, it is recommended to first test the composition on one plant, wait 2-3 days, and then apply it against late blight on all ridges.

Precautionary measures

Previkur Energy belongs to toxicity class 3 drugs, therefore, if all processing rules are followed, it does not pose a danger to human health. But when it comes into contact with the mucous membrane, the drug causes irritation.

Basic precautions when working with working fluid.

1. To carry out the procedure, it is recommended to use special clothing, goggles, a respirator and gloves.
2. Do not smoke or eat during treatment.
3. Upon completion of the procedure, rinse all instruments with running water and take a shower.
4. Protective clothing must be soaked in a soda solution for 3 hours and then rinsed additionally.
5. If the working fluid comes into contact with the skin, immediately rinse the area with plenty of water.

Treatment should not be carried out near fisheries. You should also limit the number of bees for 3 hours after the procedure.

Duration of action

The activity of the drug depends on climatic conditions, since heavy rainfall washes Previkur components from the soil and washes its particles from the root system.

The degree of infestation should also be taken into account. During widespread outbreaks of infection, the duration of action of the substance is reduced, since it is actively used to destroy microorganisms.

The average duration of action of fungicides is 2 weeks. In the presence of the unfavorable factors described above, this period is reduced by 3-4 days, so secondary treatment should be carried out earlier.

Fungicide analogues

If Previkura is not available in the store, you can use other fungicides to combat fungal diseases.

The following drugs are analogues of Previcura Energy.

1. "Quadris" is a drug belonging to the group of strobilurins. It has a preventive and therapeutic effect against a complex of diseases. Validity period: 7-12 days.
2. "Strobi" is a local-systemic type of drug. The active ingredient is kresoxymethyl. The protection period is 7-14 days.
3. "Topsin-M" is a systemic fungicide with the active component thiophanate-methyl. The drug is highly effective as a prophylactic and therapeutic agent at the initial stage of the spread of pathogens.
4. "Alyet" is a systemic drug whose active ingredient is fosetyl aluminum. In addition to the protective effect, the fungicide increases the resistance of crops to the negative effects of pathogens in the future.
5. "Bactofit" is a biofungicide that has a gentle effect on crops. As a result, it is effective to use the product during the period of fruit ripening, when it is no longer possible to use chemicals. The waiting period is 3 days.

Previkur Energy is not a budget product, but by using it on your plot, you can be sure of getting a good harvest. But you should understand that maximum results can only be achieved by following all of the manufacturer’s recommendations.

Toxicity and safety precautions

Previkur Energy has a hazard class of 3 for humans (moderately toxic). Hazard class 3 for bees. It is not phytotoxic. It is prohibited to use it in the sanitary zone of fishing reservoirs! At a concentration of up to 0.2%, the drug is relatively safe for the predatory mite Typhlodromus, which regulates the number of spider mites.

Treatment should be carried out using traditional protective equipment: gloves and a respirator, but do not forget that no pesticide can be completely safe. The active substance Pervicura may cause irritation to the skin and mucous membranes. There is no specific antidote for oral administration; in case of accidental ingestion, rinse the stomach and seek medical help.

Store the drug in a dry place, preferably at a temperature from 0 to +25°C, away from food and medicine, out of the reach of children and pets.

Pros and cons of the product

Using Previkur means remembering that the plant is exposed to a serious chemical composition. Do not forget that the substance not only actively protects the culture, but can also cause harm. Hence, a mandatory condition arises: to study the positive qualities and negative effects of the drug. And there are plenty of them.

But let's start with the positives:

• actively used against root and basal rot of late blight;
• has increased absorbency. Tissues quickly absorb the substance (up to half an hour);
• If necessary, quickly apply the protective properties of the drug, it is allowed to water the plants. At the same time, Previkur actively protects, translaminar activity is at a high level;
• when infection occurs, but without knowledge of the classification of fungal infection or other diseases, the user may not be afraid to use the drug. Since the active substances destroy most of the known diseases;
• no addiction to the substance is observed. Hence there is a full opportunity to use the product repeatedly;
• phytotoxicity is not observed;
• accumulation of D-substances is excluded;
• The substance belongs to the new generation of drugs.

Another advantage of using this product is the type of product – a concentrate in liquid form. This allows you to store the purchased drug and use it for its intended purpose quickly and easily.

Among the negative effects of using Previkur, quite serious disadvantages are noted. And the first disadvantage can be considered the ban on the introduction of bulbous plants. The substance is also not suitable for root crops. There are restrictions on the use of fungicide for vegetable and fruit crops.

But the main negative point was the requirement for preparing a working mixture. Or rather, to the water in which the product will be: the indicators are pH – 5.5. As these indicators increase, efficiency decreases greatly. If there is an alkaline structure, there will be no benefit from the additions.

Compatibility

This fungicide is not compatible with fertilizers . With traditional treatment methods, the effect is enhanced when mixed with contact fungicides.

The need to adjust the pH when preparing tank mixtures in order to avoid destruction of the active substance (hydrolysis occurs in a slightly alkaline environment). Therefore, when diluting the solution, you MUST use an acidifier!

Previcur solution is corrosive to metals other than stainless steel. Therefore, the working solution should be diluted in plastic containers.

Reviews

Summer residents highly appreciate Previkur Energy. They emphasize that the product is effective and does not emit an unpleasant odor. But they say that you need to carefully select the stakes (Anatoly, Moscow region).

Unfortunately, sometimes in advanced cases it does not help. Therefore, you need to be able to identify the signs of the disease in time - this will help to achieve a better result.

“I tried to cure potato late blight with Previkur, but the situation had already gone too far and it didn’t work. Probably, the drug should be used in the early stages of the disease” (Nikolai, Leningrad region).

It is noted that the price of the drug is high, but it is worth every ruble spent. The effect is truly phenomenal.

“At first I didn’t want to buy this drug, because it is very expensive. But the fungus completely tormented me, and I bought it. I didn’t regret it: the disease quickly subsided. Now I will use it constantly” (Irina, Krasnodar).

Russian analogues, what can be replaced

Today, it is almost impossible to find analogues of the drug Previkur Energy. There is only one option: spraying the plants can be done using a drug similar in effect to Energodar. It also contains two main substances.

Difference from analogues: it can be combined with some solutions for treating plants: fertilizer mixtures, contact substances.

Advantages and disadvantages of a fungicide

The main positive qualities of the fungicidal drug Previkur Energy include:

• quickly absorbed into leaf blades, actively moves with cell sap through the vegetative part and root system of crops, and can linger in the foliage;
• effectively destroys not only the fungus, but also its spores;
• helps increase plant immunity;
• protects most garden and vegetable crops from many diseases;
• pathogenic microorganisms do not develop resistance to the drug, so it can be used repeatedly during the summer season to treat cultivated plants;
• the product is not phytotoxic.

Among the disadvantages of Previkur Energy it should be noted:

• You cannot spray strawberries, strawberries, bulbous crops and other root vegetables with this preparation;
• to prepare the working fluid, you need to use water with a certain acidity level (up to 5.5, not higher);
• Previkur Energy is not compatible with fertilizers;
• burns may appear on the surface of leaf plates and on human skin;
• high cost of the fungicidal drug.

It is not recommended to spray with this fungicide during the day; it is better to do it in the morning or evening.

What can the drug be mixed with?

Previkur Energy fertilizer can be safely mixed with a variety of pesticides and fungicides. For example, such as “Topsin-M”, “Thanos”, “Alirin B”, “Oxyhom”.

Mixing fungicide with highly alkaline preparations and fertilizers is strictly prohibited. For better reliability, perform a drug compatibility test before work.

What is included in the fungicide and how does it work?

The initial goal of development was aimed at combating black spotting. During research and further use, it was found that the drug is effective not only against this disease, but also many others of a similar origin.

Previkur is based on carbamate - promocarb hydrochloride. During the improvement of the drug, the phosphorus organic compound FOS was added to it, and unexpectedly a fundamentally new composition was obtained, significantly different from the original one. It was called “Previkur – Energy”.

Tip #1 . When choosing one of the means, it is important to consider that there are significant differences between them. The same characteristics are the period during which the effect of each of them manifests itself, as well as the period of protection against infection.
