Fungal diseases threaten plants in the garden and vegetable garden. For prevention and treatment, special drugs are used - fungicides, the active substances of which block the growth and development of infections.
Ridomil Gold works well in vegetable plots and gardens, which is characterized by a systemic effect and effectiveness in the fight against many diseases. The mixture of products comprehensively protects plants and is used for treatment; the main thing is to follow the dosage and instructions for use.
Composition and mechanism of action
The fungicide consists of two main components listed in the instructions, which provide Ridomil with a systemic effect and high efficiency when applied.
The composition of the fungicide includes:
- mancozeb - the substance fights fungal spores on the surface of plants, the concentration of mancozeb is 640 g per 1 kg of product;
- mefenoxam - penetrates into the internal tissues of plants and prevents the development of pathogens at the cellular level, the concentration is only 40 g per 1 kg of product.
Ridomil, used in the treatment of cultivated plants, has a complex effect:
- During treatment, the active ingredient mancozeb forms a durable protective layer on the surface of the stems and leaves and thereby blocks the access of oxygen and the ability of fungal spores to reproduce. As a result, microorganisms cannot carry out their vital processes.
- Mefenoxam penetrates deep into plants through the pores and moves in the tissues along with plant juices. If pathogenic organisms are present in the cells of potatoes, tomatoes and other plants, mefenoxam reliably destroys them.
Ridomil Gold has a valuable property - fungal spores do not adapt to the action of active substances, so if necessary, the product can be used regularly.
From what diseases
Most often, the drug "Ridomil Gold" is used for the prevention of: late blight and alternaria blight of tomatoes or potatoes, peronosporosis of cucumbers and onions, and powdery mildew of grapes.
Ridomil is very effective against peronosporosis fungi. It is not used against powdery mildew. The drug is effective against Mildew (downy mildew of grapes), this dangerous disease can destroy the entire grape harvest in just a few days and is characterized by the following symptoms: like cucumbers, the leaves of the vine are first covered with an oily yellow coating on top and fungus below, then they dry out and fall off. The skin of infected grapes becomes wrinkled. As a result, they acquire a pear-shaped shape. Only ripe berries are not affected by powdery mildew. To prevent such troubles, Ridomil Gold should be used. Its use on grapes is considered even more effective than traditional Bordeaux liquids.
Characteristics of the drug Ridomil Gold
Let's look at the description of the drug. Ridomil Gold MC, VDG contains metalaxyl, mancozeb and is effective in the fight against various fungal diseases, as it protects the vegetative parts of the plant, that is, leaves and stems. In addition, it has a positive effect on fruits, tubers and berries. It is used in the fight against powdery mildew, rust, mildew and many other diseases of vegetables, fruits, berries and flowers. It quickly decomposes in the soil, protecting the plant inside and out.
The manufacturer of the drug is Swiss, which produces Ridomil Gold in packaging of 25 and 50 grams, and for industrial purposes from a kilogram. You can buy it on the manufacturer’s official website or in specialized online stores. So how much does the drug cost? The price for 50 grams is about 150-200 rubles, and the cost for 1 kg starts from 10 dollars. If you visit many forums for summer residents and gardeners, you will find only positive reviews for this fungicide.
Instructions for use
The solution is prepared in the morning or evening. On cloudy days, it is advisable to spray the crop in the morning so that the drug is completely distributed throughout the plant during the day.
In case of heavy morning dew, treatment is postponed to a later date.
In hot weather, spraying of vegetables or shrubs is carried out in the evening so that the active substance is better absorbed into the plant tissue. Do not forget to take into account the characteristics of the growing season, since at the beginning of budding and ovary formation, the fungicide is not used. It is acceptable to use Ridomil during potato flowering, since the tubers are edible, but not the above-ground parts.
For tomatoes
The insidious late blight causes great damage to tomatoes. Infection most often occurs in the second half of summer, when the rains and first cold weather begin. During an unfavorable season, late blight appears on tomatoes earlier, so it is important to notice signs of infection in time and begin treatment.
The dosage is standard, the consumption of the working composition is 30 ml per square meter of crops. Spray 2-3 times, the interval between spraying is 10 days.
For grapes
Grapes are mainly affected by rust and powdery mildew. To eliminate it, make a solution of 10 liters of water and 25 g of Ridomil Gold. In some cases, to treat grapevines, it is recommended to use a double amount of Ridomil Gold - up to 50 g for the same amount of water. Sufficient for 100 m2. Use only in dry, windless weather.
Spraying of grapes with Ridomil Gold should be carried out evenly.
Treatments are carried out according to the calendar, during the active growing season and at the stage from germination to 4 leaves. The break between procedures should always be 7-10 days.
For roses
The mixture for spraying the crop is prepared at the rate of 25 grams of the drug per 10 liters of water. If the treated plants are very heavily infected, the amount of Ridomil Gold fungicide should be doubled. To prepare the solution, fill ½ of the sprayer tank with clean water.
Then turn on the mixer and add the previously calculated and measured amount of product to the water. Continue filling the spray tank while stirring the solution. To ensure the homogeneity of the prepared mixture, continue to stir the solution during processing.
For cucumbers
For this crop, use is advisable in case of infection with the peronosporosis fungus. Usually the first signs are visible already at the beginning of flowering of cucumbers, so spraying is carried out immediately.
Standard solution, use 20-35 ml of working composition per 1 sq. m. Spray three times, intervals between treatments are 14 days.
Harvesting of green vegetables is permitted no earlier than two weeks after treatment of plants with Ridomil Gold.
For potatoes
The drug is used for spraying against fusarium and alternaria (prevention). These diseases affect all parts of plants:
- roots;
- stems;
- tubers;
- leaves.
Standard solution, 25 grams per 10 liters of water. Apply the spray according to the diagram:
- The first treatment is before the potato tops close.
- The second one is in two weeks.
- The third - 14 days after the second.
Per hectare 400 liters of solution in the tank. After two weeks of planting, spray with a contact fungicide (for example, Bravo).
For strawberries
In the case of strawberries, Ridomil is not used entirely for its intended purpose. This drug is actively used by gardeners in late autumn to ensure better overwintering of bushes. To combat berry diseases, it is better to use fungicides such as Switch, Topaz, Quadris.
For onions and garlic
To process onions and garlic, prepare a working solution of 10 g of the drug and 100 ml of water. When it is completely dissolved, add another 4 liters of water to the container and stir the solution constantly. The consumption when spraying these crops is a bucket per 100 square meters. Work is carried out in calm, dry weather, only in the evening or in the morning. The finished composition is applied during the day. Plant stems must be moistened on both sides to enhance the effect of the drug.
Since Ridomil Gold pesticide is toxic, precautions must be taken when handling. For example, it is important to use a respirator, safety glasses and protective clothing. If drops of the chemical come into contact with your skin, rinse it under running water. If you accidentally swallow a chemical, seek medical attention. Before this, drink a few glasses of water and 4-5 tablets of activated carbon, and then induce vomiting. Garlic and onions can be eaten only 2-3 weeks after spraying.
For the apple tree
To protect trees from fungi, carry out preventive spraying when the air temperature reaches five degrees Celsius and no significant changes are expected at night (before the beginning of the growing season and the movement of sap).
It also protects the plant from rain for about two weeks (then the treatment should be repeated). You can spray leaves, shoots and soil.
For indoor plants
Ridomil Gold is used mainly on vegetable crops. However, according to the instructions, the fungicide is suitable for treating indoor plants and flowers and helps eliminate most fungal diseases.
Instructions for use of Ridomil Gold MC will look slightly different than for vegetable crops. In particular, for spraying you will need a much smaller amount of solution, although the proportion will remain the same; dilute Ridomil at the rate of 2.5 g per liter of water. Indoor flowers are sprayed twice per season, the first treatment is carried out before buds appear on the stems. The interval between procedures is also 2 weeks.
(!) Typical mistakes
- There is an opinion that “Ridomil” can be used to treat indoor flowers. This is a dangerous misconception. When irrigating plants with Ridomil, the active component mancozeb forms a film on the surface of the leaf, which begins to disintegrate after about 10 days. As a result, a toxic substance (hazard class 2!) ends up indoors, negatively affecting humans and domestic animals. There are many other, less dangerous means to combat diseases of indoor plants.
- Another common mistake is using Ridomil in the garden as a remedy for fruit rot, scab, and moniliosis. The fact is that mefenoxam has increased penetrating ability into all parts of the plant, including the fruits. Eating fruits and berries with high concentrations of toxic chemicals is dangerous to health.
How to spot a fake
Today, counterfeit products are of such high quality that the average person can easily make a mistake. For example, on the packaging of the fake and the original there is an identical photograph, production date and instructions, but there are still differences between the miniatures.
The counterfeit comes in larger packages and is also available in powder form, although the foreign formulation comes in granules. Photos of the fake can be seen on the Internet.
When purchasing Ridomil Gold Syngenta, a person should pay attention to the following:
- The price is never the minimum for a high quality imported product.
- The composition must be granular.
- Each package indicates the production date and expiration date.
Only a high-quality product can protect the plant from fungal infections and protect it from future ailments.
Compatibility
Ridomil Gold is perfectly compatible with other drugs, but it should not be mixed with these chemicals.
If you have an idea to mix it with another composition from this group, you need to check the mixture for compatibility. To do this, select a separate place and spray the cultivated plant. If the reaction to the treatment was positive, a cocktail of both drugs can be used on other plants. However, if the reaction to the spray was negative, the drugs are used separately. The interval between them must be at least 7 days.
Ridomil Gold can be compared to Topaz and Skor, which protect the plant from rust, mildew and late blight. If we compare it with other chemicals, it provides reliable plant protection for up to 18 days, which is slightly higher than that of Ridomil Gold. Both of these formulations can be used interchangeably with Hom, which is easily combined with other types of pesticides, as well as insecticides and various fertilizers. In addition, Hom combines well with drugs from the dithiocarbamate group, which helps avoid burns on the leaves. This composition has a long shelf life and is used together with Ridomil Gold, Epin, Fufanon, Tilt 250. It is prohibited to combine it with alkalis. Therefore, there is no need to spray with copper oxychloride and other similar chemicals before treating with Hom. The change rids the cabbage of black and brown spots.
Analogs
The most effective substitutes for the fungicide Ridomil Gold will be:
- Quadris;
- Previkur Energy;
- Profit Gold.
A little about each of them.
Quadris is well suited for controlling fungi on plants. The spray has a destructive effect on fungal spores. It is suitable for use in greenhouses, conservatories and outdoor areas. Quickly eliminates rhizoctonia, powdery mildew, powdery mildew, apple scab, etc.
Previkur Energy is a liquid with a high concentration of neutral hydrogen. There are 2 active ingredients. It not only kills fungi and stops the disease. It also greatly stimulates the growth of green roots. It has a wider spectrum of action than Ridomil.
Profit Gold contains cymoxanil. It penetrates plant tissue and protects them from the inside.
Another important component, famoxadone, provides external protection. Profit Gold is perfectly fixed on the surface of sheet plates and is not washed off by rain or other precipitation.
It begins to act 3 hours after spraying. The duration of the protective effect is 10 days and is shorter than for Ridomil.
