The drug Ridomil Gold: use for grapes, tomatoes, cucumbers, potatoes, flowers and other plants

Description of the drug

Ridomil Gold MC belongs to the fungicidal group of systemic contact action. It is presented on the market by Syngenta (Switzerland), produced using the latest PEPIT technologies.

It is based on two active components:

• mancozeb (640 g/kg) – provides external protection;
• mefenoxam (40 g/kg) – for internal protection.

Thanks to the presence of these components, Ridomil has systemic and translaminar properties. This allows you to plan a plant treatment schedule in advance, taking into account the characteristics of the crops, stages of the growing season, weather and climatic conditions of the area.

Purpose

Instructions for use of the drug Ridomil Gold state that the fungicidal drug is suitable for preventive and therapeutic control of the most common fungal plant diseases. In particular, the fungicide has a beneficial effect when:

• peronosporosis, affecting onions and cucumbers;

• downy mildew on grape plantings;

• late blight that appears on tomatoes and potatoes;

• Alternaria blight, which also affects tomatoes and potatoes.

You can purchase the fungicide on the gardening market in two forms - Ridomil is produced in the form of beige granules or light yellow powder. The product is usually packaged in small plastic bags of 50 g and 25 g; this amount is quite enough to treat small areas.

If you plan to use the drug on a large field or in a large greenhouse, then it is better to purchase Ridomil Gold in wholesale quantities of 1 kg or more.

When is the use of a fungicide indicated on grapes and other crops?

The drug copes well with the following tasks:

• late blight in tomatoes and potato roots;
• Alternaria blight in tomatoes, rapeseed and potato roots;
• black rot in grapes;
• downy mildew in onions (except for feather varieties), tobacco and cucumbers;
• mildew in grapes;
• downy mildew in cucumbers, hops, rapeseed, onions (except for feather varieties);
• gray rot in grapes and rapeseed;
• white rot in grapes.

The drug is also used to combat late blight and powdery mildew. But since these plant pathologies go beyond the scope of application of this fungicide, there is no need to talk about particular effectiveness - in this case, everything is individual and symptomatic.

The combination of active ingredients Ridomil allows you to fight diseases and carry out preventive measures to prevent them in any weather conditions without loss of effectiveness.

The drug is toxic and classified as hazard class II

Instructions for use of fungicide Ridomil Gold

As mentioned earlier, Ridomil has its own breeding characteristics for each specific crop. The degree of consumption of the drug and the number of sprays depend on the growing season of the plant and its type - fruit, berry or root crops.

How to breed for grapes

Main article: Ridomil for grapes

To process grapes, 2.5 kg of granules are used per 1 hectare of area. This is approximately 900 liters of solution. This culture will require 3-4 procedures. Moreover, the latter should be done 2 weeks after flowering.

The result of using Ridomil on grapes will become noticeable 21 days after the first spraying.

For strawberries

Main article: Application of Ridomil Gold for strawberries

In the case of strawberries, Ridomil is not used entirely for its intended purpose. This product is actively used by gardeners in late autumn to ensure better wintering of bushes. Fungicides such as Switch, Topaz, Quadris cope better with berry diseases.

For tomatoes

Main article: Tomato processing

The solution for processing tomatoes is prepared based on the following proportion: 400 liters per 1 hectare of planting area. Tomatoes are sprayed 3-4 times with an interval of 10 days. In the case of tomatoes, it is recommended to carry out the procedures in sunny weather.

For cucumbers

Main article: Ridomil Gold for cucumbers

Cucumbers use a small amount of the drug – the same 2.5 kg per 1 ha. This is about 400 liters of working solution for the specified area. Bushes should be sprayed three times a season. Moreover, the result of the treatment is visible already on the 5th day.

Garlic and onion

Main article: Treatment of onions with Ridomil

With the help of Ridomil, you can fight downy mildew on garlic and onions, but only those grown on heads, not on feathers. The consumption rate is the same as for cucumbers, but the waiting period is longer - 30 days.

The product is not used for onions.

For potatoes

Main article: Ridomil Gold for potatoes

To treat potato bushes, use a 0.5 percent solution. The number of sprayings is 3 procedures with a mandatory two-week interval between them. The result is noticeable after the first treatment.

Roses

Main article: How to use Ridomil Gold for roses

Garden and indoor flowers are sprayed with a solution of the drug of standard concentration. It is effective against rust on rose leaves. Treatment begins before the formation of buds and flowering.

Apple trees

Main article: How to breed Ridomil for apple trees

To protect trees from fungi, preventive spraying is done when the temperature reaches five degrees Celsius and significant changes are not expected at night (before the beginning of the growing season and sap flow).

It also protects the plant in rain, for a period of about two weeks (then the procedure must be repeated again). Leaves, shoots and soil are sprayed with it.

Advantages and disadvantages of fungicide Ridomil

Advantages of Ridomil over other fungicides:

• A relatively quick healing effect that affects even the most advanced stages of diseases;
• In addition to the destruction of pathogenic fungi on and in plants, Ridomil eliminates the possibility of their further reproduction in the treated area;
• Does not cause resistance in parasites at all;
• Undemanding dosage. The working solution will be effective at almost any solution consistency;
• This fungicide does not depend at all on the cultivation of the plants that are treated with it;
• Comfortable storage conditions. Radomil retains its performance from -15 ºС to +35 ºС. And also it does not burn and is not explosive;
• The effectiveness of the drug remains for 5 years after manufacture. But, provided that it is stored in original packaging within normal humidity.

But, in addition to its positive qualities, this fungicide also has several serious disadvantages:

• The drug Ridomil is toxic. In addition to plant tissues, he does not shy away from animals. May cause itching, swelling, and allergies;
• Small spectrum of action. Almost all the benefit of this medicine is the elimination of fungal diseases. But he does his job with interest;
• High price for a fungicide;
• In addition to parasitic fungi, the drug also destroys soil fungi and similar organic matter necessary for the plant.
• Ridomil, after treating plants with it, eliminates the possibility of using organic fertilizers;
• The substances that make up the fungicide are deposited in the soil and can have negative consequences when planting new plants;
• Weak phytotoxicity – inhibition of plant growth (but not fruit).

Processing consumption

Consumption rates for the drug during processing

Calculation of dosage and preparation of solution

The instructions for the drug Ridomil Gold describe in detail the application rate for certain crops.

Depending on the plant being treated, the consumption of Ridomil will be as follows:

1. For potatoes with signs of late blight or anthracnose - 400 liters per hectare.
2. In the event of an outbreak of similar diseases on tomatoes, the consumption of the working solution will also be 400 liters per hectare.
3. If signs of mildew (downy mildew) appear on the grapes, the use of 1000-1500 liters of solution per hectare of plantings is required, depending on the degree of damage.
4. Cucumbers and onions affected by peronosporosis are sprayed with a solution at the rate of 200-400 liters per hectare.

When processing, it is important to prevent the working solution from coming into contact with neighboring crops, so spraying is best carried out in calm weather.

There are clear instructions on how to dilute and use the working solution. To do this, you will need a special sprayer with a tank capacity of 5 or 10 liters. It is advisable to prepare the working solution in a separate plastic container, which will not be used in the future for storing food or drinking water.

First, fill the container with half the required water, pour in the required number of grams or kg of dry matter, mix the solution thoroughly and add the rest of the water. Next, the liquid is poured into the sprayer tank and used immediately.

The procedure for preparing the working fluid Ridomil Gold

The mixture for spraying the crop is prepared at the rate of 25 grams of the drug per 10 liters of water. If the plants that need to be treated are very heavily infected, then the amount of Ridomil Gold fungicide should be doubled. To prepare the solution, you need to fill ½ of the sprayer tank with clean water. Then you need to turn on the mixer and add a pre-calculated and measured amount of the drug to the water. Next, you need to continue filling the sprayer tank while simultaneously mixing the solution. To ensure the homogeneity of the prepared mixture, it is necessary to continue stirring the solution during processing.

Security measures

Pesticides are toxic to humans and the environment, so you should protect yourself. Handle plants with gloves, goggles and protective clothing in calm and dry weather. It is advisable to wear a respirator.

Spraying should be done in the morning or evening, since some active ingredients decompose in the light and will not be beneficial. When preparing the mixture, do not exceed the dosage. This is dangerous for humans and plants. When an overdose of copper-containing drugs occurs, crops, crops, and soil suffer. Land containing an increased amount of copper becomes unsuitable for use.

If the solution gets into your eyes, mouth, nose or skin, wash it off immediately with water. Pour the remainder of the unused pesticide into a deep hole away from the garden.

Tank mixtures are a powerful systemic preparation for the protection of garden and vegetable crops. Use it with caution, taking into account the compatibility of components and precautions.

Mode of application

For use in small areas, "Ridomil" is produced in convenient packaging of 20, 25, 50 g.
"Ridomil" is used according to standard regulations, coordinated with the flowering periods of individual crops. The effect of the drug should be excluded during the active flowering phase - from the beginning of the formation of buds until the formation of ovaries . The exception is potatoes, which are sprayed until the tops close in the rows.

The total number of treatments depends on the degree of infection of the plantings. Usually 2 to 4 sprayings per season are required:

1. First treatment . Preventive spraying during the phase of active growth of vegetative mass.
2. The second treatment is 2 weeks after the initial one.
3. The third treatment is prescribed when symptoms of fungal infection appear.
4. The fourth treatment is carried out 7-10 days after the third.

In any case, the last irrigation with fungicide is carried out no later than 2 weeks before harvesting.

Spraying of plantings is carried out in cool or moderately warm, windless weather, early in the morning, after the night dew has dried. Intense sap flow in the first half of the day promotes the distribution of the active substance throughout all tissues of the plant. If it is hot, treatment is postponed to the evening, since under the influence of sunlight, increased evaporation of moisture from plant tissue occurs, which reduces the effectiveness of the toxin. A drug sprayed in foggy weather or just before rain will inevitably be washed away by precipitation and will not have time to act. After complete drying, the active substance is no longer washed off from the surface of the sheet with water.

Treatment is carried out using a fine spray. Plants are irrigated until a continuous thin film of solution forms on the surface.

Tip No. 1: Before irrigating the so-called striped soil in a limited area of ​​land, you should cover the beds with early vegetables and green crops that cannot be processed with polyethylene or other impermeable material.

To prepare the solution, you need a special sprayer with a mechanical stirrer (built-in or submersible). Procedure:

When irrigating grapevines, especially carefully treat forks, internodes, and various irregularities in the stems, where fungal spores can hide.

• Pour half the required volume of water at room temperature into the spray bottle.
• Turn on the stirrer.
• Open the package of the drug.
• Add granules in small portions, stirring constantly.
• Without stopping stirring, add water in a thin stream to the required volume.
• Stir for another 2-3 minutes.
• Close the sprayer and immediately begin irrigating the plants.

The finished mixture can be stored for no more than 4 hours.

Composition of the drug Ridomil Gold

It is used to combat Alternaria, late blight, and downy mildew in vegetables and to destroy mildew on grape vines.
The action of the product does not apply to iodium pathogens.

Ridomil Gold is available in the form of powder or granules.

They contain 2 active ingredients: mefenoxam and mancozeb. They contribute to the complete protection of the plant: from roots to fruits.

Mancozeb and Mefenoxam

The two components listed above have an active effect on infected plants:

• Mancozeb : during the spraying process, it settles on the crop, providing external protection against fungal diseases.
• Mefenoxam . It works systematically. After spraying, complete penetration into the plant occurs. The component, moving through the tissues (captures both roots and fruits), protects them from diseases and infections.

Advantages

• It is highly effective in any development of the disease.

• Able to control the development of infection throughout the growing season.
• After treatment, all parts of the plant are protected from infection for a long time. Even if some parts of the plant were not directly hit.
• Resistant to moisture. Treated plants can be watered within half an hour. A sudden shower of fungicide is also safe.
• Safe for the crops being processed and their “neighbors”.
• The package with Ridomil Gold is convenient to store.

Flaws

• It is dangerous for fish and mammals, but not at all dangerous for bees. Therefore, the solution must not be allowed to enter the reservoir. Belongs to hazard class 2. When spraying plants, be sure to use protective equipment: gloves, mask, goggles.
• Low level of environmental safety.
• The packaging is not conducive to economical use.
• Cannot be used together with other chemicals.

Advantages of the drug

Basically, if you look at the reviews on the forums about Ridomil Gold, they are only positive. And indeed, the drug showed itself exclusively on the good side.

Benefits of the fungicide:

1. substances begin to work immediately after treatment, just 1.5 hours are enough for Ridomil Gold to spread evenly
2. distributed throughout all plant tissues, creating a protective coating on the surface;
3. the fungicide is safe for any garden crop and the environment;
4. treatment carried out in cloudy and damp weather is just as effective as in dry weather, because the product is not washed off and lasts for about 14 days;
5. excellent for prevention;
6. Ridomil Gold working solution is easy and simple to prepare.

Despite the safety, when working with Ridomil Gold you must take precautions:
store in a specially designated place, mix in containers not used for food, work with gloves (at a minimum). Dispose of away from water. When it is necessary to process a lot of m2, you should be mentally and financially prepared for a significant consumption of the drug.

Compatibility with other drugs

In most cases, Ridomil Gold MC is compatible in tank mixtures with insecticides and agrochemicals, with the exception of solutions with an alkaline reaction.

Do not use mixtures if precipitation occurs, the temperature of the solution increases, or a violent reaction occurs.

What can you mix Ridomil Gold with?

Examples of successful compositions are in the table.

Other effective combinations:

• Fitoverm, Topsin-M;
• Topaz, Aktara, Zircon (this is a fungicide, insecticide and growth stimulant, respectively);
• Ridomil Gold, Tiovit Jet and Albit;
• Biostat, Humat, Aquarin-Super;
• Albit, Ordan;
• Speed ​​+ Topaz, Horus, Fitolavin;
• Fitoverm, Topsin-M.

To protect the garden, recipes that involve the use of several drugs with different directions of action are suitable. Some should kill pests, others should cure diseases. To increase efficiency, you can mix Biostat and Agrovertin at the same time. They are compatible. The best fungicides are Skor and Topaz.

Agromedicine and Benomyl are combined with any pesticides.

If the drugs were selected correctly, the effect of their use will last up to 2 weeks. Another solution can be used after 5-7 days, not earlier.

When choosing the composition of the tank mixture, you should pay attention to the type of crop. For garden plants (potatoes, peppers, cabbage), a preparation consisting of:

• Horus, Thiovit, Iron Chelate;
• Urea, Ridomil, Immunocytophyte and Alatar;
• Kemira, Ordan, Aktara and Gumata.

For diseases of fruit and berry trees, it is better to use Horus. Spray after flowering. It protects against moniliosis, curly hair and clasterosporiasis. For quick results, use it in combination with Aktara, Ryazanochka and Urea.

For diseases and pests on berry bushes, it is better to combine the following drugs:

• Topaz, Karbofos, Sudarushka;
• Ovary, Thiovit, Kemira.

See the instructions for dosages.

Questions from gardeners about the use of "Ridomil"

Question No. 1. Is it possible to treat strawberries and garden strawberries with Ridomil?

It is not recommended to use pesticides on berry fields during the formation of ovaries and fruiting. As a last resort, fungicides with a short wait time can be used to ensure safe consumption of the fruit. Unfortunately, "Ridomil" is not one of them. It is permissible to treat berry crops with it only at the very beginning of the growing season, before flowering, or in late autumn when preparing plants for wintering.

Original and fake

The drug is produced by the Swiss industrial company Syngenta. Standard containers of 25 and 50 g. The average cost of 50 grams of the active substance is 200 rubles. If you see Ridomil Gold on the market costing 100 rubles per 50 grams, then you can be sure that it is a fake.

The problem with a counterfeit is that it is so high quality that it is almost indistinguishable from the original.

But still, there are some differences that will allow you to purchase a really good product:

1. Firstly, as we have already noted, this is the price. For a high-quality foreign pesticide, they will charge you a decent amount. Therefore, cheap Ridomil from Signetta is a real fake.
2. Secondly, fakes are produced in the form of ordinary powder. The original, in turn, has the form of granules.
3. Thirdly, there is a company logo on the original package. Counterfeits, most often, do not have this logo.

(!) Typical mistakes

1. 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.
2. 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.

Profit Gold or Ridomil Gold - which is better?

The presence of two components in the drug allows it to cover two directions of action.

1. The first active component, cymoxanil, penetrates under the outer layer of wood tissue, cleans the affected areas from fungal formations and prevents the subsequent development of this disease.
2. The second component, famoxadone, destroys the fungus along with the spores formed on the surface.

In a humid environment, the substance creates a protective stretchable film. In this way, the area of ​​action of the drug increases by spreading to areas that have not been treated or that have arisen during the period of development and growth.

Famoxadone is able to destroy the fungus at the cellular level; it is also effective against its spores.

Profit Gold is an analogue of Ridomil Gold, there is no difference in their use. Choose at your own discretion.

What diseases does Profit Gold fight?

"Profit Gold" destroys the simplest microbes that cause fungal diseases, including those resistant to other means. The drug is intended for use on any non-flowering plants.

The fungicide is intended for use on:

• indoor plants;
• flowers suffering from septoria;
• strawberries to combat brown spot;
• various plantings infected with powdery mildew;
• onions - effectively fights peronosporosis;
• grapes - helps against mildew;
• tomatoes - from late blight and stem rot;
• potatoes against Alternaria and anthracnose;
• beets.

Composition and properties

Most known fungicides use a contact method of action, that is, they destroy pathogenic fungi exclusively on the surface of the plant. Meanwhile, fungal spores that have penetrated deep into the tissues retain their viability during surface treatment and continue to develop inside the plant. To ensure guaranteed suppression of infection, a drug is needed whose effect extends to the intracellular space. Ridomil Gold is just such a systemic fungicide, consisting of two active components:

Advantages of "Ridomil" over analogues:

• rapid therapeutic effect (beginning of action – half an hour after application);
• effectiveness at any stage of the disease, even in advanced cases;
• complete elimination of the source of infection without the risk of relapse;
• lack of resistance (development of pathogen resistance to the active substance);
• spreading the therapeutic effect to untreated parts of the plant, including fresh growth formed after treatment with a fungicide;
• wide temperature range of storage (the beneficial properties of the drug are not lost at t -10… +35°C);
• ease of dosing - the concentration of the active substance in the solution is the same for all crops.

Important! "Ridomil" does not have a selective effect. This means that along with pathogenic fungi, beneficial microflora is also destroyed. It should be borne in mind that regular use, as well as overdose, leads to a deterioration in soil quality. Reclamation of soil poisoned by fungicide using humus, compost (see → recipe), and available biomass is impossible until the toxic substances have completely disintegrated.

"Ridomil Gold" for tomatoes. Eliminating the danger of late blight

The causative agent of this dangerous disease is the fungus Phytophthora infestans. The infected plant immediately becomes covered with brownish-brown spots, and its fruits or roots begin to rot. The development of the disease is usually provoked by prolonged rains in warm weather. Late blight cannot be cured. Crop losses in contaminated beds and plots can reach 50% or more. In order to avoid infection, in rainy summer conditions you should definitely use the drug “Ridomil Gold”. Its use in most cases guarantees complete safety of the crop.

Chemical compatibility

The drug can only be mixed with chemicals of the same group. After mixing, it is necessary to test the resulting product. To do this, you need to treat several leaves of the plant and look at the reaction. If the solution has a detrimental effect, then it is necessary to stop using it.

Ridomil Gold is qualitatively different from the drugs in its group. If you decide to use the drug with compatible chemicals, you should alternate treatments every 7 days.

Rules for using fungicide

As we already know, it belongs to the second class of toxicity. This means that the use of the drug requires strict adherence to safety measures. Otherwise, there is a risk of serious chemical poisoning.

Personal safety measures

Basic precautions when working with fungicide include:

1. Wearing protective clothing that covers all areas of the skin. In addition, it is important to wear a respirator, goggles and rubber gloves.
2. Do not allow the product to be near water bodies, as well as food and medicine.
3. Prepare the solution in a container specially designated for this purpose.
4. After treatment, you should thoroughly wash your hands and face.
5. If the chemical gets on the skin or mucous membranes, rinse the affected area under running water and consult a doctor.

Shelf life and storage features

Packaging with powder or granules is stored for 3 years from the date of production. The fungicide can be stored at temperatures from -10 to +30 °C in a dark, dry place. It is important to remember that the pesticide must be inaccessible to children and pets.

Rules for processing plants

Ridomil Gold MC instructions for use for vegetables and flowers are given below. To quickly distribute mefenoxam in the stems of the plant, treatment with Ridomil is carried out in moderately warm or cool weather. In hot and cloudy weather, spraying of crops is carried out in the evening, since transpiration during the day interferes with the spread of mefenoxam.

Onion and garlic beds

Do you use folk signs in gardening?

At the first symptoms of peronosporosis, fruits (not feathers) are treated with a ready-made solution at a rate of 25-40 ml per cubic meter. Further spraying is carried out every 1.5 - 2 weeks until the symptoms of the disease disappear. The period of protective action of one spray varies from 15 to 21 days.

cucumbers

Cucumbers are treated with Ridomil until downy mildew appears. The time interval between spraying is up to two weeks. The medicine is valid for up to 21 days for cucumbers. Dry matter consumption per 1 m2 is 30 ml.

Cucumbers are processed until peronosporosis appears

For potatoes

Spraying is carried out before the stage of fruit closure with a 0.5% solution for prevention. The drug is effective for two weeks. Consumption: per 1 hundred square meters 25 grams of substance. Ridomil acts against fusarium and alternaria.

For the vine

After the grapes bloom (at the 4-leaf stage), the vines are sprayed every 14 days. Consumption per 1 m2 is 150 ml. Ridomil is effective against mildew disease within 21 days from the date of treatment of the culture.

For tomatoes

Tomatoes are sprayed with Ridomil solution in sunny weather. The solution is prepared based on the proportions: 10 grams of medicine diluted in 4-5 liters of water. The plant is completely processed. Effect of the drug: 10-14 days.

Indoor flowers

Ridomil should not be used during budding, as the drug has a detrimental effect on plants during flowering (reduces development). Spraying is carried out with a mixture of 2.5 grams of Ridomil powder per 1 liter of liquid.

The above-ground parts of onions and potatoes are allowed to be processed, since the edible part of the crops is located in the ground.

Counterfeit and analogues

There are products similar to Radomil Gold, differing only in price, methods of application and some composition. Main analogues:

1. 
   Profit Gold. The drug contains cymoxanil, which actively protects from the inside, and famoxadone prevents infection from the outside. The drug begins to act after 3 hours of drying on the plant; it is not washed off by rain. In terms of duration of influence on the plant, the drug is somewhat inferior to Ridomil. Potatoes and tomatoes will have to be sprayed four times during the season.

2. Quadris. The drug is actively used for the prevention and treatment of fungal infections. A distinctive feature of the drug is its destructive effect on spores, which is important for grapes and tomatoes.
3. Previkur Energy. The drug is used to treat plants. It completely destroys fungal diseases. It is a liquid containing concentrated neutral hydrogen. In some characteristics it is superior to Ridomil.

Ridomil is very popular among consumers; it can be ordered on the manufacturer’s website and on specialized Internet sites. Its popularity has led to the spread of counterfeits.

First of all, the buyer should pay attention to the price: if it is significantly lower than on the manufacturer’s website, then you should not purchase this product from the seller. You need to pay attention to the appearance of the drug: the original is only granular, while the fake has the appearance of a powder.
