Instructions for use of the fungicide Rovral, composition and form of release of the product

Rovral is a modern contact fungicide, used both in large greenhouses and farms, and in personal plots. The effectiveness of the drug depends on the correctness of its use, compliance with safety measures and storage. Below we will consider not only the composition, mechanism of action, advantages and disadvantages, but also instructions for the use of the fungicide Rovral, its compatibility with other drugs.

Composition, release form and purpose of the drug Rovral

The main active ingredient of this drug is iprodione. Its content is 50% (500 grams of active ingredient / kilogram of fungicide weight). Rovral is produced in the form of a wettable beige powder with a low odor. A standard pesticide package weighs 1 kilogram.

Rovral is used to combat such diseases of sunflower, cucumbers and protected ground tomatoes as seedling rot, phomopsis.

The mechanism of action of the fungicide

The pesticide applied to the parts of plants affected by fungal diseases has a two-level mechanism of action:

1. The active ingredient of the drug reduces the rate of germination of pathogen spores.
2. The pesticide blocks mycelium development.

Thanks to this mechanism of action, Rovral, when used correctly, causes weakening and then complete death of the pathogen.

Advantages and disadvantages

The advantages of Rovral include:

1. High efficiency.
2. Low toxicity to humans, beneficial insects, fish, birds, soil microflora.
3. Compatible with most modern pesticides.
4. Two-level mechanism of action.
5. No cases of drug resistance of pathogens.

From the disadvantages of this fungicide, a sufficiently large package in weight should be distinguished, containing 1 kilogram of wettable powder. This amount of pesticide is quickly consumed in large greenhouses and farms.

In private plots, only a small part of it is used from an open package, while the rest is stored open for a short time.

Consumption rates

The consumption rate of the Rovral working solution depends on the method of its application:

1. Disinfection of the wells before planting seedlings - 500 milliliters / well.
2. Watering vegetative plants at the root - 150 milliliters / plant.
3. Seed dressing - 10 milligrams / kg of seeds.

When smearing stalks affected by rot, a mixture of dry powder with lime materials (chalk or lime) is used in equal proportions.

How to prepare a working solution

Rovral's working solution is prepared as follows:

1. Water is poured into a clean and dry container, the volume of which should be equal to or slightly less than half of the amount of working solution required for processing.
2. The amount of fungicide previously weighed on an electronic scale is poured into the water. To prepare a standard 0.1% solution, 1.0 gram of the drug is poured into 1 liter of water.
3. The powder is stirred with a wide wooden stick until completely dissolved.
4. The container is filled with water to the volume of the working solution required for processing.
