Preparation of working solution
Preventive spraying with Poliram begins in early spring at the beginning of the growing season.For the whole season, 4 pulverizations are carried out with an interval of 8 to 10 days.
The working fluid of the fungicide should be prepared on the day of use, as it loses its properties during storage. For this, the sprayer is half-filled with water and the granules are dissolved in it. Then, stirring constantly, add liquid to the required volume. The result should be a homogeneous solution. The dose of the drug Poliram and the processing time are selected depending on the type of culture.

To prepare a working fluid, 40 g of dry matter must be dissolved in 10 liters of water (bucket). The potatoes are sprayed four times: before the tops close, during the bud formation, after flowering and during the appearance of the berries. The instructions say that the fungicide Poliram retains its effect for three weeks. For one square meter, an average of 50 ml of solution is consumed.
