Peronosporosis, which occurs in cucumber plants, is one of the most dangerous diseases, causing significant damage to the quality and quantity of the harvest. Chemical control measures are effective in timely protection of cucumbers from peronosporosis. Several drugs against this disease have been tested at different consumption rates. As a result, Score 250 em.k. (0.2 l/ha) and Fundazol 50% n.kuk. (1.0 kg/ha) Biological efficiency was achieved in the variants using fungicides up to 91.1%. In the protection of cucumber plant from peronosporosis disease Score 250 em.k. (0.2 l/ha) and Fundazol 50% n.kuk. (1.0 l/ha) has been proven to produce high and quality crops from the plant by applying fungicides in the morning or evening cool.
