One of the most important problems of vegetable growing in protected soil is obtaining environmentally friendly products. This is achieved through the use of new generation drugs that are low-risk for the environment. The purpose of the study is to evaluate the effectiveness of the drug BFTIM Nova in the fight against cucumber diseases in protected soil conditions. The name of the fungicide is BFTIM Nova. Purpose – spraying the soil with a fungicide solution. The period of the experiment is 2023, June-September. The greenhouse is located within the city of Grozny. The results of vegetation experiments indicate that four times treatment of cucumber plantings with fungicides Serenada ASO, KS and BFTIM Nova provided high efficiency in hydroponics conditions and amounted to 78.4 and 89.9%, respectively. Under the condition of epiphytotic development of the disease, maximum protection was obtained after using a new two-component fungicide, the effectiveness of which reached 89.9%, and the increase in yield relative to the option without treatment was 24.1%. The data obtained allow us to assert that BFTIM Nova is an effective drug against root rot, basal rot and downy mildew of cucumber under different conditions of its development and its inclusion in the system of integrated crop protection in protected soil conditions can improve the phytosanitary situation in the greenhouse agrobiocenosis.
