Hazard assessment of pesticides’ application in agroecosystems

Abstract

Abstract The danger assessment of using pesticides and the effectiveness of reducing the pesticide load in agrocenoses of grain crops and fodder beet according to the indicators of predicted pollution and agro-eco-toxicological index (AETI) was carried out. A significant decrease in the predicted agrocenoses' contamination indicators with pesticides and AETI was found with a decrease in the fungicides consumption rates by 50% and insecticides by 20% when combined with silicon compounds. The comparison of indicators of predicted pollution and AETI for grain crops agrocenoses in different natural and climatic zones was carried out. The greatest danger is the use of pesticides in the dry-steppe zone of chestnut soils due to their low self-cleaning ability.
