Melnychuk F. Scientific basis of the phytosanitary condition of irrigated agroecosystems

The toxic effect of neonicotinoid insecticides on Daphnia magna, Eisenia fetida and soil microflora was analyzed. It was found that the group of phosphate-mobilizing bacteria increased its number under the action of all investigated active ingredients of neonicotinoid insecticides: thiamethoxam, thiacloprid and clothianidin. It is established that changes in soil moisture caused by irrigation have led to the transformation of the structure of complexes of harmful organisms of corn, winter wheat, sunflower. It is shown that irrigation in combination with other agricultural techniques, is a key factor in the intensification of growth processes and the formation of grain corn productivity. The use of insecticides through the drip irrigation system is a promising area in plant protection and can be successfully used to protect crops from various species of phytophagous insects and diseases. The advantage of such systems is the ability to quickly apply pesticides at a convenient time for the farmer, regardless of weather conditions.
