Abstract: Determined the agroecological assessment and economic efficiency of growing corn for grain in permanent sowing under various plant protection systems, to analyze economic indicators and the structure of production costs. In the conditions of the Left-Bank Forest-Steppe of Ukraine, in the technology of permanent sowing of corn for grain, the ecological and economic assessment of the application of soil (Harnes, Stomp 330) and post emergent (Callisto 480 SC, Milagro 040 SC, Dianat, Esteron 60) herbicides was determined. The hazard degree of the use of herbicides and agroecotoxicological index are calculated according to sanitary-hygienic and ecotoxicological indicators. The indicators of economic efficiency of technologies for growing corn for grain under various plant protection systems are calculated. According to sanitary-hygienic and ecotoxicological indicators, Harnes is classified as dangerous; Stomp 330, Callisto 480 SC, Milagro 040 SC, Dianat, Esteron 60 — are moderately dangerous. The use of herbicides in permanent crops is the most effective and cost-effective technological measure with a share of conditionally net profit in the total cost of gross output of 10–79%, depending on the chemical preparation. On the average, the share of expenses for chemical plant protection products in the technology of growing corn for grain is 8.5–23.1%. When using soil and post emergent herbicides, a favorable ratio is obtained between the cost of gross output and the cost of chemical plant protection products against weeds. The level of pollution of the agrolandscape when making the specified range of herbicides is low risk. It was determined that in the technology of growing corn for grain, the highest economic efficiency (minimum cost of 1067 and 936, UAH/t, conditionally net profit of 32063 and 36027 UAH / ha, profitability of 322 and 381 %) is achieved by applying the Harnes soil herbicide with the addition of an post emergent herbicides Callisto 480 SC and Milagro 040 SC.
