It was found that on winter wheat crops the technical efficiency of protection systems with the use of new biological or chemical drugs against pathogens was 20.7-83.6 and 59.2-100%, on winter barley - 22.8-77.8 and 54 , 2–96.9%, on corn - 33.9–42.9 and 50.0–78.6%, respectively.The technical efficiency of new biological or chemical preparations in the systems of protection against phytophages was 16.6–52.1 and 51.1–98.2%, respectively, on winter wheat, 31.8–62.3 and 72.8–98.5%. on winter barley and 29.6–72.2 and 58.8–96.8% on corn. The use of biological products in the system of protection in the fight against diseases and pests on winter wheat, winter barley and corn ensures the preservation of grain yield by 4.7-5.8, 4.2-8.1 and 7.5-10.1% and increase the conditionally net profit by 1061–1423, 810–1347 and 2856–5088 UAH / ha, respectively.The use of chemicals in the system of protection in the fight against diseases and pests on winter wheat, winter barley and corn allows to obtain much higher additional yields, respectively - 8.4-12.9, 8.1-16.9 and 17.3-21 , 6% and increased the net profit by 455–2683, 303–1511 and 3782–8147 UAH / ha.
