Subject of research - corn, pests, diseases, spraying, herbicide, fungicide, insecticide, tillage. Research methods. The research is based on field experiments using the following methods: visual - to determine the phenological phases of growth and development of culture; estimated - to determine the development of diseases, pests, parameters of crop structure and grain yield, grain quality; chemical - to determine the content of nutrients in the soil; mathematical and statistical - to assess the reliability of research results; settlement and comparative - for the analysis of economic efficiency. The largest number of weeds was observed in variants without herbicide spraying during surface tillage and was 545.6 pcs./m2, which is 2 times higher than on the shelf (277.1 pcs./m2). The highest technical efficiency of herbicides of 96.8% was observed on the 14th day after spraying with shelf tillage. In variants without insecticide, the aphid infestation of corncob was 75-85%. The use of Belt allowed to reduce the population of plants by 3.5 times the pest. The technical efficiency of the fungicide Retengo against fusarium wilt was at the level of 87.1-90.0%, gray rot - 78.3-80.1% and helminthosporiosis 79.4-81.4% depending on the tillage. Yields at the level of 11.83 t / ha were observed with shelf tillage and intensive protection system. The lack of a protection system reduced this figure by 38.0-41.7%. The highest economic efficiency was obtained on the option of shelf tillage with integrated plant protection conditionally net income was 30130.0 UAH / ha, payback of additional costs - 3.
