Abstract:
During vegetation rape can be attacked by a complex of polyphagous pests, or less - pests with a narrow specialization nutrition. Integrated protection of rape requires the use of a complex of preventive measures: produce seeds in specialized households, compliance with all requirements for quality seeds etc. From agronomic measures an important role in limiting pest populations we have the following elements: rotation crop rotation with rapeseed return no sooner than 3-4 years, selecting successful predecessor (prohibiting cultivation of rape after rape or other cruciferous vegetables), isolation in space fields of rape seed, and other cruciferous common fields at a distance of not less than 1 km, in terms optimal sowing and harvesting, cultivation of resistant varieties. Polyphagous pest chemical control to different cultures is ensured by a large number of insecticides and rape culture these questions require a much larger study.
