Effective protection of grain crops from pests

Abstract Plant protection products are currently the main part of crop cultivation technologies not only in Krasnoyarsk territory, but also around world. The most promising way to protect plants from pests is an integrated system that involves use chemical control agents cases where pest population exceeds economic threshold, and effectiveness increase natural mechanisms for regulating number carried out using agro-technical biological methods suppression. As a result conducted research, it was revealed protective measures allowed reduce losses by 10-15 %. During study period, all recorded on grain crops (excluding cereal flies) did exceed threshold harmfulness, necessary take into account their complex impact especially (aphids, thrips large nutmegs), which themselves massively spread more widely crops. Pests ear grain, aphids wheat exerted greatest harmfulness experiment background with zero tillage.
