The Comprehensive Prevention and Control Technology of Early Main Diseases and Insect Pests on Maize in Liaoning
摘要
Abstract
Aim at the situation of default in comprehensive prevention and control technology of main diseases and insect pests,and difficulty in field operation in corn production of Liaoning province. Taking maize top rot,maize borer and gray leaf spot as the objects of prevention and treatment,We preliminarily researched the comprehensive prevention and control technology of these diseases with chemicals in sowing and whorl stage in the west of Liaoning province in 2014. The results showed that treating with 7. 5% Carbofuran and tebucon-azole floating suspeusion seed coating agent was the best way to control corn top rot,with 90. 66% ~ 100%control efficacy;the chemical prevention using machine spray in corn whorl stage was taken,the control effi-cacy of corn borer was up to 87. 28% ,the disease grade and disease index of gray leaf spot was down to 0. 9~ 2. 52 and 46. 79% ~ 56. 24% . These measures reduced the effects of diseases and insect pests on corn yield,and the loss of corn yield was reduced by 3. 91% ~ 10. 09% .关键词
