- Abstract
In this paper, the first generation and second generation of Chilo suppresses Walker were conducted as the test objects to investigate control of a new pesticide (chlorantraniliprole) with preparation of chlorantraniliprole 20% SC, abamectin 1.8% EC and chlorpyrifos 40% EC to Chilo suppressalis Walker. The results showed that chlorantraniliprole 20% SC, abamectin 1.8% EC and chlorpyrifos 40% EC had effective control to Chilo suppressalis Walker for its excellent control efficacy and long persistence period. Seedling protection efficacies were between 84.2%-100%, 90.1% and 92.1%, and insecticidal efficacies were between 84.6%-100%, 90.7% and 93.8% 36 days after application of chlorantraniliprole 20% SC in treatments with abamectin 1.8% EC and chlorpyrifos 40% EC for first generation Chilo suppressalis Walker control. The dead panicles were between 0.2%-1.4%, 0.8% and 0.7%, pest plant rate control in 0.4%-2.2%, 1.1% and 0.9%, and the rates of damaged rice plants were between 82.4%-97.6%, 90.2%-91.2% and 91.4%-92.8%, 30 days after application of chlorantraniliprole 20% SC, abamectin 1.8% EC and chlorpyrifos 40% EC for the second generation Chilo suppressalis Walker control. It can effectively protect seedlings, protect spike, increase grain number and grain weight, which promoting the increase production income effect. The real estate increased by 9.7%-12.3%, 10.9% and 11.2% than water treatment (CK) with a very significant level, while the incomes were higher than 1 719.19-1 998.22, 1 956.52 and 2 057.83 yuan.
