摘要
Abstract
A field experiment was conducted to determine the efficiency of 0.4% chlorantraniliprole granules to control rice striped stem borer. The result showed that the control efficiency was high when using 600 g, 700 g, 800 g/667m^2 of 0.4% chlorantraniliprole granules. Using the insecticide 10 days before the peak occurrence of the second instar larvae of rice stem borer, the control efficiency 21 days, 30 days and 40 days after application was 86.18%-100%, 84.62%-96.41%, and 82.28%-92.86%, respectively. And the spraying of 700-800 g/667m^2 resulted in the best efficiency, in which both the speed and the lasting time were far better than the control insecticides. Well-distributed spraying the insecticides 10 kg mixed fine soil grains per 667 m^2 before the peak incidence of the second instars of rice stem borer was the best option in extension.关键词
