摘　　要：不同药剂防治玉米穗期害虫研究结果表明,20%氯虫苯甲酰胺悬浮剂、40%氯虫·噻虫嗪水分散粒剂、0.4%氯虫苯甲酰胺颗粒剂对防治玉米穗期害虫效果较好,雌穗防效分别为83.8%、88.2%、77.9%,植株防效为84.1%、88.4%、78.3%;产量分别比清水对照增产15.0%、17.0%和13.7%,比药剂对照48%氯吡硫磷乳油增产4.9%、3.1%和1.9%。Effects of different agents on the control of corn ear pests were studied.Field trial results showed that the treat-ments of 20% Chlorantraniliprole SC,40% Chlorantraniliprole·Thiamethoxam WG and 0.4% Chlorantraniliprole Granu-lar had a good control effect on corn ear pests and the rate of controlling on corn ear was up to 77.9%-88.2%;the rate of controlling on corn plant was up to 78.3%-88.4%.And the corn yield could remarkably increase by every treatment, the 20% Chlorantraniliprole SC,40% Chlorantraniliprole·Thiamethoxam WG and 0.4% Chlorantraniliprole Granular in-creased yields by 15.0%,17.0% and 13.7% compared with water control and increased yields by 4.9%,3.1% and 1.9% compared with CK 48% Chlorpyrifos concentrate respectively.
