35%辛硫磷微胶囊剂防治花生蛴螬试验及示范

2004年5～9月,在宿州、固镇田间小区试验和肥西县等大面积示范表明:35%辛硫磷微胶囊剂拌砂盖种防治花生蛴螬的效果比乳油剂型提高近2倍(或有效利用率提高近2倍);用微胶囊剂3000～4500g/hm2有效成分拌砂盖种,可以较好地控制全生育期花生蛴螬的危害,防治效果、保果率和增产效果分别在91.5%、75.0%和11.1%以上,有望使花生蛴螬防治方法实现重大变革,即由劳动强度大、不安全变为高效、安全、简便、省力。

Study on the Control of Peanut White Grubs

Two plot trials in the control of peanut white grubs with 35% phoxim CS were conducted in Suzhou and Guzhen county and More than 43 hectares of demonstration trials were conducted in Feixi county from May to September in 2004. The results showed that the control effect of 35% phoxim CS was double effect of phoxim EC, when they were used in their mixtures with sand to cover peanut seeds at sowing-time.3?000～4?500?g(ai)/hm 2 of 35% phoxim CS can effectively control the white grubs during the whole growing period of peanut.
