【摘要】 通过田间小区试验比较了70%噻虫嗪种子处理水分散粒剂WDG(锐胜)、60%吡虫啉悬浮种衣剂FS(高巧)、3%辛硫磷颗粒剂GR、40%毒死蜱辛硫磷乳油EC、15%阿维毒死蜱乳油EC、15%阿维辛硫磷乳油EC 6种杀虫剂对大豆田蛴螬的防治效果及大豆增产的效果。结果表明,药剂处理后,对大豆安全,未出现药害;70%噻虫嗪WDG对蛴螬的防效达79.41%,大豆增产率为45.43%;60%吡虫啉FS对蛴螬的防效为76.47%,大豆增产率为48.03%;70%噻虫嗪WDG和60%吡虫啉FS的试验效果显著高于防效和增产率分别在54.41%~69.12%、22.09%~34.56%之间的其他4种药剂;6种药剂对大豆苗期和成熟期大豆植株的株高、鲜重、单株豆荚数等指标均未产生显著影响。更多还原

【Abstract】 In order to scientifically and effectively control white grub in soybean field, we set a series of field experiment using application method of seed dressing and soil mixed with 6 different pesticides,including 70% thiamethoxam WDG(Cruiser), 60%imidacloprid FS, 3%phoxim GR, 40%chlorpyrifos +phoxim EC, 15% abamectin + Chlorpyrifos EC, and 15% abamectin + phoxim EC. The results showed,the 6 pesticides used during sowing time were safe and had no effects on emergence rate of soybean seedlings; the control efficiency of 70% thiamethoxam WDG and 60%imidacloprid FS were 79.41% and 76.47% respectively,and soybean yield increase rate was 45.43% and 48.03% respectively; significantly higher than other 4 pesticides. The results indicated, the 6 pesticides had no significant effects on the plant height, fresh weight and single seedpod number of soybean plants in soybean seedling stage and mature stage.更多还原
