１９９５～１９９６年，笔者应用涕灭威颗粒剂对棉田中主要害虫进行大田试验示范。结果表明，播种时１ｈｍ２施５％涕灭威颗粒剂１５ｋｇ与棉籽同沟相伴撒下，可有效控制小地老虎、棉蚜的危害，对害虫天敌无明显影响。在栽培措施与其它管理措施相同的情况下，应用涕灭威颗粒剂可增产１２．７％。
From 1995 to 1996, the author applied aldicarb granules to field experiments on major pests in cotton fields. The results showed that 15 kg of 5% aldicarb 1hm2 sowing seedlings were planted in the same ditch with cottonseed, which could effectively control the damage of the small tiger and the cotton aphid and had no obvious effect on the natural enemies of pests. In the case of cultivation measures and other management measures under the same circumstances, the application of aldicarb granules can increase 12.7%.
