近几年,氰戊菊酯(杀灭菊酯、速灭杀丁)和嗅氰菊酯一直是防治棉花害虫的“当家”农药品种,农民称之为“一扫光”。但是,由于长期使用单一品种,致使棉花害虫对它们产生了严重的抗药性。另外,这两种菊酯类杀虫剂对棉花红蜘蛛几乎无防治效果,又无内吸作用,价格较贵。久效磷也是一种防治棉花害虫的优良杀虫剂,对棉红蜘蛛有良好的防治效 In recent years, fenvalerate (fenvalerate, imazapyr) and azoxystrobin have been the “masters” of pesticide varieties that control cotton pests, which peasants call “swept away.” However, cotton pests have become severely resistant to them due to the long-term use of a single variety.
