稻纵卷叶螟是玉林地区水稻主要害虫之一,近几年来普遍发生为害,局部严重,甚至成灾。目前供应的药剂防治该害虫的效果不够理想,已发生抗药性,如6%六六六对高龄幼虫毒杀效果降低,对成虫无效;甲六粉毒杀成虫也无效。为此,我们采用几种新农药于去年早、晚造对该害虫进行田间防治试验。 Rice leafroller is one of the main rice pests in Yulin area, which has been widely reported to have been harmed in recent years, causing serious or even disaster. At present, the effect of the pesticide for controlling the pest is not satisfactory, and resistance has already occurred. For example, 6% of the 666 pairs of young larvae reduce the poisoning effect and are ineffective to adults; To this end, we used several new pesticides to make pest control experiments in the field early and late last year.
