豇豆荚螟是豇豆上常见的重发害虫,其发生期长(6-10月),世代重叠,着卵分散,幼虫钻蛀花荚,一般药剂防治效果差,且虽经防治危害仍较重,7、8月份盛发期,一般田块豆荚被害率经防治后仍达50%以上,严重影响豇豆的产量和品质。同时由于菜农盲目滥用农药,豇豆豆荚上农药残留量高,严重威胁消费者身体健康。为筛选出有效防治豇豆荚螟的药剂,我站于2004年选择辛·唑等杀虫剂进行了田间药效比较试验,现将结果报告如下:
Cowpea pod borer is a common recurring pests on cowpea, its occurrence period is long (June-October), generation overlap, egg dispersal, larvae borer flower pods, the general effect of the agent is poor, and despite the prevention and treatment of the hazards are still heavier In July and August Shengfa period, the general field pea pod damage rate still reached more than 50% after the control, seriously affecting the yield and quality of cowpea. At the same time because of farmers blind abuse of pesticides, cowpea pods on pesticide residues, a serious threat to consumer health. In order to screen out the effective control of cowpea pods borer agents, I stand in 2004 selected insecticides such as symplectic azole field efficacy comparison test, the results are reported as follows:
