选用70%吡虫啉水分散粒剂、40%毒死蜱乳油、25%噻虫嗪水分散粒剂以及这3种农药的混配剂,分别稀释成5、10、20倍液,采用注干法对桉树枝瘿姬小蜂幼虫进行林间药效试验。试验表明,施药30 d后,相同浓度的不同药剂对桉树枝瘿姬小蜂幼虫... 选用70%吡虫啉水分散粒剂、40%毒死蜱乳油、25%噻虫嗪水分散粒剂以及这3种农药的混配剂,分别稀释成5、10、20倍液,采用注干法对桉树枝瘿姬小蜂幼虫进行林间药效试验。试验表明,施药30 d后,相同浓度的不同药剂对桉树枝瘿姬小蜂幼虫的校正死亡率则存在极显著差异。混配剂5倍液的防治效果最好,在30 d内对桉树枝瘿姬小蜂幼虫的校正死亡率为81.63%。施药后5~10 d,桉树枝瘿姬小蜂幼虫的死亡率增长速度最快;施药10 d后,死亡率的增长速度明显变缓。同一种药剂的浓度越高,对桉树枝瘿姬小蜂幼虫的致死时间越短。 展开更多

In this paper, the first generation and second generation of Chilo suppressalis Walker were conducted as the test objects to investigate control of a new pesticide(chlorantraniliprole) with preparation of chlorantraniliprole 20% SC,abamectin 1.8% EC and chlorpyrifos 40% EC to Chilo suppressalis Walker. The results showed that chlorantraniliprole 20% SC, abamectin 1.8% EC and chlorpyrifos40% EC had effective control to Chilo suppressalis Walker for its excellent control efficacy and long persistence period. Seedling protection efficacies were between84.2%-100%, 90.1% and 92.1%, and insecticidal efficacies were between 84.6%-100%,90.7% and 93.8% 36 days after application of chlorantraniliprole 20% SC in treatments with abamectin 1.8% EC and chlorpyrifos 40% EC for first generation Chilo suppressalis Walker control. The dead panicles were between 0.2%-1.4%, 0.8%and 0.7%, pest plant rate control in 0.4%-2.2%, 1.1% and 0.9%, and the rates of damaged rice plants were between 82.4%-97.6%, 90.2%-91.2% and 91.4%-92.8%,30 days after application of chlorantraniliprole 20% SC, abamectin 1.8% EC and chlorpyrifos 40% EC for the second generation Chilo suppressalis Walker control. It can effectively protect seedlings, protect spike, increase grain number and grain weight, which promoting the increase production income effect. The real estate increased by 9.7%-12.3%, 10.9% and 11.2% than water treatment(CK) with a very significant level, while the incomes were higher than 1 719.19-1 998.22, 1 956.52 and 2 057.83 yuan. 展开更多
