不同药剂药械防治马尾松毛虫效果及经济指标比较

Effects of Different Pesticide and Device Applications for Dendrolimus punctatus Control and Their Comparisons of Economic Indicators

通过使用不同药剂药械防治越冬代马尾松毛虫,结果表明:施药1 d后平均防治效果:烟剂为84.46%,水剂为89.96%,粉剂为58.44%;10 d后平均防治效果:烟剂为94.87%,水剂为95.48%,粉剂为94.16%。防治成本:水剂>烟剂>粉剂。综合防治效果、防治成本以及农药残留对林农养蚕、养蜂影响等因素,建议推广烟雾机烟剂防治技术(远离蚕桑的山区林区可推广森得保等粉剂防治)。

Different pesticides and devices were used to control the overwintering larvae of Dendrolimus punctatus.The results showed that the effects of the smoke agent,water agent and powder agent pesticide applications after 1 day were 84.46%,89.96% and 58.44% respectively,and 94.87%,95.48% and 94.16% respectively after 10 days.The cost of the pesticides was water agent smoke agent powder agent.Considering the control effect,cost and harmful influence of the pesticide residues on sericulture and apiculture,techniques for application of the smoke agent by sprayer were recommended（In areas far away from sericulture and apiculture,application of the powder agent may be promoted）.
