不同药剂对阜新地区松毛虫的防效比较
|
摘要
为筛选阜新地区松毛虫的最佳防治药剂,以2016年阜新地区3~4龄松毛虫为防治对象,对白僵菌粉、苏云金杆菌、25%灭幼脲3号悬浮剂3种无公害药剂的防治效果进行了比较研究。结果表明,几种药剂对松毛虫均显示了较为理想的防治效果,达到了86.7%以上,其中25%灭幼脲3号悬浮剂防效最佳,持效性强;苏云金杆菌的速效性较好,白僵菌粉具有一定的迟效性。2017年在阜新地区林间开展的松毛虫大面积防治试验显示,3种药剂总体防效以25%灭幼脲3号悬浮剂最优。大面积防治可有针对性地对药剂进行单一或合并使用。
In order to screen the best controlling agent of pine caterpillars in Fuxin area,the 3 rd to 4 th instar Dendrolimus punctatus in Fuxin area in 2016 was studied.The effects of Beauveria bassiana powder,Bacillus thuringiensis,25% Pollution-free pharmaceutical control effect were compared.Result shows that several agents show optimal control effect on Dendrolimus tabulaeformis and reach above 86.7%.In contrast,25% of the biocide 3 suspension have the optimal control effect and high efficiency.The quick-acting of Bacillus thuringiensisis optimal;Beauveria bassiana powder has a certain delay.In 2017,the large-scale prevention and control measures for pine dendrolimus in Fuxin area were additionally carried out.Combined with the occurrence of dendrolimus in Fuxin area,the overall efficacy of the three pesticides is still good and the optimal is 25%Chlorbenzuron 3 suspending agent.Large-scale prevention and treatment of these agents can be targeted for a single or combined use.
