摘要
通过不同浓度的噻虫啉微胶囊粉剂防治松褐天牛药效试验,结果表明,噻虫啉微胶囊粉剂对松褐天牛有很好的防治效果。0.5%、1%、2%噻虫啉微胶囊粉剂(7.5 kg/hm2)防治松褐天牛,药后35 d效果分别为64.26%、86.60%、86.94%,1%噻虫啉微胶囊粉剂对松褐天牛防效远高于0.5%噻虫啉微胶囊粉剂的防治效果,与2%噻虫啉微胶囊粉剂的防治效果差异不显著,建议用1%噻虫啉微胶囊粉剂7.5 kg/hm2防治松褐天牛。
The efficacy test was made by varying the concentration of thiacloprid microcapsule powder against Monochamus alternatus, the results showed that thiacloprid microcapsule powder has a good control effect on. 0.5%, 1%, 2% thiacloprid microcapsule powder （7.5 kg/hm^2） controlling M. alternatus, after 35 d of treatment the effect was 64.26%, 86.60%, 86.94%, respectively; control effect of 1% thiacloprid microcapsule powder was higher than that of 0.5%, control effect difference and 2% thiacloprid microcapsule powder was not significant, the prevention was that control M. alternatus with 1% thiacloprid microcapsule powder 7.5 kg/hm^2.
