Effective test of 5% Zhelaijing GR against sugarcane borer

2005～2006年进行5%蔗来茎颗粒剂防治甘蔗螟虫大田药效试验,结果表明:5%蔗来茎对甘蔗螟虫具有良好的防治效果,其中以每667 m2施用5 kg防治甘蔗螟虫的效果最佳,药后60 d内的药效达到94.2%～96.0%,与对照药剂5%特丁磷颗粒剂相比差异显著,能够有效控制螟虫危害,建议在生产上推广应用。

From 2005 to 2006, the results of test in fields showed that 5% Pesticide Zhelaijing is better to control sugarcane borer.The result demonstrated that using 5% Pesticide Zhelaijing about 75 kg/hm2 had the best control effect than other treatments against sugarcane borer, it can be effective to control sugarcane borer about 94.2%-96.0% in 60 days, it suggest that using 5% Pesticide Zhelaijing about 75 kg/hm^2 is popularized on growing practice.
