摘要
2年药效试验结果表明,在黑龙江省选用白僵菌150亿孢子/g球孢可湿性粉剂防治玉米螟,可明显提高越冬幼虫僵死率.药剂对环境无污染,对人和牲畜安全.施药宜选择春季解冻后,幼虫刚从秸秆中爬出寻找水源的关键时段,进行喷粉封垛防治.推荐剂量以18.75～25g制剂/m3为宜.
The result of two-year field trials showed that beauveria bassiana 15 billion spores/g WPcould significantly improve the mortality rate of overwintering larvae when chosen to control nubilais in Heilongjiang province. The product is safe for the environment as well as human and livestock. The best application timing was after spring thaw period when the larvae climb out from straw to find water with powder coating treatment. The recommended dose is 18.75-25g （formulated product）/m3.
