【摘要】 [目的]明确短稳杆菌在不同施用量下,对玉米黏虫的防治效果,对玉米安全性、施用方法等指标。[方法]采用田间茎叶喷雾,定期调查的方法进行试验。[结果]短稳杆菌对玉米黏虫有较高防效,且见效快。[结论]玉米田发生黏虫早期,可施用100亿孢子/mL短稳杆菌悬浮剂1200~2250mL/hm2进行防治,对水375L/hm2进行喷雾,一次性施药能防治此世代的黏虫,对玉米安全。更多还原

【Abstract】 [Aims] This study aims to confirm the control efficacy of Empedobacter brevis for controlling Mythimna separate(Walker) at different doses in corn field, and to clarify the safety on corn plants and application technology.[Methods] This experiment was carried out by stem and leaf spray, regular survey. [Results] The results showed that E.brevis has high control for M. separate with quick effect. [Conclusions] E. brevis 10 billion spore/m L SC could be used on controlling M. separate at early occurrence stage. The optimum dose is 1200-2250 mL/ha with water 375L/ha for spraying. The method could be effective for pest control, and be safe for corn plants.更多还原
