摘要
对香根草提取物虫道注射对桉蝙蝠蛾作用的初步试验,结果表明:在野外试验中香根草提取物对桉蝙蝠蛾毒杀作用较强。施药后3个月调查发现香根草枯叶乙醚热提剂的防效最高,为90.4%,对桉蝙蝠蛾有较强毒杀作用;施药后8个月调查,防效为100%。初步试验表明,香根草提取物每孔注射防治桉蝙蝠蛾的适宜用药量为5m l(1∶50),可望成为一种"绿色环保"的植物杀虫剂。
The tunnel injection experiment was made with 3 different distill liquid of vetivetin against Phassus sp, larvae. The result showed that the best control effect of vetivetin pick - up with ether reached 90.4% 3 month after the injection, the control effect of 3 different distill liquid of vetivetin reached all 100% respectively 8 month after the injection. The better dosage was 5 mL dilute liquid （1：50） per hole, Tunnel injection had certain control efficieney for Phassus sp. larvae.
