本试验通过做 2 0 %杀蝗绿僵菌油剂 3个不同剂量与 75 %马拉硫磷油剂进行防治东亚飞蝗田间药效对比试验 ,结果表明 :2 0 %杀蝗绿僵菌油剂防治东亚飞蝗 ,在第 9天后表现出明显的防治效果 ,3种剂量防治效果均达 75 %以上 ,第 13天后均达 93%以上 ,其中每hm2 用 375ml施药量防治效果达 95 .5 %。从而证明2 0 %杀蝗绿僵菌油剂是防治东亚飞蝗一种较好的生物农药 ,每hm2 用 375ml的施药量是值得推广应用的一种剂量。
This experiment by doing 20% kill Metarhizium anisopliae oil three different doses and 75% malathion oil agent against East Asian locust field efficacy comparison test showed that: 20% Metarhizium locust The prevention and treatment of Locusta migratoria manilensis showed obvious control effect after 9 days. The control effect of three dosages reached more than 75% and reached 93% after the 13th day, respectively. The control effect of 375 ml dose per hm2 was 95%. 5%. It was proved that 20% of Metarhizium anisopliae locust oil agent is a better biological pesticide for controlling Locusta migratoriae, and a dose of 375ml per hm2 is worth popularizing and applying.
