新型微生物杀螨剂LMFSSMJ-1防治柑橘红蜘蛛药效试验

Efficacy trials of a new microbial acaricide LMFSSMJ-1 against Panonychus citri

为验证微生物杀螨剂LMFSSMJ-1对柑橘红蜘蛛的防治效果,开展了室内卵活性抑制试验和田间药效试验。室内活性试验结果显示,LMFSSMJ-1可分散油悬浮剂400倍液对柑橘红蜘蛛卵具有良好的抑制作用,抑制率为(97.42±2.27)%。田间药效试验结果表明,LMFSSMJ-1可分散油悬浮剂具有良好的速效性和持效性。药后3 d,LMFSSMJ-1可分散油悬浮剂的防效在97%以上;药后21 d,LMFSSMJ-1可分散油悬浮剂的防效保持在80%以上。微生物杀螨剂LMFSSMJ-1具有田间应用的实际价值,是一款有效的生物农药。

In order to verify the control effects of the new microbial acaricide LMFSSMJ-1 on Panonychus citri,the indoor egg inhibition experiments and efficacy trials were carried out.The indoor inhibition experiments showed that LMFSSMJ-1 OD had good inhibitory effects on Panonychus citri,with the inhibitory rate of(97.42±2.27)%.The efficacy trials showed that LMFSSMJ-1 OD had good quick and persistent effect.At the 3rd day after application,the control effects of LMFSSMJ-1 OD were more than 97%.At the 21st day,the control effects of LMFSSMJ-1 OD were over 80%.Microbial acaricide LMFSSMJ-1 had practical value in field application and could be used as an effective biopesticide.
