摘要
在河北省秦皇岛甘薯产区的甘薯茎线虫防效试验结果表明,施用维线克后甘薯茎线虫虫口平均减退率达89.44%,病情指数下降76.08%,甘薯平均增产率为607.25%。说明生化杀线虫剂维线克对甘薯茎线虫的防治具有应用前景。
Biochemical nematicide Weixianke was applied to control sweet potato stem nematode in Qinhuangdao, Hebei Province. The results showed that the average decrement of population of Ditylenchus distructor was 89.44%, average control efficiency on D. distructor was 76. 08%, the yield of sweet potato increased 607.25%. The studies indicated that Weixianke possesses the prospect in controlling nematode instead of chemical nematicide.
