设施栽培年限的延长、面积的扩大导致根结线虫的危害日益严重，同时又加重了枯萎病、根腐病、疫病等其他土传病害的发生。试验通过威百亩在黄瓜、草莓和百合上的应用，结果表明：42%威百亩水剂25 kg/667m2或30 kg/667m2，采用灌溉施药法或开沟施药熏蒸法，对几种作物根结线虫病及其他土传病害的控制作用明显，不同作物的防治效果均在92%以上，且增产明显。施用一次，黄瓜上控制根结线虫病可达1a以上。
設施栽培年限的延長、麵積的擴大導緻根結線蟲的危害日益嚴重，同時又加重瞭枯萎病、根腐病、疫病等其他土傳病害的髮生。試驗通過威百畝在黃瓜、草莓和百閤上的應用，結果錶明：42%威百畝水劑25 kg/667m2或30 kg/667m2，採用灌溉施藥法或開溝施藥熏蒸法，對幾種作物根結線蟲病及其他土傳病害的控製作用明顯，不同作物的防治效果均在92%以上，且增產明顯。施用一次，黃瓜上控製根結線蟲病可達1a以上。

For the years extending and the area expanding of protected cultivation, the damage of root-knot nematode becomes more and more serious, while the occurrence of the other soil-born diseases such as wilt, root rot and blight also increased. The experiments of applying metham-sodium to cucumber, strawberry and bulbus lilii were conducted. The results showed that no matter with irrigation method or furrowing fumigating method, 375 kg/hm2 or 450 kg/hm2 of 42%metham-sodium water agent all had significant control effect on the root-knot nematode and the other soil-born diseases for several crops, and the control effect of different crops all reached over 92%, while the yield-increasing effect was also obvious. Applied metham-sodium once, the control effect on the root-knot nematode for cucumber can last for more than a year.
