对２９个烟草品种资源材料进行根结线虫抗性鉴定，并对感病和不感病的各品种的产量、收益、化学成分进行了比较，同时做了涕灭威对烟草根结线虫病的药效试验，结果表明，Ｋ３５８、ＲＧ８、ＲＧ２２、红大（卫）为高抗品种，ＮＣ７２９、Ｋ３２６、Ｒｅａｍｓ７１３、红花大金元等为抗病品种；根结线虫病对烟叶产量质量有一定影响；用５％涕灭威每亩１ｋｇ对８１个品种进行防治试验，结果表明平均防效达８６％，并对９０％以上品种有效。 Root-knot nematode resistance was evaluated on 29 tobacco cultivars, and the yield, yield and chemical composition of the susceptible and non-susceptible cultivars were compared. At the same time, aldicarb was tested against tobacco root-knot nematodes The results showed that K358, RG8, RG22 and Hongda were high resistance varieties, such as NC729, K326, Reams713 and Hongda Daijin yuan, etc. The root knot nematode disease had some effects on the yield and quality of tobacco The control experiment of 81 varieties with 1 kg of aldicarb 5% showed that the average control efficiency reached 86% and was more than 90% effective.
