摘要 选用93% 1，3-二氯丙烯乳油（EC）、62% 1，3-二氯丙烯胶囊、42%威百亩水剂（AS）、98%棉隆微粒剂（MG）、99%硫酰氟原药（TC）、93% 1，3-二氯丙烯EC +98%棉隆MG、93% 1，3-二氯丙烯EC+42%威百亩AS防治黄瓜根结线虫，以98%溴甲烷为对照。结果表明：不同熏蒸剂对根结线虫均有良好的防治效果。各熏蒸处理黄瓜产量均显著高于不施药对照，以50 g m-2 98%溴甲烷处理产量最高，其次为9 g m-2 93% 1，3-D EC+25 g m-2 98%棉隆MG、9 g m-2 93% 1，3-D EC+21 g m-2 42%威百亩AS|混用的溴甲烷替代品与溴甲烷相比，经济效益更好。9～18 g m-2 93% 1，3-D EC、9～18 g m-2 62% 1，3-D胶囊和25～50 g m-2 99%硫酰氟TC处理也有很好的增产效果和良好的经济效益。
Abstract：Several fumigants，93% 1，3-dichloropropene EC，62% 1，3-dichloropropene capsule，42% metham sodium AS，98% dazomet MG，99% sulfuryl fluoride TC，93% 1，3-D EC+98% dazomet MG，and 93% 1，3-D EC+42% metham sodium AS，were used to control cucumber root-knot nematodes．98% Methyl bromide was used as control．The results showed that all fumigant treatments had good efficacy against root-knot nematodes．The cucumber yield from all fumigant treatments was higher than that of untreated control．The yield obtained by treatments of 50 g m-2 98% Methyl bromide，9 g m-2 93% 1，3-D EC+25 g m-2 98% dazomet MG and 9 g m-2 93% 1，3-D EC+21 g m-2 42% methm sodium AS were the higher than the control．Good yield and economic benefits can also be achieved，when cucumber is treated with fumigants 9～18 g m-2 1，3-D EC，1，3-D capsule and 25～50 g m-2 sulfuryl fluoride TC.
