摘　　要：为明确硫酰氟熏蒸剂对黄瓜根结线虫病的防治效果。在2011—2012年间,采用田间对比试验的方法,进行了硫酰氟熏蒸剂对黄瓜根结线虫病的防效及对黄瓜产量影响的比较研究。结果表明:每平方米施药35.0g或50.0g,熏蒸10天且散气1周后定植黄瓜,可较好地控制黄瓜根结线虫危害。其中施药后50天防效分别为62.0%～61.5%、64.4%～70.2%,施药后90天防效分别为29.5%～45.3%、35.2%～50.9%,分别比对照增产17.5%～15.3%、25.3%～20.7%。生产上推荐35.0、50.0g/m2为较佳应用剂量。To investigate the control effect of profume fumigant against Meloidogyne spp. and yield of cucumbers, a field trial was conducted from 2011 to 2012. The results showed that lO-day fumigation （35 g/m2 or 50 g/m2） together with one-week ventilation before planting the cucumber could control the nematodes well. The control rates were 62.0%-61.5% and 64.4%-70.2% after 50 days of treatment, while those corresponding numbers became 29.5%-45.3% and 35.2%-50.9% after 90 days of treatment. Compared with the control, the yield of cucumbers was increased by 17.5%-15.3% and 25.3%-20.7% respectively. We recommend that the best applied dosage of profume fumigant should be 35 g/m2 or 50 g/m2 under field conditions.
