以铁灭克为对照药剂，研究了米乐尔、敌敌畏及其复合施用防治黄瓜根结线虫病的效果。结果表明：敌敌畏的速效性最好，施药９ｄ后，对病情有明显的控制作用，较清水对照差异达极显著水平，但持效性较差；米乐尔的速效性不如敌敌畏，持效性明显好于敌敌畏，但不如对照药剂铁灭克；敌敌畏和米乐尔复合施用后，明显提高了药效，其速效性与敌敌畏相近，持效性明显优于米乐尔，施药２５ｄ后防效与米乐尔差异达显著水平，与对照药剂铁灭克相同。
Taking fermenter as control agent, the effects of mitral, dichlorvos and their combined application on cucumber root-knot nematode disease were studied. The results showed that dichlorvos had the best fast-acting effect. After 9 days, the dichlorvos had the most obvious effect on the disease. The difference was significant compared with the control It is obviously better than dichlorvos but not as good as that of the control agent. After the combination of dichlorvos and micelles, the efficacy is obviously improved. The effectiveness is better than that of dichlorvos. The difference between the control effect and the Michel reached a significant level, which was the same as that of the control agent.
