摘要
田间系统调查结果表明,根结线虫在大棚黄瓜的整个生长季节可以完成3个世代,世代重叠明显。室内和田间药剂防治试验表明,1.8%集琦虫螨克乳油、10%克线丹颗粒剂对温室黄瓜根结线虫病具有良好的防治效果,但仅在移栽前施用1次不能有效控制根结线虫的危害,次年2月下旬仍需再次防治。移栽前施用克线丹60 kg/hm2,次年2月下旬施用集琦虫螨克10 000 mL/hm2的防治效果较好。
Experiments on the epidemical pattern and chemical control of root - knot nematode ： Melaiogyme incognito Chitwood were conducted in laboratory and protected field in Luoyang of Henan Province. The results showed that the nematode completes three generations in a growing season and generation overlapping occurred obviously. The controlling efficiency of insecticides such as cadusafos （ 10 G） and abamectin （1.8 Ec） were better than ethophos （ 10 G） , which is common used. It is suitable for cadusafos to be applied by means of soil - treated before cucumber transplanted, and for abamectin to be applied in the last ten - days in February.
