摘　　要：为了筛选安全、高效、实用的化学防治技术,对国内外生产的5种杀线虫剂(棉隆、1,3-二氯丙烯.氯化苦、威百亩、噻唑磷、溴甲烷)土壤处理结合阳光消毒防治番茄根结线虫的效果进行了评价。结果表明,使用98%棉隆微粒剂450 kg/hm2或10%噻唑磷颗粒剂30 kg/hm2防治番茄根结线虫(Meloidogyne incognita),结合夏季高温进行阳光消毒,能有效地降低番茄根结线虫的数量,减轻根结线虫的危害程度,节省农户的生产成本,提高番茄的产量和农户的经济效益,是夏季防治番茄根结线虫的有效措施。In this study, different soil nematicide treatments in combination with solarization were carried out to evaluate their effects on managing the rootknot nematode Meloidogyne incognita. Five nematicides and dosage were used to evaluate against rootknot nematode in combination with solarization, including dazomet 450 kg/hm2, 1,3dichloropropene＋chlorpicrin 500 L/hm2, methamsodium 75 L/hm2, fosthiazate 30 kg/hm2 and methyl bromide 340 kg/hm2. Dazomet 450 kg/hm2 and fosthiazate 30 kg/hm2 provided the most effective results. It gave maximal decrease in juveniles of root knot nematode, increase of plant output and economic benefit and minimal damage by diseases. It is a suitable method for the management of tomato rootknot nematode diseases in greenhouse vegetables in Northern China.
