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 rootknot nematode Meloidogyne incognita. Five nematicides and dosage were used to evaluate against rootknot nematode in combination with solarization, including dazomet 450 kg/hm2, 1,3dichloropropene+chlorpicrin 500 L/hm2, methamsodium 75 L/hm2, fosthiazate 30 kg/hm2 and methyl bromide 340 kg/hm2. Dazomet 450 kg/hm2 and fosthiazate 30 kg/hm2 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 rootknot nematode diseases in greenhouse vegetables in Northern China.
