| 摘 要： | 以10％灭线磷GR为对照药剂,设98％棉隆MG 35、40、45 g/m2处理土壤防治黄瓜根结线虫.结果表明:98％棉隆MG 35、40、45 g/m2的3个处理,药后30 d土壤中2龄幼虫虫口减退率分别为89.45％、90.50％、92.05％,对照药剂10％灭线磷颗粒剂5 g/m2处理的虫口减退率为60.65％；药后90 d土壤中2龄幼虫虫口减退率分别为88.63％、89.73％、91.69％,对照药剂10％灭线磷5 g/m2处理的线虫虫口减退率为59.97％.98％棉隆MG各处理的防治效果分别为85.71％、88.80％、89.34％,而对照药剂为65.71％.表明98％棉隆MG可有效地控制黄瓜根结线虫的为害,有较好的推广应用价值.

| Abstract: | Taking 10% Ethoprophos granules as a control agents,using 98% Dazomet MG 35,40,45 g/m2 to treat soil on controlling cucumber root-knot nematode.The results showed that Dazomet 98% MG of 35,40,45 g/m2 was an excellent nematicide for controlling cucumber root knot nematode.The decline rate of J2 was 89.45%,90.50% and 92.05% by Dazomet 98% MG at 35,40,45 g/m2,respectively,while Ethoprophos was 60.65% after 30 days.The decline rate of J2 was 88.63%,89.73%,and 91.69% by Dazomet 98% MG at 35,40,45 g/m2,respectively while Ethoprophos was 59.97% after 90 days.The control efficacy was 85.71%,88.80% and 89.34% respectively.These results indicated that Dazomet 98% MG could be a prospective nematocide for cucumber root-knot nematodes control. |
