摘要
以10%灭线磷GR为对照药剂,设98%棉隆MG 35、40、45g/m2处理土壤防治黄瓜根结线虫。结果表明:98%棉隆MG 35、40、45g/m2的3个处理,药后30d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5g/m2处理的虫口减退率为60.65%;药后90d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5g/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。
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.
