| 摘 要： | [目的]测定8种药剂对广西不同地区不同作物南方根结线虫的田间防效,并探讨其中高效药剂在不同地区、不同作物上药效的稳定性,为生产上推广应用提供依据.[方法]采用沟施、灌根的施药方式,测定噻唑磷、阿维菌素、厚壁孢轮枝菌、丁硫克百威、辛硫磷、线虫净、毒死蜱及甲维盐等8种药剂对广西不同地区香蕉、甘蔗、番茄、黄瓜、西瓜、烟草等作物南方根结线虫的田间防效.[结果]10%噻唑磷颗粒剂和0.2%甲维盐乳油对南方根结线虫的防效最好,平均防效分别达到86.16%和85.24%,且在不同地区、不同寄主作物上表现良好的稳定性;其次是1.8%阿维菌素乳油和5%丁硫克百威颗粒剂,防效分别为81.47%和77.26%;传统防治药剂50%辛硫磷乳油、5%线虫净颗粒剂、15%毒死蜱也有一定的杀线虫活性,防效在70%左右;生防菌剂5%厚壁孢轮枝菌粉剂的防效较差,平均为50.97%.[结论]噻唑磷、甲维盐、阿维菌素和J硫克百威对不同地区不同作物南方根结线虫均有较好的防效,4种药剂均可在生产上推广应用.

| Abstract: | 【Objective】The present study was conducted to test the field control efficacy of 8 kinds of pesticides on southern root-knot nematode in main crops of Guangxi， analyze efficacy stability of highly effective pesticides in different crops of varied regions， and provide references for production application. 【Method】By furrowing application and irrigating root， field control efficacies of such pesticides as lythidathion， avermectin， verticillium chlamydosporium， carbosulfan， phoxim， praziquantel premix， chlorpyrifos and emamectin benzoate on southern root-knot nematode in banana， sugarcane， tomatoes， cucumbers， melons and tobacco were determined. 【Result】10% nemathorin（GR） and 0.2% emamectin benzoate（EC）， which average control efficacy were 86.16 and 85.24%， respectively， showed the best control effect on southern root-knot nematode and strong stability in different host plants of different areas， followed by 1.8% avermectin oil （average control efficacy of 81.47%） and 5% carbosulfan （average control efficacy of 77.26%）. Traditional pesticides such as 50% phoxim， 5% praziquantel premix and 15% chlorpyrifos also displayed good performance in killing nematodes with control efficiency of around 70%， verticillium chlamydosporium showed the worst control efficacy of 50.97%. 【Conclusion】Four kinds of pesticides， viz.， lythidathion， emamectin benzoate， avermectin and carbosulfan had superior control efficacies on southern root-knot nematode in different crops of different regions， and could be applied and extended in production. |
