不同药剂对人工油松林大蚜的防治分析

Analysis on the Control of Aphids in Artificial Pinus tabulaeformisForests with Different Chemicals

以云南省曲靖市师宗县彩云镇油松人工林为试验材料,设置了6个不同的杀虫剂处理,比较了不同药剂对人工油松林大蚜的防治效果。结果表明:10%吡虫啉可湿性粉剂1500倍液+温水完全溶解的2‰洗衣粉、10%吡虫啉可湿性粉剂1500倍液+4.5%高效氯氰菊酯微乳剂2000倍液+温水完全溶解的2‰洗衣粉、10%吡虫啉可湿性粉剂1500倍液+45%毒死蜱乳油1500倍液+温水完全溶解的2‰洗衣粉3个处理油松人工林蚜虫防治效果较好,在施药后10 d防治效果仍然可以超过97%。综合考虑多个因素,认为采用10%吡虫啉可湿性粉剂1500倍液+温水完全溶解的2‰洗衣粉防治人工林油松大蚜较为理想。

This paper takes the Pinus tabulaeformis plantation in Caiyun Town,Shizong County,Qujing City,Yunnan Province as the experimental material,and sets up 6 different insecticide treatments to compare the control effects of different pesticides on aphids in the artificial Pinus tabulaeformis forest.The results showed that the three treatments of 10%imidacloprid wettable powder 1500 times solution+2‰washing powder completely dissolved in warm water,10%imidacloprid wettable powder 1500 times solution+4.5%high-efficiency cypermethrin microemulsion 2000 times solution+2‰washing powder completely dissolved in warm water and 10%imidacloprid wettable powder 1500 times solution+45%chlorpyrifos emulsion 1500 times solution+2‰washing powder completely dissolved in warm water had good control effects on aphids in Pinus tabulaeformis plantations.The control effect can still exceed 97%after 10 d of application.Taking into account multiple factors,it is believed that the use of 10%imidacloprid wettable powder 1500 times liquid and 2‰laundry detergent completely dissolved in warm water is more ideal for controlling the Pinus tabulaeformis forests.
