Analysis on the Control of Aphids in Artificial Pinus tabulaeformis Forests with Different Chemicals
This paper takes the Pinus tabulaeformis plantation in Caiyun Town,Shizong County,Qujing City,Yun-nan 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 cyper-methrin 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 ‰ wash-ing powder completely dissolved in warm water had good control effects on aphids in Pinus tabulaeformis planta-tions.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 com-pletely dissolved in warm water is more ideal for controlling the Pinus tabulaeformis forests.
