根据拟除菊酯—杀虫脒合剂对棉铃虫等多种夜蛾科幼虫具有增效作用特性(7,14),我们通过室内触杀毒力试验和两个棉区一、二年田间药效试验,初步发现杀灭菊酯—杀虫脒盐酸盐(1:5—10)合剂对棉蚜也具有明显的增效效果。通过合剂的应用,杀灭菊酯高效控制棉蚜的经济施药剂量可较大幅度降低,这对促进棉花生产、降低进成本具有现实意义。现初步报导于下。
According to the synergistic effect of insecticide-amidinate and other insecticides against Helicoverpa armigera larvae (7,14), we tested the indoor exposure to virulence test and the field efficacy of one or two years in two cotton fields Test, initially found that fenvalerate - chlordimeform hydrochloride (1: 5-10) mixture of aphids also have a significant synergistic effect. Through the application of the mixture, the economic application dosage of the fenvalerate control cotton aphid can be greatly reduced, which is of practical significance to promote the cotton production and reduce the cost. Now reported initially under.
