近年国内试验结果表明,杀灭菊酯及溴氰菊酯防治棉铃虫药效高,残效长,对人畜较安全,而对红蜘蛛药效很差。杀虫脒防治棉铃虫的药效优于滴滴涕,又能兼治红蜘蛛。两者混合使用有增效效应。减少单位面积用药量节省农药投资,扩大兼治对象,提高防治效果。Plapp1976年报道了杀虫脒与除虫菊素混用对棉铃虫增效达17倍。1977年A11报道了甲基对硫磷与二
In recent years, the results of domestic tests show that the control efficacy of pyrethroids and deltamethrin against bollworm is high, with long residual effects, safer to humans and animals, and less effective against spider mites. Chlordimeform control bollworm efficacy is better than DDT, but also both cure spider mite. Mixed use of both synergies. Reduce the dosage per unit area to save pesticide investment, expand the risk control target and improve the control effect. Plapp1976 reported that the avehidine amidst the moisture content of the growth rate of cotton growth benefit 17 times. 1977 A11 reported methyl parathion with two
