为进一步谋求解决危害小麦、玉米、棉花等作物的棉铃虫、蚜虫、粘虫、玉米螟等害虫的有效药剂,2002年永年县技术推广中心从河南省开封市丰田化工厂,引进低毒高效20％杀得快乳油(20％氯辛乳油)进行了大面积试验示范后表明:该药剂对棉铃虫、蚜虫、玉米螟等害虫,不仅具有触杀胃毒作用、击倒速度快、效果显著等特点,而且农药残留量低于国家规定标准。据调查:用于除治棉铃虫、蚜虫3分钟即可见效,5分钟即可击倒,总有效率为98.6％以上。主要使用方法:用于防治棉铃虫,不同代数,当百株幼虫20～
In order to further seek effective solutions to the insecticides such as cotton bollworm, aphid, armyworm and corn borer that endanger the crops such as wheat, corn and cotton, Yongnian County Technology Promotion Center in 2002 from Toyota Chemical Factory in Kaifeng City, Henan Province, the introduction of low toxicity and efficient 20 % Kill fast EC (20% chlorine symplectic EC) carried out a large area demonstration shows that: the agent of cotton bollworm, aphids, corn borer and other pests, not only has the role of contact poisoning stomach poisoning, knockdown speed, significant effect and so on , But pesticide residues below the national standard. According to the survey: For the exception of cotton bollworm, aphids can be effective for 3 minutes, 5 minutes to knock down, the total efficiency of 98.6% or more. The main method of use: for the control of cotton bollworm, different algebra, when one hundred larvae 20 ~
