玉米螟是我国玉米的主要害虫之一,以往玉米螟的药剂防治主要依靠六六六,由于有机氯农药的污染问题及其停产禁用,研究取代六六六的新杀虫剂已成为生产上急待解决的重要课题,通过1981～83年使用25种新农药进行室内测定、盆栽试验,田间小区试验和110亩大面积防治试验示范,筛选了优于六六六的杀虫剂,提高了经济效益和社会效益。现将防效高、药源广、经济、安全的杀虫双研究结果报道如下。 材料及方法 一,供试药剂 选用25％杀虫双水剂、6.5％杀虫双颗粒剂、2.5％杀虫双颗粒剂、5％杀虫双大粒剂、50％杀虫双高油剂、50％杀虫单原粉、6％六六六可湿性粉剂(对照药剂)。
Corn borer is one of the main maize pests in our country. In the past, the control of maize borer was mainly based on 666 pesticides. Due to the pollution of organochlorine pesticides and its discontinuation, the new insecticide to replace 666 has become a major production emergency The important topic to be solved was to screen the pesticides superior to BHC by using 25 kinds of new pesticides for laboratory determination, pot experiment, field plot experiment and large-scale prevention and control experiment in 110 mu from 1981 to 1983, which improved the economy Benefit and social benefit. Now anti-high efficiency, wide source of medicine, economy, safety insecticidal double research results are reported below. MATERIALS AND METHODS 1. The test agents were selected with 25% insecticidal double agent, 6.5% insecticidal double granules, 2.5% insecticidal double granules, 5% insecticidal double large granules, 50% insecticidal double high oil, 50% insecticidal single original powder, 6% six six six WP (control agent).
