对大豆蚜虫常用有机氯及有机磷酸酯类杀虫剂,近年来抗药性日益严重,如果提高药液浓度和增加喷药次数又会遭致杀伤天敌及污染环境。为此,我们从1979年开始用呋喃丹和涕灭威进行防治大豆蚜虫试验。在每亩用5％呋喃丹颗粒剂5斤;每亩用3％呋喃丹微粒剂5斤;每亩用10％涕灭威3斤随种沟施。在蚜虫盛发期调查,防治效果分别为94.7％、94.4％、100％。在大豆整个生育期均为有效控制期,效果高于乐果,施用方法简便,对后作物无影响。
Common organic chlorine and organophosphate insecticides to soybean aphids have become more and more serious in recent years. If increasing the concentration of the liquid medicine and increasing the number of spraying, it will cause natural enemies and pollute the environment. To this end, we started from 1979 with carbofuran and aldicarb control soybean aphids. 5% carbofuran granules per mu with 5 kg; 3% carbofuran granules per acre with 5 pounds; 3 acres with 10% aldicarb per acre with seed ditch facilities. In the aphrodisiac investigation, the control effect was 94.7%, 94.4% and 100% respectively. In the whole growth period of soybean are effective control period, the effect is higher than the dimethoate, the application method is simple, no effect on the after crop.
