蚕豆赤斑病严重影响产量,是加速发展我省蚕豆生产的一大障碍。为了寻求经济有效的防治策略与方法,我们在对蚕豆叶部病害系统调查和损失率考察的基础上,在重病区采用多菌灵、托布津、井冈霉素等杀菌剂进行了药剂防治试验,取得了良好的效果。现总结如下: 一、材料和方法(一)小区试验:1982～1983年分别设25%多菌灵可湿性粉剂500倍和1000倍、50%托布津可湿性粉剂1000倍和1500倍、65%代森锌可湿性粉剂500倍、20%稻脚青可湿性粉剂250倍和500倍、5万单位井冈霉素500倍和 Vicia faba seriously affect the yield, is to accelerate the development of our province a major obstacle to the production of broad beans. In order to seek economical and effective control strategy and method, on the basis of investigating the system investigation and the loss rate of Vicia faba leaf disease, we carried out the medicament prevention and control experiment in the seriously ward using bactericide such as carbendazim, got a good result. Are summarized as follows: First, the material and methods (a) plot test: 1982 to 1983, respectively, 25% carbendazim WP 500 times and 1000 times, 50% Topaz WP 1000 times and 1500 times, 65% 500 times more dextrin zinc wettable powder, 250 times and 500 times more than 20%
