菌蝇是为害平菇等多种食用菌的主要虫害,近年来愈来愈重,不仅降低食用菌产量,还使品质变劣。应用化学药剂防治,对食菌有不同程度的药害。我们自1990-1991年在平菇上试用烟草汁防治菌蝇,防效达96％以上,此法简便易行、成本低,安全无毒。其方法是:取新鲜老烟叶捣烂榨汁与半量的湿润油丝烟粪混合加少量清水继续捣烂并充分搅拌,置阴湿处封闭浸泡12小时,然后取汁,兑3倍清水。喷在菌床及其周围和玻璃门窗
Mushroom damage is the main fungus Mushrooms and other edible fungi the main pests, more and more weight in recent years, not only reduce the yield of edible fungi, but also to make the quality worse. Application of chemical control, the bacteria have different levels of phytotoxicity. Since 1990-1991, we experimented on the use of tobacco juice on mushrooms to prevent and control the fly flies. The anti-bacterial effect was over 96%. This method is simple and easy, low cost, safe and nontoxic. The method is: take fresh old tobacco leaf smashed juice and half the amount of wet oil silk manure mixed with a small amount of water continue to mash and stir, set the closed wet soak for 12 hours, and then juice, against 3 times the water. Spray in the bacteria bed and its surrounding and glass doors and windows
