黄瓜炭疽病是黄瓜主要病害之一。近几年随着塑料大棚的发展,由于棚内高温高湿,不通风,且多重茬,为害逐年严重。应用生物农药农抗120进行防治,效果达85.5％,优于代森锌M-45,接近多菌灵可湿粉。 1、试验材料和方法:1985年5月中旬,在吉林市郊九站的两座塑料大棚内,黄瓜叶片上相继发现褐色圆斑,病斑逐日扩大,病叶自下而上逐日增多。经室内培养分离、纯化、鉴 Cucumber anthracnose is one of the main diseases of cucumber. In recent years, with the development of plastic shed, due to the greenhouse high temperature and humidity, not ventilated, and multiple cropping, the damage year after year serious. Application of bio-pesticides and agricultural anti-120 control, the effect of 85.5%, better than dexamethasone M-45, close to carbendazim wettable powder. 1, Materials and Methods: In mid-May 1985, in two plastic greenhouses at nine stations in the outskirts of Jilin City, brown circular spots were successively found on the leaves of cucumber. The spots expanded day by day, and the diseased leaves increased day by day from bottom to top. The indoor culture separation, purification, Kam
