苹果斑点落叶病(Alternaria mali Roberts)是近年来国内外普遍发生而为害严重的一种新病害。自1988年以来,通过新农药筛选,从10余种新农药中筛选出一种防效与法国产扑海因相当的新农药——代森锰锌。经田间药效试验和较大面积的生产防治示范证明,代森锰锌为防治苹果斑点落叶病较为理想的药剂品种之一,且可兼治苹果轮纹病等病害。70％可湿性代森锰锌生产使用以稀释500～800倍为宜,可以与常规农药波尔多液等交替使用。1989年在胶州市沙河园林场进行较大面积防治示范,年中喷布800倍代森锰锌3
Alternaria mali Roberts is a new disease which is serious and harmful in China and abroad. Since 1988, through screening of new pesticides, more than 10 kinds of new pesticides have been screened for a new pesticide, mancozeb, which has the same efficacy as the French-made lovastatin. After the field efficacy test and a large area demonstration of prevention and control of production, mancozeb is one of the more ideal drug varieties for preventing and curing apple leaf spot deciduous diseases, and can simultaneously cure diseases such as apple ring rot disease. 70% wettability Mancozeb used to dilute 500 to 800 times is appropriate, can be used with conventional pesticide Bordeaux mixture alternately. In 1989 Jiaozhou City Shahe garden far large area prevention and control demonstration, spraying 800 times during the year mancozeb 3
