多抗霉素

多抗霉素用途

【用途1】
广谱性抗菌素类杀菌剂，具有内吸传导作用。其作用机制是干扰细胞壁壳多糖的生物合成。以壳多糖为基质而构成细胞壁的子囊菌纲、担子菌纲和半知菌纲的一些真菌，芽管和菌丝体接触药剂后会局部膨大、破裂、溢出细胞内含物，导致死亡。主要用于防治小麦白粉病，人参黑斑病，烟草赤星病，黄瓜霜霉病，瓜类枯萎病，水稻纹枯病，苹果斑点落叶病，草莓及葡萄灰霉病，林木枯鞘病等多种真菌病害。如用宝丽安10%可湿性粉剂1000～2000倍液可防治小麦白粉病和水稻纹枯病，若用量15～22.5g/100m²在花开期开始喷药，可防治番茄、草莓等作物的灰霉病，以后隔7d喷1次，共3～4次。对苹果斑点落叶病，在苹果春梢生长期、发病盛期，用50～100mg/L多抗霉素溶液喷雾。
