多菌灵是一类高效广谱的苯并咪唑类杀菌剂,用于防治多种重要的植物病害。尽管其对子囊菌、多数半知菌和担子菌有效,但对卵菌、接合菌和少数半知菌却无效,如腐霉属真菌(Pythium spp.),链格孢属真菌(Alternaria spp.)和匍柄霉属真菌(Stemphylium spp.)。其抗药性机制主要是由于β-微管蛋白氨基酸的突变,导致蛋白质序列发生变 Carbendazim is a broad spectrum of benzimidazole fungicides for controlling a variety of important plant diseases. Although effective against Ascomycetes, Semiliutus and Basidiomycetes, they are ineffective against Oomycetes, Zygomycetes, and a few mycotoxins, such as Pythium spp., Alternaria spp. ) And Stemphylium spp. The drug resistance mechanism is mainly due to the mutation of β-tubulin amino acid, resulting in a change in the protein sequence
