摘　　要：研究了万寿菊杀菌素Ⅰ对西瓜枯萎病菌、辣椒枯萎病菌和辣椒疫霉病菌的抑菌作用及对西瓜幼苗的影响。结果表明,万寿菊杀菌素Ⅰ能有效抑制西瓜枯萎病菌、辣椒枯萎病菌和辣椒疫霉病菌。在西瓜枯萎病的主要发病期苗期施用万寿菊杀菌素Ⅰ,能提高西瓜幼苗的POD和SOD活性,并维持CAT活性,有效减轻西瓜枯萎病菌对植株的毒害作用。Antifungal activity of marigold fungicide Ⅰ and its affection to watermelon seedling was studied.The results showed that marigold fungicide Ⅰ remarkable inhibited mycelial growth of Fusarium oxysporum f.sp.niveum,Fusarium oxysporum and Phytophthpra capsici Len..The marigold fungicide Ⅰ was applied at the main infection period of watermelon Fusarium wilt of seedling,it enhanced the enzymatic activity of superoxide dismutase（SOD）and peroxidase（POD）,maintained the CAT activity,and reduced the harm of crude toxin of FON to watermelon plant.
