Abstract

The invention relates to a bactericidal composition containing pyrimidine nucleoside antibiotic and hymexazol. The bactericidal composition comprises the following active ingredients: pyrimidine nucleoside antibiotic and hymexazol according to the weight ratio of (32:3) to (1:48). The bactericidal composition disclosed by the invention is good in control effect and low in cost, and the resistance of pathogenic bacteria can be delayed.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a bactericidal composition containing pyrimidine nucleoside antibiotics and hymexazol and an application thereof. Background technique [0002] Pyrimidine nucleoside antibiotics, also known as Nongkang 120, are fermented and extracted from Streptomyces hygroscopicus var. Beijing. They are broad-spectrum fungicides and have dual functions of protection and treatment. The drug has obvious inhibitory effect on the growth of mycelia, causing the growth of mycelium to deform, and the internal protoplasm to solidify, which hinders the synthesis of pathogenic protein and leads to the death of pathogenic bacteria. It can control various fungal diseases such as powdery mildew, anthracnose, blight, and black spot on fruit trees, vegetables, and food crops. [0003] Hymexazol belongs to the oxazole fungicides, which are systemic and conductive. After the drug enters the soi...
