我国是世界蔬菜水果生产第一大国,但是应用于果蔬上的杀菌剂苯并咪唑类、苯酰胺类、淄醇类、存在药效差,残留量大等问题,成为我国农产品出口的第一障碍,因此开发高效、低毒、无残留、无抗性的农用杀菌剂,是调整农业产业机构的迫切需要。本发明的植物杀菌剂的杀菌机理是当其喷洒到植物叶面上时,两个活性氯原子离解形成次氯酸或次氯酸根,次氯酸能够迅速渗入病原体内,通过氧化作用破坏病原菌的蛋白质结构和活性 China is the world’s largest producer of fruits and vegetables, but the benzimidazoles, benzamides and zeols, which are bactericides used on fruits and vegetables, have the problems of poor efficacy and large residues and become the first obstacle to the export of agricultural products in China Therefore, the development of efficient, low toxicity, no residue, no resistance to agricultural fungicides is an urgent need to adjust the agricultural industry institutions. The sterilizing mechanism of the plant fungicide of the present invention is that when it is sprayed on the foliage of plants, the two active chlorine atoms dissociate to form hypochlorous acid or hypochlorous acid. Hypochlorous acid can quickly penetrate the pathogen and destroy the pathogenic bacteria through oxidation Protein structure and activity
