Polyoxin

Polyoxin, a metabolite produced by Streptomyces aureofaciens, is a broad-spectrum antibiotic fungicide with good systemic and translocation properties. Its mechanism of action is to interfere with the biosynthesis of chitin in the cell walls of pathogens, preventing the cell walls from undergoing biosynthesis and leading to the death of the pathogen. After the germ tubes and hyphae come into contact with the agent, they locally swell, rupture, and release intracellular contents, unable to develop normally and eventually die. Therefore, it also has the effect of inhibiting spore production and the expansion of disease spots of pathogens.

Due to its high efficiency, low toxicity, and no environmental pollution, polyoxin is widely used in the prevention and control of important diseases in food crops, special crops, fruits, and vegetables. Polyoxin is a class of antibiotics with very similar structures, consisting of a mixture of 14 different homologues from A to N. The functions of each main component are different. Therefore, in agricultural applications, it is mainly divided into two categories: one category mainly consists of components a and b, and is mainly used to control apple scab, ring rot, pear black spot disease, grape gray mold, powdery mildew and downy mildew of strawberries, cucumbers, melons, black spot disease of ginseng, and tobacco brown spot disease, among more than ten crop diseases. The other category mainly consists of components d, e, and f, and is mainly used to control rice sheath blight. function; role; effect; influence
