Polyoxin
Bio-Strong broad-spectrum Bio-Control Bacterial and Fungus Disease for all crops
1: Polyoxin has strong bio-preventing & controlling rice sheath blight, strawberry gray mold, cucumber&melons downy mildew, powdery mildew, grape powdery mildew,downy mildew gray mold, apple spot and leaf rot, ring rot, pear black spot , tobacco brown spot, ginseng black spot etc
2: Mechanism of action: Polyoxin has good internal absorption and conduction effect. Its mechanism is to interfere with the biosynthesis of chitin in the pathogen cell wall, making it impossible for the pathogen cell wall to undergo biosynthesis, leading to pathogen death. After contact with the polyoxin, the bud tube and mycelium locally expand, rupture, and overflow the cell contents, which can not develop normally, leading to death. Therefore, it also has the effect of inhibiting pathogen spore production and disease spot expansion.
3: Brief: Polyoxin is produced by Streptomyces aureus fermentation, belonging to a broad spectrum of antibiotic fungicides, Low toxicity to non-target organism, widely used as a green and eco-friendly bactericide and fungicide for many crops.
