On July 24th, 20% Chunreimycin water-dispersible granules applied by Shandong Rushan Hanwei Biotechnology Co., Ltd. were approved for registration. The registered crops and control objects were peach tree brown spot perforation, and the recommended drug concentration was 66.7-100. Mg/kg (equivalent to 2,000-3,000 times equivalent to commercial product), the application method is stem and leaf spray. This is the first time that China has approved the registration of chunleimycin on peach trees.

Previously, the registered crops and control targets for the approval of chunleimycin (including its compounding agents) in China include rice blast, rice smut, sheath blight, cucumber blight, downy mildew, anthracnose, bacterial angular spot, Watermelon bacterial angular leaf spot, tomato leaf mold, cabbage black rot, soft rot, pepper anthracnose, potato black shank, tobacco brown spot disease, wildfire disease, coffee tree bacterial angular spot disease, citrus tree canker disease, Litchi tree Phytophthora and ornamental chrysanthemum bacterial angular leaf spot.

Chunleimycin is a low-toxic fungicide for agricultural antibiotics. It has strong systemic permeability and has preventive and therapeutic effects. Its therapeutic effect is more remarkable. Its mechanism of action is an esterase system that interferes with the amino acid metabolism of pathogenic bacteria, destroys the biosynthesis of proteins, inhibits the growth of mycelium and causes granulation of cells, and causes the pathogens to lose their ability to multiply and infect, thereby achieving the purpose of killing pathogenic bacteria and preventing diseases. It has been more than 30 years since it was promoted and used in China. It should be noted that soybeans, alfalfa, and cedar (especially seedlings) are more sensitive to spring serotonin, and should be prevented from drifting to the above crops when applying.
