Background
Berberine is quaternary amine isoquinoline alkaloid, and mainly exists in Coptidis rhizoma of Ranunculaceae, cortex Phellodendri of Rutaceae, and radix Berberidis Amurensis of berberidaceae. The composition has good control effects on various diseases such as apple rot, ring spot, cucumber downy mildew, pumpkin powdery mildew, tomato gray mold, tea leaf cloud leaf blight, pepper phytophthora blight and the like; the results of indoor bioassay and field pesticide effect determination show that berberine has good control effects on tomato early blight, pepper anthracnose, tomato gray mold, cucumber powdery mildew and the like
The benzothiostrobin is a novel nicotinamide fungicide developed by Pasf company in Germany, has wide bactericidal spectrum and has protection and treatment effects. Belongs to succinate coenzyme Q reductase inhibitors in mitochondrial respiratory chain, is suitable for preventing and treating powdery mildew, gray mold, various rot diseases, brown rot diseases, root rot diseases and the like of rape, beans, vegetables, peanuts, potatoes, strawberries, cabbages, sunflowers, grapes, lawns, fruit trees and the like; the benzothiostrobin has no cross resistance with triazole fungicide.
