Mancozeb
Mancozeb is an excellent protective fungicide and belongs to low toxicity pesticide. Due to its wide range of sterilization, its resistance is not easy to produce, and its control effect is significantly better than other similar fungicides, so its dosage has always been a large-tonnage product in the world. At present, most of the compound fungicides in China are processed and prepared with Daisen manganese and zinc. The trace elements of manganese and zinc have obvious effects on the growth and yield of crops. Through more than ten years of field application, they have significant effects on the prevention and control of pear scab, apple spot defoliation, melon and vegetable phytophthora, downy mildew, and field crop rust. Without any other fungicides, the disease can be effectively controlled, with stable and reliable quality.
