Stable, easy to decompose into carbon disulfide, and easy to decompose to release carbon disulfide in case of alkaline substances or copper, mercury and other substances, and the effect is reduced, and the volatility is small. The so-called protection is to provide Zn element for plants. In addition to solving the symptoms of zinc deficiency, it can enhance the ability of plants to resist diseases, so as to play a relatively bactericidal effect.

Because of its wide bactericidal range, not easy to produce resistance, and its control effect is obviously better than other similar fungicides, the international dosage has always been a large-tonnage product. At present, most of the compound fungicides are processed and formulated with mancozeb. The trace elements of manganese and zinc have obvious effects on crop strength and yield increase. After more than ten years of field application, it is effective in preventing pear scab and apple spot. The effects of leaf leaf disease, melon and vegetable blight, downy mildew, field crop rust, etc. are remarkable, and the occurrence of diseases can be effectively controlled without any other fungicides, and the quality is stable and reliable.

Main control objects: pear scab, citrus scab, canker, apple leaf spot, grape downy mildew, lychee downy mildew, phytophthora blight, green pepper blight, cucumber, cantaloupe, watermelon downy mildew, tomato blight, Cotton boll rot, wheat rust, powdery mildew, maize large spot, stripe disease, tobacco black shank, yam anthracnose, brown rot, root neck rot, spotted leaf rot, etc.

(1) During storage, care should be taken to prevent high temperature and keep it dry, so as not to decompose the drug under high temperature and humid conditions and reduce the efficacy of the drug.
(2) In order to improve the control effect, it can be mixed with a variety of pesticides and chemical fertilizers, but cannot be mixed with alkaline pesticides, chemical fertilizers and copper-containing solutions.
