Features of Mancozeb
1. Wide Sterilization Range: Mancozeb can prevent (and control) various crops’ downy mildew, late blight, anthracnose, leaf spot, leaf drop, leaf blight, ring spot, white rot, scab, black core disease, powdery mildew, black leg disease, and more.
2. Stable and Excellent Fungicidal Performance: There is no significant resistance of pathogens to mancozeb, allowing it to be applied multiple times on the same crops or in the same field without the need to switch to different fungicides. Additionally, its residue is relatively low (generally tending towards zero two months after application), making it safe for crops.
3. Good Compatibility: Mancozeb can be mixed and used with various fungicides and insecticides (such as difenoconazole, fluorosilicone, prochloraz, carbendazim, thiophanate-methyl, metalaxyl, Bordeaux mixture, chlorothalonil, and dimethomorph), as well as foliar fertilizers. Especially when mixed with systemic fungicides, it can not only enhance efficacy and prolong the duration of effectiveness but also delay the development of resistance to systemic agents while expanding its sterilization range.
4. More Stable Molecular Structure Compared to Other Similar Fungicides: When sprayed on crops, mancozeb’s conversion is more stable and controllable, which in turn promotes better efficacy against diseases and higher safety for crops.
5. Good Nutritional Components: In addition to its strong fungicidal ability, when applied during crop growth, the zinc and manganese contained in the formulation can also be absorbed by crops to promote their growth and development (zinc is beneficial for the growth of young buds and tender leaves, while manganese is an essential element for photosynthesis in leaves), enhancing the crops’ resistance to stress.
6. Low Usage Cost: Compared to other fungicides, its cost per acre is lower.
Application
For crops such as corn, wheat, peanuts, sorghum, rice, and tomatoes, seed coating, soaking, and mixing methods can prevent seed-borne diseases and soil-borne diseases at the seedling stage. For field crops and vegetables, the application rates are generally 40 to 50 liters of solution per acre for manual spraying, 7 to 10 liters per acre for tractor spraying, 1 to 2 liters per acre for aerial spraying, and 200 to 300 liters per acre for manual spraying on fruit trees. In addition to disease prevention, it also stimulates plant growth, typically using a dilution of 600 to 800 times the 75% mancozeb wettable powder.
