Mancozeb is a broad spectrum protectant fungicide.Technical purity: 85% Min. TCFormulation: 80% WP, 300G/L SCCommom name: MancozebChemical name: [1,2-Ethaznediybis(carbamodithio)(2-)manganese zinc salt]Molecular Formula: (C4H6N2S4Mn)x(Zn)y A coordination product of Zinc ion and Manganese ethylene bis-dithio-carbamate.It is a multi-site protective fungicide for control of a wide range of fungal diseases in horticulture, floriculture, and field crops. Sticks on leaves so that rain does not affect. It is bio-degradable and does not accumulate in the environment. Pre-harvest intervals (PHI)Tomatoes, potatoes, and vegetables 3daysAll other edible crops7daysCitrus14daysGrapes 28daysPhysical Chemistry: Grayish yellow powder. Vapour Pressure: Negligible.Melting Point: 192 to 204Solubility in water: Practically insoluble in water.Solubility in organic solvent: Practically insoluble in most organic solvents.Toxicity: The acute oral LD50 for mancozeb was 4,500 mg/kg.The acute dermal (skin) LD50 for mancozeb was greater than 5,000 mg/kg.Mancozeb was mildly irritating to the skin with a primary irritation score (PIS) of 0.5.Mancozeb caused moderate eye irritation with a PIS of 2.3.Mancozeb has an acute inhalation to LC50 of greater than 5.14 mg/L.Mancozeb is used to controlLophodermium needle cast, Pine gall rust, and Scirrhia brown spot in conifers and Swiss needle cast in Douglas Fir.Application:It inhibits enzyme activity in fungi by forming a complex with metal-containing enzymes including those involved in production of adenosine triphosphate. It is for the prevention and treatment of vegetables, fruit trees, flowers and food crops and other cash crops downy mildew, leaf spot, the disease, such as scab.Mode of action:A contact fungicide with protective activity. It forms a slight film on the surface of the plant and gradually releases several degradation compounds, which disrupt the respiratory activity of the target fungi at several points of metabolic pathway. It is active against spore germination.Spectrum of use:l Used against peronosporal diseases such as early and late blights, downy mildew, spot, rhizoctonia, scab, puccinia and septoria on fruit trees, vegetable (potatoes, tomatoes, onion, garlic, cucurbits etc), tobacco and ornamentals.l Contains zinc and manganese which are needed to the cropDirections for use:To be fully effective, it must be used as preventive spray and therefore applied before the disease appears. Thorough coverage of the plant is essential. Repeat sprays every 7-10 days, applying at the shorter interval during heavy rain or if overhead irrigation is used.
