Study on Mancozeb + Carbendazim Fungicides for Plant Disease Management
Introduction Mancozeb is a dithiocarbamate non-systemic agricultural fungicide with multi-site, protective action on contact. It is a combination of two other dithiocarbamates : maneb and zineb. Fig: Mencozeb
Carbendazim Carbendazim is a widely used, broad-spectrum benzimidazole fungicide and a metabolite of benomyl . Fig: Carbendazim
Chemical name: Carbendazin12%+Mancozeb63%WP Chemical name: Methyl 1H benzimidazol-2-ylcarbamate + Manganese ethylenebis ( dithiocarbamate ) (Polymeric) complex with zinc salt Molecular formula: C 9 H 9 N 3 O 2 + (C 4 H 6 MnN 2 S 4 ) x Zny Formulation: Wetable powder

Nature of fungicide Carbendazim : Systemic with curative and protectant activity. Inhibition of mitosis and cell division (Beta-tubulin assembly in mitosis). & Mancozeb : Broad spectrum, non-systemic, contact with protective action, acts by distrupting lipid metabolism.
Mode of action Carbendazim works by inhibiting the development of fungi probably by interfering with spindle formation at mitosis (cell division). It is a broad spectrum systemic protective and curative fungicide. It inhibits the development of germ tubes, formation of appresoria and the growth of mycelia by inhibiting cell division. Mancozeb is a dithiocarbamates and affects the nervous system through their main metabolite, carbon disulfide. It is a multisite protective fungicide and inhibits spore germination and remains on the leaf surface and interfers with six different biochemical processes within fungal pathogen cell. It contains a systemic fungicide carbendazim and a contact fungicide mancozeb and ensures double protection from inside and from outside.
Recommended Crops: Rice, ground nut, potato, chili, tea, mango, grape etc. Recommended Diseases: leaf spot, blast, Tikka leaf spot, Collar rot & Dry root rot, Leaf spot, fruit rot and powdery mildew, Downy mildew, Ealry blight, Late blight, Black scurf etc .
Application Timing & Method: The product should be sprayed immediately on appearance of disease symptoms. As per recommendation, mix the pesticide and water at right dosages and spray. Spray by using high volume sprayer viz. knapsack sprayer. Use 500-1000 litres water per hectare. Before spraying the pesticide, its suspension should be mixed well with a wooden stick.
Compatibility It is compatible with commonly used pesticides. It is not compatible with lime sulphur and Bordeaux mixture or alkaline solutions. It is advisable to conduct a physical compatibility test before use in combination with other molecules.
Handling and storage Packages or surplus material and washing from the machines and cointainer shall be disposed off in such a manner so as to prevent environmental or water pollution. The used packages should not be left outside to prevent their re-use. Packages should be burried away from habitation and source of water.
Packaging: Available in 50 gm, 100 gm, 250 gm, 500 gm and 1 Kg laminated pouch . Hazard : Physical hazard- Release toxic fumes if burned Environmental hazard- Toxic to aquatic life. Toxic to fish and aquatic invertebrates. Human hazard- Sweating, headache, lethargy, coughing, sneezing, itching, nausea, vomiting may occur.
Precaution 1) Keep away from foodstuffs, empty foodstuff containers and animals feed. 2) Avoid contact with mouth, eyes and skin. 3) Avoid inhalation of the spary mist. Spray in the direction of wind. 4) Wash throughly the contaminated clothes and parts of the body after spraying. 5 ) Do not smoke, drink eat and chew anything while spraying. 6) Wear full protective clothing while mixing and spraying
Conclusion Carbendazim12% & Mancozeb 63 % found to be quite effective however, high dose was most effective in reducing spore germination and mycelial growth. It was concluded that the use of the Carbendazim-Mancozeb mixture should be with caution since it reduced the populations of ecologically important non-target organisms and that the recommended concentration should be adhered .
