Mancozeb NOMENCLATURE Common name manzeb (JMAF); mancozeb (BSI, E-ISO); mancozèbe ((m) F-ISO) IUPAC name manganese ethylenebis(dithiocarbamate) (polymeric) complex with zinc salt Chemical Abstracts name [[1,2-ethanediylbis[carbamodithioato]](2-)]manganese mixture with [[1,2-ethanediylbis[carbamodithioato]](2-)]zinc CAS RN [8018-01-7], formerly [8065-67-6]; number also applies to other mixed manganese and zinc ethylenebis(dithiocarbamate) complexes
Mancozeb APPLICATIONS Mancozeb Biochemistry Reacts with, and inactivates, the sulfhydryl groups of amino acids and enzymes of fungal cells, resulting in disruption of lipid metabolism, respiration and production of ATP.
Mancozeb Mode of action Broad-spectrum, non-systemic fungicide with protective action.
Mancozeb Uses Control of many fungal diseases in a wide range of field crops, fruit, nuts, vegetables, ornamentals, etc. More frequent uses include control of early and late blights (Phytophthora infestans and Alternaria solani) of potatoes and tomatoes; downy mildew (Plasmopara viticola) and black rot (Guignardia bidwellii) of vines; downy mildew (Pseudoperonospora cubensis) of cucurbits; scab (Venturia inaequalis) of apples; Sigatoka (Mycosphaerella spp.) of bananas; and melanose (Diaporthe citri) of citrus. Typical application rates are 1500-2000 g/ha. Used for foliar application or as a seed treatment.
Mancozeb Compatibility Not compatible with oxidising agents or acids.
