Mancozeb 64% + Metalaxyl 8% WP

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.

Metalaxyl NOMENCLATURE
Common name metalaxyl (BSI, E-ISO, (m) F-ISO, ANSI) 
IUPAC name methyl N-(methoxyacetyl)-N-(2,6-xylyl)-DL-alaninate; methyl 2-{[(2,6-dimethylphenyl)methoxyacetyl]amino}propionate
Chemical Abstracts name methyl N-(2,6-dimethylphenyl)-N-(methoxyacetyl)-DL-alaninate 
CAS RN [57837-19-1] 

Metalaxyl APPLICATIONS
Metalaxyl Biochemistry Inhibits protein synthesis in fungi, by interference with the synthesis of ribosomal RNA.

Metalaxyl Mode of action Systemic fungicide with protective and curative action, taken up by leaves, stems and roots.

Metalaxyl Uses To control diseases caused by air- and soil- borne Peronosporales on a wide range of temperate, subtropical and tropical crops. Foliar sprays with mixtures of metalaxyl and protectant fungicides are recommended to control air-borne diseases caused by Pseudoperonospora humuli on hops, Phytophthora infestans on potatoes and tomatoes, Peronospora tabacina on tobacco, Plasmopara viticola on vines, Bremia lactucae on lettuce, and downy mildews on various vegetables, at 200-300 g/ha. Soil applications of metalaxyl alone are used to control soil-borne pathogens causing root and lower stem rots on avocado and citrus, at 500-1500 g/ha. Seed treatments control systemic Peronosporaceae on maize, peas, sorghum and sunflowers, as well as damping-off (Pythium spp.) of various crops.
