Mancozeb is a broad-spectrum contact fungicide which is labeled for use on many fruit, vegetable, nut, and field crops in Minnesota. It provides protection against a wide spectrum of fungal diseases, including potato blight, leaf spot, scab, and rust. It is also used as seed treatment for potatoes, corn, sorghum, tomatoes, and cereal grains. In 2017, approximately 1.1 million pounds of mancozeb were sold in Minnesota.


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. The mixture controls many fungal diseases in a wide range of field crops, fruits, nuts, vegetables, and ornamentals. It is marketed as Penncozeb, Trimanoc, Vondozeb, Dithane, Manzeb, Nemispot, and Manzane. In Canada, a mixture of zoxamide and mancozeb was registered for control of the mildew named Gavel as early as 2008.

Mode of Action

Mancozeb is classified by the Fungicide Resistance Action Committee (FRAC) as a mode-of-action group M, multi-site, fungicide. It interferes with enzymes containing sulphydryl groups, disrupting several biochemical processes within the fungal cell cytoplasm and mitochondria.

Macozeb and Human Health

Since mancozeb is not expected to remain in drinking water long enough to reach a location that would supply drinking water for human consumption, whether from surface or groundwater sources, this is not a likely exposure route. Estimated concentrations of ETU, for both surface and ground water sources of drinking water, were below EPA’s level of concern. Minnesota Department of Health developed rapid assessment value for ETU is 2.0 µg/L.

Major routes of exposure to mancozeb are through the skin or from inhalation. In spray or dust forms, the EBDCs and ETU are moderately irritating to the skin and respiratory mucous membranes. Symptoms of poisoning from this class of chemicals include itching, scratchy throat, sneezing, coughing, inflammation of the nose or throat, and bronchitis. This concern can be reduced by using proper application techniques. There are risk concerns for some occupational handlers which can be mitigated with use of appropriate personal protective equipment.
