Mancozeb
Mancozeb
Mancozeb was introduced to the market in 1962 as a broad spectrum fungicide. Mancozeb is a mixture of manganese and zinc and belongs to the dithiocarbamate group of fungicides, within the sub group of compounds called ethylene bisdithiocarbamates (EBDCs). Of the EBDSs maneb, metiram, propineb and zineb also belong to this compound group. It is classified as a multi site action fungicide (affects multiple sites and fungi on the plant). It inhibits spore germination on the plants. Most applications of Mancozeb are foliar. Since Mancozeb is a multi site protectant, it needs to be retreated to counteract weather and plant growth. Mancozeb has a low toxicity rating to mammals. Mancozeb is harmful to birds, wildlife and fish but not hazardous to honey bees.
