MANCOZEB

A contact fungicide belonging to the dithiocarbamate group, widely used for the preventative control of numerous fungal diseases in horticultural, fruit, cereal, and field crops. It acts in a multi-site manner, simultaneously interfering with multiple enzymes and essential metabolic processes of the fungus, especially by inactivating sulfhydryl (-SH) groups involved in cellular respiration and energy production. This causes severe metabolic disturbances that prevent spore germination and mycelial growth. It exhibits exclusively preventative activity and high surface persistence, forming a protective barrier on the plant. It is particularly effective against downy mildew, Alternaria, anthracnose, and numerous foliar diseases. Its multi-site action and low risk of resistance have historically made it a benchmark in resistance control programs and integrated disease management.
