Ziram or zinc dimethyldithiocarbamate is primarily used as an agricultural fungicide to control and prevent the spread of fungal infections. It functions as a protectant fungicide, which means it remains active on the plant’s surface where it forms a chemical barrier between the plant and a fungus. A protectant fungicide is not absorbed into the plant and must be applied prior to infection. Ziram can either be directly sprayed on to a plant’s leaf or it can be used as a soil and seed treatment. The top five crops ziram is used on are: almonds, peaches, nectarines, pears, and table and raisin grapes.
