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.

生产方法
(1)二甲基二硫代氨基甲酸钠的制备先将固碱在反应釜内配成15%的水溶液,再加入二硫化碳和二甲胺,搅拌下微微加热,保持温度于40～45℃,进行缩合反应1h以上。至体系pH值为9～10时,所得浅黄绿色或琥珀色液,即为二甲基二硫代氨基甲酸钠。 ZDMC是应用于NR，lR，SBR，NBR，llR，和EPDM主促进剂或助促进剂。硫化速度比TMTD快，有很好的抗焦性。很少单独用，通常作为助促进剂。硫化温度低，硫化速度快。为安全生产，通常需和噻唑类促进剂并用。本品无味无毒，可以用于制造与食品接触的橡胶制品。
