• Effects of Short Term Exposure: The substance is severely irritating to the eyes. The substance is irritating to the skin and respiratory tract.
• Effects of Long Term Exposure: Repeated or prolonged contact may cause skin sensitization. Tumours have been detected in experimental animals but may not be relevant to humans.
• Uses: Ziram is a protective fungicide applied to foliage to control diseases on pome fruit, stone fruit, nuts, vines, vegetables and ornamentals. It is used to control scab in apples and pears and Monilia, Alternaria, Septoria, peach leaf curl, shot hole, rusts, black rot and anthracnose. It is also used as a wildlife repellent, smeared as a paste onto tree trunks or sprayed onto ornamentals, dormant fruit trees and other crops. Zinc Dimethyldithiocarbamate is a member of a class of dithiocarbamates, and has been used in agriculture as a fungicide and in the rubber industry as a vulcanization accelerator. Rubber vulcanization accelerator; agricultural fungicide.
