Zineb is a chemical compound from the group of dithiocarbamates. It is in the form of a crystalline powder.

Production and representation

Zineb can be obtained by reaction of nabam with zinc sulfate.

Use

Zineb was used as a broad-spectrum pesticides (leaf fungicide) in a number of fruits and vegetables. It was also used with other combination with similar substances (eg as Metiram ). The registration as plant protection products was lifted in the EU and in Switzerland in 2001. Zineb is used as a biocide in antifouling products. For use in product-type 21, it was included in the EU test program.

Safety

Zineb is only slightly toxic, but hormonal effects.

Proof

Zineb can be detected by HPLC using similar thiocarbamates distinguished by subsequent atomic spectroscopy and the mixing ratio can be determined.
