Zineb
    代森锌
Introduction: Zineb is a polymeric complex of zinc with the ethylene bis(dithiocarbamate) anionic ligand. It is used as a fungicide to control downy mildews, rusts and redfire disease. Zinc is a metallic element with the atomic number 30. It is found in nature most often as the mineral sphalerite. Though excess zinc in harmful, in smaller amounts it is an essential element for life, as it is a cofactor for over 300 enzymes and is found in just as many transcription factors.

ENVIRONMENTAL FATE
EHC 78 (WHO, 1988; general review of dithiocarbamates). Plants Ethylenethiourea is the major metabolite in plants. Ethylenethiuram monosulfide and presumably ethylenethiuram disulfide and sulfur are also formed.
Usage: Zineb is introduced by Rohm & Haas Co. (now Dow AgroSciences), and by E. I. du Pont de Nemours and Co., (who no longer manufacture or market it). It is used to protect fruit and vegetable crops from a wide range of foliar and other diseases.
Application: Biochemistry Non-specific thiol reactant, inhibiting respiration. Mode of action Foliar fungicide with protective action. Uses Control of downy mildews in vines, hops, lettuce, onions, spinach, brassicas, oilseed rape, tobacco, and ornamentals; rusts in currants, berry fruit, plums, vegetables, and ornamentals (especially carnations and chrysanthemums); red fire disease on vines; potato and tomato blights; leaf spot diseases on currants, berry fruit, olives, and celery; anthracnose on beans, vines, and citrus fruit; scab on apples and pears; shot-hole on stone fruit; Cercospora on bananas; tulip fire; Botrytis; needle cast in forestry; etc. Phytotoxicity Non-phytotoxic, except for zinc-sensitive plants such as tobacco and cucurbits.
