Zinc diethyldithiocarbamate is used as a common accelerator to latex.
A fast curing primary or secondary effective ultra-accelerator for natural and synthetic latex compounds.
Known as ziram in agriculture, Zinc diethyldithiocarbamate was introduced in the United States in 1960 as a broad-spectrum fungicide.
Zinc diethyldithiocarbamate was used to address scab on apples and pears, leaf curl in peaches, and anthracnose and blight in tomatoes.
In 1981, additional uses for Zinc diethyldithiocarbamate were approved, including the prevention of leaf blight and scab on almonds, shot-hole in apricots, brown rot and leaf spot in cherries, and scab and anthracnose in pecans.
Zinc diethyldithiocarbamate also began to be used on residential ornaments as a bird and mammal repellent.
As a protectant fungicide, Zinc diethyldithiocarbamate is 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.
Zinc diethyldithiocarbamate 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 Zinc diethyldithiocarbamate is used on are: almonds, peaches, nectarines, pears, and table and raisin grapes.
Alternatively, Zinc diethyldithiocarbamate is used as an additive ingredient in industrial adhesives, caulking, and paint.
Zinc diethyldithiocarbamate also serves as a bird and mammal repellent on outdoor ornamental items.

Chemistry
Zinc diethyldithiocarbamate is a prototypical zinc dithiocarbamate, a broad class of coordination complexes with the formulae Zn(R2NCS2)2, where R can be varied.
Such compounds are produced by treating zinc and dithiocarbamate (R2NCS2−), as illustrated with dimethyldithiocarbamate:
2 (CH3)2NCS2− + Zn2+ → Zn((CH3)2NCS2)2
Annually, approximately 1.9 million pounds of the active Zinc diethyldithiocarbamate are used.
Zinc diethyldithiocarbamate is often sold in powder or granule form.
Zinc diethyldithiocarbamate complexes degrade thermally to give zinc sulfide.
Structure
Compounds of the type Zn(S2CNR2)2 are dimeric, i.e. their proper formula is [Zn(S2CNR2)2]2.
Each Zn center is in a distorted pentacoordinate site, with four Zn–S bonds of 2.3 Å length and one Zn–S interaction is over 2.8 Å in length.
Mono-zinc derivatives are obtained by adding strong ligands (L) such as amines, which give adducts Zn(S2CNR2)2L.
Ecological effects
The U.S. Environmental Protection Agency has concluded that Zinc diethyldithiocarbamate poses a low toxicity risk to mammals, a moderate risk to birds, and a high risk to aquatic species.
After reviewing studies that investigated the effect of Zinc diethyldithiocarbamate on aquatic organisms, the Pesticide Action Network Pesticide Database concluded that its LC50 dose (amount of pesticide that is lethal to 50% of the test organisms within the stated study time) for amphibians places it in the "highly toxic" category.
