Zineb is also a female name who is originally Arab. Some people claim it to mean a "father's most precious jewel" or "the most important family member". It is sometimes written as Zaynab, Zainab, Zeinab, ...
Production and applications
It is produced by treating ethylene bis(dithiocarbamate) sodium salt, "nabam", with zinc sulfate. This procedure can be carried out by mixing nabam and zinc sulfate in a spray tank. Its uses include control of downy mildews, rusts, and redfire disease. In the US it was once registered as a "General Use Pesticide", however all registrations were voluntarily cancelled following an EPA special review. It continues to be used in many other countries.
Zineb is a polymeric complex of zinc with a dithiocarbamate. The polymer is composed of Zn(dithiocarbamate)2 subunits linked by an ethylene (-CH2CH2-) backbone. A reference compound is [Zn(S2CNEt2)2]2, which features a pair of tetrahedral Zn centers bridged by one sulfur center.
