zineb Uses

 Uses of Zineb (CAS NO.12122-67-7) 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 Production

  Zineb (CAS NO.12122-67-7) is produced by reacting Ethylene bis(dithiocarbamate) sodium salt, Nabam, with Zinc sulfate . This can be carried out by mixing nabam and zinc sulfate in the spray tank.

zineb Specification

 Zineb ,its cas register number is 12122-67-7. It also can be called Carbamodithioic acid, N,N'-1,2-ethanediylbis-, zinc salt (1:1) ; Zinc 1,2-ethanediyldicarbamodithioate ; Zinc ethane-1,2-diylbis(dithiocarbamate) ; 1,2-Ethanediylbiscarbamodithioic acid zinc complex and carbamodithioic acid, 1,2-ethanediylbis-, zinc salt (1:1) . Zineb (CAS NO.12122-67-7) is a foliate fungicide and is a polymeric complex of zinc with the ethylene bis(dithiocarbamate) anionic ligand. Ethylene bis(dithiocarbamate) (Maneb) was included in a biocide ban proposed by the Swedish Chemicals Agency and approved by the European Parliament in January 13, 2009.
