Abstract
This invention relates to copper modified mancozeb (the reaction product of manganese ethylene-bis-dithiocarbamate and soluble zinc (II) ion) and processes for preparing same which produces a product which reduces the generation of ethylene thiourea on long term storage of the product, reduces the solubilized ethylene thiourea produced during the manufacture or storage of mancozeb, maintains or increases the fungicidal activity of mancozeb, and is more persistent in the field.
Claims5
