Fungicide Pesticide Mancozeb 80% WPManacozeb is a commonly used fungicide approved for use in the EU and in manny other countries. It has a low aqueous solubility, is quite volatile and not expected to leach to groundwater. It is not persistent in soil systems but may be persistent in water under certain conditions. Mancozeb has a low mammalian toxicity by has been associated with adverse reproduction/development effects. It is highly toxic to fish and aquatic invertebrates, and moderately toxic to birds and earthworms. The toxicity of mancozeb to honeybees is low.
