SUMMARY
Zineb is a fungicide that does not have approval for use within the EU. It has a low aqueous solubility, is relatively volatile and is not expected, based on its physico-chemical propoerties, to leach to groundwater. It is not usually persistent in soil or water systems. Zineb has a low mammalian toxicity however, it may cause adverse reproduction/developement effects if ingested. It is moderately toxic to most fauna and flora. GENERAL INFORMATION
