Herbicide Pesticide & Metabolite Bentazone 100g/L + Mcpa 120g/L SL
Bentazone
Bentazone is a herbicide approved for use in the EU. It is highly soluble in water, volatile and, as it is mobile, may present a risk of leaching to groundwater. It is not likely tyo be persistent in soil systems but may be persistent in water under certain conditions. It is moderately toxic to humans and a recognised skin and eye irritant. Bentazone is also moderately toxic to birds, fish, aquatic invertebrates and earthworms.
