Insecticide Pesticide Chlorpyrifos 500g/L + Cypermethrin 50g/L EC
ChlorpyrifosAn organophosphate insecticide approved for use in the EU. It has a low aqueous solubility, is quite volatile and is non-mobile. There is a low risk of leaching to groundwater based on its chemical properties. It can be moderately persistent in soil systems but is not usually persistent in water systems. It is highly toxic to mammals, is classified as a reproduction toxicant, an acetyl cholinesterase inhibitor and a neurotoxicant. It is also a skin and eye irritant. It is highly toxic to birds, fish, aquatic inverterbrates and honey bees and moderately toxic to aquatic plants, algae and earthworms

Cypermethrin is an insecticide that has approval for use in the EU. It has a low aqueous solubility and is volatile. Whilst its chemical properties suggest that it should not leach to groundwater it has been detected. It is considered a serious marine pollutant. It is moderately persistent is soils but is likely to degrade moderately fast in water systems under daylight conditions. It is moderately toxic to mammals and there is some concern regarding its potential to bioaccumulate. Whilst it is an irritant, no serious human health issues have been identified. It is highly toxic to most aquatic species and honeybees. It is moderately toxic to earthworms but there is little risk to birds.
