Chlorimuron-Ethyl 25% WP Herbicide PesticideChlorimuron-ethyl is a post-emergence, foliar applied herbicide without EU regulatory approval for use. It has a high aqueous solubility, is non-volatile and, based on its chemical properties, is mobile and can be expected to leach to groundwater. It can be moderately persistent in soil systems but will not usually persist in aquatic systems. It is generally susceptible to hydrolysis. It has a low mammalian toxicity and has a high potential to bioaccumulate. It is relatively non- toxic to most aquatic species, birds and earthworms but moderately toxic to honey bees.
Description: Post-emergence, foliar applied herbicide used to control broad-leaved weeds in a range of crops including peanuts and soya beans.
