Fungicide Pesticide Chlorothalonil 50g/L + Dimethomorph 100g/L SC
ChlorothalonilChlorothalonil is a broad spectrum fungicide that is approved for use in the EU and is widely used. It has a low aqueous solubility, is volatile and would not be expected to leach to groundwater. It is slightly mobile. It tends not to be persistent in soil systems but may be persistent in water. It has a low mammalian toxicity but there is some concern regarding its bioaccumulation potential. It is a recognised irritant. Chlorothalonil is moderately toxic to birds, honeybees and earthworms but considered to be more toxic to aquatic organisms.
Description: A fungicide used to control a wide range of diseases on a broad range of crops. Also used as a wood preservative.
