Mode of Action and uses

Chlorothalonil is a chloronitrile non-systemic foliar fungicide with protective action.

It controls many fungal diseases in a wide range of crops, including pome fruit, stone fruit, citrus fruit, bush and cane fruit, cranberries, strawberries, pawpaws, bananas, mangoes, coconut palms, oil palms, rubber, pepper, vines, hops, tomatoes, cucurbits, tobacco, coffee, cocoa, tea, rice, soybeans, beans, peas, peanuts, potatoes, sugar beet, cotton, maize, ornamentals, mushrooms, and turf.

It has a multisite mechanism of action: conjugation with, and depletion of, thiols (particularly glutathione) from germinating fungal cells, leading to disruption of glycolysis and energy production, fungistasis and fungicidal action.
