Chlorothalonil is a broad-spectrum, protective fungicide. Its mechanism of action is that it can interact with glyceraldehyde triphosphate dehydrogenase in fungal cells, combine with the protein containing cysteine in the enzyme, and destroy the enzyme. Enzyme activity destroys the metabolism of fungal cells and loses their vitality. Chlorothalonil has no systemic conduction effect, but after sprayed on the plant body, it can have good adhesion on the body surface, is not easy to be washed away by rain, and has a long drug effect period.

Effect of chlorothalonil

The main role of chlorothalonil is to protect plants from fungal attack. After the plant has been attacked by the pathogen and the germ enters the plant, the bactericidal effect is very small.
