Mode of Action | Chlorothalonil is a broad-spectrum protective fungicide. Chlorothalonil can interact with glyceraldehyde-3-phosphate dehydrogenase in fungal cells and combine with the protein containing cysteine in the enzyme, thereby destroying the activity of the enzyme and causing the metabolism of fungal cells to be damaged and lose their vitality. Chlorothalonil has no systemic conductivity, but after spraying on the plant body, it has good adhesion on the body surface and is not easily washed away by rain, so the efficacy period is long. |
