Mode of Action:
-Chlorothalonil: It acts mainly by inhibiting the respiration of fungi, interfering
with the normal physiological processes of fungal cells.
-Pyrimethanil: It inhibits the synthesis of fungal proteins and affects the growth
and development of fungi.
-The combination has a dual-action mechanism, which can effectively control
various fungal diseases.
Benefits:
-Broad-spectrum fungicidal activity, suitable for multiple crops.
-Good preventive and curative effects on fungal diseases.
-Low residue on crops, meeting food safety requirements.
