Mode of Action – How Captan 50% WP Works
Captan interferes with fungal respiration and enzyme activity by reacting with thiol (–SH) groups in fungal cells. This disrupts energy production and essential metabolic processes, preventing spore germination and fungal growth. Being a contact fungicide, it remains on the plant surface and must be applied before disease establishment for best results.
