Description

Introduction and Mode of Action: Captan is a protective fungicide from the phthalimide group, capable of controlling a wide range of plant diseases. It has multiple modes of action, and its fungicidal activity is likely due to inhibition of amino acid synthesis and enzymes containing thiol (-SH) groups.
