Dichlone (trade names Phygon and Quintar) is a fungicide and algicide of the quinone class. It is a general use fungicide applied to fruits, vegetables, field crops, ornamentals, and residential and commercial outdoor areas.[1] It is also used to control blue algae.[2]

Dichlone is not persistent in soil and has moderate mammalian toxicity.[2]

Dichlone can be manufactured by the chlorination and oxidation of naphthalene.[3]
