Dichlone
the generic name for 2,3-dichloro-l,4-naphthoquinone (C10H4O2Cl2), a fungicidal chemical agent used against fungous plant diseases. It is used in the form of an aqueous suspension of 50-percent wettable powder to combat rice blast and spots on plants of the genus Prunus, as well as fungous diseases of vegetable and ornamental crops (with treatment halted 20 days before harvest). The dose here is 2.5–5.0 kg of the preparation per hectare. In the fight against diseases of vegetable crops, the seeds too are dusted with 5 g of 50-percent dichlone powder per 1 kg of seeds. Dichlone is moderately toxic to humans and animals, irritating the mucosa and skin.
