What is Demosan?
Description
Chloroneb was developed by Du Pont de Nemours Co. in 1967. It differs from the compounds described above in that it does not contain nitro-groups. In common with other chlorobenzene fungicides, chloroneb has a low mammalian toxicity and a significant vapor pressure so that it was used as a soil fungicide in the culture of beans, cucumber, and cotton (20). In contrast with the nitrobenzene compounds, Phytophthora spp. are rather sensitive to chloroneb. Pythium spp. vary in sensitivity to chloroneb. Because of its low water solubility, chloroneb is only very weakly systemic (21,22).
Chemical properties
beige powder
Chemical properties
Colorless crystalline solid. Musty odor
The Uses of Demosan
Chloroneb-D6 is a labelled analogue of Chloroneb (C370935). Chloroneb is a fungicide that has selective activity against certain fungi (e.g. Mucor and Pythium fungi), and is most commonly used for cotton seedlings and bean plants.
Definition
ChEBI: A dimethoxybenzene that is p-dimethoxybenzene which is substituted by chlorines at positions 2 and 5. A fungicide formerly used as a seed treatment, it is not approved for use in the European Union.
General Description
White to tan solid or beige powder. Musty odor.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Demosan is stable at temperatures up to 514° F, in water in the presence of dilute acids or alkalis, and in the common organic solvents. Demosan is subject to microbial decomposition in soil under moist conditions.
Fire Hazard
Demosan is combustible.
Agricultural Uses
Fungicide: A systemic fungicide used to control snow mold on turf grass; used on cotton, sugar beets and bean seeds to control seedling disease. Not approved for use in EU countries. Registered for use in the U.S. except California

Pharmacology
Chloroneb is not effective against Fusarium but has a relatively broad spectrum of activity compared with other compounds that are specifically active against oomycetes (24). By controlling Rhizoctonia solani, by seed-piece or in furrow applications, chloroneb increased potato yields in Texas (25).
Potential Exposure
An organochlorine/substituted benzene systemic fungicide used to control snow mold on turf grass; used on cotton, sugar beets and bean seeds to control seedling disease. Not approved for use in EU countries.

Waste Disposal
Do not discharge into drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill.Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Incineration with effluent gas scrubbing is recommended. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
