| | Demosan Usage And Synthesis |
| 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 | Colorless crystalline solid. Musty odor | | Chemical Properties | beige powder | | Uses | 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 | | Trade name | CHLORAXYL® SEED TREATER; DELTA-COAT® II; DEMOSAN®; SOIL FUNGICIDE®-1823; TERSAN® SP; TERRANEB® SP; SOIL FUNGICIDE 1823® | | 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. | | Shipping | UN2761 Organochlorine pesticides, solid, toxic,
Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
UN3077 Environmentally hazardous substances, solid,
n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous
material, Technical Name Required. | | Incompatibilities | May react with strong oxidizers such as
chlorates, peroxides, nitrates, etc | | 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. |
