Demosan

Описание

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).

Фармаколо?гия

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).

Утилизация отходов

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.
