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).
