Diethofencarb is a systemic carbamate fungicide with both protective and curative activities used for the control especially of benzimidazole-resistant strains of fungi, including Botrytis spp., Cercosporu spp. and Venturia spp. It is almost ineffective against benzimidazole- susceptible strains. It is used on vines, cucurbits, tomatoes, citrus, vegetables and other crops.

??

ChEBI: A carbamate ester that is the isopropyl ester of (3,4-diethoxyphenyl)carbamic acid. A fungicide with strong activity against Botrytis cinerea and benzimidazole-resistant strains of Botryis spp.

???

Low toxicity by ingestion, inhalation, and skin contact.

?? ?? ??

In aerobic upland soils under laboratory conditions, the half-life of 14C-diethofencarb is 0.3-6.2 days and the major metabolite is a nitrated derivative at the 6-position of the phenyl ring. Diethofencarb slowly degrades under anaerobic upland conditions and hardly degrades in sterilized soils.
