Investigations on fungicides: XIV. Fungitoxicity of N‐(2,2,2–trichloro‐1–methoxyethyl)‐formamide and related compounds

SUMMARY From a study of forty compounds related to the systemic fungicide N,N'‐bis(1–formamido‐2,2,2–trichloroethyl)‐piperazine, known as triforine (CELAW524), it was found that a new compound, N‐(2,2,2–trichloro‐1–methoxyethyl)‐formamide, controls Erysiphe graminis on wheat when applied to the roots in sand. A number of N‐(2,2,2–trichloro‐1–aryloxyethyl)‐form‐amides and alkyl N‐(2,2,2–trichloro‐1–arylaminoethyl)‐carbamates protect broad beans against Uromyces fabae and wheat against Erysiphe graminis; some of these formamides show slight activity when applied to plant roots.
