New phosphoric acid monoester salts which have fungicidal activity and which have the general formula I :. where. Rs a straight-chain or branched alkyl group having 1-13 carbon atoms, which may be optionally substituted by halogen; an alkoxyalkyl group having 1-4 carbon atoms in the alkyl moiety and. 1-5 carbon atoms in the alkoxy moiety or a phenyl group ,. 1 * 2 is alkyl of 6-20 carbon atoms; alkoxyalkyl, phenoxyalkyl, furfuryl, cyclopropyl-alkyl ,. cyclopentyl, cycloheptyl, thiazolyl, triazolyl, thiazolinyl, pyridinyl, picolyl, benzimidazolyl, piperonyl, pyrimidinyl, chlorobenzothiazolyl, benzyl, phenyl substituted with chlorine and / or amino, or amino and alkyl, or amino and nitro groups, alkenyl, alkyl, . dialkylaminoalkyl, alkylaminoalkyl, alkylphosphonate ammonium alkyl, 3,5-dichlorophenylhydantoinyl. or thiadiazolyl optionally substituted with alkyl; R is hydrogen, phenyl, benzyl, alkenyl, alkyl, hydroxy, alkoxy or alkoxyalkyl; or. Rog R.j together form a 3,5-dichlorophenyl-hydantoinyl group; Hydrogen or alkyl, which may be optionally substituted with hydroxy. Fungicidal compositions containing the novel phosphoric acid monoester salts as active ingredient are described, as well as the preparation of the novel phosphoric acid monoester salts. |
