FUNGICIDES

摘要

The invention provides the use in combating fungi of compounds of general formula (I) wherein R<1> is hydrogen, hydroxy, acyl, acyloxy, optionally substituted amino, R<a>, R<a>3Si, RaS or R<a>O, where R<a> is optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted cycloalkyl, optionally substituted cycloalkenyl, optionally substituted aryl or optionally substituted heterocyclyl; R<2> has the same meaning as R<a> or can be hydrogen; Z is oxygen or sulfur; M is a thiophene ring; and R<3> and R<4>, which may be the same or different, have the same meaning as R<a> or can be optionally substituted amino, hydrogen, halogen, cyano, nitro or a group OR<c> or S(O)mR<c>, where R<c> has the same meaning as R<a> or is hydrogen or acyl and m is 0, 1 or 2; or R<3> and R<4> together with the atoms to which they are attached form an optionally substituted carbocyclic or heterocyclic ring; together with tautomers of compounds where R<1> is hydrogen.
