Abstract

The invention provides a fungicidal composition comprising a carrier and, as active ingredient, certain tetrahydropyrimidine derivatives of the general formula ##STR1## or an acid-addition salt or metal salt complex thereof, in which n is 0, 1, 2 or 3; R represents an optionally substituted alkyl, aryl or aralkyl group; R.sup.1 represents a hydrogen atom or an optionally substituted alkyl or aralkyl group; R.sup.2 represents an optionally substituted aryl group; p is 0 or 1; X represents a group --NR.sup.3 -- or --NR.sup.3 --NR.sup.3 -- where each R.sup.3 independently represents a hydrogen atom or an optionally substituted alkyl, aryl or aralkyl group or R.sup.1 and (X).sub.p --A--R.sup.2 together represent a group --(CR.sup.4 R.sup.5).sub.q --N(A--R.sup.2)-- where q is 2 or 3 and each of R.sup.4 and R.sup.5 is independently selected from a group consisting of hydrogen atoms and optionally substituted alkyl groups; and A represents a group --(CR.sup.6 R.sup.7).sub.m -- where m is 0, 1, 2, 3 or 4 and each of R.sup.6 and R.sup.7 is independently selected from a group consisting of hydrogen atoms and optionally substituted alkyl groups.
