The present invention relates to novel substituted guanidine and amidine compounds, their preparation and their use in the kill and control of fungal organisms which infest plants.

Substituted guanidine and amidine compounds, and fungicidal use

##STR1## Agricultural fungicidal compositions comprising compounds of formula (I-A), (I-B) or (I-C), wherein R.sup.1 and R.sup.7 are each independently hydrogen or C.sub.1 -C.sub.3 alkyl, R.sup.2 is hydrogen or C.sub.1 -C.sub.6 alkyl, R.sup.3 and R.sup.4 independently, and each R.sup.5 independently are hydrogen or C.sub.1 -C.sub.4 alkyl, R.sup.6 is a cyclohexyl group or a monocyclic or bicyclic aromatic group, substituted with from 1 to 5 groups of the formula R.sup.8, wherein R.sup.8 is halogen, a C.sub.1 -C.sub.10 alkyl group, a C.sub.1 -C.sub.10 alkoxy group, a tri-C.sub.1 -C.sub.4 -alkylsilyl group, or a phenoxy, phenyl, phenyl-C.sub.1 -C.sub.2 -alkylene, or phenyl-C.sub.2 -alkenylene group, each optionally substituted on the phenyl or phenoxy group with one or more of halogen atoms, C.sub.1 -C.sub.6 alkyl or C.sub.1 -C.sub.6 alkyl or C.sub.1 -C.sub.6 alkoxy group, trihalomethyl groups, phenyl groups, or phenoxy groups, p is 0, 1 or 2, Y is a group of the formula --(CR.sup.9 R.sup.9).sub.n --, wherein n is 2, 3, or 4, each R.sup.9 independently is hydrogen or C.sub.1 -C.sub.4 alkyl and X is a suitable counter-ion, together with an agriculturally acceptable carrier or diluent, and novel fungicidal compounds of formula (I-A), (I-B), or (I-C), wherein p is 1 or 2 and n is 3 or 4.
