Fungicidal compositions, fungicidal compounds, their production and use

Abstract

##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.
