Fungicidal compositions, fungicidal compounds, their production and use

An agricultural fungicidal composition comprising a fungicidally effective mount of a compound of the formula:

• ##STR17## 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 phenyl or phenyl substituted with from 1 to 5 groups of the formula R.sup.8,
• R.sup.8 is halogen, C.sub.1 -C.sub.10 alkyl, C.sub.1 -C.sub.10 alkoxy, tri-C.sub.1 -C.sub.4 -alkylsilyl, phenoxy, phenyl, phenyl-C.sub.1 -C.sub.2 -alkylene, or phenyl-C.sub.2 -alkenylene, provided that any R8 that includes a phenyl ring may be substituted on the phenyl ring with one or more groups selected from halogen, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkoxy, trihalomethyl, phenyl, or phenoxy,
• Y is a group of the formula --(CR.sup.9 R.sup.9).sub.3 --, wherein
• 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.
