ABSTRACT:
The invention is directed to fungicidal pyridine derivatives and their N-amino salts and acid addition salts, said pyridine derivatives having the formula ##STR1## wherein R is mono-, di- or trisubstituted phenyl, wherein the substituents are the same or different and are selected from the group consisting of 1 to 3 halogen, 1 or 2 C.sub.1-3 -alkyl, 1 or 2 C.sub.1-3 -alkoxy and 1 or 2 trifluoromethyl moieties; R.sup.1 is hydrogen, C.sub.1-6 -alkyl, C.sub.2-6 -alkenyl or C.sub.2-6 -alkynyl; R.sup.2 is hydrogen; R.sup.3 is selected from the group consisting of --CO--R.sup.4, --C(OR.sup.5).dbd.CHR.sup.6, --CH(R.sup.4)OR.sup.5, --C(R.sup.4).dbd.NOR.sup.7 and ##STR2## R.sup.4 is hydrogen or C.sub.1-5 -alkyl; R.sup.5 is C.sub.1-4 -alkyl; R.sup.6 and R.sup.7 are hydrogen or C.sub.1-4 -alkyl; n is 2 or 3; or R.sup.2 taken together with R.sup.4 is equal to the group --CH.dbd.CH-- (vinylene); as well as to fungicidal compositions containing these compounds as the active substance, and to the use of the fungicidal pyridine derivatives, their N-amino salts and their acid addition salts in a method of combatting the growth of fungi in agriculture and in horticulture.
