Abstract
A method of combating fungi or regulating the growth of plants which comprises applying to such fungi, such plants or to a fungus or plant growth situs an amount effective therefor of an imidazo-pyrrolo-pyridine of the formula ##STR1## in which R.sup.1 represents cyano, alkoxycarbonyl or aminocarbonyl, R.sup.2 represents hydrogen, alkyl, trimethylsilyl or one equivalent of a metal cation and R.sup.3 and R.sup.4 independently of one another each represent alkyl, cycloalkyl or cycloalkylalkyl or R.sup.3 and R.sup.4 together represent a divalent alkanediyl radical. Many of the compounds are new.

A method of combating fungi or regulating the growth of plants which comprises applying to such fungi, such plants or to a fungus or plant growth situs an amount effective therefor of an imidazo-pyrrolo-pyridine of the formula ##STR32## in which, R.sup.1 represents cyano, aminocarbonyl or straight-chain or branched alkoxycarbonyl with 1 to 4 carbon atoms in the alkoxy part,
- R.sup.2 represents hydrogen or straight-chain or branched alkyl with 1 to 4 carbon atoms, or represents trimethylsilyl, or represents one equivalent of an alkali metal or alkaline earth metal cation, and
- R.sup.3 and R.sup.4 independently of one another each represent straight-chain or branched alkyl with 1 to 6 carbon atoms, or represent cycloalkyl with 3 to 7 carbon atoms, or represent a cycloalkylalkyl which has 3 to 7 carbon atoms in the cycloalkyl part and 1 to 4 carbon atoms in the alkyl part and is straight-chain or branched on the alkyl part, or
- R.sup.3 and R.sup.4 together represent a divalent alkanediyl radical with 4 to 6 carbon atoms.
An imidazo-pyrrolo-pyridine of the formula ##STR35## in which R.sup.1 represents cyano, aminocarbonyl or straight-chain or branched alkoxycarbonyl with 1 to 4 carbon atoms in the alkoxy part,
- R.sup.2 represents hydrogen or straight-chain or branched alkyl with 1 to 4 carbon atoms or represents trimethylsilyl, or represents one equivalent of an alkali metal or alkaline earth metal cation and
- n represents the number 2, 3 or 4.
A fungicidal or plant growth-regulating composition comprising a fungicidally or plant growth regulating effective amount of a compound of the formula ##STR36## wherein R.sup.1 represents cyano, aminocarbonyl or straight or branched alkoxycarbonyl with 1 to four carbon atoms in the alkoxy part and R.sup.2 represents alkyl having 1 to 4 carbon atoms or represents one equivalent of a metal cation;
- and a diluent.
