1-Aminocyclohexanecarboxylic acid derivatives of the formula I ##STR1## or their acid addition salts or a metal complex can be employed for protecting plants from microorganisms. In the formula I, R.sub.1 is hydrogen or C.sub.1 -C.sub.4 alkyl, R.sub.2 is hydrogen, C.sub.1 -C.sub.6 alkyl, benzyl, or an ammonium radical which is unsubstituted or substituted by hydrocarbon radicals having not more than 20 C atoms, or a metal ion equivalent. Compounds of the formula I can be employed in the form of crop protection agents using suitable carrier materials.

Microbicidal compositions

An agent for influencing plant growth, in particular a herbicidal and plant growth inhibiting agent, contains, in addition to carriers and/or other additives, at least one compound of the formula: ##STR1## or the corresponding zwitterion form in which R and R.sub.1 may be the same or different and each can be hydrogen, deuterium or an optionally substituted lower alkyl group, lower alkenyl, lower alkynyl, cycloalkyl, aryl or heterocyclic radical containing one or more oxygen, nitrogen or sulphur atoms and which may be fused to an aromatic ring, a lower alkyl group substituted by a cycloalkyl radical, a lower alkyl group substituted by an aryl radical, a lower alkyl group substituted by a heterocyclic radical as defined above, or R and R.sub.1 together form a polymethylene chain optionally interrupted by an oxygen, nitrogen or sulphur atoms, or R.sub.1 represents, together with the C(R)--N&lt; residue to which it is attached, the atoms required to complete a heterocyclic radical; and R.sub.2 and R.sub.3 may be the same or different and each can be hydrogen, optionally substituted lower alkyl, cycloalkyl, aryl or lower alkyl substituted by a heterocyclic radical containing one or more nitrogen atoms; or R.sub.2 and R.sub.3, independently, together with the &gt;C(H)--N&lt; residue to which each is attached, may each represent the atoms required to complete a heterocyclic radical; R.sub.6 is OH, CH.sub.3, or phenyl; R.sub.7 is hydrogen or a lower alkoxycarbonyl, cycloalkoxycarbonyl, aryloxycarbonyl or benzyloxycarbonyl group; and m is 0 or 1; n is 0, 1, 2 or 3; as well as the esters or partial esters thereof with physiologically splittable alcohols; salts of the compounds of formula I, or their esters or partial esters with acids or bases physiologically acceptable to plants, respectively; and all optical isomers thereof; provided that when R.sub.7 is hydrogen and m and n are each 0, then R.sub.6 is not OH.
