    • A method of combating plant-pathogenic bacteria, comprising applying to the bacteria or to a bacteria habitat a bactericidally effective amount of a cyclopropyl-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid derivative of the formula ##STR1## in which A represents straight-chain or branched alkylene with 1 to 6 carbon atoms or a >C.dbd.CH-- radical,R.sup.1 represents alkoxycarbonyl with 1 to 6 carbon atoms in the alkyl part, benzyloxycarbonyl, carboxyl, optionally substituted carbamoyl, cyano or dialkoxyphosphonyl or alkylsulphonyl with 1 to 4 carbon atoms in the alkyl part, andR.sup.2 represents hydrogen, alkoxycarbonyl with 1 to 6 carbon atoms in the alkyl part, benzyloxycarbonyl, optionally substituted carbamoyl, cyano, chlorine, acetyl, alkyl with 1 to 3 carbon atoms or phenyl, orR.sup.1 and R.sup.2, together with the carbon atom which they substitute, can also form a 2-oxo-tetrahydrofuryl ring,R.sup.3, R.sup.4, R.sup.5 and R.sup.6 can be identical or different and represent hydrogen, methyl, ethyl or n- or i-propyl andX represents hydrogen, halogen or nitro,or an acid addition salt, alkali metal salt, alkaline earth metal salt, heavy metal salt or hydrate thereof. The heavy metal salts are new.
