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, and R.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, or R.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 and X 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.
一种对抗植物病原细菌的方法,包括向细菌或细菌栖息地施加有效杀菌作用的环丙基-1,4-二氢-4-氧-3-喹啉羧酸衍生物,其化学结构如下:其中A代表直链或支链烷基,含有1至6个碳原子,或>C=CH-基团,R1代表含有1至6个碳原子的烷基部分的烷氧羰基,苄氧羰基,羧基,可选择性取代的氨基甲酰基,氰基或含有1至4个碳原子的烷基磺酰基,R2代表氢,含有1至6个碳原子的烷基部分的烷氧羰基,苄氧羰基,可选择性取代的氨基甲酰基,氰基,氯,乙酰基,含有1至3个碳原子的烷基或苯基,或R1和R2,连同它们替代的碳原子,也可以形成2-氧代-四氢呋喃基环,R3,R4,R5和R6可以相同或不同,并且代表氢,甲基,乙基或n-或i-丙基,X代表氢,卤素或硝基,或其酸加合物盐,碱金属盐,碱土金属盐,重金属盐或水合物。这些重金属盐是新的。
