There were tested seven bactericides (S-0208, Kocide 101, Champion 50 WP, Kuprikol 50, Sandofan C, Curzate K, Trimiltox forte), two fungicides with bactericidal effect (Aliette, Ridomil Plus 48 WP) and antibiotics (Streptomycin) against bacteria of genera Erwinia, Pseudomonas, Xanthomonas, Corynebacterium, Agrobacterium and Flavobacterium in vitro. The antimicrobial activity of bactericides was shown on agar plates contaminated by indicator bacterium. The most efficient was the preparation S-0208 (oxanilic acid analogue). Bactericides as Trimiltox forte (mancozeb, Cu), Kuprikol 50 (oxychloride Cu) and Streptomycin (streptomycin sulfate) showed half efficacy related to the preparations S-0208 and Champion 50 WP (hydroxide Cu) and Kocide 101 (hydroxide Cu) cca 1/3 efficacy related to the preparation S-0208. Sandofan C (oxadyxil, oxychloride Cu) and Curzate K (cymoxanil, oxychloride Cu) were weakly effective. Aliette (fosetyl Al) and Ridomil Plus 48 WP (methalaxyl, oxychloride Cu) were evaluated as ineffective.
