Abstract：The inhibitory effects of 1 3 agrochemicals against Ralstonia solanacearum were detected by agar cup -plate method in the laboratory.The results showed that 6 agrochemicals,3% tetramycin aqueous solution,72% streptomycin soluble powder,80% ethylicin emulsifiable concentrate,80% thiram water dis-persible granule,3% zhongshengmycin wettable powder and 75% cholrothalonil·myclobutanil wettable pow-der,all showed effective antibacterial activities.Among which,3% tetramycin aqueous solution had the best inhibitory effect with the inhibition zone diameter of 1 9.1 0 mm.The inhibition zone diameters of 6 agrochemi-cals increased with the increase of concentration.The combinations of 3% tetramycin aqueous solution with 72% streptomycin soluble powder,3% tetramycin aqueous solution with 3% zhongshengmycin wettable pow-der,and 3% tetramycin aqueous solution with 80% thiram water dispersible granule showed the best inhibito-ry effects with the inhibition zone diameters of 1 9.20,1 8.33 mm and 1 7.73 mm respectively.The inhibitory effects of combinations were superior to single agrochemical.
