Abstract:

Screening effective bactericides to Xanthomonas axonopodis pv. citri is the main measure to control Citrus Canker. Toxicity test showed that EC50 of 70% Cupic Hydroxide WP, 20% Thiodiazole-copper SC, 3% Zhongshengmycin WP, 77% Dodecylguanidine monoacetate WP, 72% Streptomycin Sulfate to Xanthomonas axonopodis pv. citri were 265.71, 93.86, 162.89, 127.61, 38.62 μg/mL, respectively. According to EC50, the sequence of inhabitability to Xanthomonas axonopodis pv. citri were 72% Streptomycin Sulfate > 20% Thiodiazole-copper SC > 77% Dodecylguanidine monoacetate WP > 3% Zhongshengmycin WP > 70% Cupic Hydroxide W P.
