Effects of postharvest treatments on recovery of Xanthomonas citri subsp. citri in infected grapefruit leaves

Studies were conducted to evaluate treatments that reduce recovery of Xanthomonas citri subsp. citri (Xcc) in infected grapefruit leaves. To investigate effects of temperature (0, 10, 40, and 50 °C), disinfectant (none or Pro-San), and treatment duration (0, 2, 10, and 20 min) on survival of Xcc in vitro, a split–split plot experimental design was utilized. Recovery of Xcc in vitro in the absence of Pro-San decreased with increasing treatment duration at 50 °C but not at temperatures
