Abstract
Development of bacterial spot on Suwanee peach leaves after inoculation with Xanthomonas campestris pv. pruni was studied at 24 and 30°C and after-inoculation wetness periods of 0, 6, 18, 24, and 48 h. Water congestion following leaf wetness resulting from exposure to 100% relative humidity for at least 36 h and growing plants in sandy soil were necessary for symptom development. Symptom development was slower at 24 than at 30°C. Postinoculation wetness periods greater than 18 h were necessary for extensive symptom development at 24 but not at 30°C. However, some symptom development was evident at either temperature with no leaf wetness after inoculation if leaves were water-congested. Symptoms did not develop when trees were grown in a sandy loam-vermiculite soil mixture.
