Symptom Identification and Control Methods of Walnut Bacterial Blight
1. Distribution and Occurrence Characteristics Widely distributed in walnut-producing areas such as Hebei, Shandong, Shanxi, Liaoning, Henan, Jiangsu, Zhejiang, Sichuan, Yunnan, Shanxi, and Gansu, with severe incidence in some areas.

The pathogen can infect floral organs, so pollen can also carry the bacteria, and insects are also vectors. The bacteria invade through stomata, lenticels, nectaries, and various wounds.
