▲Fig. 1. Tomato Bacterial Spot is caused by the bacteria Xanthomonas spp. It can be transmitted by animals, humans, insects, agricultural tools, soil particles, water pollution, and so on. When growing in the high-humidity environment with a temperature of 24-30 °C, tomato is the most susceptible to this disease, which damages plants and fruits, and affects fruit quality and yield in some severe cases.
