For areas below 400 meters above sea level, broad-spectrum fungicides, such as carbendazim and copper sulfate, are commonly used. For areas above 400 meters above sea level, the weather is colder, and the cold climate is easy to reduce the immunity of trees. At this time, it is best to use potassium permanganate and spray it on the trunk in cold weather to enhance the immunity of trees and prevent freezing injury.

If Sophora japonica is infected by fungi, bacteria or viruses, appropriate specific drugs can be selected for treatment. For example, Sophora japonica infected with powdery mildew can be treated with anti-oxygen white powder or triadimefon wettable powder, and at the same time, the spraying amount and application interval should be correctly controlled to avoid the negative effects caused by overdose.
