How to prevent and treat jasmine branch blight

Symptoms and characteristics of jasmine branch blight

Branch dieback is a common disease of jasmine. It is caused by improper maintenance of the plants, which leads to the outbreak of fungal diseases. The pathogen spores gradually spread through wind and rain and grow in low-lying areas with heavy soil and lack of fertilizer and water. Areas with poor growth are extremely prone to the disease.

In the early stage of the disease, the growth trend of the plant gradually weakens, and the color of the branches changes from yellow-green to dark red or brown. In the later stage, it gradually turns white, the branches dry up, and many small black spots appear.
