Jasmine Plant Diseases

Jasmine is a flowering plant. Its blossoms are beautiful and they emit a delicate fragrance that is often extracted as an essential oil. If well watered and fertilized, jasmine is easy to grow in a home flower garden. But while relatively hardy, jasmine is susceptible to a few diseases.

Leaf Blight

Jasmine plants affected with leaf blight develop red-brown circular spots on their upper surface. The infection spreads rapidly, especially during the rainy season. And as it progresses, infected leaves curl and dry at the margins. In severe cases shoots, buds and young branches dry out as well. Leaf blight severely reduces flower production, but is not dangerous. Spray affected plants with bordeaux mixture to control the disease. According to the University of California's Integrated Pest Management Program, bordeaux mixture is a fungicide and bactericide that has been used for decades to control diseases of tree fruits and nuts, vine fruits, and ornamentals.


Rust affects all parts of the jasmine plant, coloring it with yellow-orange pustules. As the disease progresses, infected plant parts become distorted. To control rust, prune affected tissue and follow with a copper or sulfur spray.


Jasmine plants affected with this disease wilt in sections. Wilt slowly kills the root system of the jasmine, starving the plant of essential nutrients. Uprooted jasmine plants with wilt show roots that are blackened in patches and girdled with the white mycelia that causes the disease. To kill wilt, treat the soil with bordeaux mixture.
