What is Cedar Hawthorn Rust?

Cedar hawthorn rust is the most common phenomenon of all Dallas tree diseases that occurs mostly in mid-summer or spring. It attacks the plants of moisture-prone areas in your garden. This is a fungal infection to the trees, caused by the pathogen Gymnosporangium globosum. It mostly attacks the Hawthorn and Junipers. It is essential to perform spring tree care as once a tree is attacked by the fungus, it can rarely recover from the damage.

How Cedar Hawthorn Rust Affects Your Texas Trees

The moist environment helps the fungus to grow. Usually, it travels from one tree to another to survive, find a new host after regular intervals. (Like it can move to the Junipers in your garden from the Hawthorns). As these fungus come from a very resistant species, it is almost impossible to get rid of them once they get a grip on your precious greeneries.

This plant pathogen is a heteroecious rust fungus meaning it requires a minimum of two hosts to complete its life cycle. In the primary stages of the life cycle, the pathogens infect eastern red cedar, rocky mountain juniper, and other common junipers in your garden. At the same time, the latter is prone to affect Hawthorne, Apple, and sometimes the Pear, Quince trees as well.

In early spring, it spends parasitizing in the primary host plant, and mid-summer releases spores from the telia, which occurs in the secondary host plant. You can see yellow or orange drying brown and black in the leaves of the plants. Spores from the junipers travel through air or water during the early morning or midnight time. If the landing spot is wet and moist, as mentioned earlier, the spores easily penetrate them.

Symptoms of Cedar Hawthorn Rust

Cedar Hawthorn rust infects fruits and green sprouts, distorting the growth to some extent. You can see bright yellow or orangish spots on Hawthorn Apple leaves during summer. If leaves are infected heavily, they may desiccate, drop prematurely, and turn on deciduous trees and shrubs. The pathogen-infected Junipers develop small roundish galls (1/8 to 9/16 inches in diameter), which slowly grow onto twigs and are reddish-brown in color. Cedar-hawthorn rust galls may often cause the death of infected evergreen sprigs. Small yellow spots are seen in Junipers in the early days of infection, which later turns to orange color and has black dots in the center of the lesion. Aesia, or more popularly known as cluster cups, are produced 80 to 90 days after infection. Hawthorne fruits may also exhibit rust-colored fingers. During the rainy days of spring, these galls expand into gelatinous cones. However, the symptoms may vary in different hosts.

Chlorothalonil and mancozeb are verified to be used as fungicides for Hawthorne. We begin spraying when the buds begin to break open and repeat at regular intervals until the petals fall. We do not risk spraying fungicides in the Junipers directly because it causes visible damage to the plants. Spring and early summer is the perfect time for applying fungicides. For the Junipers infection, we may use the Bordeaux mixture during the mid-summer.
