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 in moisture-prone areas in your garden. This is a fungal infection of the trees, caused by the pathogen Gymnosporangium globosum. It mostly attacks the Hawthorn and Junipers. It is essential to perform spring tree care because the fungus infects the tree, 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, and find a new host after regular intervals. (Like it can move to the Junipers in your garden from the Hawthorns). As these fungi 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, and quince trees as well.
In early spring, it spends parasitizes 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 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 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 turn to orange color and have black dots in the center of the lesion. Aesia, more popularly known as cluster cups, is 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.
Cedar Hawthorn Rust Treatment
Our experienced professionals at North Texas Trees help you in preventing Cedar- Hawthorne rust in your garden. The curing procedure for once-affected plants is not as simple as the rust is persistent and very much pestiferous. Contact us as soon as you see the galls in your Hawthornes for spring tree care (specifically in winter and early spring). Our texas tree surgeons make sure that they remove all appropriate galls from the foliage.
Sometimes, it is necessary to remove an entire branch to save the rest of the tree. We remove infected twigs and fruits as much as possible without harming the non-infected ones. Susceptible Junipers are challenging to avoid growing near the Hawthorne trees. And spores produced in galls can spread as much as 15 miles away from the source to infect the Hawthornes. We ensure the air circulates freely through the risk-prone plant areas to reduce moisture.
How Texas Tree Surgeons of NorthTexasTrees Can Protect Your Trees from Cedar Hawthorn Rust
For future advancement, we plant Cedar Hawthorne-resistant juniper varieties. These are the precautionary measures we can take before the fungus is spread all over your garden trees. For proper cure and maintenance, the North Texas Trees crew usually applies fungicides when the Juniper’s galls start producing gelatinous cones. 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 Juniper’s infection, we may use the Bordeaux mixture during the mid-summer.
