You can never “cure a mushroom tree”, but you can cause the fungus to go into remission when the tree regains its health and stamina. The treatment for apple scab consists of controlling the fungus and its spread by removing and raking dead and infected foliage. In the event of a serious infection, apply a fungicide at the beginning of the season to protect new leaves that emerge. The fungicide doesn't cure apple scab, but it can prevent further damage to a tree and nearby healthy plants.
Ultimately, however, prevention is the best option. To avoid disease, plant only disease-resistant varieties. The best way to treat most fungi is to call an arborist. It is difficult even for professionals to be able to identify fungi without sending samples to the laboratory.
Remember that the parts of the fungus that you can see are only the fruiting body. If it's not flourishing, there's no way to identify it without a lab. Apply fungicides to the tree at specific times for specific fungi. Fungicide labels include instructions for several types of fungal diseases.
In most cases, an application every seven days is recommended until the problem is resolved. Unfortunately, there is no cure for bacterial leaf scorch. Once the bacteria are present, the only option is proper management to delay death. This fungal disease deprives trees of their ability to effectively circulate water, so supplemental irrigation and mulching are a good start.
Be sure to monitor trees for signs of disease. Even diseases that are not fatal can severely weaken trees and cause damage that can last for years. Over time, an infected tree can also lose all its leaves, causing stress that can make the plant susceptible to other diseases. Before you start radiesthetizing your tree with fungicides and other chemical mixtures, you should identify what type of fungus is growing on your tree and if it can be safely eliminated.
Unfortunately, many of the fungal diseases that commonly affect trees in the DFW area cannot be treated and are deadly. In times of drought in DFW, you'll need to check your trees for signs of drought stress and potentially supplement all your trees with water. Preventive spraying with fungicides, liquid copper or biofungicides, especially if the disease is common in the area, can prevent spores from affecting apple trees. For larger cankers on a tree trunk, call a professional tree service to assess the extent of the damage and recommend a course of action to treat and save the tree or eliminate it.
The best (and sometimes the only) way to protect trees from fungal diseases is to prevent them through proper management and monitoring. Usually, when a tree is diagnosed with this fungal disease, the only step to take is the removal of the trees and the chemical treatment of the region. Whether you're worried that your tree is already infected or you're simply determined to keep your trees healthy, you've found the right place. The selection of trees and sites, irrigation during periods of drought and regular maintenance fertilization are the keys to maintaining the health of trees in the landscape.
However, it could also severely weaken trees over time, leaving them vulnerable to other disease and pest problems. Oral diseases can cause great damage to trees when they kill enough of the bark to surround a branch or trunk. Proper tree care will also require good pruning practices and proper wound care for any injuries the tree suffers. .
