Gummosis is a common fungal disease that affects cherry trees. It is caused by the fungus Botryosphaeria dothidea and is characterized by the formation of gummy cankers on the tree’s trunk and branches. If left untreated, gummosis can lead to serious damage to the tree and even death. Fortunately, there are steps that can be taken to treat gummosis and protect the health of your cherry tree.
Identifying Gummosis
The first step to treating gummosis is to identify it. The most obvious sign of gummosis is the presence of gummy cankers on the trunk and branches of the tree. These cankers are usually dark in color and have a rough texture. They may also be oozing a sticky sap. In some cases, the cankers may be covered in a grey or white mold. Other signs of gummosis include discoloration of the leaves, wilting and defoliation.
Treating Gummosis
Once gummosis has been identified, it is important to take action to treat it. The first step is to prune away any affected branches or cankers. This will help to reduce the spread of the disease and prevent further damage to the tree. It is also important to disinfect any pruning tools before and after use to prevent the spread of the fungus.
Next, it is important to apply a fungicide to the infected areas. This will help to kill the fungus and prevent it from spreading further. Fungicides should be applied according to the instructions on the label.
Finally, it is important to keep the tree well-watered and mulched. This will help to keep the soil moist and discourage the growth of the fungus.
By following these steps, you can help to protect your cherry tree from gummosis. With proper care and treatment, you can help ensure that your cherry tree remains healthy and free from disease.
