How do you get rid of tree disease?

Fire blight usually affects apple and pear trees. The bacterial infection attacks flowers to begin with and eventually causes cankers and sprouts that wither quickly. As with other types of plague, there is no cure for the fire plague. To prevent the spread of the disease, get rid of cankers when the plant is inactive.

Pruning affected stems and branches also helps control them. Bacterial sprays can help prevent bacteria from surviving and spreading. Even so, there is no guarantee that spraying the tree with chemicals will solve the problem. If an inspection shows that your tree still has plenty of opportunities to thrive in the coming years, we'll approach the problem from two angles.

First, we will work to eliminate or contain the infection by pruning and antifungal treatments of trees. Second, we strengthen the tree's health so that your own immune system can also fight the tree's fungal infection. Use a fungicide containing the active ingredient Fenarimol. It is not necessary to remove infected leaves, as the fungicide will kill the fungus and return the leaves and the tree to their former glory.

You must carefully remove and dispose of infected fruit. To control the spread of Armillaria root rot, remove dead trees and as many of their roots as possible. If the plant has recently been infected, expose its base to air for several centimeters, removing 3 to 4 inches of soil. In colder temperatures (before freezing), recover exposed roots with loose soil.

Bacterial or viral infections tend to affect trees when trees have suffered a pest or significant climate damage. The tree should be sprayed as soon as the leaves emerge from the tree and again once the leaves are fully developed. Tree disease control is one of the main activities of forestry, as forests suffer from multiple pathogens, nutrient deficiencies and pest invasions. Over time, an infected tree can also lose all its leaves, causing stress that can make the plant susceptible to other diseases.

As the season progresses, fungal spores from the apple tree return to junipers and red cedars, where a new infection occurs. Needle spread often occurs from the base of the tree upwards, and the lower branches of the tree die first as the infection progresses. When a tree is infected with brown rot, flower blight, the symptoms of the disease will begin to appear in the spring shortly after blooming. If you look at the branches of your citrus tree and they seem to be swelling, it is likely that the tree has been infected by a citrus wasp.

In spring, spray the tree with the Captan ornamental tree fungicide Fruit & or the multi-purpose fungicide Fungi Max. Preventive spraying with fungicides, liquid copper or biofungicides, especially if the disease is common in the area, can prevent spores from affecting apple trees. If your tree dies, it is recommended that you remove the dead tree, as it becomes unstable quite quickly. If a palm tree is already showing symptoms of palm yolk rot, treat it immediately with a liquid copper fungicide, focusing the greatest attention on the terminal bud.

Verticillium wilt, often called maple wilt when it affects maple trees, is a very common disease that attacks a large number of trees. It damages tree roots and root hairs, but can only be detected when visible on the top of the tree. Black spot disease appears on the leaves of trees and shrubs as small circular black spots that range in size from approximately ¼ inch to 1 inch in diameter. Most infections from hardwood species are also caused by fungi, with no specific treatment for tree diseases.
