Mesquite Tree Leaves Turning Brown And Stale – What Is It?

The first thing you need to do is check if your trees are suffering from signs of mesquite tree sickness (STS). STS is a type of leaf spot disease caused by the fungus Phytophthora ramorum. This fungal infection causes yellowing and browning of leaves. If left untreated, it can cause death within just one year. The symptoms include:

  • Yellowing of leaves, stems and twigs.
  • Brown spots or blotches on the surface of the leaves.
  • Leaves may turn brown and shrivel up.

If you see any of these symptoms, then your trees are infected with mesquite tree sickness (STS) and you need to take immediate action to treat them immediately!

How To Get Rid Of Mesquite Bug Borers?

There are several ways to kill the mesquite bug borer. Some methods are mechanical while others involve chemicals. There is no sure way to eliminate the problem completely, but there are certain things you can try before resorting to chemical treatments. You will want to consult a professional arborist for advice on which method would work best for your situation.

Control the Spread of the Disease

If you have one or two trees that are affected by STS, there are some steps you can take to limit the spread of the disease. The most important thing is to make sure the fungus is not transferred from tree to tree. This means you should not move tools, equipment, clothing, or anything else that comes in contact with an infected tree to a healthy tree. You should also make sure to clean your tools and equipment before moving from one tree to another.

Furthermore, you should avoid moving infected plant material such as nuts, seeds, or even roots from an infected tree to a healthy one. You can dispose of STS-infected plant material on site so it does not spread to other trees.

Proper Pruning of the Trees

Pruning the trees correctly is also important. If you already have a professional tree trimming company that is aware of the problem, then you should let them know about the infection and ask them to take care of the problem correctly. However, if you do not have a professional company that takes care of your trees, then you might need to hire one since proper pruning is incredibly important when it comes to tree health problems. It would be best to ask an arborist for help in this matter.

In addition to pruning, there are other maintenance tasks that need to be done such as clearing away dead wood and removing weeds and other debris near the base of the tree. This will not only reduce the amount of clutter around the base, but will also improve airflow which will help prevent various tree problems from occurring.

Finally, you can also treat the trees with insecticides if you want to kill the female mesquite tree borer. This will help keep new populations from forming, but it will not directly help the trees that are already infected with STS. You should never use a full-strength insecticide since it can cause damage to the tree. It is best to consult a professional arborist before employing this method.

Mesquite Tree Borer For Removing Mesquite Trees

Finally, you can call in the pros and get rid of the trees altogether. This is actually the most cost-effective solution since it does not involve ongoing expenses and you will not have to spend time or effort taking care of the trees. There are a few different companies that will do this for you such as Mesquite Tree Borer. They will come to your property and drill into the trees and fill them with an insecticide that will kill the borer.

The trees will eventually die, but it will take some time. After the tree dies, they will come back and cut it down for you and remove it from your property.
