In this month’s Blog post we discuss the importance of Tree Diseases Treatment. Just like humans, trees can sometimes have problems with their health. In the same way that our health complaints can vary from the mild to the severe, the same is true with trees.
Tree diseases also vary in how commonly they occur.
This Blog post will discuss some of the more common ailments your trees might have and tree diseases treatment. For how to recognize them, and what to do about them. It is first important to understand why trees get sick. The cause is not always obvious and in some cases is hard to pinpoint.
Quite often, however, trees show signs of dysfunction due to causes in their local environment. This could be due to such things as changes in available water, root damage or disturbance. Soil compaction, contamination or poisoning, and sun scorch.
Diseases or pathogens naturally occur in the environment.
It is normal and common for trees to exist alongside and have low levels of many pathogens present at any one time.
Changes in the local environment, such as those mentioned in the second paragraph, can stress trees lowering their defenses against pathogens. If the stress factors continue uninterrupted, they can lead to strain. Where the tree will exhibit advanced stages of disfunction, with parts or all the tree dying.
Different diseases in trees will present with varying symptoms. I will provide links to useful resources at the end of this Blog post for identifying specific pathogens. However, more general signs that a tree is unwell include the following. Discoloration in the foliage, spots on the leaves, distorted leaves and a thin canopy. Also dead/dying leaves, dead/dying branches, fungal fruiting bodies (mushrooms) on or around the tree, aphids/insect larvae.
Tree diseases treatment signs
Signs to look for in the environment that could be stressing a tree are water logging, cracked and dry soil. Recent earth works, exposed or damaged roots, strong smells of fuel or other contaminants. Also new buildings or construction near the tree.
To help a stressed tree it is important to know what is causing the disfunction. So that you can address the core of the problem rather than treating the symptoms. You can use the resources at the end of this Blog post to identify the disease. Then use that to trace what is the likely stress factor in your situation.
Finally, you can mediate this factor as best as possible.
To hopefully create a situation where the tree can heal itself. Some disease can be treated with chemical applications. However, it is always best to address the root cause too otherwise it is likely to reoccur.
Before supplying links to common tree diseases treatment, there are two that I would like to focus on. There are two that are important for our Auckland region; Kauri dieback and Myrtle rust.
Kauri dieback is a disease caused by a microscopic fungus-like organism, called Phytophthora agathidicida (PA). It lives in the soil and infects kauri roots. Causing damage to the tissues that carry nutrients and water within the tree, effectively starving it to death. There’s currently no proven cure or treatment and nearly all infected kauri die.kauridieback.co.nz
Myrtle rust is a fungal disease caused by the fungus Austropuccinia psidii that only affects plants in the myrtle family. New Zealand has a variety of native plants that belong to this family. Including pohutukawa, manuka, kanuka, rata, swamp maire and ramarama.
When a plant becomes infected with myrtle rust, the disease affects the young, soft, actively growing leaves, shoot tips and young stems.myrtlerust.og.nz
