Aliso Viejo Fungus
A large tree disease has recently hit California and is named “Aliso Viejo,” which is in the Santa Barbara area. The disease is called “Black spot” or “Fungal Spot.” This small white spot appears on a tree trunk and leaves, and grows slowly over several years. This infection is not always fatal, but if it advances too far, the affected tree may not survive. Fortunately, there are several treatments for “Black spots” in California.
A few decades ago, I had a friend who owned a coffee grove near Candlestick, California. She had dozens of trees and didn’t have a problem with the occasional infected tree. But one day, she noticed that one of her trees was completely destroyed, with the bark and leaves falling off – dead. Another tree close by also had large greenish black stains all over its leaves and bark. The infected trees were removed and taken to a hazardous waste dump, fortunately none of the trees suffered any damage.
Luckily, I knew of a local contractor who could take care of this problem right away. The contractor was experienced with “rotting out” trees. That’s when he first thought of contacting me. He was removing a tree when I showed up with an alarming question – Can you tell me more about these diseases?
He told me that Aliso Viejo can be a serious problem for any tree, particularly young ones, which are more susceptible to disease because they are growing out of the ground. These diseases often start on the lower twig tips but can eventually spread through the entire tree canopy, attacking the tree from the inside out. This is not a very pleasant sight. The first stage of the attack is usually slow, but once it begins, the growth rate of the affected tree slows dramatically, eventually leading to death.
Aliso Viejo is a broad term for an infective disease of all trunks and branches of trees. It usually begins in the lower twigs or needles, where it flourishes and spreads rapidly. If left unchecked, the pathogen can spread throughout the tree canopy, attacking other trees and causing die-off in the forest. This is why it is so important to get your trees treated as soon as possible. Tree diseases like Aliso Viejo are caused by fungi called Botryits camera, which feed on tree juices, sap and leaves. These fungi produce sugar from the tree juices, attaching themselves to the inner bark and eventually finding their way to the surface.
Aliso Viejo is one of the most difficult tree diseases to prevent. It first attacks the lower twigs or needles, which is the easiest target. This is followed by rapid growth at the trunk and tips, which weaken the tree even further. Since the fungi grow at a slower rate at the tips of the tree, it can quickly spread to the entire tree. When it eventually takes hold of the tree, there is little the tree can do to fight back, and in severe cases, the disease may be fatal.
There are a number of different treatment methods available for Aliso Viejo and other tree diseases. Some of the more traditional methods include using a commercial product, such as liner or proline bleach, which are applied directly to the infected areas. While these products can work to kill some of the fungal species responsible for Aliso Viejo, they often have limited effect or are simply used as a preventative measure. Other types of treatment include chemical fungicides, which may also be purchased over-the-counter, although these chemicals tend to be toxic and pose health risks when used. Most tree care professionals recommend that instead of treating with commercial products, it is best to seek the services of a professional tree doctor who can provide the appropriate treatment.
Once Aliso Viejo is properly diagnosed, the tree doctor will determine the most effective course of action for treatment. Sometimes, simply following the recommended treatment regime can save a tree, but if the tree is damaged beyond repair, the best course of action may be to remove it and replace it with a new one. This is usually not a difficult task, as trees are durable enough to withstand most types of treatment. If a tree has already been felled and a replacement is necessary, however, it is important to remember that a skilled arborist is the best person for this task. Not only will an arborist know the right way to cut a tree into proper pieces for installation into a building, he or she will also know exactly what chemicals should be applied to prevent future root rot and decay, as well as the pressure points in which the tree will likely break if it is damaged enough to cause such damage.
