#1: It is caused by a Fungus AND a Pest

First and foremost, you want to know what is thousand cankers disease?

This disease is unique in that it’s caused by the combined action of a disease and a pest. Thousand cankers disease is caused by the fungus-carrying Walnut Twig Beetle.

This pest is known to tunnel beneath the bark of walnut trees and create small cankers by spreading the fungus as the beetles feed inside the bark.

Over time, repeated attacks and growing cankers can start to cause serious trouble for your tree.

#2: Early Thousand Cankers Disease Symptoms Include Yellowing Leaves

Unfortunately, this disease can be difficult to diagnose since the problem is happening within the tree bark. Early thousand cankers disease symptoms are yellowing, wilting leaves…and sometimes dead limbs in the upper area of the tree.

Of course, those symptoms can be caused by other tree problems, which is why a professional diagnosis is important.

Unfortunately, in terms of its ability to do damage, it is the most lethal to the Black Walnut. In fact, since this disease was first discovered, it has caused the widespread death of many Black Walnuts across the country.

#4: There is No Cure for Thousand Cankers Disease

In terms of thousand cankers disease treatment, there is no cure for this disease. If your tree is determined to be infected, the best course of action is typically management of its overall health.

If your tree has not already been ravaged by disease, proper irrigation and fertilization can help maintain its overall health for the time being. 

If we come to see your tree after this disease has already taken an aggressive hold, it may be too late, leaving tree removal as your best option.

Tree disease does not always mean death and there are some diseases that have cures and treatments. But when death is imminent, it is safer to remove your tree than to take any risks that it could fall. 

While tree leaves that are black or falling off are an eyesore, disease that has progressed can also cause more serious problems such as decaying or dead tree limbs that pose a risk of falling. 

Even when it’s not that severe, some trees may never fully recover from being stricken with a disease, like thousand cankers. They may look sickly or aesthetically unappealing for the rest of their life, leading you to choose to remove them based on appearance, which is a reasonable decision.
