Japanese Black Bark Disease (JSBD):

Japanese Black Bark Disease (JBBD):

The Japanese Black BARK disease is caused by a fungus called Myxomycetes, which grows on the bark of trees. The fungus causes the blackening or peeling off of the bark.

The fungus usually affects young trees, but it can affect older ones too. JSBD is one of the most common and severe forms of Japanese Black Bark Disease. It’s not uncommon for trees to have several patches of blackened bark, even after they’ve been pruned back to bare branches.

The JBDB website states that “the disease is spread from infected trees through direct contact with infected wood.” Trees are most likely to get infected when they’re growing near each other.

There are two ways that trees can become infected:

When a branch breaks off and touches another tree, the fungus spreads from tree to tree. When a branch falls onto another tree, the fungus may travel up into the trunk of the fallen branch and infect nearby trees.

Infected trees often die within months of infection. If left untreated, JSBD will kill your trees if left unchecked.

Trees under stress are more susceptible to the infection, such as trees that don’t get enough nutrients. For this reason it’s important to maintain your trees.

The removal of dead wood and other weak branches will help prevent infection.

Trees may also be protected with a solution of 1 part chlorine bleach and 10 parts water. This should be applied once a month to the areas that are affected.

The JBDB website also states that “fungicides are of limited use in treating and preventing infection. Research has found that certain types of fungicides protect trees for up to four months.”

You should check your trees at least monthly and prune any dead branches. If you notice any discoloration or blackening of the bark, you should contact a professional arborist immediately.

Black Spots On Maple Tree Bark:

Black spots on maple tree bark can be caused by several different factors. It is not uncommon for maples to get black spots on their bark.

For example, black spot on the bark can be caused by environmental conditions such as extreme pollution and disease. Other conditions that can lead to the appearance of black spots on the bark are improper nutrition, injury and abrasion. They may also be caused by insects or fungus attack.

The good news is that black spots on the bark are not a cause for concern and do not affect the health of the tree as a whole. If you want to get rid of the spots all you need to do is wipe them off with a cloth dampened with a little bit of water.

Avoid using chemical solutions as these could potentially damage the bark and lead to problems in the future.
