Answer 2

Trees, like any other living thing, are susceptible to diseases. Some of the diseases encountered in trees are merely unsightly whereas others can reduce productivity or kill the tree.

When the defenses against disease are compromised, the disease can gain a foothold in the tree resulting in infection and sometimes in tree death.

What causes stress in trees?

Many environmental factors can cause a tree to be stressed.

•Drought, overcrowding, and damage to stem or roots are the most common causes.

Stem damage invites infection by creating points of entry for pathogens.

•Root damage creates points of entry for pathogens and reduces the trees ability to collect water which puts the tree under stress, thus making it more susceptible to infection.

•Drought, whether from lack of rainfall, from overcrowding, or from root damage; reduces the ability of a tree to isolate infections and prevent their spread through the tree.

Good tree management reduces drought stress and mechanical damage and thus reduces the likelihood of disease problems with trees.
