Unfortunately, while chemicals and meticulous pruning can keep an infected tree productive, there is no known comprehensive cure for fire blight; the best that can be done is to prevent its spread by measures such as avoidance of overhead water systems, as falling water can spread the disease and the careful pruning of tainted stems or branches.
While fire blight has always been a concern in eastern apple production, severe outbreaks in the west in recent years have caused growers there to adopt more consistent and vigorous monitoring and management programs as well. [23] The disease can affect every part of the tree, from the fruit to the trunk. [14]

Studying the surviving trees from stands affected by pests and disease is a very different approach from the way arborists of the early 20th century handled the chestnut blight that arrived with ...
The European chestnut (Castanea sativa) is also susceptible, but due to widespread CHV1 hypovirulence, blight-induced tree death is less common. [7] The fungus can infect other tree species such as oaks, red maples, staghorn sumacs, and shagbark hickories. [8] Once infected, these trees' bark also exhibit orange cankers but may not die.
Trunk injection or endotherapy also known as vegetative endotherapy, [1] [2] [3] is a method of target-precise application of pesticides, [4] [5] [6] plant resistance activators, [7] or fertilizers [8] into the xylem vascular tissue of a tree with the purpose of protecting the tree from pests, or to inject nutrients to correct for nutrient deficiencies.
