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.

Longleaf pine (Pinus palustris) is a pyrophile, depending on fire to clear the ground for seed germination. [4] The passage of fire, by increasing temperature and releasing smoke, is necessary to raise seeds dormancy of pyrophile plants such as Cistus and Byblis an Australian passive carnivorous plant. Imperata cylindrica is a plant of Papua ...

The disease can affect every part of the tree, from the fruit to the trunk. [14] Infected trees may die within months or can linger for years with severely reduced yields. In addition to the scorched appearance of the plant parts that gives the disease its name, plant tissues infected with the bacteria will exude milky or reddish-brown ooze.
Trees can be planted on resistant rootstocks to ward off the effects of the blight. As the blight rarely kills trees, it is possible for an infected tree to produce years of profitable yields before the blight renders it uneconomical; for this reason, some sources recommend that citrus trees be planted on nonresistant but high-production ...
Although chemical control can be effective, cultural management is the most common method of control for this disease. Cultural management for Eastern Filbert Blight involves scouting orchards, pruning and removing cankers, and removing plant debris from the ground. Orchards should be scouted thoroughly twice per year to remove cankers.
Removing blighted trees to control the disease was first attempted when the blight was discovered, but this proved to be an ineffective solution. Scientists then set out to introduce a hyperparasitic hypovirus into the chestnut blight fungus. The trees infected with virus-treated fungus responded immediately and began to heal over their cankers.
