Tools should be sterilized in an alcohol solution containing three parts denatured alcohol to one part water.

Special attention should also be given to garden tools, especially those that have been exposed to the bacteria. It may also help to avoid overhead irrigation, as water splashing is one of the most common ways to spread the infection. Unfortunately, there is no cure for fire blight, therefore, the best fire blight remedies are regular pruning and removal of any infected stems or branches. The maximum risk of exposure to this bacterium is late spring or early summer as it emerges from dormancy. Fire Blight Remediesįire blight bacteria is easily spread through various means such as rain or water splashing, insects and birds, other infected plants, and unclean gardening tools. These discolored oozing patches contain masses of the fire blight bacteria and heavy infections can be fatal. In more advanced cases of fire blight infection, cankers begin to form on branches. The flowers turn brown and wilt and twigs shrivel and blacken, often curling at the ends. This ooze begins to turn darker after exposure to air, leaving dark streaks on the branches or trunks.įire blight infections often move into twigs and branches from infected blossoms. The first sign of fire blight is a light tan to reddish, watery ooze coming from the infected branch, twig, or trunk cankers. The symptoms of fire blight can appear as soon as trees and shrubs begin their active growth. Fire blight gets its name from the burnt appearance of affected blossoms and twigs. The plant disease fire blight is oftentimes influenced by seasonal weather and generally attacks the plant’s blossoms, gradually moving to the twigs and then the branches. It is critical that the pruning tools be sanitized after each branch is pruned, so as to prevent spreading the disease form branch to branch.While there are numerous diseases affecting plants, the plant disease fire blight, which is caused by bacteria ( Erwinia amylovora), affects trees and shrubs in orchards, nurseries, and landscape plantings, therefore, no one is safe from its path.

The point of pruning must be 12 to 16 inches beyond the last visible signs of the disease on the branch. Repeat the spray at one to two month intervals, more frequently in high disease situations. To improve the binding and penetration for the fungicide applied it with Nature's Own Spray Helper or Pentra-Bark (call for details). Shortly after bud break, spray the tree with Agri-Fos Systemic Fungicide, ensuring thorough coverage. To control or prevent fire blight, in the early spring, before bud break, spray the tree with Liquid Copper Fungicide to reduce or eliminate any bacterial spores that are overwintering on the bark. Recommended Steps to Control Fire Blight: If left untreated, Fire Blight will gradually infect the entire tree, block the tree’s vascular system and kill it. As the branch is infected, the leaves begin to brown and blacken and appear almost burnt, hence the name fire blight.Īs the disease advances and the fungus reproduces, it begins to block the tree’s vascular system and causes branch die back or cankers to develop as the bacteria expands and “bursts out” of the tree’s bark. Once the blossom or leaf is infected, the bacteria spreads quickly throughout new tender growth, but slows as it reaches more mature woody growth. Trees are very vulnerable to Fire Blight infections immediately after heavy rains or hail storms where leaf tissue is exposed from rips and physical damage. During the damp spring period the disease is spread by rain, improper pruning and insects such as honeybees which transmit the bacterial infection from blossom to blossom. The bacteria overwinters on or under infected bark and in the early spring begins to ooze out. It is most prevalent on the following trees: apple, pear, hawthorn, cotoneaster, firethorn and mountain ash. Fire Blight is a bacterial infection caused by the Erwinia amylovora bacteria.
