How do I Control Fire Blight?

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.

Shortly after bud break, spray the tree with Agri-Fos Systemic Fungicide, ensuring thorough coverage. To improve the binding and penetration for the fungicide applied it with Nature's Own Spray Helper or Pentra-Bark (call for details). Repeat the spray at one to two month intervals, more frequently in high disease situations.

Prune out infected branches. The point of pruning must be 12 to 16 inches beyond the last visible signs of the disease on the branch. 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.
