How to treat fire blight on apples?

OSU recommends the following treatment protocol: For apples, apply lime sulfur when your tree is at 20% and 70% bloom; then follow it up during full bloom through petal fall with Serenade. For pears, only use the Serenade, and apply at the same time as for apples. This protocol has yielded similar results as conventional treatments in field studies. Copper can help control the spread of fire blight if applied during bloom, every four to five days until blooming is over. This can cause russeting or scarring of fruits, but can be effective in preventing the disease from spreading during the most active season of its lifecycle. However, copper cannot eliminate infections that are already living in the wood. Its primary purpose is to make a bacteria-killing barrier on the surface of the tree to prevent the spread of infection to new areas. (Copper is not an organic pesticide: if you are a certified producer, speak to your certifier before applying this or any other product).

When other options have failed, you can treat fire blight with a commercial bactericide containing streptomycin. Mix at a rate of 1 tablespoon per 2 1/2 gallons of water, and spray leaves and blossoms every four to five days during the blooming season. While it's technically safe for use, streptomycin has antibiotic properties in humans and may cause skin irritation, so it should not be used as a first treatment option in home landscaping.
