FAQ

Is Arborbiotic injected into the root collar or trunk flare? I understand annual injections may not fully control fire blight in Callery 'Redspire' pears despite using Forti Phite plus calcium, and infected branches need pruning six inches back with sterilized tools. Is this correct?

Arborbiotic is injected in the root flair area of each tree. You are correct in that treatment may not be 100% effective, but reduces the spread of the blight. This treatment will need to be considered on an annual basis to be effective. We have had great results at Delaware Park with an annual injection treatment to 136 'Chanticleer ' Pears. The recommended soil care programme does not need to be completed annually. Pruning of the infected branches is a good idea as you outline. Our research has shown that sterilizing is not required after each cut, however.
