Reaction of avocado wood on injections into the trunk

Sealing holes after injection of air or water did not decrease damage caused to avocado wood. The un-neutralized solutions of a 10%, as well as a 15% H3PO3 injection tended to cause less damage than the neutralized solutions while unneutralized and neutralized solutions of a 20% H3PO3 injection caused similar levels of damage. Addition of ZnSO4 or Solubor alone did not increase the damage to the wood. Although avocado wood seems to have the ability to heal and form new functional wood where damage, due to injections occurred, minimum injections necessary to maintain tree health should be used in order to minimise damage to wood over the long term.
