Some Internal Effects of Mauget Tree Injections

Abstract

Negligible amounts of discolored wood and cambial dieback were associated with control Mauget injection wounds (no chemicals added) made 1 year earlier on red maple, white oak, and shagbark hickory. Columns of discolored wood and some cambial dieback were associated with wounds that had been injected with Bidrin or Meta­ Systox•R. Columns of discolored wood and very little cambial dieback were associated with wounds that had been injected with Fungisol or Stemix. Injured tissues associated with all wounds were compartmentalized in the wood present at the time of injection; wood that formed subsequently was not infected.
