compound applied to tree wounds or pruning cuts.

wound dressing (Wikipedia)

A dressing or compress is a sterile pad applied to a wound to promote healing and protect the wound from further harm. A dressing is designed to be in direct contact with the wound, as distinguished from a bandage, which is most often used to hold a dressing in place. Many modern dressings are self-adhesive.
