Figures
- Figure 1.
Sap exuding (“bleeding”) from elm wound one year following injection with TBZ.
- Figure 2.
Section from an elm one year after treatment with TBZ. The treatment-initiated discolored wood has merged with discolored wood present before injection
- Figure 3.
Section from a water-treated elm showing three discrete areas of discolored wood.
- Figure 4.
Cross section of a TBZ-treated tree. Columns have coalesced to cover nearly the entire cross section.
- Figure 5.
Radial section at the injection site from a tree injected 16 months earlier. Clear sapwood (left) produced after wounding, treatment-initiated discolored wood (center), and wood internal to the treatment-initiated discolored wood (right) and be seen clearly.

a Some wounds expressed more than one symptom, so that the number of conditions observed may exceed the total number of wounds.
