Paraformaldehyde Pills - Paraformaldehyde pills are used by the maple tapping industry to kill contact parenchyma cells. They are placed in the tap holes thus stalling vessel plugging and sap flows longer. Decay-causing fungi love it! I hear that many over-tapped and pill-treated trees die from acid rain. And there is much more. For more, see the paper listed under SHIGO 2002 CD's "MAPLES - 03 PILL PAPER, TAPPING".
