WP101-PRO® wood preservative paste. Developed and produced by Poles, Inc. for the use as a ground-line treatment for standing utility poles. WP101-PRO® contains the same Disodium Tetraborate Decahydrate diffusible wood preservative ingredient as other leading wood preservative paste, plus the addition of two highly effective azole preservatives. The three active ingredients combine to effectively prevent fungal and insect attack from destroying the strength of the ground-line area of in service wooden utility poles.
