Fumigants Can Stop Internal Decay of Douglas-Fir Poles for At Least 5 Years
To stop internal decay of Douglas-fir transmission poles pressure-treated with pentachlorophenol in heavy oil, two pints of agricultural fumigants (chloropicrin, Vapam, or Vorlex) were placed in 7 holes within 3 […]

Fungal discoloration of kiln- and air-dried Scots pine lumber in aboveground testing and its assessment by digital image processing
Redistribution of water-soluble sugars and nitrogenous compounds by drying increases the nutrient content of the lumber surface. Kiln- and air-drying cause different redistribution of the soluble sugars and nitrogen and […]
