Chemical induction of resinosis in southern pines. Final report
Research studies in the use of paraquat, a contact herbicide, for lightwood induction; i.e., the accumulation of oleoresin in the boles of living southern pine trees are summarized. The objectives of this research were to determine oleoresin yields as influenced by treatment factors, to estimate treatment costs, to uncover technical problems, both in the field and processng plants, and to assess the problem of bark beetle attacks on treated trees. Two pulp and paper mill trials using paraquat-treated wood were conducted, one with loblolly and one with slash pine. The loblolly trial yielded 40 percent more tall oil, or an extra 27.2 pounds/cord of wood. Due to limited turpentine condenser capacity, no additional turpentine was recovered. However, there is evidence to believe that an additional one gal./cord could have been realized.
