Poisoning Conifers in Stand Improvement and Timber Sale Practice
Abstract:The use of sodium arsenite solutions to kill worthless low-grade ponderosa pine trees is described. Holes five-eighths inch in diameter are bored in tbe tree and filled with the solution. The diameter of the tree determines the number of holes required. Although the work has not gone far enough to warrant final conclusions, the indications are that trees killed in this manner do not create a serious insect hazard, nor is there sufficient poison to be dangerous in the wood or needles of the killed tree.
