Evaluation of commercial volume losses to Pinus radiata caused by Dothistroma septospora under varying forest management and chemical control conditions in the province of Valdivia

Abstract

This study involves the physical and economic evaluation of varying situations within silviculture schemes in which a chemical control for Dothistroma is applied in a Pinus radiata trial. The trial examined several management and control methods. The objective was to evaluate the efficiency of these methods in limiting damage caused by Dothistroma in the context of overall practical and economic effectiveness. The results indicate that chemical control was effective, but the higher costs involved meant that they exceeded the value of the recovered volume of timber.
