Book Description
Silvicultural treatments as a method of preventing or reducing the intensification of dwarf mistletoe were evaluated. From 1967 to 1977, 23 plots in young lodgepole pine stands were sanitized by cutting or pruning the infected trees, with retreatment and assessment at 3-year intervals, and subsequent responses by the trees and the disease were recorded. The average percentage of trees infected gradually increased from 45 to 68% (+23%) on the infected, untreated plots, while decreasing from 42 to 37% (-5%) with a thinning and pruning treatment and from 52 to 18% (-34%) when complete eradication was attempted. Comparable changes in average stand infection ratings were +0.62, -0.08 and -0.64, respectively. Despite the three treatments each plot received, mistletoe was not eradicated from any stand. Post-thinning tree mortality, suppression of growth response, and the frequency and intensity of mistletoe increased with age of the treated stand.
