a disease called white pine blister rust. Restor-ing white pine is an important goal on many forests, and pruning is one tool that can help. This publication is intended to help forest owners and managers make decisions about pruning to reduce blister rust mortality in young, to year-old white pine. 1 Figure n white pine (Pinus. Pruning when planting involves thinning out For coniferous species such as Grand fir, Western white pine, and the spruces, late winter to early spring is the preferred time to prune. Do not prune live branches Prune one of the branches to a length of 6 to 10 Size: KB. Survey lines were located in areas that had been pruned to control blister rust (Cronartium ribicola) 10 years previously and adjacent control (unpruned) areas in 10 stands of western white pine (Pinus monticola) in coastal and interior British Columbia. Stands were classified as densely stocked, moderately stocked, or open. Cankers were tallied and their position by: Thinning and pruning western white pine: a potential for reducing mortality due to blister rust. Res.

Get pruning tools. When trimming a white pine tree, gather a few tools to make your cuts. Hand pruners can be used for cutting small branches that are around a 1 ⁄ 2 inch ( cm) wide. Lopping shears are pruners with long handles that gives them more leverage to cut larger : 21K. Pine Tree Pruning How To. When you remove a branch, cut all the way back to the collar, or thickened area near the trunk. If you are cutting a branch that is more than an inch (3 cm.) in diameter, don’t make one cut from top to bottom, as this may strip the bark down the trunk when the branch breaks free. Pine straw revenues may not make thinning a pine stand financially attractive. Typically, once a stand is thinned in Georgia it is no longer raked for straw. Conversely, loblolly pine can be thinned at a later time to promote stand pruning and assist with making more attractive “final crop” trees for sawtimber. Trimming White Pine. Asked Febru , PM EST. If it's just the upper branches blocking sunlight to the lower branches, pruning the trees to thin bushy parts helps ensure lower branches remain green and healthy. Water stress can cause foliage to die, especially along the oldest branches of trees such as pines.
White pine blister rust was introduced to the United States from Europe in the early ’s. The disease had a devastating effect on western white pine trees, since they had not evolved together with the disease. Blister rust also attacks other five needle pines such as whitebark pine, eastern white pine and sugar pine. In western white pine and sugar pine, preventive pruning prevented mortality from WPBR (Martin et al. , Hunt , O'Hara et al. ), and 80% of infections were found in the lower crown of eastern white pine (Lehrer ). Thinning and Pruning Grass and woody plants compete with white pine and must be controlled if white pine growth is reduced. If you have a backpack sprayer, the necessary chemicals, and protective gear, count on spending 5 to 10 hours per acre for this task. Herbicide and labor for a pine release treatment is approximately $70 per acre. The fungus Elytroderma deformans causes a serious needle disease of pines in western North America and is considered the most important needle disease of ponderosa pine in Montana. While important, there has been limited evaluation of pre-commercial thinning or other treatments on disease incidence. Our study assessed the efficacy of various silvicultural treatments to reduce impacts from.
