Diplodia tip blight is the most ubiquitous and abundant disease in Spanish Pinus radiata plantations. The economic losses in forest stands can be very severe because of its abundance in cones and seeds together with the low genetic diversity of the host. Pinus resinosa is not genetically diverse in North America either, and Diplodia shoot blight is...
Article
Increasing prevalence of conifer needle pathogens globally have prompted further studies on pathogen identification and a better understanding of phylogenetic relationships among needle pathogens. Several Lophodermella species can be aggressive pathogens causing needle cast in natural pine forests in the USA and Europe. However, their relationships...

Key message Pathogen-induced defoliation resulted in a reduction in transpiration, an upregulation of photosynthesis in the early growing season, and no change in NSC reserves across stem, root, and foliar tissues. Abstract The defoliation of eastern white pine (Pinus strobus L.) by native fungi associated with white pine needle damage (WPND) can...
Article
Oak wilt is slowly expanding in the northeastern United States. Several nitidulid beetle species are known vectors of the fungus [Bretziella fagacearum (Bretz) Z. W. De Beer, Marinc., T. A. Duong, and M. J. Wingf (Microascales: Ceratocystidaceae)] that causes this disease, acquiring spores from fungal mats on infected trees and transmitting them to...

Presently, there are no specific management recommendations for addressing declining stand health relating to WPND induced...
Article
Climate model predictions for the northeastern U.S. forecast a warmer and wetter climate, which favors the survival, reproduction and dispersal of foliar diseases of eastern white pine, collectively called White Pine Needle Damage (WPND). Foliar diseases cause defoliation of white pine, leading to growth reductions, canopy dieback and predisposing...
Article
White Pine Needle Damage (WPND) is a complex of foliar fungal pathogens that have established as a chronic disease impacting eastern white pine (Pinus strobus L.) stands in the northeastern United States. With long-term ecological and economic impacts in mind, it is critical to quantify the negative effects of this disease on tree and forest health...
Article
Current plant regulatory protocols rely on lists of known pathogens, but many forest pathogens are unknown. Live plants are inspected at ports of entry for disease symptoms, but many plant pathogens can persist asymptomatically. Current efforts should be expanded by including random sampling of both symptomatic and asymptomatic plant tissues. Molec...
