Needle pathogens of Rhytismataceae: Current knowledge and research opportunities for conifer foliar diseases

Forest Pathology, Volume 54, Issue 1, February 2024.
Abstract Needle diseases caused by pathogens within Rhytismataceae are increasing in frequency globally where pines are either a predominate species or are grown commercially, and yet remain poorly understood. Here, we provide background information on the current knowledge and management strategies of needle pathogens in the Rhytismataceae and discuss
