Rhabdocline weirii is a fungal plant pathogen. The pathogen, along with Rhabdocline pseudotsugae , causes Rhabdocline needlecast; R. weirii only affects Douglas-fir trees.^[1]^[2] The disease causes the needles of the tree to discolor and eventually fall from the tree. The pathogen often makes Douglas-fir trees unsalable as Christmas trees and affects the Christmas tree farming industry.^[1]
