	abstract = "Black-stain root disease, caused by Verticicladiella wageneri, was found in 18 of 23 plots of Douglas-fir 12 years after a precommercial thinning. No disease was found in six unthinned control plots. Of the Douglas-fir trees left after thinning, 35, 28, 21, and 19 percent were infected in the plots thinned to an average of 1175, 832, 610, and 355 stems per ha, respectively. Thinning of Douglas-fir stands may create disturbances attractive to vectors of V. wageneri Forest Sci. 29:12-14",
