Abstract
After 2 seasons, microsclerotial populations of Cylindrocladium sp. were higher in soils planted with alfalfa Medicago sativa, and Sudan grass Sorghum bicolor and not different in soils with spring wheat Triticum aestivum than populations in noncropped, fallow plots. Lower populations of the fungus were detected in soils planted with flax Linum usitatissimum than in the fallow ones. Highest disease incidence in black spruce Picea mariana transplants occurred when grown in plots treated with alfalfa, Sudan grass, and wheat. Disease incidence was lower in transplants grown in the flax plots than in those grown in the other plots. Spruce mortality was also less in the flax plots compared with all other treatment plots. -from Authors
