11057. Cook, R.J.. 1980. Fusarium foot rot of wheat and its control in the Pacific Northwest.. Plant Disease 64:1061-1066.
Fusarium foot rot occurs mainly in low to intermediate rainfall areas of the PNW (20-40 cm) where wheat is grown after fallow. The disease appears related to water stress. Sometimes nitrogen use can induce water stress and was blamed for the disease. Wheat varieties vary in their susceptibility to the disease. The disease can be controlled by minimizing pathogen population increases and by reducing or delaying water stress. Oats should be avoided since they are an excellent host for the disease. Actions to improve water infiltration and storage reduce the chance of water stress. By maintaining residue on the surface, airborne saprophytic fungi will colonize it and prevent Fusarium from doing so. N applications should be based on realistic yields so water stress will not be induced. September seeding, rather than August, avoids excessive foliar growth which can induce water stress.
