Abstract: The effect of Cephalosporium qramineum infection in winter wheat was studied relative to the environmental conditions which affect growth of the wheat and the-incidence-of disease.Studies in the fieid and with controlled environment chambers showed that warm soil temperatures and ample moisture availability contribute to growth of the wheat roots and an increase in-disease incidence.Fertilizer at the time of planting increased-Cephalosporium stripe disease as it simultaneously enhanced fall root growth.Wheat--with a greater autumn root mass was more subject to root damage in the spring thaws.Numerous breaks in the roots allowed multiple entrance points for the pathogen and a greater possibility for infection of any one plant.Although no immune wheat varieties were discovered, a number of selections were found to have varying degrees of resistance.A large molecular weight, viscous, extracellular fungal polysaccharide was shown to be present in the infected wheat and to be a contributing factor in restricting fluid movement in wheat leaves.
