Abstract
Relatively few spores of Helminthosporium sativum P.K. and B. were found on the crowns and roots and in the soil surrounding the crowns and roots of established stands of bromegrass, Bromus inermis Leyss., and crested wheatgrass, Agropyron cristatum (L.) Gaertn. Isolations from crown and root tissue yielded few cultures of H. sativum. Wheat and barley grown in comparable locations had high rates of infection, and spores were produced in abundance. These grasses apparently do not serve as an important infection reservoir for H. sativum in crop rotation and they should be useful in eradicating the pathogen from the soil. Fusarium culmorum was rarely isolated from grasses, although other Fusarium spp. were common.
