Abstract/Contents: | "Stink grass (SG) (Eragrostis cilianensis), love grass (LG) (E. pectinacea) and witch grass (WG) (Panicum capillare) are three anual[annual] grasses frequently infected with Sclerophtora macrospora in undisturbed bare ground sites over which water flows and stands after rains. The source of primary inoculum can be oospores within the site, and/or zoospores brought in by flowing water from oospores or asexual sporangia in adjacent areas. In greenhouse tests, SG and LG oospore inocula infected seedlings of all three grasses, and also seedlings of wheat and barley. WG oospore inoculum infected WG but not SG or LG seedlings. Asexual zoospores from bromegrass and SG infected SG and LG seedlings, but not WG seedlings. With SG seedlings, the pathogen was detected in soil from two of six field sites that that supported crazy-top corn or diseased plants of the three annual grasses. In a controlled test, corn oospore inoculum infected SG and LG seedlings." |
