Abstract/Contents:"The epidemiology of A. agrostis was investigated in a bentgrass field near Corvallis, Oregon. Each October from 1990-1992, nylon mesh pouches, each containing 10 galls, were buried in the field or placed in microplots containing bentgrass cv. Highland. Pouches were collected monthly or bimonthly between December and June and nematodes per gall determined. Nematode egression from galls began in late March and was completed by mid-May, corresponding to the period of flora initiation in bentgrass. In 1991 and 1992, 0.9 m2 plots were inoculated with 0, 1, 5, 15, 50, 120, or 200 galls/plot. The disease severity (number of galls) and disease incidence (percentage seed heads with galls) increased linearly at inoculum densities below 50 galls/plot. At higher inoculum densities, disease increase approached an asymptote. In 1991, plots were established to determine the characteristics of disease spread. Foci were established by placing 0, 5, 50, or 500 galls along a 30-cm section of row in the fall. In July 1992, seed heads were harvested at 30 and 60 cm from each focus within and across plant rows. Nearly all subsequent infestations were found within 30 cm of foci at all inoculum levels. These disease spread and incidence data explain stable distributions of A. agrostis observed in Oregon bentgrass fields."
