Abstract/Contents: | "Take-all of bentgrass (causal agent is Gaeumannomyces graminis var. avenae; Gga) can be a serious disease on new golf course putting greens and fairways. Gga is believed to be the most active during cool, moist conditions of spring and fall while symptoms appear during periods of heat and water stress. Our objective was to develop a growth chamber assay to assess the effects of microbial inoculants, organic amendments, and chemical controls on take-all incidence and severity. Conetainers [containers] were set up using a sand rootzone mix amended with various amounts of millet seed colonized by Gga as inoculum. The cones were seeded with creeping bentgrass (Agrostris palustris, cv. Penneagle) and placed in a growth chamber on a 12 hr day with 18°C day and 12°C night. Symptoms (chlorotic leaf blades and tip dieback) were observed at 16-20 days after set-up. The mean percent infected roots were positively correlated to the percent symptomatic turf observed. The effect of microbial inoculants on disease incidence and severity will be assessed." |
