| Abstract/Contents: | "Seedlots of 42 bentgrasses are being screened for resistance to two isolates for each of two newly recognized root-infecting fungi; Phialophora graminicola and Leptosphaeria korrae. These fungi cause summer patch and necrotic ring spot diseases, respectively. The resistance studies are conducted for an 8-week period in controlled-environment chambers. Percentages of plants which survive the test will be reported in early winter. Surviving plants from selected seedlots will be returned to the plant breeder from whom the seed was supplied; this may assist in development of selections with higher levels of resistance. Methodology was also developed to conduct similar screening studies on vegetatively propagated bentgrasses. This research revealed the potential for further complexities to exist in the etiology of take-all patch of bentgrasses, which have been thought to be caused only by Gaeumannomyces graminis var. avenae. In New York, it is now also known that P. graminicola causes a hot weather form of take-all patch on bentgrasses, and this possibility was confirmed during the development of methods for this project, sponsored by the USGA-Green Section. These new findings have relevance to the likelihood that certain disease management strategies will or will not be effective during summer. The project was terminated prematurely because the principal investigator moved to another position." |
