| Abstract/Contents: | "Dead spot of creeping bentgrass (Agrostis stolonifera) is incited by Ophiosphaerella agrostis. The objectives of this three year field study were to: 1) elucidate environmental conditions associated with the expression of dead spot symptoms; 2) develop a model to assist in predicting the appearance of dead spot symptoms and epidemics in creeping bentgrass; and 3) elucidate the association between ascospore release and the appearance of new dead spot symptoms. Dead spot symptoms generally did not occur at temperatures (air or soil) below 15°C. Two descriptive models were developed that predicted the appearance of dead spot symptoms with an accuracy of 74% to 80%. Between 2000 and 2002, the appearance of new dead spot infection centers was most accurately predicted (80%) by mean soil temperatures ≥20°C. In years with severe levels of dead spot, the occurrence of major infection events was predicted on 37 of 40 days (93%). A combination of elevated air and soil temperatures, low relative humidity, shortened periods of leaf wetness, and high levels of solar radiation were associated with the development of major dead spot epidemics. Ascospore discharge and the appearance of new infection centers occurred in a cyclic pattern that peaked about every 12 days. New infection centers appeared 3 to 10 days after a large release of ascospores." |
