| Abstract/Contents: | "Although Sclerotinia homoeocarpa is the name generally ascribed to the fungus that causes Dollar Spot disease on cool season turfgrasses, recent research has proposed a revised name for the fungus that causes Dollar Spot disease as it occurs on cool season turf in the USA1. From a maintenance point of view, Dollar Spot is regarded as one of the most important turfgrass diseases, especially in the USA, but it is a newly recorded disease on turfgrasses across Scandinavia. Having initially been documented in Norway in 20132 and in Sweden in 20143, it is now known to exist on more than 20 Nordic golf courses and has caused up to 70-80% dead turf on affected greens and fairways. To enable effective management of the potential symptoms, it is important to clearly understand the parameters that enable the fungus to actively cause disease. In the USA, disease development is encouraged by an air temperature of up to 30 °C and high relative humidity4,5 but no information is currently available on the environmental conditions that favour Dollar Spot disease in Scandinavia. The results obtained from previous research in Sweden on the in vitro growth requirements of S. homoeocarpa isolates collected from across Scandinavia were inconclusive6, but they proposed lower cardinal temperatures compared to those documented for S. homoeocarpa isolated from Dollar Spot infected turf elsewhere around the world. As part of the current research programme, this study aims to identify whether there are differences in the temperature growth characteristics of S. homoeocarpa isolates collected from turfgrasses in Scandinavia, the USA and the UK." |
