First report of a Labyrinthula spp. causing rapid blight of Agrostis capillaris and Poa annua on amenity turfgrass in the UK
Plant Pathology 55 (2), 306-306
Abstract: In 2004 turf samples of Agrostis capillaris and Poa annua showing watersoaking and discoloration were obtained from a golf course in Scotland. The watersoaked patches increased in size and number during periods of warm dry weather to around 25 cm diameter, and the affected sward continued to discolour to red-brown over several weeks. All samples contained fusiform cells which are typical of those described for the genus Labyrinthula. Labyrinthula species are single-celled organisms that occur in aggregations in culture and which exhibit a distinctive gliding motion within a colonial network of slime filaments. The taxonomy of Labyrinthula is uncertain; although presently classified in the kingdom Chromista, they are not closely related to other included members. Three-week-old A. capillaris seedlings and P. annua plants were inoculated with the Labyrinthula spp. isolated from affected turf which showed symptoms within 7 days.
