| Abstract/Contents: | "An unknown patch disease was observed on creeping bentgrass putting greens at Landfall Country Club in Wilmington, NC in summer 2002 and 2003. Affected greens were established in 2001 with a blend of cultivars 'A-1' and 'A-4'. Soil pH ranges from 7 to 8 at this location due to poor quality irrigation water. Circular patches of turf initially exhibited signs of wilt, followed by chlorosis and orange necrosis. Roots and crowns were necrotic and colonized with dark, ectotrophic hyphae. A fungus resembling Magnaporthe was consistently isolated from necrotic roots and crowns. Unknown isolates mated in vitro with M. poae 73-15 and are therefore M. poae mating type a. Pots of A-4 creeping bentgrass were inoculated with M. poae and placed in growth chambers with 12 hr day/night cycles at 30/25°C, 35/25°C, or 40/25°C. Foliar chlorosis and necrosis was observed 28 days after inoculation at 30°C and 35°C, but not at 40°C. Roots and crowns of inoculated plants were necrotic and colonized with ectotrophic hyphae, and M. poae was readily isolated from necrotic tissue. This is the first report of summer patch of creeping bentgrass within the zone of adaptation for this turfgrass species." |
