| Abstract/Contents: | "Anthracnose which is caused by the fungal pathogen Colletotrichum cereale is a serious disease in many cool-season turfgrasses but the fungus has not been reported as an aggressive pathogen on fine fescues (Festuca spp.). Symptoms commonly associated with anthracnose disease were observed in fine fescues on the Rutgers turfgrass research farm in Adelphia, NJ. The objective of this study was to determine if an isolate of C. cereale obtained from symptomatic fine fescues was pathogenic to fine fescue turf and if fine fescue cultivars and accessions collected from Europe varied in susceptibility. Pathogenicity of C. cereale isolate (FF1A) obtained from symptomatic fine fescues in Adelphia, NJ was evaluated on four hard fescue (F. brevipila) and four Chewings fescue (F. rubra ssp. commutata.) cultivars and accessions using a 5 x 10-4 conidial suspension in a growth chamber. Additionally, an isolate of C. cereale (HF217C) from annual bluegrass was included for comparison. Disease symptoms were observed at five to 11 days post-inoculation with both isolates on all cultivars and accessions. Infection was confirmed by morphological evaluations, re-isolation from symtomatic [symptomatic] tissue, and real-time PCR. Overall, the C. cereale isolate obtained from fine fescue was more pathogenic than the annual bluegrass isolate. Hard fescue cultivars 'Sword' and 'Beacon' exhibited low susceptibility, and three non-commercial accessions (two Chewings fescues and one hard fescue) were very susceptible to the fine fescue isolate. This study confirmed that C. cereale can be a major pathogen of the fine fescues and breeding for resistance should be a goal when developing new cultivars." |
