| Abstract/Contents: | "Magnaporthiopsis meyeri-festucae has been proven to be a new summer patch casual pathogen on hard fescue and Kentucky bluegrass. Multiple isolates of M. meyeri-festucae were collected during the summer of 2013 and 2016 at Horticultural Farm 2 at Rutgers University. Isolates were tested in an pathogenicity assay for turf symptomolgy by phenotypic response in hard fescue and Kentucky Bluegrasss through growth chamber experiments. For the assay three Magnaporthiopsis poae and seven M. meyeri-festucae isolates were chosen. Overall on two cultivars of hard fescue (Beacon, and Predator), and one kentucky bluegrass cultivar (Baron) results showed the three isolates of M. poae reduced root growth by 65% to 80% with isolate C11 showing 80% reduction, whereas the seven M. meyeri-festucae isolates showed a root weight reduction of 0% to 63% with isolate SCR9 showing 63% reduction. The goal of this research was to determine an isolate that exhibits higher levels of pathogenicity and compare to the traditional casual pathogen M. poae. The results of this study indicate there are varying levels of pathogenicity within M. meyeri-festucae and these more severe isolates can be used in breeding and management research to reduce impact of this pathogen." |
