| Abstract/Contents: | "Anthracnose disease of turfgrass, caused by the filamentous ascomycete Collectotrichum graminicola, has been difficult to manage in part because of variability in the effectiveness of control measures in different regions. We have initiated a study to examine the role in disease control played by variability of the fungus. Phylogenetic relationships among fungal isolates from different regions of the U.S. and Canada were estimated by sequencing the ribosomal DNA internal transcribed spacer (ITS) region. Resistance to azoxystrobin and thiophanate-methyl, two widely used fungicides, was also examined using plate assays. The phylogenetic analyses revealed that C. graminicola isolates infecting turfgrass species could be divided into two major clades. While all methods of analysis showed the turfgrass-infecting isolates to be distinct from cereal-infecting isolates of C. graminicola, ITS analysis alone did not resolve the relationships of the two major turfgrass clades to the cereal-infecting isolates. Examination of 25 turfgrass-infecting isolates for sensitivity to the fungicides azoxystrobin or thiophanate-methyl revealed variability in resistance to those chemicals, while also demonstrating that reactions of individual isolates could not be predicted based on phylogeny. Thus, the traits of resistance of C. graminicola to these two fungicides have been selected independently more than once in different fungal lineages." |
