Abstract/Contents: | "The effect of the fungicide azoxystrobin on phyllosphere microbial populations were evaluated in the turfgrasses Agrostis stolonifera L. and Poa pratensis L. leaves from both species were collected 4 months after treatment with azoxystrobin at 6 g/100 m2 and sonicated in saline solution; the extract was serially diluted and plated. Colonies growing on potato dextrose agar (PDA) medium amended with antibiotics showed four general morphotypes for yeast (pink, salmon, orange, and white) and at least 14 morphotypes for filamentous fungi. On PDA medium amended with benomyl, four bacterial morphotypes (Yellow, white, orange, and salmon) were found. The number of colony-forming units was higher in leaf washings from A. stolonifera than from P. pratensis. In both grasses, the predominant yeast morphotypes was white, followed by orange and salmon. In leaves treated with azoxystrobin, counts of most of the different yeast morphotypes were greater than in controls not treated with the fungicide, whereas counts of filamentous-fungi or bacteria morphotypes in azoxystrobin treatments did not differ from those in the untreated controls. Orange bacterial colonies were the most common morphotypes for A. stolonifera, while for P. pratensis, yellow bacteria were most common. Further study is required to differentiate the morphotypes into species and to assess whether there were changes in specific groups of filamentous fungi and bacteria, even though the total counts remained the same between fungicide-treated and untreated leaves." |
