| Abstract/Contents: | "Gray snow mold caused by Typhula spp. is a major problem on golf courses where snow cover persists for periods exceeding 60 days. Even though the disease is primarily managed by preventive fungicide applications in the fall prior to permanent snow cover, the pathogen still produces varying degrees of damage to the golf course. Gas chromatography/mass spectrometry analysis indicated that residues of chlorothalonil (10-100 ug/g) and fludioxonil (1-5 ug/g) did not diminish in the verdure through the winter, yet many plots treated with these fungicides, either alone or in combination, often had more than 50% turf damage. In-vitro studies were undertaken to determine sensitivity of T. incarnata and T. ishikariensis to fludioxonil, propiconazole and chlorothalonil. Typhula isolates collected from fungicide treated plots were grown on half-strength potato dextrose agar amended with varying fungicide concentrations. Growth of the most T. ishikariensis isolates were suppressed by more than 50% on agar amended with 10 μg/ml chlorothalonil, propiconazole and fludioxonil whereas growth of some T. incarnata isolates were not suppressed by more than 50% on agar amended with 10 ug/ml chlorothalonil (compared to a non-amended control). This suggests that variability in fungal sensitivity to these fungicides may be as important as fungicide persistence in influencing snow mold development." |
