Abstract/Contents: | "Airborne Drechslera poae conidia were collected over Kentucky bluegrass with a Kramer-Collins intermittant spore trap and a Burkard 7 day continuous spore trap in 1979 and 1980. Relative humidity, rainfall, and leaf wetness were recorded from April to November. Peak concentrations of airborne D. poae were observed in late May and June. Infrequently, moderate releases of conidia were observed in April or early May. Very few conidia were trapped from July to November. The diurnal discharge of D. poae conidia which peaked between 1200 to 1400 hours coincided with abrupt decreases in the moisture levels in the turf microclimate. Few conidia were collected in the late evening or early morning. Negligible releases of conidia were noted during periods of prolonged leaf wetness or high relative humidity." |
