| Abstract/Contents: | "Maintaining high populations of epiphytic yeasts on plant surfaces is one prerequisite to using yeasts as biocontrol agents in the field; however, the effects of host maintenance practices like irrigation on phylloplane yeasts is unknown. The effect of overhead irrigation (0, 5, and 15 minutes) on the yeast populations on creeping bentgrass and tall fescue were determined by leaf washing and dilution plating. Total yeast populations on bentgrass and tall fescue ranged from 19,232 to 50,733 colony forming units per centimeter squared (cfu/cm2) and 1,023 to 7,467 cfu/cm2, respectively. Five minutes of irrigation on field plots significantly reduced the yeast populations on bentgrass by 31% and on tall fescue by 26%. Total yeast populations on irrigated bentgrass (15 minutes) were reduced by 45% compared to non-irrigated bentgrass, however, no differences in yeast populations sizes were observed between the treatments two hours after the irrigation event. Yeast populations on turfgrass were observed to follow a cyclic pattern; on successive days the yeast populations on bentgrass were higher in the morning compared to eight hours later in the afternoons. Population decreases during the day were observed to be similar to the reductions observed with irrigation." |
