Abstract/Contents:"The identification of allelopathic turfgrass varieties would be a valuable tool for enhancing integrated pest management strategies and reducing herbicide applications. Ecological competition can be separated from allelopathy only with stringent experimental guidelines, but separation of these interactions is critical. The objective of this study was to reevaluate tall fescue (Festuca arundinacea Shreb.) and to evaluate several other cool season turfgrass species for allelopathic activity in competitive and noncompetitive environments. Leaf extracts of tall fescue, Kentucky bluegrass (Poa pratensis L.), annual bluegrass (Poa annua L.), perennial ryegrass (Lolium perenne L.) and hard fescue (Festuca longifolia Thuill.) were applied to seed in germination studies of five recipient species. A leachate recycling apparatus was used to evaluate leachate from all five of the turfgrass species for inhibition of radish (Raphanus sativus) germination and seedling growth. A density-dependent competition study was conducted with soil from underneath tall fescue and soil treated with lactic and succinc acids to demonstrate competitive and allelopathic effects on large crabgrass (Digitaria sanguinalis L.). In petri dish bioassays all turfgrass species inhibited seed germination and root growth regardless of which species was considered. Conversely, the leachate recycling apparatus did not demonstrate inhibition by any of the turfgrass species. The production of significant amounts of allelochemicals in an agronomic environment by any of the five cool-season turfgrass species evaluated seems doubtful. Weed infestation differences between stands of different turfgrasses is probably due to other ecological mechanisms such as competition for light, water, and nutrients."
