Abstract/Contents:"Goosegrass, a weedy C4 grass species occurring throughout the warmer regions of the world, is a major pest in turfgrass systems. Limited research has been conducted on its specific life cycle. The objective of this study was to determine if goosegrass germinating on August 15 will complete a life cycle before the first killing frost, typically November 15 in Clemson, SC. A biotype from Clemson, SC was collected and a growth chamber experiment was conducted to simulate fall maximum and minimum temperatures. Culm, leaf, root and raceme biomass were measured on a weekly basis and growth curves were modeled. The inflection point (i.e. point of maximum growth) occurred for the following growth parameters: culm dry weight 26.5 days after emergence (DAE), leaf dry weight 26.6 DAE, number of raceme per plant 50.7 DAE, raceme dry weight (including germinable seed) 56.0 DAE and root dry weight 42.1 DAE. The completion of the life cycle occurred on October 22 (68 DAE), approximately 3 week before the typical first killing frost in Clemson, SC. In summary, turf managers need to address goosegrass that germinates through approximately the first week of September at this location to avoid production of viable seed."
