Abstract/Contents:"The warm autumn temperatures in the low elevation desert areas of southern California (Palm Springs) U.S.A. allow renovated common Cynodon dactylon (L.) Pers. to re-grow quickly and compete with seedling ryegrass (Lolium perenne L.) overseed species. This study evaluated common overseeding pre-treatments being used by turfgrass managers to imporove the speed, density and uniformity of ryegrasses seed establishment overseeded into Cynodon dactylon lawns, fairways and roughs. The uses of contact herbicides and plant growth regulators were evaluated to determine if they offered any advantage or disadvantage in obtaining a high quality stand of overseeded perennial ryegrass in the short time-frame (four weeks) before the turf areas opened for play. Treatments included, Scythe¬ģ (Pelargonic Acid), Primo¬ģ (Trinexapac-ethyl) at one and two applications compared with the standard or "check" treatment, slowly drying the Cynodon dactylon prior to renovation and planting of the overseed species. There did not appear to be any difference in the initial establishment of the check plots and those treated with any of the pre-overseeding chemicals. The results of this study indicate that there is no advantage to applying these preoverseed chemicals to retard the regrowth of common Cynodon dactylon during the germination and early establishment of perennial ryegrass in the overseeding process. The Primo pre-treatment coupled with a second application four weeks after overseeding did significantly reduce clipping yields during the subsequent five-week period."
