Abstract

Abstract : Research concerning the cultural practice of golf course fairways is important because legislation on pesticide reduction in Europe and North America may potentially cause serious weed problems. Establishing a strong, competitive turfgrass sward may aid in reducing the invasion of broadleaved weeds and Poa annua L. The objective of this research was to determine changes in the grass species composition and weed occurrence of in‐use fairway turfs after repeated overseeding of three grass species separately: Lolium perenne L., Festuca rubra L., and Poa pratensis L., all at rates 300 kg ha −1 . Overseeding was conducted with a disc seeder, alone or in combination with extra fertilizer (50 kg N + 34 kg P ha −1 ) in either May or September on three Danish golf courses from 2011 to 2013. Results showed no increase in the population of F. rubra or P. pratensis after 3 yr of overseeding. Lolium perenne was successfully introduced when seeded in autumn and when extra fertilizer was added immediately after overseeding. None of the overseeding treatments reduced the occurrence of P. annua, Taraxacum officinale F.H. Wigg., Bellis perennis L., or Trifolium repens L. The results are discussed in relation to the fact that the fairways were unirrigated and that they were open to play after overseeding.
