Abstract

Abstract

There is a void in registered growth regulators for use on turfs in Germany. This investigation was initiated to study the effects of a new growth regulator, N-[2, 4dimethyl- 5-[[(trifluormethyl) sulfonyl]amino]phenyl]acetamide (mefluidide), on turfgrasses grown under conditions in Germany. Initial investigations indicate that turfgrass growth can be retarded in both length and in terms of the number of seedheads formed. A growth depression of approximately 40 % can be sustained at 4 weeks after application. The normal mowing interval of about 8 days in Germany could thus be extended up to several weeks. The best results from mefluidide were obtained when the grass was treated about 3 to 4 days after mowing, while the optimum application rate was 240 g/ha.
