Effects Of Glyphosate Applied At Different Times On Dormant Zoysiagrass Cultivars In The Transition Zone, Dani Mcfadden, Jack D. Fry Jan 2023

Effects Of Glyphosate Applied At Different Times On Dormant Zoysiagrass Cultivars In The Transition Zone, Dani Mcfadden, Jack D. Fry

Kansas Agricultural Experiment Station Research Reports

Winter annual weeds become a major problem during winter dormancy in warm-season turfgrass stands. In the transition zone, a winter glyphosate application is a common practice to reduce winter annual weed competition in zoysiagrass before emerging from dormancy in the spring. Research was conducted on the effects of glyphosate application timings on spring greenup and quality of experimental zoysiagrass genotypes compared to commercially available cultivars. Preliminary data from this study revealed a quicker spring greenup when glyphosate was applied in November compared to March. However, March-applied glyphosate significantly reduced cool-season weeds in experimental plots and enhanced quality compared to the …


Herbicide Effects On Establishment Of Zoysiagrass From Sprigs In Two Consecutive Years, Dani Mcfadden, Jack D. Fry Jan 2023

Herbicide Effects On Establishment Of Zoysiagrass From Sprigs In Two Consecutive Years, Dani Mcfadden, Jack D. Fry

Kansas Agricultural Experiment Station Research Reports

Weed control after planting warm-season grasses in the spring can be critical for acceptable establishment of the stand. However, many herbicide labels can be unclear on sprigging restrictions before or after the application of a product. Research was conducted on the growth effects of pre- and postemergence herbicides applied at or near the day of ‘Innovation’ zoysiagrass sprigging. Preliminary data from this study showed granular (Ronstar G) and liquid (Ronstar Flo) formulations of oxadiazon caused the least amount of injury to zoysiagrass.
