Abstract/Contents:"Establishment of Meyer zoysiagrass (Zoysia japonica Steud.) from vegetative plugs generally requires a minimum of three growing seasons; whereas, establishment from sprigs requires about two growing seasons. The objective of this study was to determine if establishment from regrowth of harvested sod could be hastened by herbicides that reduce weed competition. Meyer zoysiagrass was established from plugs at Silver Spring, MD in 1983, and the mature stand was harvested in Aug 1988. On 10 Apr 1989, the area was lightly rototilled and the site was separated into two areas. Area I was hand raked to remove all loosened plant debris; whereas, Area II was not raked and sod ribbons and debris were allowed to remain in place. Both areas were rolled, and herbicides were applied over primarily bareground in Area I and bareground plus plant debris in Area II. Plots were 5 by 10 ft and arranged in a randomized complete block with either four (Area II) or five (Area I) replications per treatment. The herbicides (dithiopyr at 0.5 lb/A; pendimethalin at 3.0 lb/A; prodiamine at 0.65 lb/A; DCPA at 10.5 lb/A; oxadiazon at 3.0 lb/A; fenoxaprop at 0.35lb/A and quinclorac at 1.5 lb/A) were applied at recommended times in 50 gpa at 36 psi. Quinclorac was tank-mixed with 2 pts/A of BAS 090 surfactant. Nitrogen from urea was applied at 1.0 lb N/1000 ft2 on July 1989, and 15 May, 13 June, and 10 July 1990. Plot area covered by weeds or zoysiagrass was determined visually on a 0 to 100% scale. All data were subjected to analysis of variance and significantly different means were separated at P=0.05 by Duncan's multiple range test." 1989 and 1990 results are also discussed.
