Abstract/Contents:Cacodylic acid, glyphosate and paraquat were evaluated for killing vegetation before turfgrass renovation. Cacodylic acid at 11.2 to 22.4 kg/ha was usually less effective in killing grass, especially Kentucky bluegrass [Poa pratensis], than glyphosate at 2.2-4.5 kg/ha or paraquat at 1.1-2.8 kg/ha. Glyphosate provided the most consistent and best grass kill. Trifolium repens was difficult to control, paraquat usually being the least effective. The most consistent control of Taraxacum officinale was obtained with glyphosate. Applying paraquat at 2.2 kg/ha withing 1 week of sowing renovation grasses resulted in a 13-24% stand reduction. Cacodylic acid at up to 22.4 kg/ha and glyphosate at 4.5 kg had little effect on grass stands.
