| Abstract/Contents: | Field tests were conducted from 1974 to 1981 to evaluate cacodylic acid, glyphosate and paraquat for their effectiveness in vegetation eradication prior to turfgrass renovation. The influence of these herbicides in killing broadleaf weeds and cool season turfgrasses was investigated. The effect of herbicide use on subsequent seedling stand was measured. Variability occurred within and between several of the tests. Chemicals varied in their effectiveness although vegetative kill usually exceeded 90%. Glyphosate was slightly more effective than cacodylic acid or paraquat in the eradication of unwanted grasses. Glyphosate also provided the best control of weed species. High rates of these compounds provided more consistent eradication than low rates and repeat applications provided better vegetation control than did single applications. Mowing before herbicide application did not reduce the effectiveness of these compounds. Increasing spray volume did not alter results and was ineffective in improving the sometimes inadequate control of clover rendered by paraquat. Seedling stand density was reduced by paraquat application made 2 days before, or one hour after seeding, regardless of the rate of application. Glyphosate and cacodylic acid showed no appreciable reduction in stand density. Cacodylic acid, glyphosate and paraquat were evaluated during 1974-81 for effectiveness of weed control prior to turfgrass renovation. Glyphosate was more effective than cacodylic acid or paraquat in the control of unwanted grasses and other weed spp. Mowing before herbicide application did not reduce the effectiveness of the compounds. Seedling stand density was reduced by paraquat application 2 days before or 1 hour after sowing, while glyphosate and cacodylic acid did not affect stand density. |
