| Abstract/Contents: | "Amicarbazone will be used for control of annual bluegrass in creeping bentgrass fairways. Following control of annual bluegrass, large bare areas or voids will occur and creeping bentgrass will need to be re-established (seeded) in these amicarbazone-treated fairways. There is little information about the effect of soil pH, clay and organic matter on seed-back intervals for creeping bentgrass following use. A bioassy method was used to determine the effect of amicarbazone on bentgrass for soils from California, Georgia, Kentucky, Illinois, New Jersey and Texas. Soils were amicarbazone treated then maintained at field capacity for 10, 20, 30, or 40 days, with intermittent drying intervals for the 20, 30, and 40 day treatments. Overall data indicated major differences for soil amicarbazone activity and bentgrass sensitivity. High pH, with moderate to high CECs, with higher levels of Na (alkaline) and Ca seemed to have prolonged residual amicarbazone activity; verses lower pH, low CEC soils had less amicarbazone residual activity. For soils with pH greater than 6.5 and above, the potential for injury increased. In soils with high Na content, further research is needed to identify potential use rates and limits." |
