| Abstract/Contents: | "Methiozolin controls annual bluegrass (Poa annua) in golf course putting greens. Previous research indicates root-exposure is necessary for maximum herbicide efficacy. Therefore, methiozolin must be available for root uptake in the soil for successful field application; methiozolin must not be excessively sorbed to soil and not readily leached from the root-zone. Research was conducted to evaluate methiozolin sorption to various sand-based soil media, typical of many golf course putting greens. Soil solution batchequilibrium methods were used with 14C-methiozolin at 1 mg L-1 to determine sorption (Kd) values for United States Golf Association (USGA) grade sand with 0 to 20% (w/w) peat, USGA grade sand-based root-zones that were established as putting greens for 0, 10, and >15 years, and a Wickham sandy loam (locally collected field soil). Results indicate that organic matter content greatly influenced soil sorption, while soil pH did not influence soil sorption. Clay content was not included in the analysis due to its narrow range (1.3 to 7.5%) in the soil media evaluated. Kd values ranged from 0.4 mg L-1 for pure sand to 29.4 mg L-1 for sand with 20% peat. Native field soil had a Kd value of 6.4 mg L-1. Kd values observed are consistent with other soil-active herbicides. Soil media with 0.3 to 6.1% organic matter resulted 9.5 to 32.1% of applied methiozolin in solution after equilibrium. Averaged across soil media, 24% of applied methiozolin is available for root uptake. This level of sorption suggests resistance to loss through leaching displacement." |
