| Abstract/Contents: | "Annual bluegrass is a major weed in turf. In Arizona, prodiamine or dithiopyr are applied in late August to provide pre-emergent control of annual bluegrass and to allow the herbicides to dissipate enough to allow overseeding with perennial ryegrass in October. This study was done to compare the rates of dissipation of prodiamine and dithiopyr in bermudagrass turf from the time of application until overseeding at two different sites in Arizona. Over 98% of the residue from both herbicides remained in the turf/thatch layer throughout the course of the experiment. Dithiopyr dissipated approximately twice as rapidly as prodiamine at both sites. At the time of overseeding, 30 to 40% of the prodiamine remained in the turf whereas only 12 to 16% of the dithiopyr remained. These results suggest that prodiamine could be applied earlier in the year to allow time for the herbicide to dissipate before overseeding while dithiopyr-treated areas could be overseeded earlier to allow the perennial ryegrass to outcompete annual bluegrass seedlings." |
