| Abstract/Contents: | "Annual bluegrass (Poa annua) is a problem weed in winter overseeded and non-overseeded turfgrasses in the southwest desert region of the U.S. Generally, it begins to appear in October and through the winter months when cooler temperatures are favorable for its emergence and establishment. There are few postemergence herbicides that effectively and safely control the weed in overseeded perennial ryegrass in summer bermudagrass. Amicarbazone applications are being refined as new suspension concentrate (SC) formulations are developed and being marketed. Since 2015, the spring timing of application during February to early March appeared to be more efficacious and consistent than earlier winter applications. Sequential applications at 2 weeks apart provided acceptable P. annua control. Rates of 0.125 to 0.140 lb a.i./A and higher performed comparably and consistently to control P. annua at 89% or better while lower rates were not adequate and only marginally controlled P. annua. Higher rates of amicarbazone 2SC caused slight chlorosis of the treated perennial ryegrass. Most treatments caused severe injury and thinning of the ryegrass where overlapping sprays were started and ended at the front and back of treated experimental plots." |
