Abstract/Contents: | "Several southeastern Virginia golf courses had reported difficulty in controlling annual bluegrass (Poa annua L.) in their bermudagrass fairways. The standard control program for annual bluegrass at these courses had been a fall application of simazine. Plants were collected from a total of six fairways at three golf courses and maintained in a greenhouse. Seed was also collected at the research station in Virginia Beach from annual bluegrass plants growing in areas that had not been treated with simazine. Seed from these plants were used in trials to determine if resistance to simazine had occurred. Simazine applied preemergence at 1.12 and 2.24 kg ai/ha did not control annual bluegrass from two of the three golf courses. In a second trial to verify the level of resistance, these biotypes were not controlled by simazine applied at rates up to 9 kg ai/ha. Prodiamine at 0.84 kg ai/ha and ethofumesate at 1.1 kg ai/ha applied preemergence controlled annual bluegrass from all three golf courses. Triazine-resistant annual bluegrass had developed at two golf courses in southeastern Virginia, but these biotypes can be controlled using alternative preemergence herbicides." |
