| Abstract/Contents: | "Poa annua (annual bluegrass) is the most pervasive weed in turfgrass worldwide. Poa annua has developed resistance to acetolactate synthase inhibitors, glyphosate, mitotic inhibiting herbicides, triazine PSII inhibitors, and likely indaziflam. The number of herbicide options has diminished considerably. Glufosinate is a contact non-selective postemergence herbicide in the glycine family known to act quickly and show symptoms in less than 3 hours. Glufosinate has been reported to control Poa annua; however, due to its contact nature, it is generally seen as less effective than glyphosate and sulfonylurea herbicides. Combinations of glufosinate with other herbicides could be more effective than glufosinate alone and could aid in preventing resistance development. Field studies were initiated from January to March 2023 to investigate herbicide combinations with glufosinate to control Poa annua in bermudagrass (Cynodon dactylon) turf. Treatments included glufosinate at 0.85 kg ai/ha, glyphosate at 0.28 kg ai/ha, oxadiazon at 2.27 kg ai/ha, indaziflam at 0.033 kg ai/ha, and flumioxazin at 0.28 kg ai/ha. Each herbicide was applied alone and in a tank mixture with glufosinate. Application was made in January 2023 with a CO2-pressurized backpack sprayer calibrated at 280 L ha-1. Results showed the herbicides applied independently effectively controlled Poa annua, but in a mixture with glufosinate, increased control to above 90% at 25 days after application (DAA). Oxadiazon and indaziflam alone displayed <10% of Poa annua control at any rating date.In conclusion, adding glufosinate into herbicide tank mixtures successfully controls Poa annua in bermudagrass turfgrass." |
