Core Ideas Bicyclopyrone + bromoxynil might be an alternative chemical control tool in wheat in the Pacific Northwest. Bicyclopyrone + bromoxynil provided a very good control of mayweed chamomile. High application rates of bicyclopyrone + bromoxynil provided a good control of prickly lettuce.Chemical weed control options in wheat ( Triticum aestivum L.) cropping systems of the Pacific Northwest (PNW) are currently limited due to the presence of resistant weed biotypes. The efficacy of a new post‐emergence herbicide in wheat, bicyclopyrone + bromoxynil (Talinor), was evaluated for mayweed chamomile ( Anthemis cotula L.) and prickly lettuce ( Lactuca serriola L.) control in eastern Washington and Oregon in 2016 and 2017. Bicyclopyrone + bromoxynil provided superior control of mayweed chamomile in winter wheat compared with pyrasulfotole + bromoxynil (Huskie). Mayweed chamomile control was similar across all three rates of bicyclopyrone + bromoxynil used in the study. Pyrasulfotole + bromoxynil provided greater control of prickly lettuce in spring wheat than bicyclopyrone + bromoxynil except when bicyclopyrone + bromoxynil was applied at the highest rate. Bicyclopyrone + bromoxynil will provide winter wheat growers with an effective option for controlling mayweed chamomile, and at higher use rates, with an alternative option for prickly lettuce control in spring wheat.
