Abstract
Managing winter annual grass weeds has long been a challenge in the dryland soft white winter wheat-producing regions of the Pacific Northwest (PNW). The recent development of quizalofop-resistant (CoAXium) wheat varieties allows growers to use the acetyl-CoA carboxylase (ACCase)-inhibiting herbicide quizalofop (QP) for postemergence grass control. Field experiments were conducted over two winter wheat growing seasons in 2021-2022 and 2022-2023 near Adams, OR, to evaluate QP efficacy on feral rye and for crop safety. Downy brome and jointed goatgrass control with QP were assessed in 2021-2022 and 2022-2023, respectively. Quizalofop treatments provided effective feral rye (≥ 95%), downy brome (≥ 87%), and jointed goatgrass (99%) control regardless of rates, adjuvants, and spray volumes tested. Spring-applied QP caused no winter wheat injury. Results indicate that the quizalofop-resistant wheat technology can help PNW wheat growers selectively control winter annual grasses.
期刊介绍：
Weed Technology publishes original research and scholarship in the form of peer-reviewed articles focused on understanding how weeds are managed.
The journal focuses on:
- Applied aspects concerning the management of weeds in agricultural systems
- Herbicides used to manage undesired vegetation, weed biology and control
- Weed/crop management systems
- Reports of new weed problems
-New technologies for weed management and special articles emphasizing technology transfer to improve weed control
-Articles dealing with plant growth regulators and management of undesired plant growth may also be accepted, provided there is clear relevance to weed science technology, e.g., turfgrass or woody plant management along rights-of-way, vegetation management in forest, aquatic, or other non-crop situations.
-Surveys, education, and extension topics related to weeds will also be considered
