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.

俄勒冈州抗喹诺酮冬小麦中的野黑麦（Secale cereale L.）控制措施

在西北太平洋（PNW）的旱地软白冬小麦产区，管理冬季一年生禾本科杂草一直是一项挑战。最近开发出的抗喹唑啉草酮（CoAXium）小麦品种使种植者可以使用乙酰-CoA羧化酶（ACCase）抑制性除草剂喹唑啉草酮（QP）进行苗后除草。2021-2022 年和 2022-2023 年的两个冬小麦生长季节，在俄勒冈州亚当斯附近进行了田间试验，以评估 QP 对野生黑麦的药效和作物安全性。分别在 2021-2022 年和 2022-2023 年评估了使用 QP 控制唐氏锦鸡儿和节节山羊草的效果。无论测试的比率、佐剂和喷洒量如何，Quizalofop 处理都能有效控制野黑麦（≥ 95%）、羽状黑麦草（≥ 87%）和节节山羊草（99%）。春季施用的 QP 不会对冬小麦造成伤害。结果表明，抗喹禾灵小麦技术可以帮助西北太平洋地区的小麦种植者有选择性地控制冬季一年生禾本科植物。

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
