Weeds pose a significant threat to Oregon field crops by reducing yields and compromising the quality of the harvested products. In fall 2024, Oregon stakeholders were surveyed to identify the key challenges and needs related to weed management in field crops. The survey consisted of eight questions, developed based on expert input and review of relevant literature, divided into three sections: respondent demographics, resource and support needs, and current weed management challenges and economic impacts. A total of 184 responses were collected statewide, with growers and crop consultants as the primary participants. Most respondents were from western Oregon, which may introduce a geographic bias to the findings. Respondents expressed particular interest in new herbicide technologies and herbicide resistance. Field days were the most preferred method for receiving weed management information. Annual bluegrass, Italian ryegrass, and roughstalk bluegrass were reported as the most problematic grass weeds, while wild carrot was the most problematic broadleaf weed. Most respondents reported an average weed control cost of US$125 to US$250 per hectare, and the majority indicated they were very concerned about herbicide resistance in their fields. The results from this survey will help guide future research and outreach efforts to improve weed management strategies in Oregon’s field crops.
