A follow‐up survey to assess stakeholders’ perspectives on weed management challenges and current practices in Nebraska, USA

Abstract Stakeholders across the state of Nebraska, USA, were surveyed in 2019–2020 to assess problem weeds and weed management practices agronomic crops. A total 420 complete responses obtained four Nebraska districts (Northeast, Panhandle, Southeast, West Central). Accumulated state, 65.5% farmed or scouted crop ground was under no‐till production, with major crops being corn soybean representing 39.3% 30.7% production area, respectively. Palmer amaranth, horseweed, waterhemp, kochia, giant ragweed ranked most problematic weeds. In a 2014–2015 survey, amaranth sixth weed. The used preplant herbicides 2,4‐D, glyphosate, dicamba survey. Atrazine applied alone mixture acetochlor, bicyclopyrone, clopyralid, mesotrione, S ‐metolachlor pre‐emergence (PRE) corn, whereas PRE metribuzin/sulfentrazone, flumioxazin/pyroxasulfone, chloransulam‐methyl/sulfentrazone. Like previous glyphosate frequent choice survey respondents as post‐emergence (POST) herbicide glyphosate‐resistant soybean, while 2,4‐D POST grain sorghum wheat. Most (77%) aware new multiple herbicide‐resistant crops, 86% listed physical drift volatility dicamba/2,4‐D primary concern. Twenty‐three percent identified integrated pest research extension priority for profitable Nebraska.
