The University of Nebraska-Lincoln Weed Management Field Day featured research and demonstrations by the Department of Agronomy and Horticulture Weed Science team and Nebraska Extension at Nebraska’s South Central Agricultural Laboratory near Clay Center on June 23.

Field day presentations were recorded and are available on the 2021 Weed Management Field Day site.

Demonstrations included several projects for weed control in corn, soybean and sorghum that included efficacy, crop safety and comparison of new herbicides for weed control. Herbicide programs and crop safety in multiple herbicide-resistant crop technologies were demonstrated, which included XtendFlex soybean (dicamba/glyphosate/glufosinate-resistant).

• Trey Stephens, agronomy master’s student, and Jenny Rees, Nebraska Extension educator, presented information on the interaction of planting green — no-till planting of the primary crop such as corn or soybean into actively growing cover crop such as cereal rye — and pre-emergence herbicides on weed control in soybean.
• Nathan Mueller, Nebraska Extension educator, discussed a project for weed management in corn in Nebraska’s unbiased comparison trial.
• Mandeep Singh, agronomy doctoral student, and William Neels, agronomy master’s student, demonstrated a project for control of XtendFlex soybean volunteers in corn with pre- and post-emergence herbicides.
• Shawn McDonald, agronomy master’s student, demonstrated a project for weed control in iGrowith and Inzen sorghum.
• Jasmine Masbauch, agronomy master’s student, led a project to evaluate atrazine alternatives for residual weed control in corn.
• Ramandeep Kaur, agronomy doctoral student, discussed a project of what not to do when multiple herbicide-resistant soybean traits coexist.

Amit Jhala, Department of Agronomy and Horticulture associate professor and Extension weed management specialist, organizes the large-scale Extension Field Days every year to demonstrate the results of weed management research to Nebraska growers, crop consultants, Extension educators, industry representatives and graduate students.

Others contributing to the successful field day included Michael Sindelar, assistant Extension educator with Nebraska Extension, and Eastern Nebraska Research & Extension Center’s research farm manager Michael Schlick, ag research technician Irvin Schleufer, office associate Sharon Hatchel, and summer students and South Central Ag Lab staff members.
