Amit Jhala | Nebraska Extension Weed Management Specialist
Amit Jhala, Nebraska Extension weed management specialist, discusses management of glyphosate-resistant weeds in Nebraska soybean at Nebraska Extension’s 2019 Weed Management Field Day June 26 at the University of Nebraska–Lincoln’s South Central Agricultural Laboratory near Clay Center.
University of Nebraska–Lincoln weed management research was featured and demonstrated at Nebraska Extension’s 2019 Weed Management Field Day on June 26 at the university’s South Central Agricultural Laboratory (SCAL) near Clay Center, Nebraska. Amit Jhala, associate professor and extension weed management specialist organized and led the tour.
A total of 158 attended the field day, including growers, crop consultants, administrators, extension educators, graduate students, industry representatives and other clientele.
Nebraska Weed Science team members demonstrated several projects for weed control in corn, soybean and popcorn 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. This included XtendFlex soybean (dicamba/glyphosate/glufosinate-resistant) and a project lead by graduate student Jasmine Misbauch known as “Alite 27 soybean” (glyphosate/glufosinate/isoxaflutole-resistant).
Several herbicide programs were compared for weed control in corn and soybean in the university’s unbiased comparison trials. Doctoral student Ethann Barnes demonstrated a project for weed control in corn with herbicides with multiple effective site-of-action. Graduate student Adam Striegel demonstrated how to control volunteer corn in Enlist corn. Shawn McDonald, a graduate student, demonstrated a project for weed control in corn with dicamba with and without ammonium sulfate. Graduate student Samantha Isaacson led a project for control of johnsongrass and foxtail species in popcorn. Invited speaker Bob Klein discussed best management practices for reducing herbicide drift. Jose Henrique Sanctis, a graduate student, discussed a project about glyphosate alternatives and timing for terminating cereal rye before and after planting soybean. Invited speaker Andrea Basche, assistant professor of agronomy and horticulture, discussed the role of cover crops for weed suppression in Nebraska corn and soybean cropping systems.
The Weed Science Team would like to thank Michael Schlick, Irvin Schleufer, Jared Stander, Will Neel, Adam Leise, summer students and staff members of the South Central Ag Lab for their help. The team also thanks Nebraska Extension Educators Jenny Rees, Ron Seymour and Tood Whitney for their help and Wendy Morrissey, Connie Hansen and Lana Johnson for their assistance with registration and promotion.
