Weed Management Videos Available From NDSU Extension

The videos focus on weed identification and herbicide site-of-action.

Producers, crop advisers and others interested in weed management have an opportunity to learn more through three videos North Dakota State University Extension has developed.

The videos are a partial substitute for the one-day Crop Management Field School that NDSU Extension normally holds at the Carrington Research Extension Center to provide field training for crop advisers and farmers on various crop production subjects. The field school was not conducted this summer due to the COVID-19 pandemic.

“Based on participant evaluations from past schools, weed identification and herbicide site-of-action have been highly rated subjects for usefulness,” says Greg Endres, Extension cropping systems specialist at the center. “Thus, live weed exhibits and a herbicide site-of-action field demonstration were prepared as resources for the video programs.

“Identifying weeds is the first step in management,” he adds. “Pigweeds and numerous grasses are difficult to control, especially because most have herbicide resistance. The herbicide site-of-action information is useful for planning herbicide use strategies for herbicide-resistant weeds and as an aid in solving field crop problems associated with residual herbicides in soil or off-target herbicide movement.”

The video topics and NDSU Extension presenters are:

  • Pigweed identification: Palmer amaranth, Powell amaranth, waterhemp and redroot pigweed - Joe Ikley, Extension weed specialist
  • Annual and winter annual grass identification - Endres
  • Typical plant injury symptoms exhibited by crops and weeds with application of herbicides selected from eight site-of-action groups - Ikley

The three videos can be viewed from a smartphone or computer at https://www.ag.ndsu.edu/CarringtonREC/crop-management-field-school-2020.
