There are two good field days worth attending close to our area. One is the Herbicide-Resistant Weed Field Days on August 6 and 7. The other is the Soybean Cyst Nematode Field Day on August 22.
Management of herbicide-resistant weeds will be the focus of field days August 6 at David City and August 7 at Fremont. David City: From Hwy 15 in David City, turn west on East A St., then continue west for 2 blocks and look for the UNL field sign. Fremont: Parking is not available at the site. Please park in the Fremont Tractor Supply parking lot (next to Walmart), and shuttle buses will transport you the 1.5 miles to the field day site.
"Herbicide-resistant weeds are a real problem here in Nebraska. Folks should take the time to make an investment in management practices that reduce the potential for resistance," said Lowell Sandell, a Weed Science Extension Educator.
Each field day will begin at 9 a.m. and end at 1:30 p.m. following lunch. The event is free but preregistration is required by Friday, August 2. Register online at http://agronomy.unl.edu/
Field day topics include: Glyphosate Dose Response: See how resistant weeds respond to increasing rates of glyphosate- Management Systems: Study various herbicide programs and their effectiveness in controlling glyphosate-resistant weed populations- Liberty Link Soybean: See how Liberty Link Systems can be used to sustainably manage weeds- Dicamba-Resistant Soybean (Fremont only): View demonstrations of how dicamba-resistant soybean can provide another postemergence tool for weed management- and Carrier Rate: See how carrier rate impacts herbicides. This stop will also address the importance of effective herbicide applications to manage the development of weed resistance.
The Soybean Cyst Nematode Field day is August 22 near Madison at the Matt King Farm. From Madison: Go 12 miles west on Highway 32, (or 4 miles east of Highway 45), then 1 mile south on 541st Ave, and 0.25 mile east on 827th Road. The event is on the north side.

SCN often goes undetected in the field. Yield losses of 20-30% have been documented in Nebraska fields with no aboveground symptoms. If SCN caused holes, lesions, spots, or other plant abnormalities, it would be much easier to convince producers to test for and manage it. However, infested plants usually look healthy. Often, the first indication of a problem is when soybean yields level off or even start to drop while corn or other crop yields in the same field continue to improve.
At each SCN Management Field Day site, you will be able to: see SCN resistant and susceptible soybean varieties in infested fields; examine cysts on soybean roots; learn how to identify and manage SCN infestations; receive bags for free SCN analyses—a $25/bag value; get answers to your SCN questions; and enjoy a complimentary meal and visit informally with experts.
The Soybean Cyst Nematode Management Field Days are presented by UNL Extension with support from the Nebraska Soybean Board.
