Weed Management Field Days

weedmgmtdayGrowers, crop consultants and educators are encouraged to attend Nebraska Extension’s Weed Management Field Day from 8 a.m. to 1 p.m. June 29 at the South Central Agricultural Laboratory near Clay Center. The field day will include on-site demonstrations of new technology and new herbicides for corn, soybean and sorghum. An early morning tour will focus on weed management in soybeans followed by a tour of weed management in corn and sorghum. Field experiments will provide information for weed control options using several herbicide programs.

“Several new herbicides and technologies are coming to the market, including Enlist Corn and Soybean, Roundup Ready 2 Xtend Soybean, Balance Bean and INZEN sorghum” said Extension Weed Management Specialist Amit Jhala. The field day will provide an opportunity to identify several broadleaf and grass weeds commonly found in corn and soybean fields in Nebraska.

Three Certified Crop Advisor (CCA) Continuing Education Units are available in the integrated pest management category. There is no cost to attend the field day, but participants are asked to register at http://agronomy.unl.edu/weedresistmgt. The South Central Agricultural Laboratory is five miles west of the intersection of Highways 14 and 6, or 13 miles east of Hastings on Highway 6.amaranthGrowers, crop consultants and educators interested in management of herbicide-resistant Palmer amaranth are encouraged to attend Nebraska Extension’s Field Day, supported by the Nebraska Corn Board, from 8:30 a.m. to 1:30 p.m. July 12 near Shickley.  Palmer amaranth is a member of the pigweed family and is one of the most troublesome weeds in seed cornfields because of its resistance to atrazine and HPPD inhibitors. Greenhouse dose-response studies have confirmed resistance when atrazine and HPPD inhibitors were applied post-emergence. Palmer amaranth is of particular concern in south-central Nebraska because of its proximity to intense seed corn production, which is heavily reliant on these herbicides for weed.

At the field day, experiments will demonstrate how to control Palmer amaranth in field and seed corn production fields in Nebraska. Keynote speaker, Jason Norsworthy will share his experiences for management of glyphosate-resistant Palmer amaranth. Norsworthy is a professor and endowed chair of weed science at the University of Arkansas.

Three CCA credits will be available. There is no cost to attend the field day. However, pre-registration is required before 3 p.m. on July 11. To register, visit http://agronomy.unl.edu/weedresistmgt.

Directions to the Field Day: From Geneva, go south on Highway 81 for seven miles. Turn west onto Highway 74 for 12 miles. Turn north on Road 2 for three miles. Turn west on Road Q for 0.1 mile. The farm field is on the north side of Road Q.
