Palmer amaranth

Growers, crop consultants and extension educators interested in management of atrazine/glyphosate-resistant Palmer amaranth are encouraged to attend Nebraska Extension's field day, supported by the Nebraska Corn Board, from 9 a.m. to 1 p.m. June 30 near Carleton.

Lincoln, Neb. —Growers, crop consultants and extension educators interested in management of atrazine/glyphosate-resistant Palmer amaranth are encouraged to attend Nebraska Extension's field day, supported by the Nebraska Corn Board, from 9 a.m. to 1 p.m. June 30 near Carleton.

Palmer amaranth is a member of the pigweed family and is one of the most troublesome weeds in corn and soybean production fields in Nebraska because of its resistance to atrazine/glyphosate and ALS-inhibiting herbicides. Greenhouse dose-response studies have confirmed resistance when glyphosate was applied even at higher rates.

At the field day, experiments will demonstrate how to control atrazine/glyphosate-resistant Palmer amaranth in Roundup Ready/LibertyLink corn, Enlist corn, and non-GMO white corn in Nebraska.

Three certified crop adviser credits will be available.

There is no cost to attend the field day. However, pre-registration is required before 3 p.m. on June 28. To register, visit http://agronomy.unl.edu/palmer.

Directions to the field day: From Geneva, go south on Hwy 81 for 14.6 miles, turn west onto Hwy 4 for 5.3 miles. Site is located on the south side of Hwy 4 between C St. and Renwick St. in Carleton. GPS coordinates: 40°18’24.7”N 97°40’29.0”W.
