Growers, crop consultants and educators are encouraged to attend Nebraska Extension's Weed Management Field Day from 8:30 a.m. to 1 p.m. July 1 at the South Central Agricultural Laboratory in Clay Center.

The field day will include on-site demonstrations of new technology and new herbicides for corn and soybeans. An early morning tour will focus on weed management in corn followed by a tour of weed management in soybeans. Field experiments will provide information for weed control options using several herbicide programs.

"Several new technologies are coming to the market, including Enlist Corn and Soybean, Roundup Ready 2 Xtend Soybean and Balance Bean," said Extension weed management specialist Amit Jhala.

The field day will provide the opportunity to see weed control and crop safety in new herbicide-resistant soybean varieties.
