MACOMB, IL -- The Western Illinois University agriculture department is sponsoring a Herbicide Plot Tour beginning at 1 p.m. Thursday, June 26 at the WIU Agronomy Field Laboratory on Ember Road, located immediately north of the WIU Harry Mussatto Golf Course on Tower Road. The event is open free to the public.

According to Gordon Roskamp, WIU agriculture professor and field plot coordinator, topics to be discussed include:

• "Glyphosate-resistant waterhemp in western Illinois" by Mike Roegge, crops educator for the Adams/Brown counties Extension Office.

• "Foliar fungicides resistance" by Matt Montgomery, Mason County extension director.

• "Asian Soybean Rust and other diseases of western Illinois field crops" by Loretta Ortiz-Ribbing, pathologist and extension specialists in the Macomb Extension Office.

• "Monsanto's development of new corn hybrids and soybean varieties to control pests and meet consumer demands" by Kurt Maertens, Monsanto development representative.

• "Corn Nematodes and Soybean Cyst Nematodes" by Terry Niblack, University of Illinois extension specialist, plant pathology department of crop sciences.

• "Seed treatment chemicals to protect from soil pathogens, insect pests and growth enhancement" by Hank Mager, seed treatment specialist with Bayer.

• "Avicta seed treatment in cotton to cotton nematodes" by Jeff Kaiser, product development representative with Syngenta.

• "Nitrogen trials comparing the optimum rate of nitrogen in weed-free fields vs. fields that receive postemergence herbicides" by Roskamp.

• "Canola trials and potential for biofuels" by Fred Iutzi, agriculture technician in Western's Alternate Crops program.

More than 25 weed control experiments have been established in strip-till and mulch-till. Various herbicides were applied in the fall, early preplant, preemergence and postemergence. New herbicides include Halex GT, Impact, Laudis, Prefix, Prequel, Sequence, Status, SureStart, Sonic/Authority First and Valor XLT. Nearly all of the current recommended weed control programs are on display in fields with relatively heavy weed pressure, Roskamp added.

Company sales and product-development representatives will be on hand with the latest information on pest control strategies to maximize profits. For more information contact Roskamp at 309/298-1569 or the WIU agriculture department at 309/298-1080.
