Earlier this year, Michigan became the sixteenth state in the country to confirm a case of glyphosate-resistant horseweed when it was discovered in a Christmas tree plantation.

Aaron Hager of the University of Illinois Extension Service cautions that wheat stubble fields in which no second crop is planted often become populated with summer annual (and sometimes perennial) weed species. No-tillers should not allow these plants to reach maturity and produce seed, he says.

When strip-tilling, it is essential to have the proper planting depth and use trash whippers to move remaining residue off the row area. I also recommend a split application of nitrogen and the use of readily available nitrogen sources such as UAN or ammonium nitrate.

New rate recommendations for Headline fungicide have been permitted by the EPA for control of all key disease in corn, according to its manufacturer, BASF.

Researchers in Tennessee are looking at the feasibility of no-tilling switchgrass, a warm-season perennial that can grow up to 7 feet in height, as raw material for biofuels and an alternative to corn-based ethanol.

Having invested in the latest sprayer technologies, cereal grain growers are gearing up to do a better job of applying pesticides — starting this fall with winter wheat.

With concerns continuing to develop over glyphosate weed resistance in no-tilled crops, weed scientists keep suggesting that growers start using LibertyLink and Clearfield traits that offer alter- native herbicide modes of action.

Despite the fact that U.S. Environmental Protection Agency officials estimate that growing corn without atrazine could cost no-tillers as much as $28 an acre due to reduced yields and the need for more expensive herbicides, you might be in danger of losing this long-term weed control chemical product.
