Marestail Control Prior to Planting

Marestail can be one of the most challenging weeds to control prior to planting no-till soybean.  Already this season some have reported poor marestail control following applications of glyphosate plus 2,4-D.  Poor control can be caused by several factors, including large plant size and resistance to glyphosate. … Read more

Rust pathogens are obligate parasites, meaning that they need a living host in order to survive.… Read more

Planting Date: Corn or Soybean First?

Corn planting in Illinois has gotten into gear over the past week, with 12 percent of the state’s crop planted by April 17. That’s close to the planting pace of a year ago, and is behind the 5-year average only because that average includes 2012, when nearly half of the state’s corn crop was planted by mid-April.… Read more

Spring Nitrogen Management for Corn

Even though the price of nitrogen fertilizer has dropped some in the past year, the lower price of corn means that decisions about N management need to be made carefully, with an eye towards maximizing the return to this critically important input.… Read more

Is Fall-Applied Nitrogen Still Present?

The pattern of warmer and wetter than usual weather this past winter has changed some in the past two months, but hopes for a warm, dry, early spring have faded as well. Concerns remain about how much fall-applied N might have been lost and about whether and how this should change how we manage N this spring.… Read more

Cover Crop Termination

The following information about cover crop termination is taken from the 2016 Weed Control Guide for Ohio, Indiana and Illinois.  The information was originally written by extension weed scientists at Purdue University.

Cover crops are unique in that most are planted primarily to reduce soil erosion and otherwise enhance soil quality, and are not harvested for their seed, fruit, or forage (although some are grazed or used as forage).… Read more

A New Way to Look at Soybean Management

The University of Illinois is part of a large, multi-state research project funded by the North Central Soybean Research Program (funded by state checkoff programs) to look at effects of weather, soils, and management on soybean yields.… Read more

Dicamba-resistant soybean varieties

On February 3, Monsanto announced its commercial launch plans for soybean varieties resistant to the herbicides dicamba and glyphosate (designated Roundup Ready 2 Xtend varieties). This announcement followed China’s decision to import grain from these varieties.… Read more
