Considerations for fungicide management of Fusarium head blight of wheat

  • May 9, 2014

Wheat plants are now beginning to head out and flower in parts of southern Illinois. During this critical time of wheat development, wheat becomes susceptible to infection by Fusarium graminearum, the causal agent of Fusarium head blight (FHB; also known as scab) (Fig. 1). This disease can cause reduced grain yield, test weight, and quality. In addition, the fungus can produce toxins that will contaminate grain such as deoxynivalenol (DON; also known as vomitoxin).…

Visualizing the growth rate of Palmer amaranth

  • April 28, 2014

Recently, the weed science program at the University of Illinois published recommendations for the management of Palmer amaranth in Illinois agronomic crops.  One particular recommendation emphasizes the need for timely application of foliar-applied herbicides; in particular, foliar-applied herbicides must be applied before Palmer amaranth plants are taller than four inches.  Most weed management practitioners are very familiar with the growth rates of waterhemp and many other weed species, but perhaps are less familiar with the growth rate of Palmer amaranth.…

Terminating cover crops

  • April 16, 2014

The number of acres in Illinois seeded with various cover crops has increased during the past few seasons.  Those cover crops that do not winter kill are usually controlled the following spring with herbicides.  Dr. Bob Hartzler, extension weed scientist at Iowa State University, recently published an excellent article in which he describes several factors that can impact the performance of spring-applied herbicides used to terminate cover crops.  We sincerely appreciate Dr. Hartzler’s willingness to allow us to reproduce his article which follows.…

Management of Palmer amaranth in Illinois

  • March 27, 2014

Palmer amaranth is a weed species that must be thoughtfully and carefully managed; simply attempting to control Palmer amaranth often leads to ineffective herbicide applications, substantial crop yield loss, and increasing weed infestations.  Ignored or otherwise not effectively managed, Palmer amaranth can reduce corn and soybean yield to near zero.  The threat of Palmer amaranth during the 2014 growing season is very real across a large portion of Illinois.
In January 2014, the weed science program at the University of Illinois developed recommendations for management of Palmer amaranth in agronomic crops. …

Rescheduled Meetings of the 2014 University of Illinois Corn & Soybean Classic

  • January 7, 2014

Nature reminded us earlier this week that even though we select meeting dates well in advance, the weather often determines whether or not we can actually hold the meeting.  Our long streak of good fortune came to an end this week as the adverse weather and road conditions forced us to reschedule two Classic meetings.  The Classic meeting at the Urbana I Hotel and Conference Center originally scheduled for January 6 has been rescheduled for January 28. …
