Considerations for fungicide management of Fusarium head blight of wheat

  • May 9, 2014

  • Aaron Hager

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).…

Palmer amaranth management recommendations

  • May 5, 2014

  • Aaron Hager

A few weeks ago we published recommendations for the management of Palmer amaranth in Illinois agronomic crops.  Those recommendations are now available in a file format that can be downloaded and printed.  Please don’t hesitate contact me if you have any questions or problems with the file.

Another Look at Corn Planting Date Response

  • May 2, 2014

  • Emerson Nafziger

As we head into May, Illinois is ahead of most of the rest of the Corn Belt, with 32% of the corn crop planted here by April 27, close to the 33% that was planted by that date averaged over the past 5 years. Only 19% of the US corn crop was planted by April 27, and states to the north and east of Illinois were in single digits. It is wet in much of the Corn Belt now,…

Running On-Farm Strip Trials

  • May 1, 2014

  • Emerson Nafziger

On April 16 I posted an article http://bulletin.ipm.illinois.edu/?p=1966 on the use of nitrogen fertilizer on soybean, mentioning at the end of the article that this would be a good thing to test in on-farm trials. Here I’ll provide a little background and a brief description of how to go about doing such a trial.
Background: dealing with variability
If there were no variability in yields (or soils) going across a field, a single strip of N fertilizer (or without N while applying N to the rest of the field) would measure the effect.…

Visualizing the growth rate of Palmer amaranth

  • April 28, 2014

  • Aaron Hager

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.…

Black Cutworm – Projected Cutting Dates for Some Illinois Counties

  • April 28, 2014

  • Michael Gray

Significant flights of black cutworm moths were reported in several counties of Illinois during mid-April. Based upon these captures of moths in pheromone traps, projected cutting dates are offered for the following counties: Champaign (May 20), Fayette (May 11), Logan (May 14), Madison (May 11), Pike (May 17), and Warren (May 18). Fields most at risk to economic infestations include those that are planted late and infested with winter annuals. Weedy fields are often targeted for egg laying by these strong migratory moths.…

Ready for Samples at the University of Illinois Plant Clinic

  • April 24, 2014

  • Suzanne Bissonnette

Welcome to another Diagnostics season! Samples have been steadily appearing this spring here at the Clinic in our 39th year of operation. On the field front, there have been concerns with virus disease diagnosis in wheat. On the home landscape front, there is a mountain of winter kill and windburn injury from the harsh winter just past.
The University of Illinois Plant Clinic began year-round operation in the fall of 2011. Our new location is in Jonathan Baldwin Turner Hall on the south end of the Urbana campus.…
