Currently, most small grains are approaching jointing or just past jointing in many parts of the state. Now is the time that you most likely will start to see early season viral diseases in some fields, specifically Wheat Soilborne Mosaic Virus and Wheat Spindle Streak Virus.…
Last month (March 2018) we used data from 2017 N rate response trials to update the N rate calculator that provides best-estimate N rate guidelines for different regions and previous crops (corn or soybean) in Illinois. The updating process, which is currently being done by spring each year in Illinois, involves adding the new data and taking out some of the older data.
Many people understand the idea of using data from previous research to try to predict how a management factor will work the next time (in this case,…
I received notice of stripe rust in S. Illinois today. Stripe rust is an important disease affecting wheat. Please find an article on this disease and management by clicking here.
If you locate stripe rust in your field please tweet a picture to me (@ILplantdoc) or email (nathank@illinois.edu) with the wheat variety, growth stage, and approximate percent of field infected. This information will be useful to IL wheat producers this year and in upcoming seasons.…

Stripe rust was reported out of Gallatin County this morning. It is important that you understand this disease and how it works, so that you can make the appropriate management decisions. This article will discuss the pathogen that causes the disease, symptoms, and some general management guidelines.…
If the old saying that rain on Easter means that it will rain on the next seven Sundays applies to snow, we’re in trouble – it snowed across a wide swath of Illinois on Easter Sunday (April 1) and also on April 8.
We had enough dry weather in March to allow some ammonia to go on early, but there has been little opportunity for field work over the last six weeks. Rainfall over the past month has been below normal for the northern third of Illinois and above-normal in the southern half of the state,…

It is a little early to be discussing Fusarium head blight (FHB) , but it is something that always seems to come up in conversation. Currently our wheat has yet to to hit jointing, and it will be a while before we are at the flowering stage. …
Beginning in 1949, a conference was organized by faculty and staff from several departments at the University of Illinois to provide clientele and stakeholders with the latest pest management research and recommendations. The conference was brought into existence by Dr. H.B. “Pete” Petty, the first extension entomologist with the Cooperative Extension Service at the University of Illinois, to meet the educational needs of Illinois pest management practitioners. From its inception in 1949 through 1986, the conference was known as the Illinois Custom Spray Operators’ Training School (often referred to as Spray School),…
It’s difficult to recall the debut of a weed management technology that generated more divisiveness than the 2017 introduction of dicamba-resistant soybean varieties and the accompanying use of dicamba. Damage to off-target vegetation from myriad sources of exposure resulted in not only monetary losses, but also untold costs to professional and personal relationships. Trust that took years to build was damaged or lost in the span of one growing season. This includes the public trust in pesticide use.…
I wrote a short article here about a month ago asking for everyone’s cooperation on a project in which we (Corn Belt states) are gathering field-level information on soybean fields to feed into a study, funded (with soybean checkoff dollars) by the North Central Soybean Research Program, looking at weather, soil, and management effects soybean yield over the Corn Belt.
While we got some response to that article, we have so far gathered information on less than half the fields in Illinois that we,…

Rootworm management is a yearly consideration for most corn producers in central and northern Illinois. Western corn rootworm (Fig. 1) is the primary pest species throughout most of the state, but areas in northern IL can experience pest pressure from the northern corn rootworm (Fig. 2) as well. Adult population densities have been low in recent years compared with historical averages, although they did creep up a bit in 2017.…
