Crazy top, named for the odd formations of the leaves or tassel due to hormonal effects of the disease, is typically found on corn plants that were submerged for a few days early in the growing season. A description of the disease and of its symptoms can be found at http://bulletin.ipm.illinois.edu/pastpest/articles/200220c.html
While a lot of corn was submerged during early growth in Illinois this year, we haven’t been seeing a lot of this disease.…

Last week, I visited all of the University of Illinois corn variety trials in the northern half of the state. Gray leaf spot and northern leaf blight were beginning to appear in most of the locations, but were the most obvious at the trial located near Perry, IL (Pike County).
With the amount of rainfall received in the past few weeks, it is not surprising that these diseases were beginning to appear. Since hybrids differ in their level of susceptibility to these diseases,…
Stripe rust of wheat has been observed in different parts of Illinois within the last week. Although some varieties have very good resistance to stripe rust, there are still several varieties that are susceptible. Stripe rust is able to flourish under the cooler temperatures we’ve had over the last few days. With rain in the forecast in parts of the state over the next few days, favorable conditions for this disease likely will continue.
Although some wheat fields in the state are already past the critical period for applying a fungicide for protection against Fusarium head blight (a.k.a.…
What pests will the 2015 growing season feature? Let the Plant Clinic help you diagnose them. Samples havePreview been gradually filling up the lab here at the Clinic in our 40th year of operation. On the field front, there have been concerns with root and virus disease diagnosis in wheat. On the home landscape front, there has been a steady influx of fungal disease.

As the weather begins to warm up, wheat is beginning to grow at a faster pace. Symptoms of some diseases also are beginning to appear or will likely be appearing soon. Below are some diseases to look for right now.
Stagonospora and Septoria leaf blotch: Although caused by two different pathogens, symptoms of these two foliar diseases look very similar and both can be managed with an appropriate foliar fungicide application. Most results from University of Illinois wheat foliar fungicide trials conducted since 2008 have shown that an application of an effective fungicide for control of Fusarium head blight (scab) when wheat is beginning to flower also provides good protection against common foliar fungal diseases on the flag leaf. …
