Lesion mimic

Posted by Russel Higgins -

My recent trip to campus for Agronomy day included a trip to the plant clinic in Turner Hall. Every time I take a trip to campus I try to learn something, that was the case when Suzanne Bissonnette and Stephanie Porter shared their expertise and identified lesion mimic on a corn sample from northern Illinois. http://web.extension....

How far to go to reach maturity in the northern Illinois corn crop?

Recently I've heard several agronomists who have broached the subject of an early (or even normal) frost and what impact that will have on our 2013 corn crop. Today I was asked how many days are yet needed to reach maturity. While some variation can be expected by variety and the weather conditions we experience in the remainder of the growing season, the following can be used as a guide....

University of Illinois Agronomy Day

Perfect weather for Agronomy Day at the South Farms on the University of Illinois campus. The very same weather that proved comfortable for those in attendance was also addressed as a concern for the 2013 crop. Dr. Emerson Nafziger  shared that the nighttime temperatures under 50 degrees would not  be a detriment to the corn crop final yield, provided the crop is allowed to reach maturity. The soy...

Despite observing the presence of Lady beetles for several weeks  (normally a good indicator of Sb aphids, a food source) I was unable to find aphids on the plants. That changed last Friday. While present in low numbers, Soybean aphids were easily found on plants in several trials at the NIARC. In a Bulletin artic...

Fungicide applications at the NIARC

Posted by Russel Higgins -

Unlike recent years, some disease pressure is showing up in both corn and soybean. At the NIARC we are continuing studies that evaluate the efficacy and economics of fungicide applications on both corn and soybean. Greg Steckel is spraying corn plots at R1 with a fungicide....

Back from Indiana

After a weekend at the Grundy County 4-H Fair it was off to West Lafayette to the campus of Purdue for the CSCAP annual meeting. We learned of the progress being made in the core platforms of sustainable corn production in a changing environment. We are two and a half years into the multi-disciplinary grant combining scientists and farmers to create a suite of practices for corn based systems that...
