Dr Laura Jesse Iles directs the North Central IPM Center. Dr. Iles has earned B.S. (Animal Ecology), M.S. (Entomology), and Ph.D. (Co-major in Entomology and Ecology and Evolutionary Biology) degrees, all from Iowa State University. In addition to directing the PIDC, Dr Iles serves as the entomology diagnostician. As part of the ISU Integrated Pest Management Program Dr. Iles provides educational training in the broad areas of consumer horticulture, biological control, and invasive insect management.
Dr. Sotirios Archontoulis is an assistant professor of integrated cropping systems at the Department of Agronomy. His main research interests involve understanding complex Genotype by Management by Environment interactions and modeling various components of the soil-plant-atmosphere continuum. Dr. Archontoulis's overall goal is to investigate practices that can increase the efficiency of system by means of increasing crop yields and simultaneously decreasing inputs or losses such as water and nitrogen. His approach combines field experimentation and use of mechanistic simulations models.

I’m a “lumper” and don’t try too hard to distinguish feeding by species. Replicated data over multiple...
Iowa Soil Health Workshop Planned for August 4th
Topics will include fertility tests, cover crops, and evaluating soil health with a microscope
A soil health workshop will be held Aug. 4 at Iowa State University’s Field Extension Education...
While there was some much-needed rain across the state last week, the rain also brought some wind with it as well that resulted in lodged or leaning corn as well as some greensnap in fields. In addition to the wind damage, herbicide injury in soybeans, tar spot concerns, and Japanese beetles...
Western and northern corn rootworm are serious pests of corn throughout the Corn Belt. We recommend that farmers scout every cornfield every year, regardless of the management tactic(s) used, to evaluate management decisions and prepare for next year. It is a good idea to scout for larvae early...
In the evening hours of July 5, 2022, a derecho moved through South Dakota into northwest Iowa. Gusts in South Dakota were as high as 99 mph with winds that lasted up to 20 minutes. The path of the storm’s length was about 600 miles. A...

Herbicide injury in soybean, Japanese beetles, potato leafhoppers in alfalfa, tar spot being found in Marshall and Jones counties (and some additional counties since) at low levels, and some hail damage in NE Iowa were some of the issues observed by ISU Extension field agronomists this last week...
In pathology, we joke that to control a disease, just put a research plot out, and you’re guaranteed no disease. A couple of days ago I blogged about tar spot, hoping for a similar effect. Alas,...
While most areas received some needed rain last week, some areas in Western Iowa continue to miss out on the rain or get minimal amounts of rain and it’s starting to show more in the crops. Getting out in the fields, some pests or issues observed by...
Are you using the Tarspotter app this year? If you are, you may have noticed that the forecast for tarspot is high for Iowa. In addition, The Cruz Lab in Indiana tweeted they had found tar...
Isolated hail and wind damage, iron deficiency chlorosis, herbicide damage, and moisture stress (too much or too little depending upon the area) were some of the big issues that ISU Extension field agronomists noted in fields across the state. Read on to for more specifics about what’s happening...
Today, while scouting for bean leaf beetle south of Ames, my lab found a few early vegetative plants with soybean aphid. Actually, it was Ashley Dean who found them. It was the ants moving on plants that caught her eye. Taking a closer look revealed a few small aphid colonies feeding on the...
While in westcentral Iowa yesterday setting up some small plot experiments, I got distracted by a long stretch of grass alongside a cornfield. I noticed some “deadheads” among the green plants and decided to dig a little deeper.
