Dr. Erin Hodgson started working in the Department of Entomology, now the Department of Plant Pathology, Entomology, and Microbiology, at Iowa State University in 2009. She is a professor with extension and research responsibilities in corn and soybeans. She has a general background in integrated pest management (IPM) for field crops. Dr. Hodgson's current extension and research programs are focused on improving corn and soybean production by using IPM tactics to protect yield and increase overall farmer profits. Among other projects, she oversees insecticide efficacy evaluations for soybean aphids, Japanese beetles, and aphids in corn. Erin also helps manage emerging field crop pests and invasive species.

Dr. Mark Licht is an associate professor and extension cropping systems specialist with Iowa State University Extension and Outreach. His extension, research and teaching program is focused on how to holistically manage Iowa cropping systems to achieve productivity, profitability and environmental goals. Research is centered around varied aspects of soybean, corn and cover crop management as well as agronomic implications of precision technologies.
Meaghan Anderson is a field agronomist in central Iowa and an extension field specialist at Iowa State University Extension and Outreach. Educational programming is available for farmers, agribusinesses, pesticide applicators, certified crop advisors, and other individuals interested in crop production.
Areas of expertise include weed management, weed biology, cover crops, corn and soybean management, and integrated pest management.

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.

Grain needs to be checked regularly, preferably at least every two weeks, through the winter so that a problem can be detected before it becomes a disaster to deal with. Below are some tips to help manage stored grain during the winter:
Iowa State University Extension and Outreach has completed their fall survey of subsoil moisture in northwest Iowa. The survey provides a current and historical perspective on subsoil moisture levels. Soil moisture is sampled to a depth of five foot in one-foot increments at pre-determined...
It’s the time of year when farmers and retailers turn to thoughts about next year’s growing season, including fall anhydrous ammonia (NH3) applications for the next year’s corn crop. See Is it...
The time for fall application of anhydrous ammonia and manure is approaching, but we may not be there yet. This blog has a few things to keep in mind this fall and links to some good references.
While soybean harvest seems to be winding down, we need to be carefully monitoring the soil...
Corn field edge effect has once again show up in Iowa. It is raising questions about what is causing it. In 2019 and 2020, I was able to conduct some exploratory data collection to learn more about the phenomenon.
What is it? Edge effect in corn is where the outside rows...
With harvest underway across the state, check out what ISU Extension and Outreach field agronomists are hearing regarding how harvest is going, how are the crops yielding, and what types of end-of-the season issues they are receiving questions on.

Fall is in the air and harvest is starting up across Iowa. It has been noted soybean are holding onto their leaves. This green bean effect is more often thought of as green stems, however, this year there are more leaves and petioles staying green and attached to the main stem. Take note this...
Safety should be a major concern for all farmers during harvest, but as the season goes on, it can be easy to miss details or neglect safe practices that can put you or others at risk. Here are six simple safety tips to maintain throughout the season to keep yourself and your crew out of harm’s...
All it takes to start a fire is just a spark from an engine, an overheated bearing on a combine, or a hot exhaust manifold where some dirt and dry plant material have gathered. Dry plant residue, dusty conditions, low humidity levels and strong winds are a recipe for combine and field fires....
It’s hard to believe another growing season has come and is almost gone. 2022 has had its share of challenges: a wet start, drought, corn root worm, soybean gall midge, pigweed, and (my favorite) tar spot. And now, as we approach harvest, we face final challenges like ear and crown rot.

As the growing season winds down, ISU Extension field agronomists share what they are seeing out in fields or are getting questions on. Some of the common observations include the drought stress resulting in crops shutting down early, tar spot becoming more prevalent in fields, sudden death...
Again this August, I joined my colleague Patrick Hatting, Farm Management Specialist for central Iowa, and checked several Polk County corn fields to make yield estimates. After R3 (milk stage) is a great time to venture...
Before the rush of harvest gets here, take some time to get your grain bins ready for a new crop. The first step in minimizing grain spoilage from insects is to start with a clean bin. Grain-feeding pests can survive on residual grain, broken kernels, fines, foreign material, and molds...
As we enter the time for aerial and broadcast overseeding of cover crops, now is a good time to think about how current weather, soil and crop conditions might affect things. First and foremost, there are parts of the state that are very dry and others that have been getting timely rains....
I continue to receive tar spot reports from across Iowa. Given the moisture we have had the past couple of weeks and the growth stage of the crop, this is not surprising. Tar spot development is favored by leaf moisture. As the growing season...
Several labs in the Midwest have been monitoring the distribution of soybean gall midge in Iowa since 2018. Last year, we sampled many counties in western Iowa but only confirmed three new counties. This year, we focused on the counties just east of the distribution in 2021 and were able to...
