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.

...Moth counts ramped up dramatically during Week 2 of the moth trapping network (April 7 to April 13), although we often get large flights with spring storm systems in April. Despite the low captures reported during the first official week, 70 total black cutworm (BCW) moths were reported last...
Timing is crucial for spring planting. Planting too early can expose young stands to damaging frost, while planting too late can lead to greater potato leaf hopper and weed pressures. Establishing a vigorous alfalfa stand is pivotal for future production, forage quality, and minimizing weed...

Given the dry conditions that prevailed Iowa in 2023, there will be herbicide carryover in 2024. Suspect herbicides that are likely to carryover include, but are not limited to atrazine, clopyralid, and the various HPPD inhibitor herbicides. Specifically, the accuracy, evenness, and timing (i.e...
Iowa soils can hold 9-12 inches of water in the soil profile and most parts of Iowa have shallow water tables at about 4-7 feet depth. These two sources of water, together with the precipitation, provide water for crop production. Typically, a 250 bu/ac corn yield requires about...
Planting, in my opinion, is THE most important field operation. Planting in the optimal planting window and into good seedbed conditions will set the plant up for rapid growth and high yield potential. With planters beginning to move or sitting in waiting for better...
Key Points
- El Nino transitioning to La Nina during this summer; increased risk of heat
- Still need more moisture for streamflow recovery in many areas of the state, particularly southern and eastern parts of the state
- Good chances for the planting season to be...
I have been observing, and also receiving phone calls and e-mails about, purple weeds in untilled fields. If you observe such an area, the weeds are probably either purple deadnettle (Lamium purpureum) or henbit (Lamium amplexicaule) or a mixture of the two. They are very...
A few more farmers are switching to a high-speed planter when upgrading or trading planters. A few reasons they report for switching to the high-speed planter include:
The 2024 moth trapping season is underway, and our volunteers began placing traps the week of March 24. Black cutworm (BCW) monitoring is a long-standing project in Iowa to detect moths migrating from southern overwintering sites each spring. By monitoring adult black cutworms, we can provide...

Over the last 10 days, precipitation totals across the state have varied with less precipitation falling in the western and northern part of the state and heavier amounts falling in the east-central and southeast part of the state.
With the announcements of water usage restrictions in parts of Iowa, pesticide applicators may need to use alternative water sources for their pesticide...
During the past 90 days, temperatures have been warmer than average, keeping soils from freezing and allowing much needed precipitation to infiltrate into the soil. Despite accumulated precipitation across the state being greater than average for the past 90 days, soil moisture is still lacking...
AMES, Iowa – Planting season varies wildly from year to year and technology is always changing. Cool and wet conditions can dramatically delay planting. When soil conditions are remarkably dry, getting seed in the soil at the correct depth is a challenge. But just as each planting season is...

The spring planting season in Iowa is quickly approaching. Therefore, it is critical to prepare now and check a few items when starting each field. While it takes time to check these items, field research has shown that getting the correct gauge wheel pressure (downforce pressure) to help create...
The spring planting season in Iowa will start soon, so it is time to make a list of items to check and get completed before we go to the field. As we all know, planting the seed at the right time, right seed depth, and acceptable soil conditions is critical to giving the crop the best starting...

It most certainly has been a strange winter with very little moisture. This fact, combined with a multi-year drought has people concerned for spring planting. Most farmers I have talked to this winter have shared concerns about not only the lack of precipitation, but the lack of soil moisture....
High February temperatures have prompted many alfalfa fields across the state to initiate greening up over the past couple of weeks (Figure 1). However, temperatures then plummeted (9°F) earlier this week, likely resulting in the demise of the new growth. But the more pressing question is...
