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.

The first ‘official’ finding of Palmer amaranth in Iowa was August 2013 in Harrison County. Shortly thereafter the weed was identified in Muscatine, Fremont and Page County. These infestations were likely due to Palmer amaranth seed being transported on equipment/trucks involved in crop...
Frost injury occurred Saturday May 29 across much of the area. Radiational frost occurs when leaf temperatures actually reach lower temperatures than nearby recorded air temperatures.

For the first time during the 2021 moth trapping season, more total true armyworm moths were reported than black cutworm moths. During Week 8 of the Iowa Moth Trapping Network, our cooperators reported 109 total black cutworm (BCW) and 128 true armyworm (TAW) moths.
Week 8 report...
While the rain may have limited fieldwork across the state this past week, it was much welcomed in many areas that have been on the drier side. Most of the corn and soybeans that have been planted are now emerged. Two of the more common issues seen in fields this past week included alfalfa...
Sandy to clay soils have different hydrological properties such as wilting point, field capacity, and saturation level (Fig 1a). Wilting point means no water is available to plants, field capacity means near optimum moisture for plant growth, and saturation means the soil pores are full of water...
The Forecast and Assessment of Cropping sysTemS (FACTS) webpage is evolving. When it was launched in 2015, FACTS provided forecasts soil moisture, nitrogen, phenology, and crop yields at two Iowa locations. In 2016, it was expanded to six Iowa...
Western and northern corn rootworms are serious corn pests in Iowa and the Corn Belt, primarily due to their feeding habits but also because they can overcome nearly all management tactics available to farmers. The larvae tunnel into and consume corn roots, thereby reducing nutrient and water...
Reported captures for both species in the trapping network were down from previous weeks. During Week 7 of the Iowa Moth Trapping Network, our cooperators reported 60 total black cutworm (BCW) and 22 true armyworm (TAW) moths.

As planting wraps up and crops begin to emerge across the state, data collected during planting can help you diagnose many issues in your field and determine if they were related to machine performance or agronomic factors. In this video, Program Specialist Levi Powell shows how to use spatially...
The 2021 cropping year will be remembered for a long time as an unusual year in many respects. Corn and soybean growth are off like a turtle race in many locations this season. So, we may be driving around, doing some road scouting, and asking ourselves why this is taking so long. After all, the...
Black cutworm remains the dominant moth species captured by cooperators in our trapping network. During Week 6 of the Iowa Moth Trapping Network, our cooperators reported 73 total black cutworm (BCW) and 34 true armyworm (TAW) moths.

I am always surprised to find insect abundance and diversity when scouting in alfalfa. It never disappoints. At any point in the growing season, one is likely to find 20+ species of potential pests feeding on foliage. However, finding a lot of different insects at one time doesn’t necessarily...
Planting conditions in April were pretty good for planting. In fact, there were many reports of planting in early April. Unfortunately, April was much cooler and dryer than normal. Early planted corn and soybean took longer to germinate and emerge because of these cooler conditions. Additionally...
The weather warmed up a bit during Week 5 (April 25 to May 1), and the moths were flying more than previous weeks. During Week 5 of the Iowa Moth Trapping Network, our cooperators reported 97 total black cutworm (BCW) and 33 true armyworm (TAW) moths.

Like in prior springs, we often see a trend in the weed identification questions in certain parts of the state. This spring, a small mustard species with finely-divided (I like to say frilly or lacy) leaves is the most frequent plant requiring identification by our clients. There are several...
