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 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.

While some rainfall has come to the droughty areas of the state, drought intensified to D3 (extreme) drought in parts of central and west central Iowa. Unfortunately, a large swath of the state is now facing...
Drought conditions persist in western Iowa and have expanded further into central and north central Iowa this week. Common issues reported by ISU Extension field agronomists this past week included poor grain fill and fast reproductive development in corn, increasing disease pressure in some...
In the interview, “A Farmer’s Journey with Miscanthus: Part 1,” we learned about Steve Schomberg and his involvement with growing miscanthus for the University of Iowa power plant. Steve has also been working with Koch Angus Farms, a cattle production farm near Letts, Iowa for the last four...

Over the last two weeks I have received a few calls related to identifying a “new form of waterhemp” in Southwest Iowa. In reality, we do not have a new form of waterhemp, but a condition referred to as ‘fasciation’ (Figure 1). While this can occur in many plant species, plants like cacti and...
While the drought concerns and drought impacts on row crops and forage crops seems to be the big issue especially in western Iowa, other common issues or questions reported by ISU Extension field agronomists this past week included corn rootworm activity, earworm feeding, Japanese beetles...
Growing up on his family’s farm, Steve Schomberg learned the importance of environmentalism by his father. Conservation and sustainability remained central to Steve’s life while he worked at the University of Illinois, which is where he first learned about miscanthus and its use as a biomass...
One option to consider in fields with severe storm damage with no or limited yield potential is annual forages. This option may especially be of interest to livestock producers who could utilize the forage or may be short on forage or feed as a result of the storm damage. The following...

In 2018 and 2019, research was conducted on a relay intercropping and double cropping systems to evaluate as a possible alternative to Iowa’s traditional corn-soybean or continuous corn cropping system.
There were 2 sites; one near Kalona and another near Ames, Iowa, to study these...
Each year, decisions on planting date and cultivar selection are the major deciding factors on yield potential. Under current, year-to-year variable weather patterns and future climate change these decisions have become much more important. And there is a known knowledge gap on how future...
For a couple of years, some Iowa farmers have noticed lower yields along the southern and/or western edges of their fields. The low yields along the border tend to be prevalent when soybean, hay, or pasture are growing adjacently to the field on the southern or western edge. This phenomenon...
Now is the time when decisions to apply a foliar fungicide in soybeans are being made. As you are making that decision, this is a quick reminder that fungicide resistance, particularly to the quinone outside inhibitor (QoI) fungicides (FRAC Code 11), has been found to be widespread in Iowa in...
Since July 1 high humidity and temperatures have been scorching Iowa. Okay, maybe that is a little extreme. June has led to dry conditions across much of central and southwest Iowa. Heat and dry weather are not desired weather conditions in the 2 weeks before or after pollination. This four-week...
There is no question that dicamba injury across the Iowa landscape in 2020 is the most extensive it has been since the introduction of dicamba in the 1960s. ISUEO field agronomists and commercial agronomists in several areas of the state report nearly all non-dicamba resistant soybean are...
