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.
Subscribe to RSS FeedAs we enter the harvest season, we know we need to be looking forward to the next growing season at the same time. Having plans in place for your 2022 fertilization program before harvest starts is a good idea. Making these plans is tougher this year due to variable yields across the state due...
Choosing the best crop variety to maximize yield and profitability while still staying within budget is vital to any farm, whether its 100 acres or 100,000. It is also a driving objective for plant breeders that develop these varieties for farmers.
Plant phenotyping is an important part...
Historically, corn silage harvest starts within the next two weeks. However, harvest has started early in some droughty areas with light soils. Corn is a high yielding, high energy, low protein forage that is commonly used for growing and finishing beef cattle, in cow-calf production systems,...
My lab has been driving all over western Iowa looking for soybean gall midge. They stop by 3-6 fields in each county and scout for larvae along field edges. This is part of a larger effort funded by the North Central Soybean Research Program to better understand the current distribution of this...
I have seen yellow patches in Iowa soybean fields this past week. Plants within these patches have foliar symptoms that appear to be caused by sudden death syndrome (Figure 1; SDS). When...
With parts of northern Iowa now being in a D3 or extreme drought and other areas on the drought monitor expanding, the drier conditions are a concern with what impact they are having on the crops as well as forage...
A new Aerial Application Manual (CS 26) is now available for individuals planning to take the aerial applicator exam to become certified or renew their certification. This manual will assist aerial applicators and aerial applicator consultants in preparing to take the commercial pesticide...

The hot and dry conditions this past week resulted in crops showing more signs of stress, especially in the drier parts of the state. Drought stress, spider mites, corn rootworms, and questions regarding fungicide applications were the big questions or issues observed by ISU Extension field...
In October 2020, EPA approved five-year registrations (until 2025) for dicamba products including XtendiMax (Bayer), Engenia (BASF) and Tavium (Syngenta) for over-the-top use in Xtend and XtendFlex soybeans. These new dicamba product registrations included national cutoff dates (June 30 in most...
