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. 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.

Harvest is underway! Long days and short nights in the combine, tractor and truck give farmers time to reflect. Key things to remember from 2016 are the wet spring, dry June, wet and late summer, and early fall. With commodity prices lower than past years farmers need to begin developing budgets...

Palmer amaranth has been identified in newly-seeded conservation plantings in more than 30 Iowa counties, and we would not be surprised if the actual number is double that. The number of Palmer amaranth plants per acre has typically been low enough (<250 plants per acre) to make physical...

Seems like I have written an article on stalk rot about every year for the last five or six seasons. Luckily, for the most part, the last few years it was a “heads up” about a relatively small amount of fields that were having lodging issues. However, this year it sure seems like stalk integrity...

From a non-farm citizen perspective, safety on the roads is imperative. We have to be aware that during harvest and fall field work season, there will be a lot of large and slow moving equipment on the roads. There will also be a lot of grain trucks on the roads, and it is a tough job to drive...

Safety is always a priority for farmers at harvest, but this year may push us harder than most. If our current wet weather pattern continues into the fall, it could be a muddy, difficult 2016 harvest season.

Corn is nearing the end of its maturity here in northeast Iowa, where most of it is in between R5.75 (3/4 milk line) and R6 (physiological maturity), with the late planted fields at or past R5.5 (1/2 milk line). With all of the moisture that we’ve seen here in this area of the state, we have...

During July and August, warm nights may accelerate maturity of corn to the detriment of yield. In most areas of Iowa, 2015 and 2016 were much alike for corn. In this case, nighttime temperatures may indeed be the major factor resulting in a yield improvement or diminished yield in 2016 since...
