Field Crop Insects is a publication that is a cooperative effort between the Iowa Soybean Association and the College of Agriculture and Life Sciences and Iowa State University Extension and Outreach. The publication contains descriptions and images of many pest insects as well as information on insect life cycle, damage, scouting and management options. Correct recognition and identification of insect pests is an important first step to making a proper management decision regarding any insect species found in soybean and corn.
What is the Iowa Pest Resistance Management Program?
The Iowa Pest Resistance Management Program (IPRMP) is an Iowa-specific effort to address pests--including weeds, insects and diseases--that can adapt and become resistant to chemical, genetic, and agronomic control practices. The IPRMP outlines approaches for effective, integrated management solutions that will sustainably control pests. By fostering methods to detect resistance, resistance can be delayed or even prevented, limiting the spread of pest resistance.
Upon reviewing the data collected in the study, researchers concluded that corn growers struggle with “balancing the conflicting roles of environmental stewardship and successful businessperson. In reality, short-term profit-making trumps the environmental stewardship role.”
Focus weeds for Harrison County Pest Resistance Project
The Harrison County Pest Resistance Project initially began in 2017 as a result of the introduction of Palmer amaranth in the county four years prior. As most farmers in the area are grappling with herbicide resistant weeds but do not have Palmer in their fields yet, the project was expanded to include waterhemp, marestail, and giant ragweed. Read below to learn more about these weeds and why they were included in this project.
The Harrison County landscape includes both hills and valleys. Farming techniques differ depending on the topography of the farm because what works in the valleys does not work in the hills and vice versa. Tillage is not used in the Loess Hills but it is in the bottoms.As seen in 2019, flooding on the Missouri River bottoms is a significant challenge that affects management. Deposition of sand affects how locals farm, and weed seeds are spread during flooding as well. The high water table affects other aspects of management.

The Iowa State University Integrated Pest Management (IPM) Program is pleased to present the ninth annual Crop Scouting Competition for Iowa Youth. Middle school and high school students (those completing grades 7-12) from Iowa are invited to compete and showcase crop scouting abilities in corn and soybean. The competition will be a one day event focusing on outdoor learning.
