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.
Resistance is showing up in weeds, insects and disease pathogens in Iowa and has the potential to impact yields, increase the cost of production, and limit farmers’ future
pest management options.
Examples of Resistant Weeds
Common cocklebur, common lambsquarters, common sunflower, giant foxtail, giant ragweed, horseweed, Kochia, Pennsylvania smartweed, waterhemp, and recently, Palmer amaranth.
Examples of Resistant Insects
Western corn rootworm, also soybean aphid populations near, but not yet inside, Iowa.
Examples of Resistant Diseases
Soybean cyst nematode and frogeye leaf spot.
Pilot projects will be selected from these pest options and will be used to inform management option strategies as well as collaborative efforts within communities to resolve resistant pest issues.
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.
The Iowa State University Integrated Pest Management (IPM) Program is pleased to present the eighth annual Crop Scouting Competition for Iowa Youth. High school students (those completing grades 9-12) 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.
High school students from across Iowa are invited to compete and showcase their scouting abilities in corn and soybean on August 5 at the Iowa State University Extension Farm. The competition will be a one day event with both indoor and outdoor components. The theme for this years competition is Crop Scouting Innovations. Monetary prizes will be awarded to winners.

This regional field day features key researchers and specialists participating in the North Central Soybean Research Program discussing ongoing research and recommendations for managing soybean aphid. There is no fee to attend but advance registration is requested to assist with facility and catering arrangements. CCA credits may be available. Click HERE for more information.
The Integrated Crop Management Conference offers over 30 different seminars and workshops focusing on the latest in crop production technology. Experts from Iowa and surrounding states will provide research updates and results in soil fertility, soil and water management, crop production and pest management. Attendees can choose from up to 5 topics each hour. This format allows you to customize your conference experience to meet your interests and CCA credit needs. Click HERE for more information.
The two most important pests that reduce soybean yield (nematodes and aphids) are evolving, becoming resistant to commonly used pest management tools. This workshop will provide research-based, sustainable pest management recommendations for the control of soybean cyst nematode and soybean aphid. Information provided will include updates on the status of resistant pest populations in Iowa and hands-on demonstrations of sampling and managing both pests.
