Corn Rootworm Demonstrations in Iowa this Summer

Last year, entomologists and field specialists with Iowa State University Extension and Outreach received many questions about effective management of corn rootworms as populations have increased in the past two years and farmers have experienced enhanced root injury during drought conditions. We teamed up with the ISU extension field agronomists to host corn rootworm management field days at 7 ISU Research and Demonstration Farms in 2022. Come join us this summer to learn about corn rootworm identification, sampling, management, and resistance. Each farm has planted a demonstration showcasing three hybrids (no Bt for corn rootworm, SmartStax®, and SmartStax® Pro) with and without a soil-applied insecticide.

These field days are free to attend, but please contact the field agronomist hosting each event to RSVP for food and handouts.
