Corn Rootworm Demonstrations in Iowa this Summer
Blog Post
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.

Stalk Borers are on the Move Across Iowa
ICM News
Stalk borer is an occasional pest of corn, but it can be persistent in some fields, especially those fields near fence rows, terraces, and waterways that serve as overwintering sites. Tracking degree days is a useful tool to estimate when common stalk borer larvae begin moving into cornfields from their overwintering hosts. Foliar insecticide applications are only effective when larvae are migrating and exposed to the insecticide. Start scouting corn for larvae when 1,300-1,400 degree days (base 41°F) have accumulated.

Palmer amaranth update
Blog Post
Meaghan and Bob’s blog posts on weeds, and seeing a floater spraying yellow herbicide in 30 mph winds on Monday, reminded me to do an update on our newest problem child in the weeds world, Palmer amaranth. While we hoped that the few infestations scattered across Iowa could be contained, unfortunately a few weeks ago I found out that—in Harrison County anyway—Palmer has increased its range and seed bank.
