Registration is now open for the Ag Chem Dealer Update and Crop Advantage meetings!

Certified Crop Advisers and commercial pesticide applicators (categories 1A, 1B, 1C, 10) will be interested in registering for the Ag Chemical Dealer Update in Ames on Wednesday, December 18. This full day meeting will provide an opportunity to receive 2019 continuing instruction and pest updates directly from our campus faculty. Read more and register here.

Considerations for continuous corn in 2020

Dr. Mark Licht, cropping systems agronomist, wrote a short ICM News article with 8 tips to make continuous corn work better for 2020. Read more about the tips in Considerations for Continuous Corn.

Managing SCN in 2020

Soil temperatures are quickly falling, but it may not be too late to grab some soil samples and test fields for soybean cyst nematode (SCN) that will be rotated to soybeans in 2020. Unfortunately, SCN populations are developing resistance to the most common breeding line (PI 88788). Very few SCN resistance options exist in soybean varieties. This makes it more important than ever to know what your SCN numbers are and choose soybean varieties wisely in infested fields.

Corn and soybean yield results

The 2019 Crop Performance Tests for both corn and for soybean are now available.  These trials are conducted annually by the ISU Department of Agronomy and the Iowa Crop Improvement Association. The reports are available for download through the above links at no charge.

Additionally, the first seed tests are available online for you to look over; you can view the summary results for a geographic area or individual locations for either corn or soybeans. You can even look at results from other states to see how hybrids/varieties held up to different growing conditions.


We need your help - What ate your bushels this year?

Did you see a swarm of thistle caterpillars this year? Do you think corn earworms or corn rootworms ate away some yield? ISU Extension Field Agronomists are seeking your input on what problematic insect pests you experienced this year via our #WhatAteMyBushels campaign.  

Please take a moment to complete the
short survey for us.
