Over the past few decades, producers have begun to continually face herbicide resistant weed pressure throughout their cropping systems. Continuous use of the same herbicide program can quickly develop resistant weed biotypes, especially if there are no other weed management tactics being used...

Corn field edge effect has once again show up in Iowa. It is raising questions about what is causing it. In 2019 and 2020, I was able to conduct some exploratory data collection to learn more about the phenomenon.

What is it? Edge effect in corn is where the outside rows...

All it takes to start a fire is just a spark from an engine, an overheated bearing on a combine, or a hot exhaust manifold where some dirt and dry plant material have gathered. Dry plant residue, dusty conditions, low humidity levels and strong winds are a recipe for combine and field fires....

It’s hard to believe another growing season has come and is almost gone. 2022 has had its share of challenges: a wet start, drought, corn root worm, soybean gall midge, pigweed, and (my favorite) tar spot. And now, as we approach harvest, we face final challenges like ear and crown rot.

Before the rush of harvest gets here, take some time to get your grain bins ready for a new crop. The first step in minimizing grain spoilage from insects is to start with a clean bin. Grain-feeding pests can survive on residual grain, broken kernels, fines, foreign material, and molds...

I continue to receive tar spot reports from across Iowa. Given the moisture we have had the past couple of weeks and the growth stage of the crop, this is not surprising.  Tar spot development is favored by leaf moisture. As the growing season...
