Staging crops is an underappreciated but incredibly important skill. One very important reason to know how to stage your crops is because herbicide products may have limits on what growth stages of the crop they can be applied. This ICM Blog will discuss staging corn and soybean as well as share...

The most effective way to make treatments decisions for pests with chewing mouthparts (e.g., Japanese beetle, bean leaf beetle, caterpillars, and grasshoppers) is to estimate defoliation. I’m a “lumper” and don’t try too hard to distinguish feeding by species. Replicated data over multiple...

I’ve been hearing about and seeing a variety of caterpillars in seedling crops this week. In soybean, you notice thistle caterpillars feeding and making webbed cavities from the leaves. They can be easy to find in early-vegetative soybean but rarely build up to economic populations. Read more...

Corn planting has been start and stop, and generally delayed this spring. In some situations the decision was made to plant and not apply nitrogen, or planting progressed so quickly that UAN (urea-ammonium nitrate solution) and herbicide applications couldn’t keep up with the planters, and now...

Everyone is talking about the cool, wet spring this year. It's definitely slowed down my research projects, too. Thanks to the help of the Tylka Lab, we have about half our soybean plots in the ground. I am working on soybean aphid efficacy evaluations at the NWRF near Sutherland. I am starting...
