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...

We have always told extension clients and students that the best tool for identifying an unknown weed is a good book, other than finding somebody who already knows what the weed is.  We never thought much of the early weed ID apps that were developed for mobile devices.  In AGRON 217 (Weed...

As everything greens up, we often receive photos of mystery plants for identification.  Typically, I get a wide range of species via email or text message.  This spring, more than any I can recall in recent history, I’ve received many photos of the same species:  purslane speedwell (Veronica...

The calendar may now say we are in the month of May, but it certainly doesn’t feel that way with the weather and with planting progress across Iowa.

One benefit of planting cover crops is their contribution to weed management.  While several factors contribute to the inhibition of weeds by cover crops, the physical barrier of cover crop residue on the soil surface is most important.  Research has shown a strong relationship between the...

This cold and snowy weather hopefully has everyone dreaming of warmer days this spring.  The 2019 growing season will be here before we know it, but now is a great time to plan for the year.  While many farmers have already purchased pesticides for the growing season, it’s important to read the...

Cool conditions during planting season increase the potential for herbicide injury to seedlings due to slow emergence and reduced ability of the crop to metabolize herbicides. While herbicides may be responsible for emergence issues, most problems that have been brought to our attention seem to...

Seeding Cover Crops in Dry Conditions

We are quickly approaching the time of year when we aerially seed cover crops into standing corn and soybeans.  Earlier seeding allows for more growth and consequently more biomass to protect soils from erosion. It also allows the opportunity to...
