More large flights of moths were reported across Iowa last week. In fact, the statewide weekly totals for both true armyworm (TAW) and black cutworm (BCW) far exceeded those of previous weeks. Across the state, our cooperators reported a total of 243 TAW moths and 188 BCW moths between May 17...
Last week brought little sunshine, cooler temperatures, and soggy conditions across much of the state. Yellow-looking corn, slow growing crops and forages, and uneven or poor stand establishment were some of the common concerns ISU Extension field agronomists have been hearing and seeing. Read...
While all applicators should carefully read their pesticide labels, newer products like the dicamba products labeled for use over-the-top use in soybean have many more application restrictions and recordkeeping requirements than others. This blog will describe the new language in the ‘...
Thanks to ISUEO Field Agronomist Meaghan Anderson and Extension Entomologist Ashley Dean, I had a great field scouting adventure in central Iowa. First visiting the field for poor germination and other issues, Meaghan was digging in the soil in search of more information and found grubs! So of...
Last week, the Iowa State University Extension and Outreach Crops Team held its Field Scouting Basics Workshop for those who will be scouting fields this growing season. For those that might have missed this day-long virtual seminar, we've uploaded the entire virtual workshop to the Iowa...
I try to stay focused on important weed management issues, but people1 send me ads they feel need to be called out for breaking the principles of integrated weed management. Today's entry into the Herbicide Ad Hall of Shame is a promotion for Tough herbicide. I don't...
By this time in the spring, moth activity typically quiets down a bit. Not this year – we were still seeing large flights of moths last week! True armyworm (TAW) activity picked up again with a total of 84 TAW moths reported across the state. Black cutworm (BCW) captures decreased compared to...
Western and northern corn rootworms are serious corn pests in Iowa and the Corn Belt, reportedly responsible for over 1 billion dollars in yield loss and control costs annually in the United States. The larvae tunnel into and consume corn roots, which can reduce nutrient and water uptake (Figure...
With the weather Iowa has recently experienced and the time of year it is, we all can expect to see purple and yellow corn and even some tattered leaves: the ugly ducklings of your field. Don’t fret just yet, cooler temperatures and wet conditions are all contributing factors to the mosaic...
Iowa’s most significant soybean insect pest, soybean aphid, has host-alternating biology. This species has multiple, overlapping generations on soybean in the summer. Fall migration to buckthorn is based on senescing soybean, and decreasing temperatures and photoperiod. For the majority of the...
Some much-welcomed rain fell across the state this past week. Prior to the rain, farmers continued to make progress on getting the crop in the ground. According to the...
Planting is nearly wrapped up for corn, with soybean soon to follow. What a difference a year makes considering the last two years have seen planting delayed. That means corn and soybean emergence should be good, right? Wrong! The cost of seed makes it essential to get the highest, most uniform...
As crops start to emerge, now is a good time to get out and do early-season scouting to see how things went with planting and to also check for any early season crop disease and insect issues.
Check out our most recent Vlog from the Field Extension Education Lab (FEEL), where we discuss soil temperature, hypocotyls, radicles and cotyledons.
Guest starring in this episode is Meaghan Anderson, field agronomist in central Iowa and an extension field specialist at Iowa State....
As we on the Iowa State Extension Crops Team have been adjusting our programming and schedules to ensure we're still able to provide quality resources throughout COVID-19, we'd like to introduce you to one new resource: The Field Extension Education Laboratory (FEEL) Vlog series.

Even with some cooler temperatures last week, moths were still being reported around the state. True armyworm (TAW) activity was lower during Week 6 than in previous weeks with a total of 40 TAW moths reported across the state. However, black cutworm (BCW) captures increased dramatically last...
Years like this, when corn-planting progress is ahead of normal and we get really optimistic about it, frost raises its ugly head. In the NW corner of Iowa, about a third of the years will include a frost in May. About ten percent of the time it is after May 10. Watching the recovery of emerged...
What a difference the year makes! According to the May 11th USDA Crop Progress Report, 91% of the expected corn crop and 71% of the expected...
Although most crop fields have not reached the stage for regularly planned POST herbicide applications, there likely are situations where people would like to get weeds controlled prior to the rain forecast later this week. The question is what impact will this weekend’s frost have on herbicide...
The Forecasting and Assessment of Cropping Systems (FACTS) from Iowa State Extension and Outreach results as of May 5 extrapolate that Iowa soils a bit drier than neighboring Illinois or Indiana, but shouldn’t be an issue moving forward:
...Moth activity continues in Iowa. During Week 5, April 27 had the most true armyworm (TAW) moths reported across the state. Black cutworm (BCW) flights were a bit spread out throughout the week. In total, 78 BCW moths were reported across the state, which is the highest weekly total of the year...
Thin Lizzy predicted it in 1976. Actually, the boys and girls are back in town. Over the weekend, the first painted lady butterflies were spotted in Iowa. Why care about this beautiful butterfly? It seems like a distant memory, but remember the thistle caterpillar bonanza on soybean last summer...
Friday and Saturday night will have cold temperatures reach into northern Iowa and maybe even southern Iowa. Below is a National Weather Service low temperature prediction (https://digital.weather.gov) for Saturday, May 9. Notice that north of Interstate...
Last week provided another big window for planting and other field activities across the state. According to the May 4th USDA Crop Progress Report...
