Subscribe to RSS FeedThe 2021 cropping year will be remembered for a long time as an unusual year in many respects. Corn and soybean growth are off like a turtle race in many locations this season. So, we may be driving around, doing some road scouting, and asking ourselves why this is taking so long. After all, the...
Black cutworm remains the dominant moth species captured by cooperators in our trapping network. During Week 6 of the Iowa Moth Trapping Network, our cooperators reported 73 total black cutworm (BCW) and 34 true armyworm (TAW) moths.
Week 6 report:
The TAW moths...
This past week brought some much needed and welcomed rain across the state. Planting is getting on the downhill slide with corn planting about 86% complete and soybean planting about 67% complete across the state according to the...
The May 10 USDA-NASS Iowa Crop Progress Report showed 86% of the Iowa corn crop is planted and 22% is emerged; soybeans are 67% planted and 6% emerged....
I am always surprised to find insect abundance and diversity when scouting in alfalfa. It never disappoints. At any point in the growing season, one is likely to find 20+ species of potential pests feeding on foliage. However, finding a lot of different insects at one time doesn’t necessarily...
Planting conditions in April were pretty good for planting. In fact, there were many reports of planting in early April. Unfortunately, April was much cooler and dryer than normal. Early planted corn and soybean took longer to germinate and emerge because of these cooler conditions. Additionally...
The weather warmed up a bit during Week 5 (April 25 to May 1), and the moths were flying more than previous weeks. During Week 5 of the Iowa Moth Trapping Network, our cooperators reported 97 total black cutworm (BCW) and 33 true armyworm (TAW) moths.
Week 5 report:...
A lot of planting progress was made for both corn and soybeans over the last week. According to the May 3 USDA-NASS Crop Progress Report, approximately...
Cooler conditions continued into week 4, resulting in relatively few moths being caught across the state. During week 4 of the Iowa Moth Trapping Network (April 18 to April 24), our cooperators reported 56 total black cutworm (BCW) and 15 true armyworm (TAW) moths.
You may be wondering...
Soybean research and Extension specialists from land-grant universities across the country welcome you to join a monthly informal discussion on production topics that have timely relevance. By joining the Notes from the Field webinar series, you will get highlights and current issues from across...
Just last week, Ashley Dean predicted overwintering mortality of bean leaf beetle in Iowa. It looked pretty grim for this soybean pest, with over 77% mortality predicted for central...
Like in prior springs, we often see a trend in the weed identification questions in certain parts of the state. This spring, a small mustard species with finely-divided (I like to say frilly or lacy) leaves is the most frequent plant requiring identification by our clients. There are several...
It’s been an unusual spring with the cooler and drier conditions. While many would welcome a rain, the warmer conditions mean planting has gotten underway. Iowa State University Extension and Outreach field agronomists share reports on what they are seeing and hearing in their respected regions...
While the warm weather has finally arrived for planting season, dry soil is becoming an increasing concern in parts of the state. In addition to concerns about subsoil moisture, some fields have had significant surface drying, particularly in areas with more tillage this spring. Dry soil...
During week 3 of the Iowa Moth Trapping Network (April 11 to April 17), our cooperators reported 62 total black cutworm (BCW) and 9 true armyworm (TAW) moths. Cooler conditions recently may have slowed down moth migration into the state, but black cutworm remains the dominant species caught in...
The optimum rate of Nitrogen fertilizer application on corn varies from year to year and from field to field. Here we provide simulation data to aid decision making.
We simulated 25,000 fields across the U.S. Corn Belt from 1984 to 2021 using the Agricultural Production Systems sIMulator...
The concern for not having enough water during the 2021 growing season is increasing. Observations from Iowa fields (i.e., deep soil samples and tile drainage experiments), and analytical frameworks (i.e., Drought monitor) indicate below normal moisture in parts of Iowa. Here, we benchmark the...

It’s hard not to be itching to get in the field and start planting, especially since we are past the April 11th crop insurance date for planting. However, the optimum planting date is dictated by soil conditions (moisture and temperature), the weather forecast, and the calendar date...
With cool weather conditions potentially causing delays in cover crop termination, what options are available? Cereal rye ahead of soybean is not nearly as problematic. While planting green may not be advised for beginning cover crop users, more experienced cover crop users have...
Recent research showing the benefits of sulfur application to corn in Iowa have many folks asking questions about ammonium thiosulfate or ATS. ATS and ammonium sulfate (AMS) contain both nitrogen and sulfur, however in different amounts. AMS also differs from ATS in that all the sulfur in AMS is...
While it seems like most alfalfa fields are greening up quite nicely this spring, there have been a few reports of winter injury in alfalfa stands, especially if stands or parts of stands may have been covered by sheets of ice during the winter.
Take some time now to evaluate stands for...
Even though the weather has been variable this past week, one thing is certain: black cutworm is moving through Iowa. During week 2 of the Iowa Moth Trapping Network (April 4 to April 10), our cooperators reported 122 total black cutworm (BCW) and 21 true armyworm (TAW) moths. Windy conditions...
