While in westcentral Iowa yesterday setting up some small plot experiments, I got distracted by a long stretch of grass alongside a cornfield. I noticed some “deadheads” among the green plants and decided to dig a little deeper.

Farmers and farm businesses are invitied to join us on July 7 at Southeast Research and Demonstration Farm near Crawfordsville for our Agronomy Workshop and Certified Crop Advisor Training in the morning and our Summer Field Day in the afternoon. These events are being hosted by the research...
While parts of western Iowa seem to miss the rain or get small amounts of rain, other parts of the state received over 3 inches of rain this past week and experienced flooding. Unfortunately, some areas, particularly southwest and south-central Iowa, received some significant hail damage as well...
The month of June has come roaring in with severe weather affecting crops in many different areas. This blog with briefly discuss some management considerations and resources associated with different types of early-season crop injury.

Last year, entomologists and field specialists with Iowa State University Extension and Outreach received many questions about effective management of corn rootworms as populations have increased in the past two years and farmers have experienced enhanced root injury during drought conditions....
Cutworms and armyworms, flooding, replant considerations, and weed management/herbicide application considerations were some of the more common questions ISU Extension Field Agronomists received over this last week. Read on for more specifies about what is happening and being seen across the...
Postemergence herbicide application season is already upon us in much of Iowa, but with the delayed crop planting in some areas, it may extend through much of the month of June. Herbicide application timing should always focus on the sizes of weeds targeted but remember that many products use...
Regional Update: May 23 – June 1, 2022
With planting wrapping up across the state, the attention is focusing to taking the first cutting of alfalfa, herbicide applications, and starting sidedressing nitrogen in corn. Read on to hear what ISU Extension Field Agronomist’...
The trapping season for true armyworm (TAW) and black cutworm (BCW) has come to an end. We appreciate our cooperators for tirelessly checking traps over the last two months and reporting their captures so we can provide the most accurate scouting information for these pests. To recap, we had 44...
Recent surveying suggests that farmers and their advisors are interested in receiving short bursts of information via text messaging. We formed the Iowa Pest Alert Network with the goal of providing short, timely insect pest updates to farmers and advisors through text messages. These updates...
This year’s Weed Science Field Day will be held on Thursday, July 14 at the Iowa State University Curtiss Farm, Ames, IA.
Although the 2022 cold and wet spring has significantly delayed corn and soybean planting in Iowa, we are still on track to demonstrate corn and soybean research plots...
Last week, moth flights into Iowa continued to decrease compared to previous weeks. In total, our cooperators captured 38 true armyworm (TAW) moths and 65 black cutworm (BCW) moths during Week 8 (May 15 to May 21).
Week 8 report:
Nearly all TAW moths were...
Weather conditions were quite favorable this past week allowing Iowa farmers 5.4 days for fieldwork across Iowa allowing for significant planting progress across nearly all of Iowa. With that said, there are still isolated pockets where soils remain too wet to allow for fieldwork. Frost...
It is the time of year when Extension Field Agronomists receive questions from farmers who have been asked if they can apply pesticides for their neighbors. There are a few things you should know before you agree to apply pesticides for your neighbors.
A private pesticide applicator in...
Last week, moth flights into Iowa were slightly lower than previous weeks. In total, our cooperators captured 55 true armyworm (TAW) moths and 102 black cutworm (BCW) moths during Week 7 (May 8 to May 14).
Week 7 report:
Moths of each species were captured almost...
When a pesticide application moves beyond the application site to a place it’s not wanted – known as pesticide drift – it can cause damage to acreages, gardens, and landscape plants. Pesticide drift can occur virtually anywhere – in rural areas, towns, and cities.
Are You Sure It’...
Farmers finally caught a break last week and were able to make a lot of planting progress across most of the state. Some areas that did not miss the rains last week had more limited progress made with getting the crop in the ground. The earlier planted crops and even some of the crops put in...
Western and northern corn rootworms are serious corn pests in Iowa and the Corn Belt. These pests readily adapt to management tactics, especially in continuous corn production. The larvae consume corn roots, reducing nutrient and water uptake and causing stalk lodging. The adults may also feed...
The planting is slow in 2022 – according to last Monday’s USDA Crop Progress Report corn planting was at 14% and soybean planting was at 7% complete. This is nearly two weeks behind normal. This week’s warm temperatures have driven up soil temperatures but wet soil conditions are still the...
Moth flights into Iowa continued to increase last week. In total, our cooperators captured 118 true armyworm (TAW) moths and 183 black cutworm (BCW) moths during Week 6 (May 1 to May 7).
Week 6 report:
Moths of each species were captured almost every day last...
While not much planting progress was made last week (again), the warmer and drier weather this week should provide more favorable conditions for fieldwork and planting. Some of the hot topics over the last week across the state included concerns about cover crop termination, seeding forages yet...
This spring's weather has resulted in an unusually slow start to the growing season, especially when compared with the past two years. In springs like these, field operations are condensed and there may be temptation to skip some of the field preparation to get acres planted in a timely manner....
Corn and soybean planting is progressing very slowly across the state. The starting soil conditions (temperature, water, nitrogen) however are very different from last year. In this blog we’ll benchmark soil conditions using simulated data from...
