Agronomy in the Field is a workshop series for women that provides learning opportunities over forage and crop production. Focus is placed on developing agronomic and decision-making skills that can be utilized on one’s own personal or family...
This is part 2 of a three-part series of reminders for private pesticide applicators. Part 1 discussed remaining continuing education course opportunities...
Iowa private pesticide applicators are required to be certified to apply pesticides if they are using restricted-use pesticides. Initially, to get certified, applicators need to take and pass an exam. Then, to maintain their certification, applicators can either attend a 2-hour continuing...
Small grains, like oats, seeded in the spring can be another forage source for livestock producers. While using small grains, like oats, as a forage source is not something new, there is very limited data available on...
Frost seeding is the easiest and least expensive method for adding new legumes to a pasture. And now is the perfect time to be doing frost seeding.
The goal of frost seeding is to seed while the soil is frozen (usually first then in the morning) and get the seed in contact with bare soil...
One of the label requirements for the dicamba products labeled for over-the-top use in soybean (Xtendimax, Tavium, Engenia) is that applicators must complete a special dicamba training annually. If you need to complete this training, go to the ...
While the rains the end of August have helped to improve the dry conditions some across the state, the rains also brought along some strong winds and hail that caused some significant crop damage in parts of NE, EC, and SE...
Mark your calendars for our upcoming fall field days. Below is a list of the upcoming field days that will take place in early September and topics featured at each field day. All field days are free and open to the public. We hope you can join us!
Sept. 7, 2021 – Annual Forage...
The drier and warm conditions have really pushed crops along across the state. In addition to the drought concerns and issues related to the drought, other common observations made in fields across the state include more sightings of tar spot, sudden death syndrome and/or brown stem rot in...
With parts of northern Iowa now being in a D3 or extreme drought and other areas on the drought monitor expanding, the drier conditions are a concern with what impact they are having on the crops as well as forage...
Corn rootworms, spider mites, soybean gall midge, and the hot and dry conditions were common questions or issues received or observed by ISU Extension and Outreach field agronomists this past week. Read on for more specifics about what’s happening around the state.
Northwest Iowa...
The hot and dry conditions this past week resulted in crops showing more signs of stress, especially in the drier parts of the state. Drought stress, spider mites, corn rootworms, and questions regarding fungicide applications were the big questions or issues observed by ISU Extension field...
Last week, a team of us met up at the Iowa State University Southeast Research Farm (SERF) to evaluate root injury in a small trial for corn rootworm management. The trial had four treatments replicated eight times. The treatments included no management (glyphosate-tolerant only; no Bt traits or...
Corn started pollinating within the last week, and soybeans range from full flowering (R2) to beginning pod (R2). The hot topics this past week across the state included foliar fungicide decisions, corn rootworms, and herbicide injury in soybeans. Read on for more specifics on what ISU Extension...
The drier parts of the state finally received some much-needed rainfall, and unfortunately parts of southern Iowa that are pretty well saturated also received some more rain this past week. Herbicide injury in soybeans,...
Herbicide drift, fungicide decisions, and iron deficiency chlorosis were common questions or issues received and/or observed by ISU Extension and Outreach field agronomists this past week. Read on to see what's happening in different regions across the state.
North Central Iowa...
While some much-needed rain did come this past week it seems that the drier areas continue to miss out or get minimal rainfall and the wetter parts of the state keep getting wetter. The rain also brought some hail, which caused some pretty significant damage not just to crops but property as...
The hot and dry conditions last week resulted in many fields showing signs of stress. Thankfully, a much-needed rain fell across a good part of the state late last week and on Sunday evening. Unfortunately, most of NW Iowa seemed to miss out on the rain. With the much-needed rain, there was also...
While some areas received some much need precipitation later last week and over the weekend, there was some hail that came with it. Some fields have pretty minor hail damage and other fields had some pretty significant hail damage.
While some areas did receive some much-needed rainfall across the state, most areas received very little to no rainfall this past week. Consequently, it wasn’t hard to see lot of corn fields with leaves rolling this past week across the state. Lots of POST herbicide applications, sidedressing,...
This past week brought a range of field activities from replanting and POST herbicide applications to putting up hay and sidedressing nitrogen. Herbicide injury and carryover, dry conditions, yellow corn, and alfalfa weevils have been some of the more common issues ISU Extension field...
The dry conditions are causing some to see what is known as “floppy” corn (aka rootless corn). Rootless corn is easy to diagnose – simply dig up plants that are not standing erect like they should be, then gently knock off the soil to get a look at the roots. With rootless corn you will see the...
Frost damage, uneven corn, yellow looking crops, and volunteer corn becoming more prevalent were some of the more common issues observed in fields this past week. Read on for more specifics about what ISU Extension and Outreach field agronomists are hearing and seeing across the state.

For those worried about the need for additional N this spring, one method in determining if additional N is needed is by doing the Late Spring Soil Nitrate Test (LSNT). This test measures the nitrate-N concentration in the top foot of soil. The measured N is a combination of nitrate residual...
Carbon markets and weed management strategies in soybeans will be the featured topics at an upcoming Agronomy Workshop and Crop Advisor Training being offered from 8 AM to noon on June 16 at the Southeast Iowa Research and Demonstration Farm located near Crawfordsville.
