Extension specialists in Iowa and Minnesota are again collaborating to provide a series of short webinars for farmers, ag professionals, Extension personnel and other interested parties from July 14 to July 23. The theme is “Essential Row Crop Management" for summer 2020, with a focus on key...
We’ve seen more herbicide injury to soybean than I recall in past summers, resulting in questions about determining the source and reasons for the damage. This ICM Blog will share some tips on identifying herbicide injury we’ve seen this summer in soybean fields.
Crop injury may be caused...
One important benefit of cover crops to our production system is providing an alternative selection pressure on weed populations. Cereal rye has the best potential to suppress weeds because it accumulates more biomass than other cover crop species. Weed suppression is closely related to the...
Numerous herbicides registered for postemergence use on Xtend soybean have excellent activity on important weeds of Iowa’s soybean fields. Unfortunately, herbicide resistance in waterhemp is widespread to the herbicide groups active on this weed: Group 2 (ALS inhibitors), 9 (glyphosate) and 14 (...
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...
Late last week, Dr. Justin Glisan, State Climatologist of Iowa for the Iowa Department of Agriculture and Land Stewardship, wrote some really interesting comments about the National Weather Service Climate Prediction Center monthly outlooks. We’ve...
Extension specialists in Iowa and Minnesota are collaborating to provide a series of short, daily webinars for farmers, ag professionals, Extension personnel and other interested parties from April 6 to April 10. The theme is “Essential Row Crop Management" for spring 2020, with a focus on key...
Now is the time to be thinking about improving pasture stands by either the frost seeding method in February and early March or interseeding later in the spring months. Below are guidelines and considerations when it comes to frost seeding or interseeding.
Frost seeding...
This winter we will be hosting several soil fertility workshops around the state to help farmers better understand how to interpret soil test results and make soil fertility recommendations.
Join us for one of these workshops to:
- Learn how soil tests are done and what they...
Did insects bug you and your crops this year? As the 2019 growing season winds down, ISU Extension field agronomists are seeking information from producers and retailers across the state regarding what the most problematic insect pests were this growing season.
Give us...
Temperatures fell into the low 30’s and upper 20’s in most of Iowa over the weekend of October 11-13. Because of the very late planting season, some crops were immature enough to be injured by the freezing temperatures. This ICM Blog will address frost damage concerns to soybeans.

Proper planning and preparation are needed to successfully improve pastures with either late winter frost seeding or no-till renovation with interseeding next spring. This ICM Blog post will discuss what you should be doing now to prepare for pasture renovations in 2020.
Fall is a great time to take soil samples. Soil testing is the only way to determine soil nutrient levels, and the results of these tests can help make critical management decisions for the next growing season. This article will discuss when to soil sample, different soil sampling methods, how...
The spread of multiple-resistant weeds threatens Iowa’s production system. In order to slow the expansion of resistance, greater diversity in weed management is necessary. An October 21 workshop will discuss one potential alternative weed management tool that is used in other parts of the world...
Harvest season will soon be here, and that will mean more equipment and slow-moving vehicles both on the farm and the road. This flurry of activity can result in an increased chance for farm and equipment-related accidents.
This week (September 15 – 21) is National Farm Safety and Health...
The 2019 Iowa State University Extension and Outreach Iowa State Fair Weed Identification Contest was held on August 9 outside the John Deere Agriculture Building. Contestants need to identify live samples of weeds of agricultural, horticultural, and natural habitats in Iowa. Youth are tasked...

Last week the USDA’s Risk Management Agency (RMA) changed the rules for when farmers who planted cover crops on prevented plant acres will be permitted to hay, graze, or chop those fields....
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...
Join the ISU Weed Science Program at the 2019 Herbicide Research and Demonstration Program Field Day on Thursday, June 27!
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.
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.
Soil temp. Ideally we want soil temps at the 4” depth to be 50oF or warmer prior to planting corn. While we did...
