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.

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...
One benefit of planting cover crops is their contribution to weed management. While several factors contribute to the inhibition of weeds by cover crops, the physical barrier of cover crop residue on the soil surface is most important. Research has shown a strong relationship between the...
This cold and snowy weather hopefully has everyone dreaming of warmer days this spring. The 2019 growing season will be here before we know it, but now is a great time to plan for the year. While many farmers have already purchased pesticides for the growing season, it’s important to read the...
This is the final article of a four-part series originally posted in 2016 on using multiple, effective herbicide sites of action (herbicide groups) at effective rates as part of a long-term weed management system. Read ...

This is part one of a four-part series originally posted in 2016 on using multiple, effective herbicide sites of action (herbicide groups) at effective rates as part of a long-term weed management system.
With the stagnant development of new herbicides and weeds seemingly...
Another contest is in the books, and once again we provided a sufficient challenge to prevent anyone from earning a perfect score. In the Professional Division, two-time defending champion Cindy Recker was narrowly edged out by Karen Stiles, last year’s winner in the General Division. Both...
Join us for the fall field day at the Southeast Research and Demonstration Farm on September 6, 2018
Mark your calendar for the September 6 Fall Field Day at the Southeast Research and Demonstration Farm near Crawfordsville.
This year’s fall field day will feature the following topics:
- “A Season in Review” by Myron Rees, Southeast Research Farm Superintendent...
Mile-a-minute weed (Persicaria perfoliata) is an invasive species in the Polygonaceae (smartweed) family that is native to Asia. It is believed to have been introduced to the United States in the late 1800’s and early 1900’s, but the initial introductions failed to form permanent...
On June 28, Iowa State University Extension and Outreach will be hosting the annual Spring Field Day and Certified Crop Advisor (CCA) Training at the Southeast Iowa Research and Demonstration Farm near Crawfordsville.

Cool conditions during planting season increase the potential for herbicide injury to seedlings due to slow emergence and reduced ability of the crop to metabolize herbicides. While herbicides may be responsible for emergence issues, most problems that have been brought to our attention seem to...
