Insect Management: Managing Soybean Aphids

Will soybean aphids break out this year, forcing growers to spray?  Our advice – stay tuned to the Ag news in Illinois to see if aphids are breaking out. At the moment things are quiet and we have to wait and see what happens. However, take notice that aphids have been sighted in states like the Dakotas, Minnesota and Wisconsin. So there is a chance that populations will show up in Illinois, and in the northern part of the state first. Sightings in nearby states during the first half of July reveal relatively low numbers so far. The aphid has [...]

Agronomy: Evaluate New Soybean Production Practices on Your Farm

Continuing to improve soybean yields demands continued research to fine-tune production systems. That means a need to continue research at all levels − USDA, universities, industry and innovative growers. And that requires on-farm testing by local input suppliers and farmers. You can benefit from all of these programs to learn about new products, practices and ideas that may be implemented in your own soybean production system.    Soybean production practices should be adapted to your own farm, under your management, with your own resources. General production guidelines available from university research and extension programs is a good place to start. [...]

Agronomy: U of I Agronomy Day

Join us on Thursday, August 18th for Agronomy Day! Discover the latest research, technology, and industry data from University of Illinois faculty and staff in the College of ACES. The event will be hosted in a new location: 4202 South First Street in Savoy, Illinois. In addition to a new location, we’ve made many improvements for participants including: disabled parking, shorter walking distances between tours, new faculty speakers, and a tour of SoyFACE. Field tours begin at 7 a.m. with presentations from researchers covering: nutrient management, drone demonstrations, farm economics, weed management, plant diseases, and more! Don’t miss new Illinois [...]

Insect Management: Managing foliar-feeding pests of soybean

The decision to treat for foliar-feeding insects in soybean is based upon a threshold for plant defoliation, but it is important to know what insect pests are out there, since the management options can vary by pest. In addition to insects that feed on plant foliage, you may find other yield robbers such as piercing/sucking insects, i.e., soybean aphid and various stink bug species. The first step in managing any insect pest is identifying what is out there. This is most easily determined by using a sweep net to collect insects from random locations in the field. Fifteen to twenty [...]

Disease Management: To spray or not to spray fungicides, that is the question

The two most common foliar diseases in Illinois that will respond to fungicides are Frogeye leaf spot and Septoria brown spot. Cercospora leaf blight is a close runner-up. Both Frogeye leaf spot and Septoria brown spot can be considered diseases that favor wet, warm, humid weather—conditions we experience here in Illinois. Sometimes to help farmers scout, I tell them that if they are seeing Gray leaf spot in their corn, then it is time to scout their soybeans. These diseases can infect early in the soybean growth stage if conditions are favorable. The other less-common foliar diseases in soybeans such [...]

Agronomy: Harsh Conditions for Planting Double Crop Soybeans

While the early spring and long hot dry spell in June allowed wheat to mature early and harvest to occur about 5-7 days earlier than normal, field conditions at the time of harvest and afterward were quite variable for planting double crop soybeans. There were many instances of fields that were very dry and hard with little or no moisture in them, to fields that had some moisture down 2 inches and deeper. Some found moisture only in the “flat” areas of the field and nowhere else. Other issues also may have contributed to difficult planting. Most of the early [...]

Plant and Soil Health: Be a Good Neighbor: Reducing Nutrient Loss on Your Operation

It’s a long way from Illinois to the Gulf of Mexico—but out of sight cannot mean out of mind when it comes to managing nutrients on your fields. The actions you take have a huge impact on nitrogen and phosphorus levels in water hundreds of miles away. Though agriculture has made significant strides in improving nutrient utilization over the years, it must do even better in the future. Pick Up the Pace Illinois growers are doing many things right, but now it’s time to take even more care to ensure that nutrients remain on your fields to aid productivity rather [...]

Weed Management: Optimizing Liberty Performance

Weed resistance is a fact of life when growing corn and soybeans. Growers need multiple tools available and LibertyLink® soybeans and Liberty® herbicide are two of those tools. However, applying Liberty and getting good performance is not as easy as spraying on glyphosate. You need to pay more attention to weed height and application instructions and strive to get it right. That means paying attention to the details. Eric Ifft, Customer Business Advisor with Bayer CropScience, provided this list of tips when it comes to applying Liberty on LibertyLink soybeans. Timing In-crop: emergence up to bloom Late evening applications may [...]

Agronomy: What does tissue testing tell us?

This past weekend I was scrolling through Twitter and came across a feed that had been started by a well-known and respected Illinois agronomist posting an article from Academia in Arkansas on the use of tissue testing as a guide for foliar nutrition applications (it’s a very good article, by the way). This started a lively debate on the merits of foliars and the value of tissue testing at all. While I do not plan to jump into that debate and sat quietly on the sidelines, I will share my opinion for what it is worth. First, tissue testing is [...]

Plant and Soil Health: Are your soybeans thirsty and will yields suffer?

We can easily see corn showing drought symptoms, but signs of soybeans under drought stress may not be as evident. When soybeans suffer from heat and water stress, their response may vary due to their cellular structures, metabolic processes, and physiological development, which all can directly and indirectly cause soybeans to exhibit symptoms based on their response. Early season soybean stress may cause leaves to be smaller or limit vegetative growth, thus more energy and efforts may be given to root development. A more obvious sign may be leaf flipping, which is like corn rolling. Soybeans may flip leaves to [...]
