Broad-Headed Bugs in Soybean: Should You Be Worried?

This week we received a report of insects infesting a soybean field. However, they weren’t insects that we generally think of when the term "soybean insect pests" comes up.

Two leaves of corn, one showing signs of Southern Rust, the other with Common Rust.

Southern Rust Developing Late in Corn

Southern rust was found in a few corn fields scouted last week. This rust is developing very late in the season and therefore its impact on corn yield will be minimal.

Fall Frost and September Climate Outlook for 2019

September 2019 has been pleasantly warmer than usual, and our crops need every bit of that warmth to reach maturity before our first frost arrives. Fortunately, temperatures have cooled slightly this week but just to near average for this time of year.

How Late is Too Late for the Last Alfalfa Cutting?

With a very challenging growing season and flooding across parts of South Dakota, many growers have struggled to harvest high quality forages in-between rains this summer.

Harvesting Silage on a Wet Year: Moisture is Critical

Fall is on its way in South Dakota. However, with many flooded and saturated fields, some producers are growing concerned that there will be little opportunity to harvest silage before corn dries down past desired moisture levels or frost occurs.

Fall Noxious Weed Control

Fall weed control can give the best weed control, but it also can be a poor time. If the noxious weeds were sprayed or clipped earlier this summer and there is good weed growth now, this would be a excellent time to spray these weeds and get a good kill.

Early Yellowing in a Soybean Field May Indicate Presence of the Soybean Cyst Nematode

Some portions of soybean fields may show clusters of plants yellowing while the rest of the field is still green. One of the factors that could lead to soybean plants showing early yellowing in clusters is soybean cyst nematode (SCN).

Fallow Syndrome: What is it and how do I deal with it?

Fallow syndrome received its name from the dry plains states, where fields routinely benefited from the additional moisture available after a year where the ground was fallowed. Corn sometimes had symptoms of phosphorus deficiency when grown on this previously fallowed ground, thus it received its current name, “fallow syndrome.”

Should I Be Concerned About Grasshoppers When Planting Winter Wheat?

During 2019 we have received varying reports regarding grasshopper populations. Many reports have indicated that grasshopper numbers are down. However, we have also received reports of very large grasshopper populations in some areas of South Dakota. So why such a difference?
