Agronomy Articles




By Damien Fuerst, Agronomist, Scotland

After a long weekend celebrating the 4th of July, it’s time to get back into the swing of things. The second cutting of alfalfa is under way, so talk to your local agronomist to scout for cutworms and weevils. Discuss with your agronomist insecticide options and possibly foliar feed options as well to help the third cutting. With the extra moisture this year discuss fertilizer options and fungicide options for corn as well. Hope you all had a good 4th and enjoy this warm weather that we will be having. Don’t forget bug spray!




Stress in the Field

By Clay Hespe, Agronomist, Tyndall

What a difference a year makes. I believe it was around this time last year that we got our first moisture event of over an inch. As we are getting a couple weeks out from the flooding, more fields are showing more stress and nutrient deficiencies. The big one is nitrogen loss from either denitrification from extended standing water or leaching. Potassium is also starting to show up in some areas. The potassium deficiency is due to the wet soils from poor root to soil contact and the vegetation growth is out pacing root development to feed the plant. We probably have a week or two to get side dress rigs into some fields. The best option may be 1-3 gallons of Coron with a quart of K-leaf that can be applied by ground or air. Every field will be different so talk with your local agronomist for your best option to help your corn crop through this stressful time. We need mother nature to give us 2-3 weeks of good growing conditions.




Your Operation

By Greg Bartmann, Agronomist, Marion

Spraying soybeans and top-dressing corn seem to be on the top of everyone’s list now that the major weather event from last week has passed. Just a reminder that the dicamba date for South Dakota has passed so the best weed control option for Xtendflex beans is going to be any tank mix with Liberty for water hemp, kochia, and any other hard to kill weeds. There are a few things to keep in mind when spraying Liberty that may not apply to other tank mixes that we are accustomed to spraying. AMS is critical for efficacy on all Liberty acres; do not short yourself when using either a dry or a liquid AMS. Temperature and humidity can also play a large role in how effective your liberty application is going to be. The more heat and humidity we have at the time of application the better; this is counterintuitive to what we are used to with other products in the past. The final thing to remember is to keep your water volume up. 20 gallons of water is required for good coverage as Liberty is a contact herbicide. If you are having to spray some of these fields a little sooner than you would like to based on bean size, we would also recommend adding a residual herbicide to buy us more time to get to canopy. There are plenty of good options out there including Warrant, Outlook, and Dual to name a few. As always talk with your Central Farmers representative and work out the best plan for your operation.
