Steering Through the Programs

By Jeff Schmiesing, Agronomy Department Manager

I’m going thru Dicamba changes for 2023. The spray date to quit spraying your dicamba beans in Iowa, Illinois and Indiana is June 12th. For South Dakota, the cutoff date is June 20th. If the Enlist beans blister again this summer, I’m sure we will see some more changes for 2024. If it is bad again, we may lose the post market spraying of Dicamba, and go to a pre-emergence label only.

Being they moved the spray dates up, Bayer and Croplan decided to have a rebate of $3.00 per bag for the dicamba beans you have bought for the 2023 season. The rebate will come out in September.

Also, to get the best price on your chemical purchase, try to buy all from one company to max out your rebates; they really add up fast. BASF and Bayer both have a good rebate program. With Corteva, to get the best program, you must run your chemistry through their TruChoice program. By doing this you can get an extra 15% discount.

Any questions on any of these programs, please get ahold of your agronomist. They can help steer you through these programs. Other than that, I know we need the moisture, but I’m getting tired of blowing snow this winter.




Tar Spot

By Clay Hespe, Agronomist, Dimock

Tar Spot is a fairly new disease that was first found in Indiana around 2015. This past year it has been found in a few fields in the southeastern part of the state, so it has moved fast. Different hybrids do respond different to this disease, but a fungicide application is recommended anyway. From research done so far when the disease sets in, a 30-to-60-bushel yield loss can be expected. The newer fungicides like Delaro, Veltyma and Trivapro work the best. These products will be tight supply this season. I would recommend at least trying some split field applications this year to start looking at some of these products and getting some yield data on your own farm. It may come a time in the near future where a fungicide application is part of production just a pre or a post pass. There should be a good supply of the older fungicides in the market, but these do not have some of the plant health benefits as the newer fungicides and not as much yield bump. If you are interested in the newer products, I would get those products booked.




Game Plan

By Adam Christ, Location Manager, Irene

What a busy winter it has been so far for all of us with getting prepared for this spring, whether it has been going through machines, trucks, trailers, planters, anything we can do to be ready to hit it hard this spring.

If you haven’t talked with your agronomist yet about spring planting/application now is the time to do so as spring will be here soon (hard to imagine with the snow on the ground still). Some fertilizer prices have softened a little compared to this fall, but we see some of the similar issues as last year with chemical availability that could be present again this year. Some fungicides along with some herbicides are going to be hard to get. It is also a good idea to get with your agronomist and get a game plan for insecticides to put on your crop.

I’m sure most of you are just as eager as we are to get back into the fields. Have a great season and please be safe.
