Kernel to Kernel with Tanner

B99R54V / B99R54PCE
BREVANT • 99 day

Tanner’s Top Takeaways:

→ Exciting top end yield potential. This hybrid was 2^nd/26 hybrids across 19 different Answer Plot sites in 2025. The only hybrid beating this 99-day was a 103-day, beating it by just 3 bushels!

→ Yielding that well across that many different Answer Plots gives me confidence it can handle a lot of different soil types and environments.

→ Has a nice ear flex.

→ Emergence has been great. One of the top emerging corn hybrids in my plots the last 2 years, allowing for early planting if need be.

→ Medium statured plant that has very good stay green.

→ Has silage characteristics as well. Highly suitable rating for fiber digestibility and starch content.

B99R54 is a key product I am watching and am excited to see what it will bring in 2026. Catch you on next weeks seed spotlight! – Tanner

MINNESOTA – WEST

Belle Plaine – Le Center – Le Sueur – Morristown – Traverse

We’ve had a productive few weeks of spraying in the Le Sueur area. We started the season with hot, humid conditions and have recently transitioned to cooler, drier weather. While these conditions can slow herbicide activity and make weed control more challenging, strong results are still achievable with the right herbicide and adjuvant package.

The field pictured below is an Enlist E3 soybean field with a heavy population of waterhemp. It was treated with Enlist, Liberty Ultra, Cornerstone 5 Plus, Class Act, AMS, and StrikeLock. Application conditions were favorable, with sunny skies and temperatures around 70°F. The photos were taken three days apart and demonstrate the early activity of the treatment. Even under cooler conditions, the combination of herbicides and adjuvants provides strong uptake and performance.

As we move through the season, selecting the right tank-mix partners and adjuvants will remain an important part of maximizing herbicide performance and protecting yield potential. – Jake

MINNESOTA – EAST

Goodhue – Kenyon – Lake City – Pine Island – Wanamingo

Here are some random agronomy notes from around the Goodhue area the past week:

• The 30-day rainfall continues to be well below normal despite the recent rains. Most areas are 2 to 3 inches behind normal, with some areas approaching 4 inches.  Overall, the crop looks good and timely rains have improved conditions, but a substantial rainfall event would be welcome before tasseling begins.  Our yield potential is still very strong across our “A” and “B” zones, but if we continue to be dry expect lower yields in “C” zones compared to 2025.

• Adding Superb HC (COC) to post corn herbicide mixes substantially improved and sped up weed control of waterhemp. A good note to keep for 2027 herbicide planning.
• Wind and scattered rain have caused the first delay in spraying we have seen all season.  Waterhemp and other weeds continue to grow. With bigger weeds it is critical that you run 20 gallons of water spraying and use the correct adjuvant loads during Liberty/Enlist spraying E3 soybeans.  Weed control will suffer if you do not follow proper practices. 

• Soybean fields without a pre and no post application are very weedy.  With the lower soybean prices some growers are trying to cheat and get by with one herbicide pass or no pre pass.  In the picture below, expect at least 5 to 10 bushels of yield loss from weed competition (not an Ag Partners customer and not organic).  Pre herbicides protect yield and make you money.

MINNESOTA – SOUTH

Elgin – Lewiston – Stewartville

As we begin to wrap up corn post emerge spraying, it is still extremely important to scout your corn, not only for weed kill conformation, but for armyworms as well. Armyworms do not overwinter here; they migrate from the south. We are seeing so many because of the strong winds and storm fronts in mid-May that dumped massive numbers of moths into the area, which then laid millions of eggs. Corn planted into rye would be my top priority when it comes to scouting for these critters. Armyworm feeding typically appears as ragged leaf feeding on the margins and shredded leaves within the whorl. During the day they like to hide in the whorl or on the soil surface if it is cloudy and/or wet (as seen in the photos) . If you think you might have armyworms in your field, don’t hesitate to reach out to your local Ag Partners Agronomist. – Will

WESTERN WISCONSIN

Durand – Ellsworth – New Richmond – Osseo

Sidedress is in full swing here in Western Wisconsin and the next few weeks will fly by as we slowly begin to wrap up second pass herbicide applications and Nitrogen for 2026.

I know we have touched on variable rate Nitrogen quite a bit in our last few weeks of agronomy updates, so I wanted to drop one last reminder for growers. It may be a bit far into the season now, but it is never too late to start planning for next year. Whether you’re interested in variable rate applying nitrogen based on management zones (built by years of yield history in AYS); or you want to learn more about in-season nitrate sampling (to VR based on available N from manure) – Nitrogen placement is just as important as our total applied rates if we want to be as efficient and economical as possible in a tough year.

That said, with the end of June being so near, it’s also important to be on the lookout for any last-minute changes or problems that can still be addressed. The clock is ticking on our ability to clean up any problem weeds that are breaking through, especially in corn. Waterhemp in particular has had no problem blowing through our pre-emerge herbicides in areas that didn’t receive enough rain to activate them. Status herbicide is a great option for post emergence waterhemp control, however it cannot be applied if corn is more than 36” tall or V8 stage (which much of our corn is at or approaching). Before we know it, it will be time to start planning for fungicide, but for now I hope everyone enjoys the rest of June Dairy Month! – Kirsten
