In-Season Management Tips for Spring Wheat

Joel and Kyle
Hosts, WinField
On this episode of the Deal With Yield®, host Kyle Reiner and agronomist Jason Hanson discuss in-season management for spring wheat and the impact these practices can have on yield. Tune in to hear Hanson’s tips for getting plants off to a strong start with plant growth regulators, assessing nutrient needs using tissue samples and making timely herbicide and fungicide applications to optimize yield potential. Kyle and Jason also look at the differences in wheat production in the Upper Midwest versus overseas.

The Deal With Yield is a podcast series covering the issues that matter most in crop production.

Cool, Wet Weather Is Perfect for Ascend® Plant Growth Regulators

Adam Mangum
Marketing Manager, Plant Nutrition
With the recent round of cool, wet weather this spring, we at WinField want to remind you that Ascend® plant growth regulators (PGRs) can help improve yields, even when the weather doesn’t cooperate.
Three years of Answer Plot® results have shown that when planting corn into cold and wet soil, adding Ascend® PGRs in-furrow resulted in increased yields more than 65 percent of the time, with average yield boosts of more than 8 bushels per acre.

Soil Temperature* Answer Plot® Locations % Positive Response Sites Average Positive Response
< 50°F 50 67.3 8.2 bu/A
< 60°F 98 65.4 8.1 bu/A
*Two weeks before and two weeks after planting

Temperature and moisture play key roles in influencing the hormone balance that signals germination. Cool, wet conditions may restrict this growth and development. The addition of the plant growth regulators found in Ascend® PGRs may help the plant germinate even when conditions aren’t ideal. When the weeks after planting were cold and wet, corn planted with Ascend® PGRs in-furrow showed positive yield response more than 69 percent of the time.

Ascend® PGRs contain an optimal combination of three EPA-registered plant growth regulators: cytokinin, gibberellic acid and indolebutyric acid. These active ingredients promote vigorous early plant germination and emergence, a robust root system, larger leaves, and wider stems.

So even if it’s not 60 degrees and sunny when you plant, an in-furrow application of Ascend® PGRs on corn can help improve yields, rain or shine.

Spark Winter Wheat Growth Before Planting

Darrin Holder
Agronomist, WinField
You only get one shot to get your winter wheat out of the ground and achieve the stand quality you want. Rather than leave it to chance, be proactive and give your crop the extra boost it needs to reach its yield potential using a proven seed treatment/plant growth regulator combination.
Applying Warden® Cereals II seed treatment plus Ascend® plant growth regulator (PGR) adds a layer of protection, providing better germination, quicker emergence, and larger above- and below-ground growth than untreated seed.
Winter wheat has the ability to tiller, and those tillers will put on heads. Too often those heads are smaller than the ones on the main stem. Applying a quality seed treatment can help you achieve more main stems and heads at the end.
Warden® Cereals II seed treatment is the second generation of the WinField® Warden® Cereals brand. It includes a new fungicide package of three fungicides with different modes of action for broader-spectrum disease control, delivered in a formulation that’s easy to use and handle.
  • Mefenoxam, the same active ingredient in Apron XL®, protects young cereals from Pythium Damping-Off and other seedling blights and root rots caused by Pythium spp. early in the year.
  • Sedaxane, a succinate dehydrogenase inhibitor (SDHI), fungicide, is specially formulated for seed treatments and provides excellent protection against Rhizoctonia.  
  • Difenoconazole, which is a proven fungicide for control against dwarf and other bunts, along with smuts, including loose, covered and flag.
Ascend® plant growth regulator contains the optimal combination of three EPA-registered PGRs — cytokinin, gibberellic acid and indolebutyric acid — to encourage vigorous early plant germination and emergence, a robust root system, larger leaves and wider stems.

Now is the time to optimize soybean growth

Darrin Holder
Agronomist, WinField
As soybeans enter the reproductive stage, farmers have an opportunity to give their plants a boost by adding Ascend® plant growth regulator to their fungicide and late-season nutrient applications.
Soybean plants receiving a foliar application of Ascend® plant growth regulator between R1 and R3 have the potential for wider stalks and larger leaves necessary to establish a larger canopy compared to no application. The additional photosynthetic capability helps plants set larger pods with higher bean counts. Don’t miss the window to apply Ascend® plant growth regulator now to help increase yield potential at harvest.
“Particularly in higher-yielding environments, we have seen excellent response to foliar application of Ascend® plant growth regulator,” says Darrin Holder, WinField agronomist. “Take a trifoliate leaf from the 15th node of a soybean plant treated with Ascend® plant growth regulator and compare it to the same leaf of an untreated plant. You will see the treated leaf is physically larger. Bigger leaves promote photosynthesis to feed the plant and increase pod production.”
Timely application of Ascend® plant growth regulator also helps ease the potential stress of continuous flowering during the reproductive stage compared to no application.
“Our data shows that early reproductive stages are the prime time to increase biomass and optimize yield potential with a foliar application of Ascend® plant growth regulator,” says Holder.
Holder recommends applying Ascend® now to hit this critical time, when the sun is at its highest and the plant can absorb the most sunlight. “Now is the time to do it. If you wait until after the pods are set, you’ll miss the opportunity,” says Holder. “Producing a healthier soybean crop is key to mitigating plant stress and increasing yield potential.”

Spring Plant Nutrition Checklist: 4 Ways to Start Strong

Answer Plot®
Research Team
This spring could be the start of your greatest year yet. Managing plant nutrition early in the season is one way to help achieve aggressive yield goals. “A proactive approach to plant nutrition helps get crops off to a strong start and can help prevent problems later in the season,” says Adam Mangum, marketing manager, WinField. He offers the following checklist to guide spring fertility decisions.

Work with your WinField agronomist to review last year’s tissue sample results to detect any nutrient deficiencies in your area. Compare findings with fertility programs to identify gaps that could be treated early with starter fertilizers.

Review fall soil samples or gather them as soon as spring conditions allow to evaluate what nutrients are present in the field.

Once nutrient needs are determined, consider the optimum nitrogen, phosphorus and potassium (NPK) blend. Also, adding WinField micronutrients to the starter mix will help increase the quantity of nutrients available and the length of time they are available for plant uptake.

WinField Ascend® Plant Growth Regulator (PGR) gives crops an unparalleled advantage. When applied with the starter mix, Ascend® PGR promotes bigger roots, stronger stalks and faster emergence, giving plants the boost they need for a strong start and more uniform emergence.
