Capitalize on Corn Seed Treatments In-Season
Your corn seed is in the ground and taking root. Hopefully, that seed came with a quality seed treatment already applied. Now it’s time to pay attention to the in-season value a seed treatment can bring and leverage that to begin informing your seed decisions for next year.
Benefits of a zinc seed treatment
We know that early-season zinc is critical for corn plants to promote growth and root development, which in turn, helps protect stand quality. If you’re losing stands or not seeing strong early growth, you’re probably less likely to make in-season investments in your corn crop because you don’t know where your yield is going to be. But if you’re able to get roots and stands off to a strong start, then you’re more likely to capitalize on in-season opportunities.
Since 2019, select CROPLAN® elite hybrids have come treated with Fortivent® Zn seed treatment, which supplies seed with zinc to promote seed germination and early-season plant health. Results from 41 Answer Plot® trial locations during the 2018 growing season showed an additional 4.7 bushels per acre delivered by corn treated with Fortivent Zn seed treatment vs. untreated corn seed.
Season-long zinc management
Zinc takes season-long management and is important for many functions within the plant, including enzyme creation, photosynthesis and development of auxin hormones, which signal germination. However, zinc is immobile in both the soil and the plant, so you need to supply adequate amounts throughout the season. There are three critical times to apply zinc:
On the seed as a seed treatment and with your starter fertilizer via a product like Ultra-Che® Zinc 9%
In the fall to supply late-season zinc needs with a dry product like Zinc 10% LS
New triple-threat seed treatment available
A new seed treatment that builds on the foundation of Fortivent Zn will be available for planting in time for the 2021 growing season. Fortivent Plus provides early-season insect control and plant vigor. It also delivers control of the fungi Pythium, which has become especially problematic during the last few planting seasons because of wet conditions in many areas. Fortivent Plus combines Fortivent Zn with:
Poncho® Votivo® seed treatment, which protects seeds and seedlings from early-season insects and a variety of plant-pathogenic nematodes that attack roots; and
Intego® Solo fungicide, which provides enhanced Pythium control.
Fortivent Plus will be available on CROPLAN Signature corn hybrids beginning later this year and in time for 2021 planting. Talk with your agronomist or trusted advisor about ways to optimize your current seed treatment and about making Fortivent Plus part of your 2021 farm plan as you evaluate how your 2020 corn crop is shaping up.
