Get the Most Out of Your Late-planted Corn

June 19, 2019

Historical levels of rain and flooding across the Midwest and South have caused many growers to plant after the optimal planting date. If you’re one of those growers, you’re likely thinking about the potential impact the delay will have on your corn’s development and yield potential. Be sure to prepare for:

  • Increased foliar disease pressure: Pathogens that cause diseases like Northern corn leaf blight thrive in wet, humid conditions. With the wet spring we’ve experienced, prepare for disease pressure to be higher compared to 2018. Expect more damage than a typical year because late-planted, less mature corn is more vulnerable to yield loss from disease.
  • Elevated risk for stalk diseases and lodging: Planting delays push back harvest dates, raising the risk of stalk rot and yield loss due to lodging.

Preserve every bushel possible with proven technologies

If you’ve lost bushels due to foliar disease and lodging in the past, you know the importance of maximizing stalk strength and preserving valuable leaf tissue. However, do you know exactly how foliar disease impacts stalk health?

According to Michigan State University Extension, if the ear leaf cannot adequately support grain fill due to disease compromising photosynthesis, energy is diverted from the stalk to help fill out the ear. This leads to weakened stalks, more lodging and reduced harvestability. The negative impact is even greater in late-planted corn.

Applying a fungicide may not be at the top of your to-do list, but the right treatment will help preserve yield potential for late-planted corn. We recommend applying Trivapro® fungicide at V4-V8 timing, VT/R1 growth stages or both for preventive and curative control of foliar and stalk diseases that threaten yield potential.

Trivapro provides excellent control of gray leaf spot, Northern corn leaf blight, Anthracnose stalk rot and other foliar diseases that contribute to lodging and yield loss. Three robust active ingredients, including Solatenol® fungicide, make Trivapro the hardest-working, longest-lasting fungicide on the market.

A 2018 trial by the University of Wisconsin showed that corn treated with Trivapro saw an approximate 60% reduction in stalk rot over untreated corn[1].

In addition to offering broad-spectrum disease control, Trivapro delivers plant-health benefits that help preserve stalk strength and harvest efficiency at the end of the year. The comparison below demonstrates how Trivapro improves stalk strength.
