If you’ve dealt with tar spot in recent years, you know just how quickly a foliar disease can knock down yield. Heavy tar spot infections have been shown to reduce corn yield by as much as 60 bushels per acre – and it’s not the only crop disease capable of hurting your bottom line.1 So, it’s important to think through disease management plans for this season’s corn and soybean crops now.

Will Tubbs, market development specialist for Corteva Agriscience, recommends weekly scouting to check the presence and progression of disease in fields. If weekly scouting isn’t practical, prioritize getting in fields when the crop canopy begins to close and during reproductive periods.

Key growth stages to focus on for scouting include:

  • Corn stages

    • V9 – V12

    • Pre/post-tassel

    • R2 – R3

  • Soybean stages

    • R1 – R5

“If we start seeing lesions on the leaves or any other disease symptoms, we need to pull the trigger on a fungicide application very quickly,” Tubbs says. “We need a fungicide that starts working immediately, and that’s what Aproach Prima offers us.”

Aproach® Prima fungicide provides broad-spectrum disease control for corn and soybeans with both a preventive and a curative mode of action. Watch this video to see how the fungicide works fast to protect corn yield.

In addition to disease control, Aproach Prima fungicide promotes better overall plant health.

“We see benefits when we make fungicide applications not only in heavy disease years, but we also see them in lower pressure disease years,” Tubbs says. “So, a proactive foliar fungicide application on corn or soybeans between the R1 and R3 growth stages can provide disease protection and result in healthier crops.”

These plant health benefits include:

  • Reduced plant stress during unfavorable weather conditions

  • Improved standability and less stalk lodging

  • Better crop quality and improved test weights for greater yield potential

    • Corteva Agriscience trials show the use of Aproach Prima fungicide increases corn yield by an average of nearly 15 bushels per acre and soybean yield by an average of 4.5 bushels per acre.
