A Look Back at 2021 Disease Management

November 23, 2021

In 2021, as in most years, growers experienced highs and lows throughout the season. Dry weather rolled through parts of the Midwest in the summer months, which means corn crops endured high temperatures and drought while diseases swept the fields. To be best prepared for whatever 2022 has in store, growers should take a look back at what happened this season.

During the 2021 season, different regions of the U.S. experienced disease presence like tar spot, Southern corn leaf blight, rust and more. Purdue University Extension data showed that wet conditions and humidity across some states in the Midwest left corn at risk to develop foliar diseases. With these yield-robbing diseases present, regular scouting was imperative. Growers who were prepared with management plans were able to implement as soon as they identified signs of disease. Going into 2022, disease management should be built into any grower’s annual plan.

A solid disease management program includes choosing a long-lasting fungicide, to help proactively protect crops from diseases common to the region. Optimal application timing is one practice that proves beneficial to a successful yield. When applied at VT-R1, fungicide treatments can increase harvest and potential ROI. Consider a fungicide with flexible application timing and residual control so crops are protected from application to harvest.

For a fungicide that’s not afraid to work, use Trivapro® fungicide for faster canopy closure, improved water-use efficiency and stronger stalks to reduce lodging at harvest. Trivapro contains 3 complementary and non-cross-resistant modes of action, and averages +14 bu/A compared to untreated corn crops1 with a $61.10 per acre average ROI when applied in the VT through R1 growth stages.2

For 2022, growers need a fungicide that leaves corn healthier and stronger with broad-spectrum preventive and curative disease protection. Use a long-lasting fungicide to protect against yield-robbing diseases and boost ROI potential.
