DISEASE DEVELOPMENT
Disease Management
Maintaining optimum plant health, allowing the plant to finish strong, is critical for high yields and especially higher seed weight. Agronomist Jason Roth discusses how late season crop villains can negatively impact the yield of your 2024 crop and why having a fungicide program is important to preserve your potential.

Understanding the Impact of Disease on Your Acres
Disease on your acres can have a profound impact on your yield. The chart shows yield losses across 28 states. There was a loss of around 150 million bushels on corn from tar spot, northern corn leaf blight, and gray leaf spot. Soybeans had an average loss of around 13 million bushels from cercospora leaf blight, frog eye, and septoria brown spot.

Tar Spot
Fungicides are an excellent management tool for controlling yield-robbing diseases in corn and soybeans. Tar spot, for example is a disease that continues to spread and is becoming a consistent yield hitting disease most years. Areas with more susceptible hybrids, with later planted corn, or experiencing higher moisture or persistent leaf wetness are likely to experience tar spot and yield loss. Well-timed fungicides are critical for limiting tar spot and preserving yield.
Most Effective Practice
Significant disease pressure can cause a major impact on yield. A mixed mode of action fungicide product is the most effective fungicide practice to apply on your acres. Contact your Keystone representative to make a plan to control disease on your farming operation.
