Identify the Top Five Yield-Robbing Diseases

DEKALB Disease Shield works hard to deter harmful diseases, including Goss’s wilt, northern corn leaf blight, gray leaf spot, anthracnose stalk rot and southern rust. Learn how to identify these common diseases and manage their risk factors.

Goss's Wilt

DEKALB® Disease Shield® technology offers the genetics you need to help keep Goss's wilt from spreading to your acres and limiting your yield potential.

Over the past 50 years, Goss's wilt has spread from the western Corn Belt across 18 states and into Canada. Its impact on yield varies based on rain, hail and wind damage, as well as other environmental risk factors, but it results in an average yield loss of 11.6% (or 18.5 bu/A).


What to look for:

  • Discolored vascular tissue

  • Browning of lower stalks

  • Watery lesions with wavy margins (gray-green to black in color)

  • Leaves with smaller "freckles" inside larger lesions that may be visible when held up to the sun

Northern Corn Leaf Blight

DEKALB® Disease Shield® technology offers the genetics you need to help keep northern corn leaf blight from spreading to your acres and limiting your yield potential.

As its name indicates, northern corn leaf blight is more common in the early summer climates of Midwestern states due to high humidity and moderate temps. But it can also be a springtime problem in southern and central Florida. On average, it can reduce yields by 7.4% (or 11.9 bu/A).

What to look for:

  • Greenish-gray lesions shaped like ovals or cigars, first appearing on lower leaves and moving upward into the canopy
  • Lesions can be up to 6 inches long

Gray Leaf Spot

DEKALB® Disease Shield® technology offers the genetics you need to help keep gray leaf spot from spreading to your acres and limiting your yield potential.

Causing an average 6.1% yield loss (or about 9.8 bu/A), gray leaf spot thrives in humid, warm climates, especially when the sky is overcast for days at a time. Crops throughout the Corn Belt are susceptible to it, but especially in the eastern Corn Belt and Mid-Atlantic states.

What to look for:

  • Small brown rectangular lesions surrounded by a yellow halo on the leaves

  • Brown or gray regions between major leaf veins

  • Gray fungal spores on the underside of leaves

Anthracnose Stalk Rot

DEKALB® Disease Shield® technology offers the genetics you need to help keep anthracnose stalk rot from spreading to your acres and limiting your yield potential.

With a 6.1% average yield loss (or about 9.7 bu/A), anthracnose stalk rot is a powerful threat to corn farmers across the nation. In fact, up to 65% of all U.S. acres are at risk. Anthracnose stalk rot likes to grow in warm temperatures with high humidity, especially in high-yield environments and high-density acres. Also notable: It can infect plants through the roots or by spores landing on the stalk.

What to look for:

  • "Ghosting" or dieback

  • Rotted stalks

  • Dark and soft tissues starting at the nodes

  • Shiny black discoloration in blotches or streaks on the stalk (also called blackened rinds)

  • Lodging high on the stalk

  • Early drydown

Southern Rust

DEKALB® Disease Shield® technology offers the genetics you need to help keep southern rust from spreading to your acres and limiting your yield potential.

It might not be talked about as much as other diseases, but southern rust can still take a big chunk out of yield potential. It accounts for 3.1% average yield loss (or 5.0 bu/A) due to its ability to inhibit photosynthesis and starch production. Growers in the southern part of the Corn Belt are at risk the most because southern rust likes warm and humid climates.

What to look for:

  • Small circular pustules with light-orange to reddish coloring located on the upper leaf surface

  • Pustules may also infect stalks, husks, ear shanks and husk leaves

  • Weakened stalks and accompanying stalk rot
