Goss's Wilt

DEKALB® Disease Shield™ 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, and other environmental risk factors, but it results in an average yield loss of 11.6% (or 18.5 Bu/A).

​Northern Corn Leaf Blight

DEKALB® Disease Shield™ 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).

Gray Leaf Spot

DEKALB® Disease Shield™ offers the genetics you need to help keep Gray Leaf Spot from spreading to your acres and limiting your yield potential.

This disease causes an average 6.1% yield loss (or about 9.8 Bu/A). Gray leaf spot thrives in humid, warm climates, especially when 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.

Anthracnose Stalk Rot

DEKALB® Disease Shield™ 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 for yield loss (or about 9.7 Bu/A), anthracnose stalk rot is a powerful threat to corn growers 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.

Southern Rust

DEKALB® Disease Shield™ 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% (or 5.0 Bu/A) average loss 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.
