Your corn, regardless of the field, is threatened by common stalk and ear disease each year. This is the second of a two-part series that looks closer at some of the most common stalk and ear disease as well as how to avoid them.
Yes, Stalk Rot Can Happen to Your Fields
Stalk rots can cause harvest loss, reduced yields, harvest issues, limited stand ability, and lodging.
Similar to ear rot, several factors determine the severity of the disease, including:
The susceptibility of stalk diseases varies greatly by hybrid, however environments such as corn-on-corn and reduced tillage increases the risk and severity of stalk diseases. Other conditions that pose a serious risk, include: low fertility, extremely high populations, damage from wind, hail, or tillage, and a tight husk.
Fusarium Stalk Rot:
Diplodia Stalk Rot:
Gibberella Stalk Rot:
Anthracnose Stalk Rot:
It’s Possible to Reduce Your Risk
One of the easiest ways to reduce the risk of stalk rot is to avoid planting corn-on-corn and take measures to limit insect wounds. Fungicide application early around v6-10 or during tasseling can reduce the severity of certain stalk rots.
The best course of action in the fight against Insect wounds is through planting SmartStax® or VT Double PRO® corn products, which can limit ear- and stalk-feeding insects. We also suggest getting every plant off to healthier start by choosing B&A Genetics hybrids with Protect ‘N Grow Seed Treatment using multiple fungicides to protect against many diseases in early development stages. Look for hybrids featuring a high tolerance to Anthracnose or other corn diseases. Feel free to reach out to the B&A Genetics team to help you make the right decisions for your fields.
