Bacterial leaf streak is a relatively new bacterial disease attacking many cornfields in the U.S. It was first discovered a few years ago in Nebraska and has since spread to several states. Although there’s still quite a bit to learn about its effect on yields, it’s important for farmers to be proactive in protecting themselves against potential loss. The best way to do this is with adequate crop insurance. Below is an overview of what growers need to know about the disease. 

What It Looks Like 

Bacterial leaf streak has distinct characteristics that farmers should watch for. In its early stages, the disease causes narrow yellow or brown streaks to form on the plant’s leaves.

The biggest challenge for many has been distinguishing between this disease and the fungal disease known as gray leaf spot. However, whereas bacterial leaf streak creates wavy-edged lesions, gray leaf spot is recognizable by its straight-edged lesions. Additionally, when a leaf is held up in the sunlight, the lesions from bacterial leaf streak will be translucent, while those from gray leaf spot are more opaque. 

Why It’s Harmful 

To grow successfully, plants require an abundance of nutrients from the soil. They receive this through the process of photosynthesis, which primarily occurs in green leaves.

When bacterial leaf streak begins discoloring plant leaves, it prevents them from getting all the nutrients they need to stay healthy. In turn, this can negatively impact the crop’s yield potential. Unlike other types of diseases found on plant leaves, bacterial leaf streak can’t be treated with fungicides. As such, purchasing crop insurance is currently the most effective solution farmers have for minimizing loss.
