Testing for Goss's Wilt

Goss's Wilt (Clavibacter Michiganensis Nebraskensis) has been prevalent in the US mid-West for years, and spreading in all directions. It is becoming more common in many other areas of the country, including the upper plains, the intermountain west, south, and more. If you know what to look for, it is simple to spot, and there are some very simple tests to confirm the infection. The information below helps you identify the symptoms and also shows you how to operate a simple on-farm test to confirm your diagnosis. If you have identified Goss's Wilt on your farm, Call Us. We can help you eliminate it. Our Healthy to Harvest program includes nutrition and Bio-Empruv, all designed to increase yields and prevent disease.

As you inspect the plants, you will see brown and pinkish-brown lesions on both the stems and the leaves. If you peel back the leaves around the ears you will see the lesions very clearly on the inside. The plants tend to die from the top down, so the corn stalks will be dead and dry on top and the death will work its way down to the base. Since it is a vascular disease, it prevents the movement of nutrients, so the ears don't have a chance to develop properly, leaving unfilled tips and/or undersized ears.
