We were looking at some pearl millet on a plantation that has some leaf spots. Its planted next to soybeans which they thought may have been some spray drift. The browntop millet on the left is not affected. It’s actually a leaf spot disease. I once saw this in rice on a plantation a few miles away. The lesions on the leaves are elliptical or diamond shaped. Pyricularia leaf spot is also called rice blast on rice and is the same as grey leaf spot in turfgrasses. This is actually just grown for cover crop. The armyworms are causing more damage in other areas on the plantation than the leaf spot will do in this situation. Here is a link to Fungal Diseases of Pearl Millet.
