Early leaf spot

Cercospora arachidicola

It can be difficult to distinguish between symptoms of early and late leaf spot. Early leaf spot usually causes brown lesions (spots) that are surrounded by a yellow halo. Although early leaf spot can be found as early as 30 days after planting, first lesions often are not observed until mid-July. Early leaf spots produce tufts of silvery, hair-like spores on the top of the leaf.
