Complete answer:
Cercospora genus are the plant pathogens that cause diseases in the peanut plants which belong to the family of leguminosae. They cause tikka or leaf spot disease. Plants suffering from this disease have dark brown or black spots are formed on the upper and lower surface of the leaf. This infection leads to the early death of the leaves or plants which results in low yield.

Additional information:

The difference is that Cercospora arachidicola appears in the initial stages of the growth of the plant and they cause the brown spots which have a yellow halo lining on the leaf. Whereas, Cercospora personata appears in the later stages of the plant growth which develops dark brown or black spots on the surface of leaves. They may or may not have the yellow halo around the dark spots.
