[caused by Puccinia arachidis]
Rust is a rare disease on peanut in the V-C area. If present, it usually is seen late in the fall following a tropical storm. Spots are yellow on the upper leaf surface, and rusty orange to brown on the lower leaf. Loose and powdery spores are found on the lower leaf surface. The disease spreads rapidly but usually is not damaging in the V-C area due to late onset.
