cotton
Cotton rust. The pycnial lesions on the upper surface of cotton leaves are sometimes surrounded by a maroon zone. The aecia are commonest on the leaves but many occur on stems and severe infection causes defoliation. Carpel infection leads to dwarfing of the locules and attacks on the peduncle contribute to breakage and loss of bolls. Infection of cotton seedlings may cause death
