Abstract: Cotton (Gossypium hirsutum L.) is one of the most important fiber crop playing a key role in the economic and social scenario of the globe. It is also known as “The white gold” or “The king of fibers”. It is a premier cash crop of our country and belongs to the family malvaceae. Curvularia leaf spot appear initially as small circular brown to brownish black spot surrounding with yellow, later it become dark yellow to brown hallow surrounding to brownish black spots and in severe cases, the leaves turned yellow colour and detached easily from the branch resulting in the defoliation. The survey was conducted in the cotton growing regions of Surat, Bharuch and Narmada districts of South Gujarat in the year 2024-25 to examine the presence of Curvularia lunata (Wakker) Boedijn pathogen on cotton plants and to record the observation on per cent disease intensity and per cent disease incidence The maximum mean per cent disease intensity was found in the Bharuch district with 32.64 per cent, while the lowest disease intensity of Curvularia lunata was found in Surat district with 17.45 per cent and the maximum per cent disease incidence was found in Bharuch district with 12.33 per cent, while the lowest per cent disease incidence was found in Surat district with 7.22 per cent.
