Abstrack Pamelo (Citrus maxima) is native to Southeast Asia, and the contribution of South Sulawesi nationally as a producer ranks first at 30.76%. The purpose of this study was to determine the intensity of stem rot disease on Pomelo in Ma’rang, Labakkang, and Segeri Districts of Pangkep Regency. After calculating the disease severity, samples were taken on the symptomatic tissue, then the disease-causing pathogens were isolated and purified, followed by microscopic observation at the Laboratory of Pest and Plant Diseases, Hasanuddin University. The results showed that the highest stem rot disease intensity was in Ma’rang District on red and white Pomelo varieties at 53% and 44%, followed by Labakkang District at 33% on red Pomelo and 26% on white Pomelo. The lowest disease severity was in Segeri District with 30% on red and 24% on white Pomelo. Pomelo citrus production in Ma’rang District was 92.72 tons/ha, Labakkang 213.51 tons/ha, and Segeri District 259.40 tons/ha. These data indicate that the intensity of disease severity and land conditions affect the production of Pomelo in the three sub-districts observed.
