    Starfruit is an exotic fruit with great nutritional, medicinal and economic benefits. Reports suggest that pests and diseases reduce the quality and yield of this crop. In Puerto Rico, there is an interest to increase production as the possibility of exporting the fruit to subtropical and temperate countries has been recognized. In order to identify potential pathogens that damage starfruit, samples were collected at the Tropical Agriculture Research Station farm (TARS) located in Isabela and the Corozal Experimental Substation. Three samples were collected (starfruit with disease symptoms) for each of the nine varieties following a pattern of stratified sampling in rows. The collected fruits were placed individually in plastic bags. The samples were processed and analyzed in the laboratory of BNF at Alzamora College Farm. The collected tissue surface was disinfected with a solution of sodium hypochlorite at 10%, 70% ethyl alcohol and rinsed with sterile distilled water for one minute. Disinfected tissue was transferred to Petri dishes that contained potato agar and dextrose, acidulated with lactic acid at 25%. In addition, moist chambers and observations under a microscope were done to identify the causative agent of the symptom. The fungal isolates were identified as; Fusarium sp., Trichoderma sp., Curvularia sp., Nigrospora sp.,Pestalotia sp., and Colletotrichum sp. Pathogenicity tests in vitro showed that the isolates of Fusarium, Pestalotia, Colletotrichum,and Nigrospora (detected only in ʻKariʼat Isabela) were pathogenic to fruit.
