Abstract: In C?te d'Ivoire, the control of chemical fungal diseases poses residue problems on the papaya. Thus, the use of plant extracts is proving to be a recommended alternative. The objective of this work is to contribute to the fight against postharvest fungal rot of papayas through the use of plant extracts. The effects of aqueous extracts of seeds of Azadirachta indica, Ricinus communis and Jatropha curcas at concentration of 50, 125 and 250 mg / ml were determined in three fungal genera, namely Fusarium, Phytophthora and Colletotrichum isolated from papaya. Aqueous extracts of Jatropha curcas and Ricinus communis completely inhibited mycelial growth of the three fungal genera at a concentration of 250 mg / ml. The papayas remained rot-free in the presence of seed extract of Ricinus communis and Jatropha curcas at the same concentration. However, the toxicity of these extracts should be evaluated.
