Among the fungal diseases as smallpox (Asperisporium caricae) is the most important diseases of papaya. Objectives of this article were to evaluate the efficacy of fungicides to control smallpox papaya. The experiment was conducted in a commercial area in the municipality of Taquarintiga - SP in RBD with five treatments and four replications. The treatments were Tebuconazole + trifloxystrobin (0.06 L / 100L), Pyraclostrobin (0.04 L/100L) Difenoconazol (0.03 L/100L), Azoxystrobin and a witness. Were performed 3 evaluations, which were evaluated the severity of smallpox through diagrammatic scale, on leaves and fruits of three plants previously marked and on each assessment two leaves and four fruits were chosen randomly and evaluated. The data were subjected to analysis of variance by F test and means compared by Scott-Knott test (p <0.05). The products Tebuconazol + trifloxystrobin, Pyraclostrobin, Difenoconazol and Azoxystrobin controlled smallpox, but were not effective for control of anthracnose.
