The objective of this study was to evaluate severity, effectiveness, and the area under the disease progress curve (AUDPC) of chemical four fungicides (A+F=azoxystrobin + fludioxinil, C+F=cypronil + fludioxinil, B+P=boscalid + pyraclostrobin and T=tiabendazole) at 250, 500, 750, and 1000 ppm against Colletotrichum gloeosporioides in papaya. At 12 days after inoculation (dai) A+F achieved a range of effectiveness between 63.0 (250 ppm) to 77.52 (1000 ppm); while the range of effectiveness for T was 12.8% (250 ppm) to 74% (1000 ppm). Both fungicides achieved the highest effectiveness at 1000 ppm that C+F (38.5%) and B+P (55.6%). The AUDPC achieved the same value at the four studied concentration in A+F, C+F, and B+P. Only 750 and 1000 ppm of T achieved the lowest AUDPC than 250 and 500 ppm. In conclusion, A+F and T achieved adequate control of anthracnose in papaya fruits.
