Chemical control and refrigeration are two processes usually adopted in the treatment of the banana post harvest rot. This work has for objective to evaluate the effect on the control of the anthracnose in banana post harvest of the chemotherapy, of the thermotherapy, of the combination of the two listed methods and these all associated to the low conservation temperature. The experiments were replicate three times where banana fruit (Musa sp) of the variety 'Prata Anã' (AAB) were collected in the pre-climateric stage. The fruits were submitted to four treatments with five replications. 1. thermotherapy (immersion in hot water at 56ºC for six minutes, followed by immersion in water at home temperature), 2. chemical control for six minutes (immersion in fungicidal suspension (prochloraz 2.5 mL.L-1)), 3. thermotherapy followed by the chemical control, 4. Negative control, immersion water at home temperature for six minutes. After the treatments, the hands was divided in half parts, one part was put in cold camera (14ºC with variation of 2ºC) and the other one stayed at home temperature. The thermotherapy wasn't effective to control of the disease. The fungicide prochloraz at 2.5 mL.L-1 was efficient in the control of the banana post harvest rot. The refrigeration delayed the presence of the disease in up to 12 days. The results indicate that the low temperature, associated or not to the chemical control, can control the fruits post harvest rot for 12 days.
