ABSTRACT
Papaya crop (Carica papaya L.) faces pathologies mainly of fungal etiology. Colletotrichum gloeosporioides (Penz.) Sacc., causal agent of anthracnose, represents one of the most severe diseases that reduce the productivity of plantations. For this reason, the present study was carried out on one hectare of papaya cultivar 'Maradol Roja' at the Research Institute of Tropical Root and Tuber Crops (INIVIT), with the objective of evaluating the technical effectiveness of the fungicide Sphere Max 535 SC (trifloxystrobin + ciproconazole) for the control of anthracnose at doses of 0.2 and 0.3 L ha-1 and Biobeno (Benomilo), the latter as a commercial reference. A completely randomized design was used; five applications were made with a frequency of 20 days. The severity of the disease was evaluated, as well as the technical effectiveness of the formulations used. The severity increased gradually, reaching its maximum values at 100 days. In the plots treated with Benomilo, the severity of the disease was higher, reaching an average of 22.3 %. The variants corresponding to Sphere Max 535 SC were more effective than Benomilo, with values of 57,8 and 61,5 % of effectiveness, respectively.
