ABSTRACT:     The pomegranate is a fruit with high productive potential; however, the hot and humid climate favors the occurrence of diseases that cause spots on the fruit peel, reducing their commercial value. Therefore, this study aimed to evaluate different controlling methods of spots on pomegranate fruit under field conditions and their relation with the diseases incidence during the postharvest. The experiment consisted of the following treatments: Test: control group; VM: Viçosa mixture; MZ: Mancozeb; MZ+PC: Plastic cover + Mancozeb; CZ: Carbendazim; KP: Potassium phosphite; P+C: Picoxystrobin + Ciproconazole. Evaluations were performed at 29, 51, 57, 65 and 72 days after application. The treatments MZ, MZ+PC and CZ were more efficient in reducing the severity and incidence on field, with AUDPC-Sev of 67.50; 89.72 and 198.33, respectively. At the post-harvest treatments MZ+PC, MZ, CZ and P+C, the rates of fungal incidence were lower, with 29.2, 37.5, 45.8 and 62.5%, in that order. A linear relationship was found between severity and spots incidence on field with the fungi incidence during postharvest. The Mancozeb treatment was efficient in controlling fruit spots, in addition to reducing the occurrence of diseases during the postharvest of pomegranate.

RESUMO:     A romã é um fruto de alto potencial produtivo, todavia, o clima quente e úmido favorece a ocorrência de doenças que causam manchas nas cascas dos frutos, reduzindo o valor comercial. Assim, o objetivo do trabalho foi avaliar diferentes métodos de controle de manchas em frutos de romã sob condições de campo, e sua relação com a incidência de doenças em pós-colheita. O experimento foi composto pelos seguintes tratamentos: Test: Testemunha; CV: Calda Viçosa; MZ: Mancozeb; MZ+CP: Cobertura plástica + Mancozeb; CZ: Carbendazim; FK: Fosfito de potássio; P+C: Picoxistrobina + Ciproconazole. As avaliações foram realizadas aos 29, 51, 57, 65 e 72 dias após a aplicação. Os tratamentos MZ, MZ+CP e CZ foram mais eficientes para redução da severidade e incidência a campo, com AACPD-Sev de 67,50; 89,72 e 198,33, respectivamente. Em pós-colheita os tratamentos MZ+CP, MZ, CZ e P+C apresentaram menor incidência de fungos, com 29,2, 37,5, 45,8 e 62,5%, nesta ordem. Foi observado relação linear entre a severidade e a incidência de manchas no campo com a incidência de fungos em pós-colheita. O tratamento com Mancozeb foi eficiente no controle das manchas nos frutos, além de reduzir a ocorrência de doenças em pós-colheita de romã.
