SILVA, LAIS MAIA E et al. TEMPORAL PROGRESS AND CONTROL OF ANTHRACNOSE ON BANANA IN SEMIARID IN THE NORTH OF MINAS GERAIS. Rev. Bras. Frutic. [online]. 2016, vol.38, n.1, pp.81-91. ISSN 0100-2945.  http://dx.doi.org/10.1590/0100-2945-299/14.

Anthracnose is one of the major post harvest diseases of bananas. The study aimed to evaluate for ten months the intensity of the anthracnose and the effect of washing and sanitizing of the fruits in the disease control on the post harvest of bananas. The experiment was conducted from September 2013 to June 2014. The samplings of the fruits were held monthly in five commercial properties located in the cities of Jaíba, Janaúba and Nova Porteirinha, cultivated with banana “Prata-Anã”. The bunch of bananas were subdivided into bouquets of three fruits, the experimental design was entirely randomized in factorial scheme and subjected to the treatments: fruits without the realization of the washing (control); fruits washed in the property; fruits washed in the laboratory with sodium hypochlorite at 2%; fruits washed in the laboratory with sodium hypochlorite followed by 2% Imazalil fungicide application. The evaluations were performed in 10 seasons, and the treatments replicated five times. It was calculated the area below the intensity progress curve (ABIPC) and the area below the severity progress curve (ABSPC).The results obtained were subjected to analysis of variance and average compared by the Scott-Knott test at 5% of probability. The highest intensity of anthracnose on bananas in North of Minas Gerais occurred in the months of November 2013 to March 2014. The lower intensity occurred in the months of September and October 2013 and from April to June 2014. In the months from November to March, period of higher intensity of the disease, the washing of the fruits with neutral detergent and sodium hypochlorite at 2% followed by application of Imazalil fungicide is the most efficient control technique. Washing of fruit, only with neutral detergent may increase the incidence of anthracnose, a deterioration of the cuticle.
