“…Apesar de estudos demonstrarem a eficiência no controle da antracnose por meio de métodos alternativos à utilização de fungicidas (Lima et al, 2007;Nolasco et al, 2008), este ainda é o mais comum.…”

RESUMOA antracnose é uma das principais doenças após a colheita da banana, causada pelas diferentes raças fisiológicas do fungo Colletotrichum musae, e que se manifesta na maioria das vezes na fruta madura, comprometendo a sua qualidade. Seu aparecimento está relacionado ao manuseio inadequado, ausência de controle químico em campo e de refrigeração. A aplicação de produtos químicos é efetuada durante o beneficiamento, sendo importante salientar que pode iniciar com a fruta ainda no campo. Objetivou-se, neste trabalho, verificar o efeito de fungicidas utilizados após a colheita, visando o controle da antracnose em bananas, cultivar Prata Anã, armazenadas a 20°C e 12°C. Para isso, foi testada a ação dos fungicidas tiabendazol e imazalil no controle de Colletotrichum musae. No teste, foram empregados isolados das cultivares Prata Anã, FHIA 02 e ST 4208, inoculados em bananas-prata anã. As avaliações foram efetuadas a cada 3 dias, por meio de medições do tamanho das lesões (mm 2 ), sendo as frutas inoculadas descartadas no estádio de maturação 7 (amarelo com pontas marrom). Os tratamentos mais eficientes no controle da doença foram aqueles em que as bananas foram tratadas com o fungicida tiabendazol. No estudo, também foi verificada diferença em relação à patogenicidade dos isolados utilizados, que demonstraram especificidade quanto a cultivar.Termos para indexação: Musa sp. , doenças pós-colheita, antracnose, controle químico. ABSTRACTAnthracnose is one of the main post-harvest disease of the banana, caused by different physiological races of Colletotrichum musae. It manifests itself mostly in ripe fruits, threatening its quality. Its appearance is related to the inadequate handling, absence of chemical control in field, and cooling. Application of chemical products is usually done during the processing, but it is important to point out that it can be done while the fruit is still in the field. This work had as an objective to verify the effect post-harvest application of fungicides to control anthracnose in Dwarf Silver bananas, stored at 20°C and 12°C. To that end, the influence of the thiabendazole and imazalil fungicides was tested on Colletotrichum musae. In the tests we employed Dwarfed Silver isolates of cultivars FHIA 02 and ST 4208 inoculated in Dwarfed Silver bananas. The evaluations were done every 3 days, by measuring the size of injuries (mm 2 ). The inoculated fruits were discarded in the stage 7 of maturation (yellow with brown tips). The most efficient treatments in disease control were those in which the bananas were treated with the thiabendazole fungicide. The difference in relation to the pathogenicity of the isolates used, demonstrated the specificity of the cultivar.

“…13). Thus, fruits at a more advanced maturation stage tend to lose membrane integrity and have a faster electrolyte extravasation compared to those at an earlier maturation stage [29]. According to (Pinheiro et al) [30], working with "Prata-Anã" banana submitted to hydrothermal treatment, the same behavior was observed, increased extravasation of electrolytes throughout the days after fruits were removed from the cold chamber, regardless of immersion temperature.…”

Objective: To determine the ideal harvest season of ‘Prata-Anã’ banana bunches by means of physical and chemical analyses of fruit cultivation conditions in the northern state of Minas Gerais. Study Design: The employed experimental design was the completely randomized design was used in a 5x5 factorial scheme, with five bunch ages and five assessment days. Study Location and Duration: The experiment was run in an area with banana trees planted 20 months beforehand, located at Unimontes’s Experimental Farm, at 530 m of altitude, with coordinates being -15°43’46.99” south latitude and -43°19’17.61”west longitude, between April and November 2017. Methodology: The bananas bunches the were marked weekly from April 14 to May 12, and week days were standardized for each marking. Five bunch ages were defined – 16, 17, 18, 19 and 20 weeks after inflorescence emission – for harvest. For differentiation of emerged bunches, tapes of different color were used. When the bunches marked in the first week completed 20 weeks, all bunches were harvested, which happened on September 1. After harvested the fruits were subjected to storage in refrigerated chamber at 10°C ± 1°C and relative humidity of 90% +5% for 25 days. After being stored for 25 days, the bananas were taken out of the chamber and exposed to a room temperature of 25°C, which analyzes were performed for 9 days, with a two-day interval in between, simulating the marketing period. The following analyses were carried out: Firmness, peel color, soluble solids, pH, titratable acidity, amide, total sugars, reducing sugars and electrolyte extravasation. Results: Lower hue, chroma, soluble solids, titratable acidity, total sugar, reducing sugar and electrolyte extravasation values were found for bananas harvested at 16 weeks. Conclusion: Bunch harvest age had a direct influence on post-harvest quality of bananas ‘Prata-Anã’. Fruits from 16-week bunches were superior in physical and chemical characteristics compared to other ages, meaning a longer post-harvest life.
