SANTOS, Alice Maria Gonçalves; LINS, Severina Rodrigues Oliveira; SILVA, Josenilda Maria da  e  OLIVEIRA, Sônia Maria Alves de. Low doses of gamma radiation in the management of postharvest Lasiodiplodia theobromae in mangos. Braz. J. Microbiol. [online]. 2015, vol.46, n.3, pp.841-847.  Epub 21-Jul-2015. ISSN 1517-8382.  http://dx.doi.org/10.1590/S1517-838246320140363.

The postharvest life of mango is limited by the development of pathogens, especially fungi that cause rot, among which stands out the Lasiodiplodia theobromae. Several control methods have been employed to minimize the damages caused by this fungus, chemical control can leave residues to man and nature; physical control by the use of gamma radiation in combination with modified atmosphere and cold storage. The use of gamma radiation helps to reduce the severity of the pathogen assist in the ripening process of fruits, even at low doses (0.25, 0.35 and 0.45 kGy) chemical properties such as pH, soluble solids, acid ascorbic, titratable acidity and also the quality parameters of the pulp showed no damage that are ideal for trade and consumption of mangoes. This treatment can be extended for use in the management of diseases such as natural infections for penducular rot complex that has as one of L. theobroma pathogens involved.
