CARVALHO, Vicente Luiz de; CUNHA, Rodrigo Luz da; CHALFUN, Nilton Nagib Jorge  e  MOURA, Pedro Henrique Abreu. Alternatives for post-harvest control of brown rot and soft rot in peach fruits. Rev. Bras. Frutic. [online]. 2009, vol.31, n.1, pp.78-83. ISSN 0100-2945.  http://dx.doi.org/10.1590/S0100-29452009000100012.

The consumers demand are increasing with regard to the quality of in nature products. The rot, besides causing loss in production, reduce the quality of the product, interfering significantly in the marketing. The objective of this study was to evaluate the efficiency of alternative products, used during the post-harvest, in order to control the brown rot (Monilinia fructicola) and the soft rot (Rhizopus spp.) in peaches. The experiment was carried out in the municipality of Nepomuceno-MG in peaches of cultivar Diamond, of 10 years of planting. The experimental design was completely randomized, with 7 treatments and 3 repetitions. For the study, it was selected fruits without injuries and symptoms of the diseases. The fruits were immersed for 30 seconds in a solution containing the following treatments: 1- clove oil 0.01%; 2-Chlorine dioxide 0.1%; 3-Chlorine dioxide 0.05%; 4-Benzalkonium chloride 0.25%; 5-Dichloran 0.12%, 6-Iprodione 0.15% and 7-control (water only). After the treatments, the fruits, in a number of 10, were placed in sterile trays, in three replicates. The experiment was carried out in uncontrolled environmental conditions, the development of the diseases were evaluated 3 and 5 days after the treatments in 2005 and 3, 6 and 9 days after treatment in 2006. The use of Iprodione controlled the incidence and severity of M. fructicola and Rhizopus spp. The Dichloran was the most effective treatment in the control of Rhizopus spp. and intermediate in the control of M. fructicola. The treatments with clove oil and chlorine dioxide, at the highest concentration, reduced the incidence of Rhizopus spp. and to severity they showed intermediate results.
