Effect of hot water brushing, prochloraz treatment and waxing on the incidence of black spot decay caused by Alternaria alternata in mango fruits.

A combined hot water spray and fruit brushing (hot water brushing-HWB) treatment for 15-20 s was developed for reducing the incidence of postharvest disease caused by Alternaria alternata and improving mango fruit keeping quality. The efficacy of the hot water treatment was tested over a range of temperatures from 48 to 64 degrees C, in combination with prochloraz treatment and fruit waxing. Hot water brushing of fruits significantly reduced decay (infected area) development by A. alternata. But after storage for 3 weeks at 12 degrees C and another week at 20 degrees C, the reduction of disease incidence by HWB and prochloraz treatment (900 micrograms ml(-1)) was more effective than by HWB alone. HWB treatment for 15 s improved colour development and was more effective than the common, commercial 5 min dip treatment at 55 degrees C. The combination of fruit HWB and waxing yielded high quality fruits with less decay development.
