Biocontrole pós-colheita da podridäo de Lasiodiplodia em frutos de manga por leveduras saprofíticas / Postharvest biocontrol of Lasiodiploidia rot of mango fruits by saprophytic yeasts

RESUMO

Among eigtheen yeast isolates studied as potential agents for biocontrol of stem-end rot on mango fruits caused by Lasiodiplodia theobromae, five were selected for testing in relation to three pathogen concentrations (1x10ü, 1x10 elevada à quarta and 1x10 elevada à quinta conidia/ml). The isolate LM-5 (Candida maritima) showed high control level at all pathogen concentrations. When tested against five pathogen isolates, LM-5 again demonstrated high control efficiency, and at in vitro test, highlyinhibited L.theobromae spore germination. The isolate LM-5 demonstrated great potential as agent for postharvest biocontrol of mango rot
