Biocontrol activity of Bio-Coat and Biocure against postharvest rots of table grapes and sweet cherries The efficacy of two postharvest biocontrol products under commercial development was setermined in semi-commercial tests o­n table grapes and sweet cherries. The products consist of the yeast Candida satioana combined with either chitosan (Bio-Coat) or an antifungal, lytic enzyme (Biocure).

On table grape (cv Italia) field applications of the two biocontrol products 21 days and 1 day determined significant reduction of grey mould rots after storage and shelf-life ranging, from 33 to 46%. Field rots (mainly sour rot) were also reduced o­n bunches of grapes treated 21 days before harvest. The level of control was comparable to that of a conventional chemical fungicide (Mepanypirim). o­n sweet cherries (cv Lapins) postharvest dipping treatments significantly reduced total rots (mainly grey and brown mould) by 59% (Bio-Coat) and 64% (Biocure). Similar results were obtained o­n sweet cherries cv Moreau.

The two biocontrol products did not cause any phytotoxic effect and did not modify the fruit appealing o­n both table grapes and sweet cherries.
