Introduction. In-package biofumigation with the volatile-producing fungusMuscodor albus was tested to control fungal decay in organic tablegrapes stored at a commercial packinghouse. Materials and methods. Sachetscontaining two different amounts of activated M. albus culture wereinserted into shipping boxes containing approximately 4.5 kg of ‘Thompson Seedless’ or‘Red Seedless’ table grapes. The volatiles were contained inside the boxes either bywrapping pallets of the boxes externally with plastic film after pre-cooling (palletwrapping) or by using a modified atmosphere liner inside each box. Decay incidence wasevaluated after 7 weeks of storage at 0 °C. Results. TheM. albus sachets reduced decay incidence among ‘Red Seedless’ tablegrapes in both wrapped pallets and boxes with liners. In this cultivar, the modifiedatmosphere liner alone reduced decay incidence by about 70% and the M. albustreatment in the liner further reduced decay incidence, regardless of the amountof M. albus used. The combination of the M. albus sachetand the modified atmosphere liner proved to be the most effective decay control treatment.Decay incidence was lower among ‘Thompson Seedless’ table grapes and a significant decaycontrol was only observed after the grapes had been allowed to warm up after storage withthe 50-g rates applied inside the liner. No adverse effects were associated with thetreatment or the liners. Discussion. Based on our results, biofumigation withM. albus sachets is compatible with the commercial handling of organictable grapes and could provide significant improvement in their shelf life.
