Interpretive Summary:

Technical Abstract: Aflatoxin contamination is associated with wounding in pistachio nuts. The efficacy of P. anomala was assessed by artificially wounding pistachio nuts in the orchard. Production of A. flavus spores in wounded nuts sprayed with yeast was reduced by 77-99% compared to control. Furthermore colonization of A. flavus on wounded pistachio nuts was prevented by the presence of yeast on wounded nuts by 3-5 fold.
