High CO2 CA storage combined with biocontrol agents to reduce postharvest decay of pear.

Laboratory-grown yeasts (Cryptococcus laurentii, C. infirmo-miniatus and Rhodotorula glutinis) and the commercially available products BioSave 110 (Pseudomonas syringae) and Aspire (Candida oleophila) were applied to Bosc [Beurre Bosc] and Anjou [Beurre d'Anjou] pears by line spray and the fruits stored for 2, 4 or 6 weeks in atmospheres of either 5% O2/12% CO2 or 2% O2/3% CO2 before transfer to normal CA (2% O2/<5% CO2). Exposure to high CO2 atmospheres significantly reduced the percentage of wounds showing decay caused by Botrytis cinerea, with further rot inhibition provided by biocontrol agents. The best decay control was provided by exposures of 4 to 6 weeks in 5% O2/12% CO2, combined with laboratory-grown yeasts. This resulted in approx. 10-15% and 20-25% of infected wounds in Bosc and Anjou fruits, respectively, compared with >40% in fruits of both cultivars in normal CA. There was no indication of CO2 damage in the treated fruits.
