Cadophora luteo-olivacea, known for causing skin-pitting, is a as a key threat to postharvest storage of kiwifruit. Through both in vitro and in vivo tests, this study aimed to determine the the antifungal ability of volatile organic compounds (VOCs) produced by Bacillus pumilus QST2808 for controlling this postharvest pathogen fungal pathogen. In vitro results showed  52% reduction in fungal growth when exposed to these VOCs for 14 days. In storage trials, kiwifruits treated with VOCs showed a 28.5% decrease in disease severity after 96 hours of exposure compared to the untreated control, followed by three months in cold storage. However, this reduction was not statistically significant (p > 0.05). These findings highlight the potential of B. pumilus QST2808 VOCs as an eco-friendly biofumigation approach to manage C. luteo-olivacea-induced postharvest skin-pitting disease in kiwifruit. https://www.biotech-asia.org/vol22no3/suppression-of-postharvest-skin-pitting-disease-in-kiwifruit-by-volatile-organic-compounds-vocs-from-bacillus-pumilus-qst2808/ Biofumigation; Biological control; Bacillus pumilus; Kiwifruit; Postharvest
