Volatile organic compounds (VOCs) produced by microorganisms may prevent postharvest rot in fruits. Here, it was examined if VOCs from different species of can control infection in apples caused by the fungal pathogen . Incubation of -infected apples in semi-closed boxes with actively growing strains of three ( and strain 2R) showed that VOCs reduced rot areas of the apples by 45-66% after 8 days and 39-57% after 10 days, relative to infected apples incubated without . No differences in inhibition among the three strains were seen. In contrast, a mutant strain of that lacks major genes involved in biosynthesis of secondary metabolites, did not reduce development of rot in the apples. Furthermore, VOCs reduced radial hyphal growth of on agar. Several of the VOCs produced by three strains have previously shown fungicidal properties. Although the specific VOCs being active in inhibition of remain to be determined, VOCs may have a great potential as biofumigants to minimize postharvest diseases in fruits.

As the global population continues to grow, the use of pesticides to increase food production is projected to escalate. Pesticides are critical in plant protection, offering a powerful defense against fungal diseases such as apple scab, leaf spot, sclerotinia rot, damping off, sheath blight, and root rot, which threaten crops like cereals, corn, cotton, soybean, sugarcane, tuberous vegetables, and ornamentals. Succinate Dehydrogenase Inhibitor (SDHI) fungicides represent a novel class essential for controlling fungal pathogens and bolstering food security.

Although a major share of postharvest losses of apples is due to fungal fruit rots, their timely detection is difficult in commercial bulk-storage rooms. Therefore, a method was developed to identify the volatile markers of fruit naturally infected by Phacidiopycnis washingtonensis, a common storage-rot fungus of Northern Europe, and North and South America. Potato dextrose agar, apple juice agar, and fruit of the apple cultivar 'Nicoter' were inoculated with P.
