“…However, plant volatiles are currently gaining global interest due to their volatility, safety, eco‐friendly and antimicrobial properties, and they have been classified on the GRAS (Generally Regarded as Safe) list as food additives by the USFDA (Abbaszadeh, Sharifzadeh, Shokri, Khosravi, & Abbaszadeh, ; Wuryatmo, Able, Ford, & Scott, ; Zhou, Tao, & Jia, ). Reports have established the efficiency of various plant volatiles in mangoes (Anusuya et al., ), guava (Gill, Dhaliwal, Mahajan, Paliyath, & Boora, ) and citrus (Fan, Tao, Jia, & He, ; Tao, Jia, & Zhou, ; Tao, OuYang, & Jia, ; Wuryatmo et al., ) for the reduction in postharvest incidences, prolonged shelf life and improvement of fruit quality. Therefore, this investigation involves three objectives, namely [i] to investigate the antifungal activities of the selected natural plant volatiles against L. theobromae in avocado cultivars in vitro primarily on the radial mycelial growth and spore germination, [ii] to observe the impact of selected promising volatile citral in artificially infected healthy fruit in vivo on the incidence of stem‐end rot at two retail shelf conditions of 6 days 20°C and 14 days at 10°C and [iii] to determine the eliciting effect of citral on the defence‐related enzymes in preventatively treated fruit.…”
