Low-Temperature Phosphine Fumigation Is Effective Against in Sweet Cherry.

, classified as a quarantine pest in some countries, poses a serious threat to global trade due to its ability to damage berries and cherries. Recent studies indicate that low-temperature phosphine (PH) fumigation effectively controls this pest without compromising fresh produce quality. However, the specific protocol for managing larvae in cherries using this method remains underexplored. This study evaluates the efficacy of low-temperature PH fumigation in controlling larvae across three cherry varieties at 3 °C and investigates potential effects on key quality metrics. Tolerance assessments revealed that 3rd instar larvae exhibit the highest resistance to PH among all developmental stages. A concentration of 800 mL/m PH for 84 h at 3 °C achieved phytosanitary efficacy for 0.99997 with no negative effect on the quality attributes of the tested cherry varieties. These results support low-temperature PH fumigation as a viable postharvest treatment for management in sweet cherries.
