How to prevent calyx disorders associated with citrus degreening?

During de-greening, citrus fruits are exposed to high relative humidity and temperature conditions. These conditions can promote pathogen growth, increasing the likelihood of citrus rot development. Rotting causes significant economic losses for producers. The application of ethylene during citrus de-greening to induce color change in the flavedo accelerates the drying of the calyx area, typically leading to darkening and inevitable detachment. Susceptibility to this physiological disorder depends on factors such as: Variety Duration of ethylene exposure (De-greening process duration) Temperature and humidity Air renewal speed In the past, the use of effective products like 2,4-D (2,4-dichlorophenoxyacetic acid) was widespread, but it is not authorized for post-harvest use in the EU. Due to this prohibition and the issue of citrus calyx drop, which diminishes their commercial value, DECCO worked to find a legal and effective solution. Development studies and successful campaigns have reported the positive effect of DECCO Green (3,5,6-trichloro-2-pyridyloxyacetic acid) application in preventing calyx disorders associated with de-greening. Using the drencher is highly recommended to protect fruits before de-greening, minimizing the risk of infections and physiological disorders. DECCO Green: Fruit Protection and Improvement DECCO Green provides several benefits for protecting citrus quality during de-greening. Its application reduces calyx darkening and drop, preventing damage to the fruit structure. Additionally, it significantly improves the visual appearance of the fruit by reducing skin senescence, providing a fresher and more attractive look. DECCO Protect Drencher: Enhancing Fruit Appearance by Reducing Senescence The DECCO Protect Drencher enhances the citrus's freshness appearance, specifically designed for use during de-greening and bunch packaging. Developed for application in the drencher, the benefits of using DECCO Protect Drencher include: Enhancing the fruit's appearance and freshness by reducing the oxidation of skin cells damaged by impacts or abrasions. No marking required. As the de-greening process is complex, DECCO is at your disposal to guide and advise you because your citrus deserves the best.
