“…Previously, it was shown that vaporized thymol could control postharvest decay for the cherries inoculated with Botrytis cinerea [17], but our study is the first time it has been presented that thymol inhibited the disease-causing pathogens on cherries inoculated with M. fructicola. Our study also showed that thymol caused more severe phytotoxicity than acetic acid.…”

Fumigation of sweet cherries with low levels of thymol and acetic acid to reduce postharvest brown rot and blue mold rot.Abstract -Introduction. Sweet cherries are susceptible to postharvest decay. The use of synthetic fungicides is discouraged in postharvest handling because they can leave a residue and present a safety risk. Therefore, naturally occurring compounds have been considered as an alternative. Fumigation of short-chain organic acids and essential oils has shown promise in controlling fungal activities. This study reports their effects on sweet cherries. Materials and method. 'Hedelfingen' sweet cherries (Prunus avium L.) were inoculated with conidia of Monilinia fructicola and Penicillium expansum, then fumigated with three levels of thymol or acetic acid for 10 min before cold storage. Results and discussion. After 13 d at 10 °C, sweet cherries fumigated with 10 mg × L -1 of thymol significantly reduced brown rot from 21% to 12%, but had no effect on reducing blue mold rot. Fumigation with 6 or 10 mg × L -1 acetic acid significantly reduced blue mold rot from 16% to 2%, but had no effect on reducing brown rot. Fumigation did not have any effect on the firmness, total soluble solids and titratable acid of the sweet cherries. Fumigation with 2 or 6 mg × L -1 of thymol did not accelerate stem browning compared with the control, but fumigation with 10 mg × L -1 of thymol caused almost total stem browning. Fumigation with acetic acid showed no impact on discoloration of the stems. Conclusion. Thus, fumigation with acetic acid or thymol at low concentrations has a potential use for postharvest decay control without adverse effects on fruit quality. Résumé -Introduction. Les cerises sont susceptibles de pourrir après leur récolte. L'utilisation de fongicides synthétiques est à déconseiller lors des manutentions car ceux-ci peuvent laisser des résidus et présenter un risque pour la santé. L'utilisation de composés naturels peut pallier ces désagréments. La fumigation d'acides organiques à chaîne courte et d'huiles essentielles s'est révélée prometteuse pour contrôler les activités fongiques. L'étude fait état de leurs effets sur la conservation des cerises. Matériel et méthodes. Des cerises « Hedelfingen » (Prunus avium L.) ont été inoculées avec des conidies de Monilinia fructicola et Penicillium expansum, puis ont été traitées par fumigation avec trois doses de thymol ou d'acide acétique pendant 10 min avant d'être entreposées au froid. Résultats et discussion. Après 13 j à 10°C, les cerises traitées avec 10 mg × L -1 de thymol ont été significativement moins atteintes par la pourriture brune (12 %) que les cerises non traitées (21 %), mais le taux de cerises avec moisissure bleue n'a pas changé. La fumigation avec 6 ou 10 mg × L -1 d'acide acétique a diminué significativement le taux de moisissure bleue de 16 % à 2 %, mais n'a eu aucun effet sur la pourriture brune. Les divers traitements n'ont eu aucun effet sur la fermeté, le taux d'extrait sec et l'acidité titrable des cerises. La fumigation avec 2 o...

“…On the other hand, acetic acid (AA) in air at low concentrations is not flammable, explosive, or carcinogenic [12] and is very effective against molds such as P. expansum that cause storage decay [13]. Subsequent studies showed that AA fumigation would control postharvest decay caused by other pathogens such as Monilinia fructicola and Botrytis cinerea on apricots [14], cherries [15,16], citrus [16], grapes [17], peaches [14], nectarines [14] and strawberries [18]. Acetic acid vapor treatment for the control of postharvest decay has been reviewed [19] identifying additional uses in food processing and modified atmosphere packaging.…”

Fumigation with acetic acid vapor to control decay of stored apples.Abstract -Introduction. Apples are potentially subject to blue mold decay caused by Penicillium expansum if stored at 1°C for three or more months or if wounded during handling. Results from trials with apples contaminated with conidia of P. expansum and fumigated in small chambers with acetic acid (AA) vapor indicated that fruit could be sterilized to reduce decay without effect on fruit quality. The objective of this study was to determine if larger quantities of apples treated with AA vapor would have less decay after storage and/or wounding. It was also important to determine if fumigation would affect apple quality and aroma. Materials and methods. Apple cultivars were harvested at commercial maturity for use in AA fumigation trials. Apples artificially or naturally contaminated with conidia of P. expansum were fumigated with AA vapor in a 1 m 3 gas tight chamber at 10°C for 1 h to 24 h or dipped in 450 µg thiabendazole × L -1 solution. Fruit fumigated in standard wooden or plastic apple boxes, or small wooden bins were either wounded and evaluated for decay after a week at 20 °C or stored at 1 °C for three or more months and evaluated for decay. Then apple quality was assessed. Results. Apples naturally contaminated with Penicillium spp. that had been stored at 1 °C in air storage and treated with AA vapour had 50% less decay than the control fruit. In another experiment, AA fumigation was as effective as thiabendazole in reducing decay. AA fumigation reduced decay of fruit coming out of storage for apples stored for 3 months, and a second AA fumigation reduced infection of wounds on these same apples. AA fumigation before storage did not affect apple quality or vinegar aroma. Discussion. AA fumigation showed great potential for reducing decay in stored apples. It could be used as an organic alternative to synthetic fungicides for control of blue mold decay.

Les pommes sont potentiellement sujettes à la moisissure bleue provoquée par Penicillium expansum si elles sont stockées à 1 °C pendant 3 mois ou plus, ou si elles sont blessées pendant la manutention. Les résultats d'essais effectués avec des pommes contaminées par des conidies de P. expansum et fumigées dans un local restreint avec de la vapeur d'acide acétique (AA) ont montré que les fruits stérilisés pouvaient être moins détériorés, sans que leur qualité ne soit altérée. L'objectif de cette étude a été de déterminer s'il était possible de protéger de plus grandes quantités de pommes contre ces détériorations après stockage et/ou après blessures en les traitant à la vapeur de AA. Il s'agissait également de déterminer si la fumigation affectait la qualité et l'arôme des pommes traitées. Matériel et m...
