Broccoli (Brassica oleracea var. italica) biomass as a resource for obtaining glucosinolate extracts to control postharvest fungal diseases Eugui, Daniel Fernández San Millán, Alicia Velasco, Pablo Veramendi, Jon Rodríguez, Víctor M. Poveda Arias, Jorge Broccoli (Brassica oleracea var. italica) is a crop of great agronomic and economic importance worldwide. Because its edible parts are the inflorescences, large quantities of non-commercial biomass are produced each year in the field and in the food industry. In order to develop a circular economy around the broccoli crop, the present work develops glucosinolates (GSL) extracts with antimicrobial capacity for postharvest use in tomato, apple and table white grape against fungal diseases produced by the pathogens Botrytis cinerea, Alternaria alternata and Penicillium expansum. GSL extracts from organic crop management reported a higher content of GSLs than conventional management. These extracts are not effective in the control of A. alternata and P. expansum, possibly due to the absence of sinigrin. Furthermore, the extracts were ineffective in the control of B. cinerea on table white grapes, possibly due to the non-climacteric fruit condition and an absence in the induction of ethylene-mediated plant defenses. However, intact GSL extracts were effective in controlling B. cinerea on apple, while the addition of myrosinase enzyme caused effectiveness also on tomato and apple. Therefore, obtaining GSL extracts with biopesticidal capacity against B. cinerea in postharvest could be a circular economy strategy for broccoli agriculture and industry. 2025-06-12T09:30:08Z 2025-06-12T09:30:08Z 2025-06-12T09:30:08Z 2025 info:eu-repo/semantics/article Journal of Plant Diseases and Protection, 2025, vol.132, n. 3 1861-3829 https://uvadoc.uva.es/handle/10324/75948 10.1007/s41348-025-01099-w 3 Journal of Plant Diseases and Protection 132 1861-3837 eng https://link.springer.com/article/10.1007/s41348-025-01099-w info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/4.0/ © 2025 The Author(s) Atribución 4.0 Internacional Springer
