AB Broccoli (Brassica oleracea var. italica) is a crop of great agronomic and economic importance worldwide. Because itsedible parts are the inflorescences, large quantities of non-commercial biomass are produced each year in the field and inthe 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 diseasesproduced by the pathogens Botrytis cinerea, Alternaria alternata and Penicillium expansum. GSL extracts from organiccrop management reported a higher content of GSLs than conventional management. These extracts are not effective in thecontrol of A. alternata and P. expansum, possibly due to the absence of sinigrin. Furthermore, the extracts were ineffectivein the control of B. cinerea on table white grapes, possibly due to the non-climacteric fruit condition and an absence in theinduction of ethylene-mediated plant defenses. However, intact GSL extracts were effective in controlling B. cinerea onapple, while the addition of myrosinase enzyme caused effectiveness also on tomato and apple. Therefore, obtaining GSLextracts with biopesticidal capacity against B. cinerea in postharvest could be a circular economy strategy for broccoliagriculture and industry.
