In the search for alternatives to the use of synthetic fungicides, aqueous spice extracts were evaluated for their effects on the mycelial growth of various spoilage pathogens and their ability to control potato dry rot and carrot cavity spot in vivo. Results showed that cinnamon, ginger and nutmeg significantly inhibited the mycelial growth of Aspergillus niger (Ascomycota), Fusarium sambucinum (Ascomycota), Pythium sulcatum (Oomycota) or Rhizopus stolonifer (Zygomycota), whereas horseradish extract did not lead to the inhibition of any microorganism at the tested concentration. Among the most effective extracts, 0.05 g mL‑1 of cinnamon extract completely inhibited A. niger and P. sulcatum, and 0.10 g mL‑1 of cinnamon extract completely inhibited F. sambucinum. A concentration of 0.05 g mL‑1 of ginger extract also caused 100% inhibition of P. sulcatum. In vivo, cinnamon extract significantly reduced lesions of potato dry rot and carrot cavity spot, and ginger extract reduced lesions of carrot cavity spot. These results indicate that aqueous cinnamon and ginger extracts could provide an alternative to the use of synthetic fungicides to control these pathogens.Dans la recherche de moyens de remplacement à l'utilisation de fongicides de synthèse, des extraits aqueux d’épices ont été évalués pour leurs effets sur la croissance mycélienne de plusieurs agents pathogènes de conservation et pour leur efficacité in vivo de répression de la pourriture sèche de la pomme de terre et de la maladie de la tache de la carotte. Les travaux réalisés montrent que les extraits de cannelle, de gingembre et de muscade inhibent significativement la croissance mycélienne des hyphomycètes Aspergillus niger et Fusarium sambucinum, de l’oomycète Pythium sulcatum, ou du zygomycète Rhizopus stolonifer, alors que l’extrait de raifort n’a causé aucune inhibition à la concentration testée. Parmi les extraits les plus efficaces, 0,05 g mL‑1 d’extrait de cannelle a complètement inhibé A. niger et P. sulcatum, alors que 0,10 g mL‑1 d’extrait de cannelle a complètement inhibé F. sambucinum. Une concentration de 0,05 g mL‑1 de gingembre a également causé une inhibition de 100 % de P. sulcatum. Des essais in vivo ont montré que l’extrait de cannelle réduisait significativement les lésions de la pourriture sèche et de la maladie de la tache et que l’extrait de gingembre réduisait les lésions de la maladie de la tache. Cette étude suggère la possibilité d’utiliser des extraits aqueux de cannelle ou de gingembre comme produits de remplacement aux fongicides de synthèse pour la répression de certains agents pathogènes

Mediterranean Wild Edible Plants

All countries overlooking the Mediterranean basin possess a varied germplasm of wild edible herbaceous species, with Turkey, Spain, and Italy having the richest floras (Aedo et al. 2013). According to unpublished data gathered by one of us (VV Bianco), Italy probably has one of the highest numbers of wild herbs utilizable as food and condiment. Studies on botanical, agronomical, gastronomic, and nutritional aspects of wild edible herbaceous plants existing in Italy have been undertaken by Bianco since 1964. In the first published work (Bianco 1969), 113 species were reported. In the successive study (Bianco 1989), 360 taxa belonging to 66 families and 230 genera were listed. Afterwards, the results released by Bianco and Machakova (2002) showed that the number of taxa has reached 808, belonging to 91 families and 403 genera. Nowadays, according to the latest data of Bianco, the taxa utilizable as food and condiment herbs may reach 1078, corresponding to 14 % of the total number of taxa surveyed for the Italian vascular flora (Conti et al. 2005). They belong to 96 families, the most important being the following: Asteraceae (18.7 %), Brassicaceae (7.7 %), Lamiaceae (7.1 %), Apiaceae (6.6 %), Fabaceae (5.5 %), Polygonaceae (3.8 %), Chenopodiaceae (3.2 %), Boraginaceae (2.5 %), Alliaceae (2.4 %), and Malvaceae (2.0 %), and 451 genera, where the most represented are the following: Allium (26), Rumex (21), Lathyrus (15), Chenopodium (14), Crepis (13), Vicia (12), Amaranthus, Malva, and Plantago (9). Leaves are the most used organ in culinary preparation (about 70 % of the taxa), followed by tender stems (45 %), flowers (18 %), and roots (16 %); fruits, rhizomes, bulbs,

“…They are also the main cause for alterations in the appearance, flavor and reduction of nutritional values of food products (Magro, Carolino, Bastos, & Mexia, 2008). Synthetic fungicides and preservatives usually employed to treat phytopathogenic fungi or to inhibit food spoilage are toxic and harmful to environment and health.…”
