“…After 7 days of incubation at 25 • C in the dark, mycelial growth inhibition for each treatment and concentration was determined according to the formula: ((d c −d t )/d c )×100, where d c and d t are the average diameters of the control and treated fungal colonies, respectively [16].…”

Phytophthora cinnamomi is responsible for radical rot in a wide range of hosts, resulting in large economic and ecological losses worldwide. In Spain, it is responsible for diseases such as the oak decline or the chestnut blight. In this study, different polyphenol-stevioside inclusion compounds dispersed in a hydroalcoholic solution of chitosan oligomers have been investigated, with a view to their application as natural bioactive complexes to replace conventional systemic fungicides against this fungus. The polyphenols tested in vitro were curcumin, ferulic acid, gallic acid and silymarin. Three concentrations (125, 250 and 500 µg·mL −1 ) were assayed, with and without silver nanoparticles (AgNPs), and notable differences were found in the inhibition of mycelium growth, with EC 50 and EC 90 values ranging from 171 to 373.6 µg·mL −1 , and from 446.2 to 963.7 µg·mL −1 , respectively. The results obtained showed that the addition of AgNPs, despite their antimicrobial activity, did not always lead to synergies. In the case of P. cinnamomi, an unexpected antagonistic behavior was found for two of the polyphenols (curcumin and silymarin), while an additive behavior for ferulic acid and a synergistic behavior for gallic acid were attained. In view of their inhibitory power, the preparations based on ferulic acid with AgNPs and on silymarin without AgNPs are proposed for applications in crop and forests protection against P. cinnamomi.

“…Las hierbas y las especias (plantas aromáticas) son las plantas que con mayor énfasis se han estudiado. De dichas plantas, tanto los aceites esenciales como los extractos obtenidos con diferentes disolventes y procesos, han mostrado efecto antifúngico contra fitopatógenos de los géneros: Colletotrichum Radwan et al, 2014;Garcia, 2011), Aspergillus (Tijjani et al, 2014;Askun et al, 2008), Phoma (Touba et al, 2012), Fusarium (Taskeen-Un- , Penicillium Ikeura et al, 2011), Botrytis (Daniel et al, 2015;Sesan et al, 2015) y Alternaria (Nashwa y Abo-Elyousr, 2012).

Resumen. La Sigatoka Negra es la enfermedad más destructiva del área foliar de plátanos y bananos. La incrementada resistencia del patógeno, y la contaminación provocada por los fungicidas químicos, han guiado a la búsqueda de alternativas para su control. El objetivo del trabajo fue determinar el efecto de la combinación de los extractos de ajo (Allium sativum) y clavo (Syzygium aromaticum) en Abstract. Black Sigatoka is the most destructive disease of the leaves of bananas. The increased resistance of the pathogen and the contamination caused by chemical fungicides have guided the search for control alternatives. The objective of the work was to determine the effect of the combination of extracts of garlic (Allium sativum) and clove (Syzygium aromaticum) in the development of Mycosphaerella fijiensis. The phytopathogen was grown in potato-dextrose-agar (PDA) media added with different concentrations of extracts. A factorial design of two factors at four levels was established. At higher concentration of garlic extract, less capacity to inhibit M. fijiensis colony. In contrast, the clove extract showed greater inhibition capacity at the higher concentration. The greatest inhibition of the growth, 39.6%, was with the mixture of 150 mg of garlic extract·ml -1 and 36 mg of clove extract·ml -1 . Effect of alcoholic extracts of garlic (Allium
