ADIRANO-ANAYA, María de Lourdes et al. Effect of alcoholic extracts of garlic (Allium sativum) and clove (Syzygium aromaticum) on the development of Mycosphaerella fijiensis Morelet. Rev. mex. fitopatol [online]. 2018, vol.36, n.3, pp.379-393. ISSN 2007-8080.  https://doi.org/10.18781/r.mex.fit.1805-2.

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.
