EXTRACTS OF CINNAMON (Cinnamomum cassia) AND MINT (Mentha arvensis) FOR THE FUNGI CONTROL OF Sclerotinia sclerotiorum

Abstract

Studies regarding vegetal extracts and essential oils from native plants have demonstrated efficiency in controlling phytopathogens of fungitoxic action, hampering the development of phytopathogenic fungi. This study aims to determine the fungicide effect of vegetal extracts during the mycelial growth of the fungus Sclerotinia sclerotiorum (Lib.) de Bary. The experiment was conducted in the phytosanitary laboratory of the UEMS in the unit of Cassilândia-MS, Brazil. A completely randomized design was used with a factorial scheme 4 x 5, comprising leaves, bark, and branches of cinnamon and mint leaves in the concentrations of 0, 2.5, 5.0, 10, and 20%, with six repetitions per treatment. The evaluations were made 24, 48, and 96 hours after the transplant, obtaining the diametrically opposite means with a caliper to determine the measures. The results indicate a higher inhibitory efficiency against fungi development using extracts of mint leaves and cinnamon leaves and branches.
