“…A atividade antifúngica de extratos de Momordica charantia L. sobre C. musae foi avaliada por Celoto et al (2011) os quais confirmaram que o extrato aquoso e hidroetanólico, obtidos de folhas e ramos, em meio sólido, proporcionaram 71 e 65% de inibição do crescimento micelial, respectivamente. Esse resultado corrobora com os encontrados neste trabalho, quanto ao método de aplicação em meio sólido (MS), que foi eficiente na inibição do crescimento micelial do C. musae, superando 90% de inibição.…”

A antracnose causada pelo fungo Colletotrichum musae é considerada das mais importantes moléstias em frutos de banana. O objetivo deste trabalho foi avaliar o efeito do óleo fixo de pinhão bravo no controle in vitro de C. musae, em diferentes concentrações e metodologias de aplicação. O fungo foi isolado de frutos de bananeira, cultivado em meio de cultura Batata-Dextrose-Ágar (B.D.A). O experimento conduzido em esquema fatorial com 2 fatores (3 métodos de aplicação e 3 concentrações + 2 testemunhas), com sete repetições. Os métodos de aplicação foram: incorporação do óleo ao meio de cultura fundente; distribuição do óleo no meio de cultura solidificado e distribuição do óleo em papel filtro, fixado na parte interna da tampa da placa de Petri. As concentrações do óleo utilizadas foram: 0,1; 1 e 10%. As testemunhas foram: testemunha absoluta (sem óleo e sem fungicida) e testemunha relativa (sem óleo e com fungicida). O óleo testado em todas as concentrações e métodos de aplicação foi diluído em Tween 80. Diariamente, por dez dias foi medido o crescimento radial em centímetros do micélio do fungo. Os dados foram analisados pelo teste de Tukey a 5% de probabilidade. Os tratamentos 1, 2, 5, 7, 8 e 11 proporcionaram maior inibição do crescimento micelial de C. musae e foram estatisticamente iguais entre si. O óleo fixo de pinhão bravo pode ser usado como medida alternativa de controle de C. musae em substituição aos pesticidas químicos.

“…Based on the methodologies and species implemented in the present study, no expressive effect was found with leaf extracts to control cotton ramulosis in in vitro assays (Figure 3), although some results have been found in the literature with others pathogens or crops at high concentration of extracts in in vitro assays. Celoto et al (2011) used leaf and branch extracts from Momordica charantia at 50% and found inhibition of 71% and 65% in mycelial growth, respectively, in a solid medium; the inhibitions in the liquid medium were 86% and 81%, respectively. Venturoso et al (2011) found that extracts of Syzygium aromaticum (L.) Merr.…”

Ramulosis (Colletotrichum gossypii South var. cephalosporioides Costa) is a fungal disease of cotton (Gossypium hirsutum L.) that causes damage to leaves, stems, and bolls by reducing fiber production; it can be controlled by chemical fungicides. Geraniol is a monoterpenoid produced by some aromatic plant species whose fungicidal properties have been widely reported. Geraniol synthase (GES; EC 3.1.7.11) is the precursor enzyme involved in the biosynthetic chain of geraniol. Geraniol synthase (ges) gene transcripts were prospected in 11 aromatic species with molecular and phytopathological tools to identify promising accessions for further use in in vitro and in vivo assays involving the control of cotton ramulosis. Mentha pulegium L. oil highly expressed ges and inhibited fungal growth at 1000 μL L-1 in an in vitro assay. Validation assays were carried out in two environments and M. pulegium at 2000 μL L-1 reduced the initial and final severity indices of the disease to 48% and 52%, respectively, in preventive treatments; in curative assays, indices were 44% and 54%, respectively. This indicates that it is a promising bioactive compound to control cotton ramulosis.

Bitter melon, bitter cucumber or bitter gourd are some of the names given to M. charantia. It belongs to the Cucurbitaceae family. 44 M. charantia is a vegetable with many culinary uses, especially in Asia and Africa, and is commonly cultivated in Africa, India, Malaysia, China and South America. 44,45 M.ABSTRACT Momordica charantia L. (bitter melon) is a plant belonging to the Cucurbitaceae family and is widely distributed in tropical and subtropical areas around the world, mainly in Asia, India, China and Brazil, where it is traditionally used as a medicinal plant, and the fruits of some varieties of M. charantia are consumed as food. Studies have determined that this plant contains a great diversity of bioactive compounds with therapeutic potential like charantin, α-momorcharin and MAP30, and highlighting its properties as antidiabetic, antiulcer, antioxidant, antimicrobial, anthelmintic, antihyperglycemic and anticancer. Review shows the complete botanical description of the plant (fruits, leaves, stem, etc.), the bioactive chemical compounds reported in the plant species, the antimicrobial activity of the extracts or fractions of M. charantia, emphasizing the antibacterial and antifungal activities, with respective values of MIC (Minimum Inhibitory Concentration) reported according to the methodology used in each study. The review seeks to update the phytochemical and pharmacological knowledge of M. charantia, which would be useful for researchers in their search for new chemical compounds of the plant, studies of its safety and efficacy, as well as the evaluation of its possible synergistic action in combination with other antimicrobials, in order to find new therapeutic alternatives against bacterial resistance.
