“…Ribeiro & Bedendo (1999) observed a reduction of 67.57% in mycelial growth working with A. sativum extract at 1%. Rozwalka et al (2008) observed that C. gloeosporioides can be affected by aqueous extracts of Rosmarinus officinalis L., Zingiber officinale Rosc., Chamomila recutita L. and S. aromaticum at a concentration of 10% with 50.57%, 64.37%, 73.56% and 100% of mycelial growth inhibition.…”

Generally, the medicinal plants have antifungal substances that can be used for the plant protection against phytopathogens. The objective of this study was to know the efficiency of aqueous extracts from medicinal plants against the major etiological agents of coffee tree. The aqueous extracts used were extracted from bulbs of Allium sativum, leaves of Vernonia polysphaera, Cymbopogon citratus, Cymbopogon nardus, Cordia verbenacea, Eucalyptus citriodora, Ricinus communis, Azadirachta indica, Piper hispidinervum and flower buds of Syzygium aromaticum. The etiological agents considered for this study were Cercospora coffeicola, Colletotrichum gloeosporioides, Fusarium oxysporum, Phoma tarda, Rhizoctonia solani and Hemileia vastatrix. The screening for harmful extracts was done based on mycelial growth and conidial germination inhibition. All experiments performed were in vitro conditions. The inhibition of mycelial growth was performed mixing the extracts with the PDA. This mixture was poured in Petri dishes. On the center of the dishes was added one PDA disc with mycelium. It was incubated in a chamber set to 25ºC. The evaluation was done daily by measuring the mycelial growth. The germination assessment was also performed with Petri dishes containing agar-water medium at 2%. These were incubated at 25ºC for 24 hours. After this period the interruption of germination was performed using lactoglycerol. The experiments were conducted in a completely randomized design. The most effective plant extracts against the micelial growth and conidial germination were V. polysphaera, S. aromaticum and A. sativum. Keywords: Phoma tarda, Cercospora coffeicola, Colletotrichum gloeosporioides, Hemileia vastatrix, Phytopathology.RESUMO: Atividade antifúngica utilizando extratos de plantas medicinais contra fitopatógenos do cafeeiro.

Os extratos aquosos utilizados foram extraídos de bulbos de Allium sativum, folhas de Vernonia polysphaera, Cymbopogon citratus, Cymbopogon nardus, Cordia verbenacea, Eucalyptus citriodora, Ricinus communis, Azadirachta indica, Piper hispidinervum e botões florais de Syzygium aromaticum. Os agentes etiológicos considerados neste estudo foram Cercospora coffeicola, Colletotrichum gloeosporioides, Fusarium oxysporum, Phoma tarda, Rhizoctonia solani e Hemileia vastatrix. A triagem dos extratos foi realizada com base no crescimento micelial e na inibição da germinação de conídios. Todos os experimentos foram realizados em condições in vitro. A inibição do crescimento micelial foi realizada misturandose os extratos com PDA. Esta mistura foi vertida em placas de Petri. No centro das placas foi adicionado um disco de PDA com micélio. Incubou-se em câmara programada para 25°C. A avaliação foi feita diariamente através d...

“…camara, belonging to the Verbenaceae family, exhibits antimicrobial activity (DEENA;THOPPIL, 2000), efficacy against termite workers (VERMA; VERMA, 2006) and has a nematostatic effect on the phytonematode Meloidogyne incognita (DIAS et al, 2000). T. minuta, from the Asteraceae family, has fungitoxic effects (ROZWALKA et al, 2008), activity against Anopheles stephensi larvae (HADJIAKHOONDI et al, 2005), antibacterial activity (SOUZA et al, 2000) and effect on H. contortus egg and larvae (MACEDO et al, 2012). A. zerumbet, from the Zingiberaceae family, exhibits antioxidant (ELZAAWELY et al, 2007), antibacterial and antifungal activities (VICTÓRIO et al, 2009).…”

In vitro effects of AbstractPhytotherapy can be an alternative for the control of gastrointestinal parasites of small ruminants. This study evaluated the efficacy of Alpinia zerumbet, Coriandrum sativum, Tagetes minuta and Lantana camara essential oils by two in vitro assays on Haemonchus contortus, an egg hatch test (EHT) and larval development test (LDT). No effect was observed for L. camara in the EHT. A. zerumbet, C. sativum and T. minuta essential oils exhibited a dose-dependent effect in the EHT, inhibiting 81.2, 99 and 98.1% of H. contortus larvae hatching, respectively, at a concentration of 2.5 mg mL -1 . The effective concentration to inhibit 50% (EC50) of egg hatching was 0.94, 0.63 and 0.53 mg mL -1 for A. zerumbet, C. sativum and T. minuta essential oils, respectively. In LDT, L. camara, A. zerumbet, C. sativum and T. minuta at concentration of 10 mg mL -1 inhibited 54.9, 94.2, 97.8 and 99.5% of H. contortus larval development, presenting EC50 values of 6.32, 3.88, 2.89 and 1.67 mg mL -1 , respectively. Based on the promising results presented in this in vitro model, it may be possible use of these essential oils to control gastrointestinal nematodes. However, their anthelmintic activity should be confirmed in vivo.Keywords: Phytotherapy, anthelmintic, gastrointestinal nematodes. ResumoFitoterapia pode ser uma alternativa para o controle de parasitas gastrintestinais de pequenos ruminantes. Este estudo avaliou a eficácia dos óleos essenciais de Alpinia zerumbet, Coriandrum sativum, Tagetes minuta e Lantana camara sobre Haemonchus contortus através de dois testes in vitro, teste de eclosão dos ovos (TEO) e teste de desenvolvimento larval (TDL). Nenhum efeito foi observado para L. camara no TEO. Os óleos essenciais de A. zerumbet, C. sativum e T. minuta exibiram um efeito dose dependente no TEO inibindo a eclosão das larvas de H. contortus em 81,2, 99 e 98,1%, respectivamente, na concentração de 2,5 mg mL -1 . A concentração efetiva para inibir 50% (CE50) da eclosão dos ovos foi de 0,94, 0,63 e 0,53 mg mL -1 para os óleos essenciais de A. zerumbet, C. sativum e T. minuta, respectivamente. No TDL, 10 mg mL -1 de L. camara, A. zerumbet, C. sativum e T. minuta inibiram em 54,9, 94,2, 97,8 e 99,5% do desenvolvimento larvar, apresentando valores de CE50 de 6,32, 3,88, 2,89 e 1,67 mg mL -1 , respectivamente. Com base nos resultados promissores apresentados neste modelo in vitro, pode ser possível a utilização destes óleos essenciais para controlar os nematoides gastrintestinais. No entanto, a sua atividade anti-helmíntica deve ser confirmada in vivo.Palavras-chave: Fitoterapia, anti-helmínticos, nematoides gastrintestinais.

“…Em laboratório, foi avaliado o efeito fungitóxico de algumas plantas medicinais e aromáticas, entre elas, a camomila, acreditando que poderia haver alguma ação contra os fungos Glomerella cingulata e Colletotrichum gloeosporioides, causadora da antracnose em goiaba (Psidium guajava L.). Constatou-se que a camomila, preparada em decocto, deteve grande controle biológico de C. gloeosporioides, indicando sua aplicação como controle alternativo contra antracnose (ROZWALKA, 2008).…”
