“…Sansone et al (2005) ferent when applied weekly, reduced the speed of disease progression, in magnitude similar to the treatment with fungicide, causing an increase in productivity, generating data similar to the treatment with fungicide (Piccinin et al, 2005). Zanardo et al (2010), in studies on the resistance of cucumber seedlings to C. orbiculare induced by fractions of S. cerevisiae extract concluded that this yeast contains fractions inducing resistance to this disease, where cotyledons treated with crude extracts of this yeast autoclaved by 4 or 10 h showed a significant reduction in the severity of the disease, with 86.0 and 82.2%, respectively.…”

This work aimed to evaluate the effect of the yeasts Candida albicans, Pichia guilliermondii, Rhodotorula glutinis, Saccharomyces cerevisiae and Zygoascus hellenicus in the control of anthracnose in cucumbers. The influence of volatile and non-volatile compounds on mycelial growth and the effect of cell suspension and culture filtrate on conidial germination were evaluated. In a greenhouse, yeasts were tested on cucumber cotyledons, one cotyledon being treated and the other not; afterwards both cotyledons were challenged with C. orbiculare. The severity of the disease in both cotyledons was assessed by determining biological control and resistance induction. The production of volatile compounds from the yeasts R. glutinis and C. albicans reduced the pathogen growth by 90.7 and 90.0%, respectively. The production of non-volatile compounds stimulated the pathogen development. Conidia germination was affected when exposed to cell suspension of all tested isolates, ranging from 43 to 75%. For the culture filtrate from Z. hellenicus, it reduced the conidia germination by 11.4%. In the in vivo test, on the treated cotyledon, the yeasts Z. hellenicus, R. glutinis and S. cerevisiae reduced the anthracnose severity by 52.5, 50.0 and 42.5%, respectively.

“…In a study conducted by Zanardo et al (2009), supernatant fractions obtained from the ethanolic precipitation of the aqueous gross extract of the Saccharimyces cerevisiae presented resistance inducting activity in cucumber plant cotyledons. The presence of these fractions, separated by ion exchange chromatography, demonstrates the method efficiency as to the process of purification molecules with eliciting activity for studies of resistance induction.…”

) was used as induction standard treatment. Ion exchange chromatography (IEC) and gel filtration chromatography (GFC) were applied to separate power eliciting fractions from five hundred female root knot nematodes (Meloidogyne javanica). The purification of elicitors, through IEC, resulted in sixty glicidic fractions and six glycoprotein ones. They were classified according to their nature, being twenty-six glicidic fractions and thirty-seven glycoprotein ones, with molecular masses ranging from 29.19 to 2,989.25 kDa. From the purified fractions, eight of them presented phaseolin inducing effect potential, whereas fifteen fractions presented gliceolin inducing effect. Chromatography proved to be efficient in purifying the eliciting compounds. Compounds having gliceolin and phaseolin suppressing characteristics were verified in the bioassays. For those fractions obtained through IEC and posteriorly submitted to GFC that did not induce phytoalexin, it is suggested that the molecules need to act jointly so there is eliciting effect and thus induce a defense response in the plant.

A melancia é uma cucurbitácea com grande importância socioeconômica, seu cultivo pode ser influenciado por doenças causadas por fungos habitantes do solo e que infectam sementes, como por exemplo, Fusarium sp. O uso contínuo de agrotóxicos no manejo de doenças pode causar o aparecimento de patógenos resistentes. Objetivou-se avaliar a eficiência de óleos essenciais e o biocontrole por Saccharomyces cerevisiae na cultura da melancia. Foram utilizados os óleos essenciais de capim limão, copaíba, erva-cidreira, erva-doce, gengibre, hortelã, manjericão e moringa na concentração de 1% foram diluídos em meio batata-dextrose-ágar. As variáveis estudadas foram: índice de velocidade de crescimento micelial, percentual de inibição do crescimento micelial, esporulação e percentual de inibição da esporulação. Para o controle com S. cerevisiae (fermento biológico Fleischmann®) foram utilizadas sementes de melancia cultivar Crimson Select Plus (Feltrin). As concentrações de levedura testadas foram: 0; 0,5; 1,0; 1,5 e 2,0 g L-1. Foram realizados os testes de sanidade; percentual de germinação; primeira contagem da germinação; índice de velocidade da germinação; sementes duras e mortas; plântulas anormais; matéria seca de raízes, parte aérea e plântulas e comprimento de raízes, parte aérea e plântula, tratadas com S. cerevisiae e óleos essenciais. Os tratamentos com erva-doce, hortelã e manjericão foram eficientes no controle de Fusarium sp. in vitro, apresentando efeito inibitório sobre o crescimento micelial e esporulação do patógeno. S. cerevisiae demonstrou não causar nocividade às sementes de melancia na concentração de 1,5 g L-1, tendo apresentado incremento de massa do sistema radicular e índice de velocidade da germinação.
