Potencialidade de fungicidas biológicos no controle de requeima do tomateiro

Abstract: Potential of biologic fungicide in controlling late blight of tomatoThis study aimed to compare the efficiency of chemicals and biological agents in the alternative control of P. infestans in tomato hybrid Silvety. The experiment was carried out in the experimental area of the State University of Southwest Bahia, Brazil in a randomized block design with five treatments and four replications. The experimental unit consisted of 12 plants. The treatments (T) were: T1) nonsprayed check; T2) Trichoderma harzianum; … Show more

“…These compounds can interfere with the metabolic activities of other microorganisms by inhibiting growth and sporulation, reducing spore germination, and weakening the sclerotia. Many Trichoderma species are strong producers of cellulases, chitinases and β-1,3-glucanases, proteases, and lipases, which act in concert with metabolites in the mycoparasitic activity of these fungi [31,[39][40][41][42][43][44][45].…”

“…A partir do processo de produção de antibiótico pelo biocontrolador, a antibiose se faz mais atuante e mesmo que esteja em concentrações mínimas, elas podem causar interferências metabólicas e fisiológicas paralisando o crescimento, redução e inibição da produção de esporos, degradação por hidrólise e distorção das hifas (Bettiol & Wagner Bettiol, 1991;Carvalho Filho, 2013;Claydon et al, 1987;Dias, 2011;Souza, 2013).…”

“…Desta forma, o biocontrolador precisa sintetizar lipases, proteases, quitinases, celulase, glucanases etc. Estas enzimas precisam ser produzidas em quantidades necessárias para interromper o processo biológico dos fitopatógenos e garantir a penetração, antibiose e hiperparasitismo do biocontrolador (Bomfim et al, 2010;Harman et al, 2004;Melo, 1991;Silva, et al, 2020aSilva, et al, , 2020bSouza, 2013).…”

“…Encontra-se entre as dez espécies de hortaliças mais cultivadas no Brasil [4]. O tomate possui fins diversificados como in natura, processado como suco, pasta, molho ou vendido seco para consumo [5]. Um problema encontrado na produção de sementes de tomate é aliar a utilização de espécies adaptadas com a produção de sementes de alta qualidade, para atribuir à produção sementes com rápida germinação produzindo plantas vigorosas e sadias [6].…”
