“…In order to evaluate the antagonistic action of Trichoderma in the control of Fusarium solani, it was observed that 21.74% of the Trichoderma isolates inhibited the growth of the pathogen and 52% had no inhibitory effect against Fusarium in the culture pairing test (LOUZADA et al, 2009).…”

The increase in flower cultivation in recent years has been reflecting the higher incidence of soil pathogens that can cause serious problems. This study aimed to evaluate the biological control of Fusarium wilt in gerbera with Trichoderma asperellum. The evaluated treatments were: T1) Control, only sterile substrate; T2) Substrate + Fusarium oxysporum; T3) Substrate + Fusarium oxysporum + Trichoderma asperellum; and T4) Substrate + Trichoderma asperellum. For this, the pathogen was isolated from gerbera with disease symptoms and, subsequently, it was identified according to morphological characters. Furthermore, the degree of antagonism of T. asperellum against F. oxysporum was evaluated through the culture pairing test. For greenhouse evaluations, commercial autoclaved substrate was used and infested with corn grains infected by the pathogen. Morphological identification confirmed the pathogen species as Fusarium oxysporum. In the culture pairing test, it was found that T. asperellum did not present a high degree of antagonism. The plants cultivated on substrate infested by the pathogen had no visible symptoms of wilt, but the substrate infestation with the pathogen provided lower values of fresh and dry mass of shoots and roots. The treatment with T. asperellum obtained higher values of fresh and dry mass of both shoots and roots, and also more vigorous inflorescences in relation to the plants treated with the pathogen

“…as a plant growth promoters and numerous researches have been conducted because these fungi produce antimicrobial substances which ensure a wide spectrum of activity against various plant pathogens. Moreover, some strains of Trichoderma promote plant growth by increasing the availability of nutrients and production of growth hormones Louzada et al, 2009). The root colonization often increases the development, crop yield, resistance to abiotic stresses and improves nutrient use (Rubio et al, 2014).…”

A B S T R A C TThe rhizosphere contains many microorganisms that can promote plant growth and protect the root system against infection by pathogens. Fungi of Trichoderma sp. are included in this group. The aim of this study was to evaluate efficiency of the inoculation of Trichoderma in agronomic performance of cowpea under field conditions, in the savanna in Gurupi, Tocantins, in harvests 2013/2014 to 2014/2015. The treatments consisted in seed treatment, with and without inoculation with Trichoderma asperellum UFT 201 with minimum concentration of viable conidia of 2x10 9 L -1 , at a dose of 20 g kg -1 of seed. Biomass evaluations were made on efficiency, initial and final stands and survival in the use of Trichoderma in the stand maintaining and productivity. The results indicated that the ability of bio-protection and plant growth promotion were of great importance for the biomass production, the stand maintaining and cowpea productivity. In both harvests, survival was superior in the plants treated with Trichoderma, 23.0 and 13.2%, respectively, and yields were 9.5% higher compared to control for the two harvests. In general, the inoculation of Trichoderma provided the best results in the biomass variables analyzed for the two crops with higher productivity.Keywords: biomass, productivity, Trichoderma, Vigna unguiculata. R E S U M OA rizosfera contém muitos microorganismos que podem promover o crescimento vegetal e proteger o sistema radicular de infeções por agentes patogénicos. Neste grupo incluem-se fungos de Trichoderma sp. O objetivo deste estudo foi avaliar a eficiência da inoculação de Trichoderma na performance agronómica de feijão-frade em condições de campo, na savana em Gurupi, Tocantins, nas campanhas de 2013/2014 a 2014/2015. Os tratamentos consistiram sementes inoculadas (ou não) com Trichoderma asperellum UFT 201 com uma concentração de conídios viáveis mínima de 2x10 9 L -1 , numa dose de 20 g kg -1 de semente. Foram efetuadas avaliações de biomassa em termos de eficiência, populações iniciais e finais e sobrevivência de Trichoderma, e na manutenção e produtividade da cultura. Os resultados indicam que a capacidade de bioproteção e promoção do crescimento vegetal foram de grande importância para a produção de biomassa, a manutenção da cultura e a produtividade de feijão-frade. E mambas as campanhas a sobrevivência foi superior nas plantas tratadas comTrichoderma, 23,0 e 13,2% respetivamente, e as produtividades foram 9,5% superiores ao controlo em ambas as campanhas. Em termos globais, a inoculação com Trichoderma providenciou os melhores resultados nas diversas variáveis ilustradoras de biomasse para as duas campanhas, conduzindo a uma maior produtividade.

“…Aproximadamente 80% dos fungos endofíticos produzem compostos biologicamente ativos, como antibióticos, fungicidas e herbicidas [2]. O controle biológico de fitopatógenos tem se apresentado como uma forma promissora e viável, por meio do uso de micro-organismos como agentes protetores de plantas cultivadas [5,6,7]. Desde o início da domesticação das plantas pelos humanos, há 10.000 anos, fitopatógenos têm causado perdas nos campos cultivados e redução do valor estético e do tempo de armazenamento da colheita [8].…”

“…Os testes in vitro apresentam a vantagem de permitir o conhecimento dos mecanismos de ação envolvidos (ex: antibiose e hiperparasitismo) e facilitar a observação das interações entre o antagonista e o fitopatógeno [6,11].…”
