“…Data in the literature about the IAA-producing ability of Trichoderma strains is limited. Chagas et al [41] investigated the IAA production of T. harzianum, T. pinnatum, T. longibrachiatum, and T. asperelloides, as well as two strains of T. virens, and recorded production values of 2.9-3.2 µg/mL. In the present study, the detected values were in a wider concentration range (1.349-8.248 µg/mL).…”

Research Highlights: A large scale effort to screen, characterize, and select Trichoderma strains with the potential to antagonize Armillaria species revealed promising candidates for field applications. Background and Objectives: Armillaria species are among the economically most relevant soilborne tree pathogens causing devastating root diseases worldwide. Biocontrol agents are environment-friendly alternatives to chemicals in restraining the spread of Armillaria in forest soils. Trichoderma species may efficiently employ diverse antagonistic mechanisms against fungal plant pathogens. The aim of this paper is to isolate indigenous Trichoderma strains from healthy and Armillaria-damaged forests, characterize them, screen their biocontrol properties, and test selected strains under field conditions. Materials and Methods: Armillaria and Trichoderma isolates were collected from soil samples of a damaged Hungarian oak and healthy Austrian spruce forests and identified to the species level. In vitro antagonism experiments were performed to determine the potential of the Trichoderma isolates to control Armillaria species. Selected biocontrol candidates were screened for extracellular enzyme production and plant growth-promoting traits. A field experiment was carried out by applying two selected Trichoderma strains on two-year-old European Turkey oak seedlings planted in a forest area heavily overtaken by the rhizomorphs of numerous Armillaria colonies. Results: Although A. cepistipes and A. ostoyae were found in the Austrian spruce forests, A. mellea and A. gallica clones dominated the Hungarian oak stand. A total of 64 Trichoderma isolates belonging to 14 species were recovered. Several Trichoderma strains exhibited in vitro antagonistic abilities towards Armillaria species and produced siderophores and indole-3-acetic acid. Oak seedlings treated with T. virens and T. atrobrunneum displayed better survival under harsh soil conditions than the untreated controls. Conclusions: Selected native Trichoderma strains, associated with Armillaria rhizomorphs, which may also have plant growth promoting properties, are potential antagonists of Armillaria spp., and such abilities can be exploited in the biological control of Armillaria root rot.

Fungos do gênero Trichoderma são uns dos principais micro-organismos de importância para o aumento do crescimento vegetal. Desta forma, objetivou-se com este trabalho avaliar a eficiência da inoculação de Trichoderma asperellum UFT 201, como promotores de crescimento vegetal nas culturas da soja, feijão caupi, arroz e milho, em casa de vegetação. As características de biomassa das culturas foram determinadas através da massa seca da parte aérea, massa seca da raiz e massa seca total, bem como a eficiência relativa. Nas diferentes culturas estudadas, a inoculação de T. asperellum UFT 201 foi superior para as características de biomassa, mostrando o potencial como promotor de crescimento, com aumento acima de 60% em relação à testemunha, para todas as culturas. Os resultados demonstram a capacidade do inoculante Trichoderma asperellum UFT 201, em promover o crescimento inicial de plantas, como observado para as culturas estudadas.

Filamentous fungi of the genus Trichoderma are known for their activity as plant growth promoters. The objective of this work was to evaluate the efficiency of the Trichoderma asperellum UFT 201 strain as a plant growth promoter in soybean. The ability of phosphate solubilization, indole acetic acid synthesis and the effect on soybean plant growth under greenhouse conditions were evaluated in four experiments. In vitro and in vivo analyzes were performed. Plant biomass characteristics such as shoot dry mass (SDM), root dry mass (RDM) and total dry mass (TDM) were evaluated. T. asperellum UFT 201 showed a significantly higher concentration (p <0.05) with a phosphate solubilization capacity of 67.8% higher than the positive control treatment (Trichoderma harzianum). The production of indole acetic acid (IAA) by T. asperellum UFT 201 was 26.7% higher than the positive control. The effect on the biomass treated by T. asperellum UFT 201 was higher (p <0.05) than the positive and absolute controls. Thus, inoculation by T. asperellum UFT 201 showed high efficiency as a growth promoter in soybean.
