“…Many factors can interfere with the efficiency of phosphate-solubilizing microorganisms, such as the preparation of the inoculant, the form of application to the soil and the place where it is applied 51 . In addition, Garcia Lopes (2017) demonstrated that the type of soil may be related to the activity of microorganisms 68 . The concentration of P applied to the different soil was not affected, but its efficiency was affected by the physical and chemical properties of the soil 69,70 .…”

“…The efficiency of microorganisms that assist in the availability of P in the soil is correlated with their ability both to promote plant growth in other ways and to control phytopathogens that are present in the soil. Biological control agents with resources to make nutrients available to plants are increasingly being targeted by studies 66,68 . In this context, the genus Trichoderma comprises fungi of great importance in agriculture; these fungi are known as disease control agents for various pathogens and act as growth promoters of various crop species 28,42,71,72 . conclusions In this study, Trichoderma isolated from soils of the Amazon rainforest demonstrated the potential for phosphate solubilization and increased soybean plant growth, highlighting the importance of the Amazon biome as a source of novel microbial stains with biotechnological importance.…”

Acidic soils rapidly retain applied phosphorus fertilizers and consequently present low availability of this nutrient to plants. the use of phosphate-solubilizing microorganisms to help plant phosphorus (P) absorption is a promising sustainable strategy for managing P deficiencies in agricultural soils. Trichoderma strains have been one of the most studied filamentous fungi for improving the production and development of several crop species mainly due to their capability for symbiotic associations and their ability to control soil-borne plant diseases. Thus, this work sought to bioprospect Trichoderma strains from the Amazon rainforest capable of solubilizing/mineralizing soil phosphate and promoting soybean growth. Soybean plants inoculated with selected Trichoderma strains were cultivated in soil under greenhouse conditions and under a gradient of rock phosphate and triple superphosphate. As a result, 19.5% of the isolated Trichoderma strains were able to solubilize phosphate. In addition, those strains produced different organic acids during the solubilization process. Trichoderma spp. strains showed positive responses in the promotion of soybean growth-from 2.1% to 41.1%-as well as in the efficiency of P uptake-up to 141%. These results reveal the potential of Trichoderma spp. from the Amazon biome as promising biofertilizer agents.The high demand for fertilizers used in Brazilian agriculture is a result of the growing population, which necessitates an increase in food production 1 . Brazil is the second-largest supplier of food and agricultural products and expected to be the leading producer of food to meet global demand in the near future 2 . Thus, applications of fertilizer are a routine activity in agricultural production as an attempt to promote crop growth to increase productivity. The requirement of fertilizers in the field results in the accumulation of those inputs in soils and water and, therefore, environmental pollution, causing problems to human and animal health 1,3 . In the future, Brazilian agriculture has to identify alternatives to reduce its dependence on chemical fertilizers while at the same time functioning in a lucrative and more sustainable way 4 .A range of nutrients is important for plant growth 5 , but the ones that limit agricultural production the most are nitrogen and phosphorus, which are important in the initial development of the plant 6,7 . Nitrogen fertilization in Brazil has decreased significantly with use of symbiotic associations with nitrogen-fixing bacteria 8,9 . However, Brazilian agriculture continues to depend on chemical phosphate fertilization 4 . The role of P in the plant is associated with three essential biochemical processes: energy production, respiration, and photosynthesis. P is also involved in enzymatic processes and is a component of nucleic acids and cell membranes [10][11][12][13] . Phosphorus is generally found in the lowest concentration in the soil, 0.01%, compared to 0.14% of nitrogen, mainly in tropical and subtropical regions 14,15 . Although ...

“…The application of Trichoderma strains increases plant photosynthetic ability, up-regulating both light harvesting components and Calvin cycle (dark reaction) components [24]. Trichoderma and its secondary metabolites also enhance the uptake and use efficiency of macronutrients, such as nitrogen [3,16] or phosphorus [25,26], and oligo/micro-nutrients, such as iron [8,27,28] or zinc [29].…”

Effects of Foliar Treatment with a Trichoderma Plant Biostimulant Consortium on Passiflora caerulea L. Yield and Quality

et al. 2020

The influence of spore concentration on the ability of a Trichoderma consortium to colonize the Passiflora caerulea phyllosphere was evaluated by determining the effects of foliar treatments with two spore concentrations, in two repeated treatments, on the morphological, physiological, and ultrastructural characteristics, and on the yield and quality of P. caerulea. The studied crop quality features were related to its nutraceutical use: the accumulation of polyphenols and flavonoids, antioxidant activity, and effects on mouse fibroblast L929 cells. The Trichoderma consortium consisted of two strains, T. asperellum T36b and T. harzianum Td50b, and the concentrations used were 106 colony forming units (cfu)/mL and 108 cfu/mL. As a reference treatment, a commercial product that was based on herbs and algal extracts was used. As compared to the negative control, the treatment with the Trichoderma consortium at 108 cfu/mL concentration determines the accumulation of higher level of polyphenols and flavonoids and increased antioxidant activity. This enhancement of P. caerulea quality characteristics after treatment with the higher concentration of Trichoderma consortium was associated with larger leaves, increased number and size of chloroplasts, improved plant physiology characteristics, and an increased yield. The treatment with high concentration of Trichoderma consortium spores promotes phyllosphere colonization and benefits both crop yield and quality.

“…Dentre os microrganismos benéficos, fungo do gênero Trichoderma tem sido um dos mais estudados para melhorar a produção e desenvolvimento de diversas culturas (CHAGAS et al, 2017;GARCÍA-LÓPEZ;DELGADO, 2016;THONAR et al, 2017) principalmente, pela sua capacidade de colonização radicular, formando associação simbiótica com as plantas . E ainda, podem suprir as necessidades nutricionais da planta, por exemplo, pela solubilização de fosfato (ASERI; JAIN; TARAFDAR, 2015; BORGES CHAGAS et al, 2015).…”

“…No geral, a atividade microbiana no controle foi menor do que nos tratamentos com inoculação dos isolados de Trichoderma, o que sugere a presença do fungo na rizosfera das plantas da soja ou alteração na atividade da comunidade microbiana, devido a presença do inóculo. Os agentes de controle biológico com recursos para disponibilizar nutrientes às plantas estão sendo cada vez mais alvo de estudosGARCÍA-LÓPEZ et al, 2018). Neste contexto, o gênero Trichoderma compreende fungos de grande importância na agricultura, estes fungos são conhecidos como agentes de controle de doenças para vários patógenos e atuam como promotores de crescimento de várias espécies de culturasSHARMA et al, 2013;ZHANG et al, 2019;ZHOU et al, 2018).…”
