“…Therefore, there are several formulations of biofungicides containing Trichoderma that can be used for seed treatment, applied directly to the soil, or via foliar application (Rodrigues et al 2023). It is important to remember that Trichoderma can also promote plant growth and enhance the productivity of various crops such as soybean (Senger et al 2022), cotton (Silva et al 2022), sugarcane (Scudeletti et al 2021), and rice (Cortés-Rojas et al 2021). These fungi can improve root architecture and other plant organs through the production of phytohormones, such as indole-3-acetic acid (IAA) (Machado-Rosa et al 2023).…”

“…Trichoderma can also assist in meeting nutritional needs of plants by solubilizing minerals from chemical fertilizers or the soil itself, such as phosphorus (Paul and Rakshit 2021). Previous studies have also shown that Trichoderma can accelerate seed germination and enhance the early responses and establishment of soybean seedlings in greenhouse and eld conditions (Senger et al 2022).…”

“…Rojas et al 2021;Senger et al 2022;Silva et al 2022). In our study, we isolated 66 native Trichoderma isolates from the rhizosphere of soybean plants cultivated in the state of Mato Grosso do Sul, Brazil.Similar previous research has successfully identi ed and isolated rhizospheric strains of Trichoderma in soybean and other plant species, demonstrating their potential for both biocontrol and promoting plant growth(Zhang et al 2017;Liu et al 2020;Yu et al 2021).…”

Aims Bioformulations with Trichoderma strains offer cost-effective and sustainable options for integrated disease management and plant nutrition. Therefore, this study aimed selected new isolates of Trichoderma with antagonistic and plant growth promotion abilities, including the effect of inoculation of isolates on the early development of soybean seedlings. Methods Trichoderma isolated from the soybean rhizosphere were screenings assessed their antagonistic activity against three phytopathogens, as well as their capability for indole-3-acetic acid (IAA) synthesis and phosphate solubilization. Three promising isolates were further examined for their tolerance to various in vitro conditions and agrochemicals. Single and co-inoculation experiments to assess their effects on growth, chlorophyll, carotenoids, proteins, flavonoids, and phenolic compounds during early soybean development. Results T. viride GT-8, T. reesei GT-31, and T. longibrachiatum GT-32 demonstrated antagonism against phytopathogens. GT-31 and GT-32 exhibited higher IAA synthesis (175.8 ± 2.4 µg/mL and 119.6 ± 11.2 µg/mL, respectively), while GT-8 showed superior phosphate solubilization (28.56 ± 0.4 µg P/mL). All three fungi displayed robust growth under various conditions and agrochemical treatments. Trichoderma inoculation significantly enhanced shoot and root growth, with co-inoculation resulting in even higher dry shoot and root weights, increasing by 50.3% and 48.8%, respectively, compared to non-inoculated seedlings. Trichoderma-inoculated plants also exhibited elevated chlorophyll, carotenoids, flavonoids, and phenolic compounds. Conclusion Overall, these findings highlight the potential of these novel Trichoderma isolates for formulating bioformulations that can enhance plant growth and offer benefits in soybean crops, providing a sustainable strategy for agriculture.
