“…This may be related to the accuracy and adaptability of the two methods ( Murray et al, 2011 ). The increased abundance of Aspergillus , Penicillium , and Trichoderma was probably related to the degradation of polycyclic aromatic hydrocarbons in the biochar via the production of enzymes ( Anyika et al, 2015 ; Al-Hawash et al, 2018 ), which was in agreement with other studies ( Jaiswal et al, 2017 , 2018 ; Vecstaudza et al, 2018 ). Several authors have reported that C. globosum , Aspergillus , Penicillium , and Trichoderma could control plant diseases caused by Phytophthora spp.…”

Biochar is a new eco-material with the potential to control soilborne diseases. This study explored the relationship between the rhizosphere fungal community and the suppression of Phytophthora blight of pepper in the context of time after biochar application. A pot experiment was conducted and rhizosphere soils were sampled to determine the biochar-induced soil chemical properties, fungal community composition, and abundance of biocontrol fungi. The biochar-enriched fungal strains were screened by the selective isolation method, and their control effects against Phytophthora blight of pepper were determined using a pot experiment. Biochar treatments effectively inhibited pathogen growth and controlled the disease, with biochar applied immediately before planting (BC0) having greater effects than that applied 20 days before planting (BC20). Compared to the control, biochar-amended rhizosphere soils had a higher pH, available nutrient content, and fungal richness and diversity. Moreover, biochar treatments significantly increased the abundance of potential biocontrol fungi. The proliferation in BC0 was stronger as compared to that in BC20. Several strains belonging to Aspergillus, Chaetomium, and Trichoderma, which were enriched by biochar amendment, demonstrated effective control of Phytophthora blight of pepper. Canonical correspondence and Pearson's correlation analysis showed that a high content of soilavailable nutrients in biochar treatments was favorable to the proliferation of beneficial fungi, which was negatively correlated with both the abundance of Phytophthora capsici and disease severity. In conclusion, biochar-mediated improvement in the fungal community suppressed the Phytophthora blight of pepper. The biochar application time had a great impact on the control effect, possibly due to the short-term proliferative effect of the biochar on biocontrol fungi.

“…However, the BCH + T. harzianum association for control of the disease evaluated in this study showed high effectiveness in phytopathogen inhibition compared with the other treatments, resulting in a greater difference in mass (g) in relation to the inoculated control. Similarly, Trichoderma viride applied to the soil altered the biodynamics of rye plants (Secale cereale L.), increasing the number of leaves in relation to the control [31]. The authors observed that use of wood Treatment of seeds with a specific T. harzianum isolate caused an increase in growth of the bean plants, resulting in a larger leaf area, root area and a greater number of secondary roots [32].…”

This study is based on the importance of biological control methods and the lack of information on the effect of biochar (BCH) from sewage sludge associated or not with Trichoderma harzianum on the control of Macrophomina phaseolina in the bean crop (Phaseolus vulgaris, cv. BRS Estilo). Biochar from sewage sludge, pyrolyzed at 500 ºC and used in low concentration (0.5%), has a direct effect on the in vitro control of M. phaseolina. However, higher BCH concentrations stimulated the growth of the pathogen. In culture medium with or without BCH, T. harzianum (strain 1306) inhibited the mycelial growth of M. phaseolina. The addition of BCH + T. harzianum reduced the deleterious effects caused by M. phaseolina on bean plants. This study demonstrated that joint application of BCH from sewage sludge + T. harzianum considerably increased the fresh and dry mass of bean plants, inoculated or not with M. phaseolina.

“…Seed treatment with T. harzianum resulted in an increase in bean plant growth, resulting in greater leaf area, root area and higher number of secondary roots (Pereira et al, 2014). Similarly, Trichoderma viride applied to the soil altered the biodynamics of rye plants (Secale cereale L.), increasing the number of leaves in relation to the control (Vecstaudza et al, 2018). The authors observed that use of wood biochar resulted in better survival of Trichoderma spp.…”

The synergistic effect of sewage sludge biochar and Trichoderma harzianum on soybean yield

The use of sewage sludge to produce biochar is one of the best alternatives for the final destination of this material, allowing for reuse of nutrients and reducing the dependence on mineral fertilizers. Sewage sludge biochar (SSB) stands out as an enhancer of the physical, chemical and biological properties of the soil. The use of beneficial microorganisms such as Trichoderma spp. in combination with biochar may have a synergistic effect on the development of different plants and needs to be better studied. The SSB was produced from sewage sludge biomass (SS) obtained from the sewage treatment plant (STP) of the Federal District Environmental Sanitation Company (CAESB), Brasilia, DF, Brazil. The SSB was produced in an electric tubular furnace at 500 °C and showed the following characteristics: carbon (19%), nitrogen (2.3%), hydrogen (1.7%), specific surface area (52.5 m2 g-1), pore volume (0.053 ml g-1). An experiment was carried out in a greenhouse to evaluate the synergistic effect of SSB application (0.5% w/w) in combination with T. harzianum (TH) on soybean development. The treatments adopted were: (1) control – autoclaved soil, (2) TH, (3) SSB and (4) SSB + TH. The SSB was applied 15 days before soybean planting and the TH was applied to the soil two times, once at eight days before planting and the other at the time of planting. The SSB resulted in a 200% increase in the number of pods when compared to the exclusive application of T. harzianum. Application of SSB with T. harzianum increased germination by 20%, as well as a 70% increase in fresh and dry soybean mass in relation to the control. The agronomic indices evaluated in this study demonstrated that the use of SSB in conjunction with T. harzianum presents a synergistic effect, allowing for better development of the soybean plants.
