“…The volatile and non-volatile metabolites produced by various species of Trichoderma are described under separate section. In our recent study, cell-free culture filtrate of T. pseudokoningii showed efficacy against C. capsici, S. sclerotiorum, R. solani, and F. oxysporum due to release of extracellular SMs (Dutta et al, 2018).…”

“…The secretion of particular lytic enzymes from the cell wall of Trichoderma viz., glucanases, chitinases, pectinases, and peptaibol antibiotics induced a cascade of physiological changes within the target fungus facilitating flow of nutrients to the mycoparasite and degeneration of target fungus (Howell, 2003). Mycoparasitic ability of Trichoderma species have been studied against various soilborne pathogens, such as Fusarium oxysporum, F. solani, R. solani, S. sclerotiorum, S. rolfsii, and Colletotrichum capsici in our earlier studies (Dutta and Das, 1999a;Dutta and Das, 2002;Dutta and Das, 2009;Dutta et al, 2018;.…”

Biological control of plant pathogens has become increasingly possible with the use of fungi, which have a high reproductive rate (both sexually and asexually) and a short generation time and are very specific to their target. Trichoderma species are found in diverse habitats and experience various interactions with other organisms. They are used as bio-fungicides owing to their plant-protecting abilities, and they produce a large number of secondary metabolites (SMs) accompanied by enrichment in secondary metabolism-associated genes. This article aims to review and discuss the SMs produced by Trichoderma species, including their physiology, mode of action, mass production, and industrial and field applications for the control of plant diseases. We also discuss the evolutionary history, taxonomical gradient, classification, and ecology of Trichoderma species, as well as indirect and direct mechanisms used as plant protectors with gene improvement strategies. Aside from the bioactivity of SMs derived from Trichoderma species, compatibility with fungicides, mass formulation techniques, and industrial applications of Trichoderma species, the review focuses on its advent and progress as a global research pioneer.

“…A fungal mycelial plug with a diameter of 5 mm was obtained from a pure culture of fungus M. phaseolina and inoculated into all the Petri dishes, including the untreated control [65]. The inoculated Petri dishes were sealed with paraffin film and incubated in a BOD at 27 ± 1 • C. The experiment comprised three replicates for each treatment, and the percentage of growth inhibition was calculated after 7 days of inoculation using the formula of [66,67] Mycelial growth inhibition = Dc − Dt Dc × 100 where Dc (mm) = diameter of control set and Dt (mm) = diameter of treated set.…”

Zinc oxide nanoparticles (ZnO NPs) exhibit diverse applications, including antimicrobial, UV-blocking, and catalytic properties, due to their unique structure and properties. This study focused on the characterization of zinc oxide nanoparticles (ZnO NPs) synthesized from Juglans regia leaves and their application in mitigating the impact of simultaneous infection by Meloidogyne arenaria (root-knot nematode) and Macrophomina phaseolina (root-rot fungus) in cowpea plants. The characterization of ZnO NPs was carried out through various analytical techniques, including UV–visible spectrophotometry, Powder-XRD analysis, FT-IR spectroscopy, and SEM-EDX analysis. The study confirmed the successful synthesis of ZnO NPs with a hexagonal wurtzite structure and exceptional purity. Under in vitro conditions, ZnO NPs exhibited significant nematicidal and antifungal activities. The mortality of M. arenaria juveniles increased with rising ZnO NP concentrations, and a similar trend was observed in the inhibition of M. phaseolina mycelial growth. SEM studies revealed physical damage to nematodes and structural distortions in fungal hyphae due to ZnO NP treatment. In infected cowpea plants, ZnO NPs significantly improved plant growth parameters, including plant length, fresh mass, and dry mass, especially at higher concentrations. Leghemoglobin content and the number of root nodules also increased after ZnO NP treatment. Additionally, ZnO NPs reduced gall formation and egg mass production by M. arenaria nematodes and effectively inhibited the growth of M. phaseolina in the roots. Furthermore, histochemical analyses demonstrated a reduction in oxidative stress, as indicated by decreased levels of reactive oxygen species (ROS) and lipid peroxidation in ZnO NP-treated plants. These findings highlight the potential of green-synthesized ZnO NPs as an eco-friendly and effective solution to manage disease complex in cowpea caused by simultaneous nematode and fungal infections.
