“…Results of the present study showed that when either T. harzianum or T. viridi were used in combination with 3% dry biomass of C. album, the effect on plant growth and yield was same as that of application of 3% dry biomass alone. By contrast, recently Javaid et al (2017) reported that application of dry biomass of a brassicaceous weed Sisymbrium irio in combination with T. harzianum gave significantly higher crop growth and yield of mung bean when compared to application of either alone. In the present study, individual application of either T. harzianum or T. viridi significantly enhanced crop growth and yield under stress of S. rolfsii.…”

Sclerotium rolfsii is a soil-borne plant pathogen that causes root diseases in hundreds of plant species. It also causes collar rot disease in chickpea (Cicer arietinum L.). The present pot study was carried out to investigate the effect of soil amendment with dry biomass of a weed Chenopodium album L. and two antagonistic fungi, namely Trichoderma harzianum and T. viride, on growth and yield of chickpea variety Noor 2009 in soil infected with S. rolfsii. The pathogen-contaminated soil was amended either with 1, 2, or 3% C. album dry biomass, T. harzianum, and T. viride alone, or combinations of either of the two Trichoderma species and plant dry biomass. The lowest shoot and root dry biomass and grain yield of chickpea were recorded in S. rolfsii inoculation alone without any soil amendment (positive control). Plant growth and yield were significantly and gradually increased over positive control with an increase in C. album dry biomass application in the soil. Likewise, soil application of either of the two Trichoderma species significantly enhanced plant growth and yield over positive control under biotic stress of S. rolfsii. Combined application of either T. harzianum or T. viride with 3% dry biomass of C. album also proved highly effective in alleviating biotic stress of S. rolfsii on growth and yield of chickpea.

“…Many synthetic fungicides have shown promising results in severe disease infected areas but their application has recently been restricted because of pathogen resistance, pesticide residue, phytotoxicity, human health hazards, and environmental pollution (Mitrani et al, 2018). In this context, biological control based on beneficial microorganisms as well as natural plant products are used as eco-friendly approaches that can provide promising alternates to overcome the spread of charcoal rot pathogen of mungbean (Banaras et al, 2020;Javaid et al, 2017Javaid et al, , 2018. Several antagonistic fungi are available for the control of soil-borne fungal pathogens (Ali et al, 2020;Bisutti et al, 2017).…”

In the present study, two Aspergillus species as biocontrol agents together with Chenopodium quinoa dry biomass were used to investigate their effects on histochemical features of mungbean plant inoculated with M. phaseolina. In a pot experiment, Aspergillus flavipes and Aspergillus versicolor were added either alone or together with 1%, 2%, and 3% dry biomass of quinoa (DBQ) to the pot soil already inoculated with M. phaseolina. After 4 weeks of sowing, root and lower-stem sections of the mungbean plants were stained with ferric chloride, phloroglucinol-HCl and Lugol's iodine to detect the presence of polyphenols, lignin, and starch granules, respectively, and observed under light microscope. Stem and root sections were also observed under scanning electron microscope (SEM) to reveal the effect of soil amendments on cell structures. The findings revealed that mungbean plant cross sections from all the treatments except positive control (only inoculated with M. phaseolina) showed very clear cell structures. In positive control, distorted, fragmented, and collapsed cell structures were observed. Moreover, M. phaseolina blocked vascular vessels in comparison to negative control where the cell structures were intact and normal in size. Plant sections from treatments with A. flavipes and A. versicolor alone or together with DBQ were without pathogen colonization, with normal cell structures and a high deposition of gel. The results suggested that the two Aspergillus spp. and C. quinoa induced defense responses in mungbean plants.

“…Trichoderma spp. act as biocontrol organisms and also stimulate the plant resistance and growth resulting in overall improvement in yield (Javaid et al 2017;. The biocontrol activity related to antibiotics and mycoparasitism also improves defense response or systemic resistance in plants (Naher et al 2014).…”

Fungi in the genus Trichoderma are widely used as biological control agents because they can suppress plant pathogens and activate plant defense systems. In the present study, efficacy of microbial antagonists viz., T. harzianum and T. viride or their combination was evaluated against the pathogenic fungus Macrophomina phaseolina and their effect on enzymatic activities and phenol content of soybean [Glycine max (L.) Merr.] plants. Soybean seeds were inoculated with T. harzianum and T. viride separately or in combination, and sown in pots under green house and under field conditions. Host enzymatic activities and phenol levels were measured at 14, 28 and 42 days after sowing (DAS) in both field and greenhouse experiments. Seed treatments with T. harzianum, T. viride or their combination increased peroxidase, polyphenol oxidase and β-1, 3-glucanase activities, and also the total phenol content in soybean leaves as compared to a non-treated control treatment. Concentration of peroxidase and β-1, 3-glucanasepeaked at 14 DAS and decreased thereafter in all the treatments under greenhouse and field conditions. All the treatments showed the highest levels of total phenols and polyphenol-oxidase at 28 DAS under both greenhouse and field conditions. At 14 DAS in both trials, the combination of T. viride + T. harzianum resulted in the highest level of peroxidase and β-1, 3-glucanase activities. This combination also resulted in the highest levels of total phenols and polyphenol oxidase content at 28 DAS. Our findings demonstrated that application of Trichoderma species as seed treatment has potential to trigger key mechanisms of systemically acquired resistance in soybean, and thereby enhanced efficacy of disease management tactics. © 2021 Friends Science Publishers
