“…These tested bioagents significantly reduced the leaf blight severity and increased the green fodder yield over untreated control. Present findings are in confirmation with observations of Malik et al (2018) who have tested T. harzianum and T. viride against MLB and banded leaf and sheath blight under field conditions. It can be therefore assumed that the antifungal role of Trichoderma may be due to combination of hydrolytic enzymes and secondary antifungal metabolites such as trichodermin, trichodermal, etc.…”

Two indigenous isolates of Trichoderma isolated from rhizosphere soils of maize plants were identified as T. harzianum and assessed for antagonistic activity against Bipolaris maydis causing maydis leaf blight in fodder maizein vitro,and under field conditions for two consecutive kharif seasons of 2016 and 2017. Dual culture assay of T. harzianum isolates showed significantly higher degree of mycelial inhibition (74.35%) againstB. maydis. Similarly, under field conditions, seed treatment andfoliar spray of T. harzianum-I provided highest reduction in leaf blight severity (54.86%) along with 19.03 percent increase in green fodder yieldin comparison to control. The efficacy of T. harzianum isolates to boost defence responses against maydis leaf blight disease in maize was also evaluated in bioagents treated leaves. Plants treated with biocontrol agents showed significantly higher activities of antioxidative defence enzymes like peroxidase (POX), superoxide dismutase (SOD) and catalase (CAT). In treated leaves, the activities of POX and SOD reached maximum at 24 h and activity of CAT reached the highest at 36 h after inoculation of pathogen B. maydis. Enzyme activities induced by T. harzianum isolates were more obvious than that induced by pathogen only. This implies that biocontrol agent induced defence responses against maydis leaf blight pathogen in fodder maize.

“…Thus the bio-control agent Trichoderma viridae and Trichoderma harzianum. as suggested by Kumar et al, (2009) and Ashlesha et al, (2019) respectively and the plant extracts Garlic as reported by Kumar et al, (2009a) and Sarpagandha by Malik et al, (2018) are effective alternatives to chemicals in managing the disease and increasing the yield. Thus Use of plant products (secondary metabolites from plants) in disease management was the recent eco-friendly approach and gaining popularity because of its advantages over chemicals (Gurjar et al, 2012).…”

“…It is well known that plant protection mediated by Trichoderma spp. can be deeply influenced by environmental conditions and ecological fitness of biocontrol agents hence being poorly predictable a priori (Howell, 2003;Alabouvette et al, 2009;Lecomte et al, 2016;Malik et al, 2018).…”

Trichoderma spp. are among the most widely used plant beneficial fungi in agriculture. A novel approach to enhance their effectiveness in plant defense is to use the fungi in combination with bioactive molecules including plant-derived compounds. Here, we show that plant treatment with Trichoderma afroharzianum (strain T22) and Systemin (Sys), a tomato plant peptide active in triggering plant defense, confers protection against the fungal pathogens Fusarium oxysporum, Botrytis cinerea and the insect pest Tuta absoluta. The observed defensive response was associated with increased accumulation of metabolites and transcripts involved in the Jasmonic acid (JA) pathway. Our findings suggest that the innovative combination of T. afroharzianum T22 and Sys can result in a more effective and robust control of different biotic stress agents.
