“…Trichoderma is considered the largest taxon among the fungicolous fungal genera with many ubiquitously distributed species (Kubicek et al 2019). Trichoderma is a ubiquitous genus, belongs to the Ascomyceta division, filamentous saprophytic fungus and is opportunistic plant symbionts, which commonly colonize soils rich in organic matter (Macías-Rodríguez et al 2020). These fungi typically inhabit several soils including clay and sand and in tropical soils (Bononi et al 2020).This fungus also could proliferate freely in soils and/or shows symbiotic relation with the roots of cultivated plants and foliar parts (Sachdev and Singh, 2020).…”

“…More than 479 volatile organic compounds have been identified, which are produced by Trichoderma (e.g., alkanes, alcohols, furans, ketones and pyrones). These compounds are strain-specific, which their production depends on the components of the growth media on which they are grown (González-Pérez et al 2018;Macías-Rodríguez et al 2020).The most versatile species of the genus Trichoderma may include the following :…”

“…These interactions also may include both detrimental and beneficial at multiple trophic levels (Kredics et al 2018). Cultivated plants face a lot of aggressors including pathogenic microorganisms and herbivorous arthropods, which activate plant corresponding signaling defense mechanisms (Macías-Rodríguez et al 2020). Under certain circumstances, however, these plants are beinga target for multiple aggressors, thensome pathways could have profound effects on plant defense and resistance to attack (Macías-Rodríguez et al 2020).…”

T HE world's burgeoning population faces a great challenge concerning food security, which could be achieved through different sustainable agricultural practices. Trichoderma, as a ubiquitous fungus, is one of the most promising microorganisms that might offer several avenues for sustainable agriculture. Trichoderma spp. may guarantee a better solution for conventional problems in agriculture through several approaches including the protection of cultivated plants from undesirable abiotic and biotic conditions under changing environments and promoting their growth in poor or limited soil nutrients. The promising role of Trichoderma for vegetable production as a biocontrol and biofertilizers has been confirmed but its role as a plant pathogen still needs more studies. Trichoderma could inhibit or suppress the growth of soil phytopathogens, promoting plant growth and soil health, through activation of many mechanisms including synthesis of antibiotics, mycoparasitism and competition for nutrients and space against plant deleterious microorganisms. The sustainable approaches of Trichoderma including biofortification, bio-remediation and phyto-remediationas well as exploring future research opportunities will be also addressed in this work.

BACKGROUND Trichoderma spp. are soil fungi that interact with plant roots and associated biota such as other microorganisms and soil fauna. However, information about their interactions with root‐feeding insects is limited. Here, interactions between Trichoderma harzianum and the root‐feeding insect Phyllophaga vetula, a common insect pest in maize agroecosystems, were examined. RESULTS Applications of T. harzianum and P. vetula to the root system increased and decreased maize growth, respectively. Induced tolerance against herbivore attack was provided by T. harzianum maintaining a robust and functional root system as evidenced by the increased uptake of Cu, Ca, Mg, Na and K. Herbivore tolerance also coincided with changes in the emission of root volatile terpenes known to induce indirect defense responses and attract natural enemies of the herbivore. More importantly, T. harzianum induced de novo emission of several sesquiterpenes such as β‐caryophyllene and δ‐cadinene. In addition, single and combined applications of T. harzianum and P. vetula altered the sucrose content of the roots. Finally, T. harzianum produced 6‐pentyl‐2H‐pyran‐2‐one (6‐PP) a volatile compound that may act as an antifeedant‐signaling compound mitigating root herbivory by P. vetula. CONCLUSION Our results provide novel information about belowground multitrophic plant–microbe–arthropod interactions between T. harzianum and P. vetula in the maize rhizosphere resulting in alterations in maize phenotypic plant responses, inducing root herbivore tolerance.

Background: The meadow spittlebug Philaenus spumarius L. is the vector for the bacterium Xylella fastidiosa subspecies pauca, involved in olive quick decline syndrome (OQDS) in Salento (Italy). Control of P. spumarius is key to limiting transmission of the bacterium, and an innovative approach can be based on effective natural compounds and biocontrol agents. Entomopathogenic fungi are an important source of bioactive natural molecules that play a role in the relationship between microorganisms and insects.Results: Pathogenicity bioassays, performed by dipping adults of P. spumarius in either fungal culture suspension (120 mg mL −1 ) or cell-free culture supernatant of Trichoderma chlorosporum GJS 91-150, showed, respectively, 97% and 87% death within 24 h. The effect was dose-dependent. In laboratory bioassays, the powdered fungal culture of T. chlorosporum GJS 91-150 did not exhibit pathogenic activity when injected into nymph spittle. Conclusions: T. chlorosporum GJS 91-150 affected the survival of P. spumarius adults. The lethal effect was not associated with the development of mycelium on the cuticle, but seems due, at least partly, to fungal metabolites released in the culture medium. The fungus tested here has good potential for the development of effective low-environmental impact control strategies for P. spumarius and suppression of X. fastidiosa.
