Special Issue Information

Dear Colleagues,

Fungi from the genus Trichoderma are widely distributed in the environment. They occur in all climate zones and inhabit various ecological niches. Trichoderma spp. interact with bacteria, viruses, and pathogenic fungi through competition, hyperparasitism, and antibiosis. Trichoderma spp. induce systemic resistance in both monocot and dicot plants as a result of biotic and abiotic stresses. Due to these properties, they are classified as biological control agents and are commercially used in the production of plant protection products as biopesticides or biostimulants. Some researchers suggest that Trichoderma spp. stimulate plant growth by enabling plants to absorb greater amounts of nutrients and by supporting the production of vitamins and growth regulators. Currently, many Trichoderma bioinoculants are available on the market, and mixed strains are becoming increasingly popular due to their enhanced synergistic effects. Research is being conducted worldwide to determine the impact of Trichoderma spp. on plants from various groups. The main aim of this Special Issue is to compile the latest research findings, providing a broad range of results concerning the use of Trichoderma fungi in crop cultivation.

Regenerative agriculture is oriented around restoring soil health through natural processes. In this context, soil biota plays a central role, and bioinoculation represents a potentially effective approach for targeted modification of microbial communities. Among beneficial microorganisms, Trichoderma atroviride is prominent for its biocontrol agent (BCA) activity against plant-parasitic nematodes (PPNs), whereas its effects on free-living nematodes (FLNs) under in vivo conditions remain insufficiently explored. The aim of this study was to assess the response of nematode communities to bioinoculation with T. atroviride as an indicator of soil functional status. A three-year field study was conducted in organic olive orchards at Vodnjan and Nadin on four autochthonous olive cultivars, applying two inoculum doses of T. atroviride: 1 × 106 spores mL−1 (LD) and 1 × 108 spores mL−1 (HD). Bioinoculation increased the diversity of the soil nematode communities at both locations. However, the responses differed between the two inoculum doses. Both doses were associated with an increased abundance of FLNs and a reduced abundance of herbivorous nematodes relative to the control, with LD showing a more consistent and ecologically favourable effect. In combination with biotic and abiotic factors, the LD dose was associated with greater trophic diversity and a more structured soil food web, whereas increasing the inoculum concentration (HD) did not result in additional functional improvement.

Tropaeolum majus L. is a popular ornamental plant. All parts of T. majus plant (flowers, leaves, and seeds) are edible and are appreciated for their pungent taste, although their chemical composition varies. T. majus is known for its many health benefits. It is a source of trace elements and bioactive compounds that are easily absorbed by the human body. The flowers of T. majus contain flavonoids from the flavone and flavonol groups, as well as their glycosides, which exhibit antibacterial, antifungal and antiviral activity. They also inhibit the activity of certain enzymes. Among the flavonoids, the flowers and leaves of T. majus contain derivatives of kaempferol and quercetin. Flavonoids also include anthocyanins, which are responsible for the color of T. majus flowers. In red flowers, delphinidin predominates; in orange flowers, pelargonidin; and in yellow flowers, pelargonidin and delphinidin are present in similar amounts. In the flowers of T. majus, seven carotenoids have been identified: violaxanthin, antheraxanthin, lutein, zeaxanthin, α, β and γ-carotene. In the leaves, however, lutein, violaxanthin, β-carotene and neoxanthin were detected. In T. majus, the presence of two glucosinolates has been reported: glucotropaeolin and sinalbin. The flowers and leaves of T. majus also contain both macroelements (N, P, K, Ca, Mg, Na) and microelements (Fe, Mn, Cu, Zn, Mo), and essential oils which have anti-cancer, antibacterial, and antiviral properties. The quality and flowering of T. majus are enhanced by fungi of the Trichoderma genus, which is important both ecologically and in terms of increasing the yield of raw material extracted from the plant. T. aureoviride, T. hamatum, and T. harzianum stimulated the flowering of the T. majus ‘Spitfire’. The plants treated with T. harzianum after being planted in pots flowered the most abundantly. Trichoderma spp. caused the plants to grow more intensively, producing longer and more leafy shoots with a greater number of offshoots. Trichoderma spp. stimulated the uptake of macronutrients, except for P. In the case of Ca and Na, this phenomenon was only observed in plants treated with T. aureoviride and T. hamatum, and for Mg, only when T. hamatum was applied to sown seeds. As for the developed root systems, as far as the micronutrients are concerned, Trichoderma spp. stimulated the uptake of Zn and Mn. Additionally, there was a higher Fe content in the plants treated with T. harzianum on both dates and T. aureoviride after planting the plants in pots. Full article
