“…One of the great challenges in the transition from conventional to organic agriculture is the adaptation of introduced beneficial microorganisms (e.g., biological control and bioremediation agents) to a crop field with residual agrochemicals (Gharieb et al, 2004;Shen et al, 2019), or in areas where agrochemicals and antagonistic microorganisms are applied at the same time (Mishra et al, 2014;Nongmaithem, 2015;Palazzini et al, 2018). An alternative and rich guild of microorganisms adapted to these conditions are endophytic fungi, which inhabit the interior tissue of plants without causing apparent disease symptoms, facilitate plant adaptation to the environment, and may act as antagonists against phytopathogens; thus, they can be used as biological control and bioremediation agents (Harman, 2007;Howell, 2007;Stamatiu-Sánchez et al, 2014;Deng and Cao, 2017;Khan and Mohiddin, 2018;Holanda et al, 2019;Pietro-Souza et al, 2020).…”

The transition from conventional to organic agriculture is often challenged by the adaptation of biological control agents to environments heavily exposed to agrochemical pollutants. We studied Trichoderma species isolated from living leaf tissues of wild Rubiacaeae (coffee family) plants to determine their fungicide tolerance and potential for bioremoval. First, we assessed the in vitro tolerance to fungicides of four Trichoderma isolates (Trichoderma rifaii T1, T. aff. crassum T2, T. aff. atroviride T3, and T. aff. strigosellum T4) by placing mycelial plugs onto solid media supplemented with seven different systemic and non-systemic fungicides. After a week, most of the fungicides did not significantly inhibit the growth of the isolates, except in the case of cyproconazole, where the only isolate able to grow was T1; however, the colony morphology was affected by the presence of fungicides. Second, biological removal potential was established for selected isolates. For this experiment, the isolates T1, T2, and T4 were independently inoculated into liquid media with the fungicides azoxystrobin, chlorothalonil, cyproconazole, and trifloxystrobin. After 14 days of incubation, a removal of up to 89% was achieved for chlorothalonil, 46.4% for cyproconazole, and 33.1% for trifloxystrobin using viable biomass. In the case of azoxystrobin, the highest removal (82.2%) occurred by adsorption to fungal biomass. Ecotoxicological tests in Daphnia magna revealed that T1 has the highest removal potential, achieving significant elimination of every fungicide, while simultaneously detoxifying the aqueous matrix (except in the case of cyproconazole). Isolate T4 also exhibited an intermediate efficiency, while isolate T2 was unable to detoxify the matrix in most cases. The removal and detoxification of cyproconazole failed with all the isolates. These findings suggest that endosphere of wild plants could be an attractive guild to find new Trichoderma species with promising bioremediation capabilities. In addition, the results demonstrate that attention should be placed when combining certain types of agrochemicals with antagonistic fungi in Integrated Pest and Disease Management strategies or when transitioning to organic agriculture.

Protection against pests, pathogens, and weeds is crucial for agroecosystem management to prevent significant crop losses (Oerke, 2006). Chemical pesticides, widely used since the 1960s, have led to numerous negative impacts, including harm to human health and changes to biodiversity (Deguine et al., 2023). Around the world, sustainable agriculture efforts are underway to find a balance between preserving the environment and ensuring food security. To address this, a shift towards environmentally friendly methods is underway in sustainable agriculture, using innovative strategies that reduce exposure to pesticides and their negative impacts (Deguine et al., 2023). A new generation of bioproducts is being developed, using volatile compounds from plants and microorganisms. In this sense, the latest advancements in agriculture include bioproducts derived from bacteria and fungi, products utilizing monoterpenes and other volatile compounds to safeguard crops from pests and diseases, and bioproducts to boost crop yield along with carrier materials that offer stability, protection, and control.Consequently, this Research Topic focuses on developing new formulations of ecofriendly biopesticides, studying soil microorganisms and plant-derived bioactive compounds, and exploring new techniques for bioproduct development.A publication titled "Effect of Neo-Boost Pesticide on Mortality and Development of Tetranychus urticae" is presented by Bruinsma et al. The authors show the need for additional pesticides with different modes of action. The study recommends field doses depending on the developmental stages of T. urticae. Neo-Boost has high efficiency against larvae, moderate efficiency against adults, and no effect on eggs of T. urticae. The study also shows that Neo-Boost could enhance plant defenses against mites and has the potential to be used as a novel acaricide or combined with other ingredients for more potent mite control. They demonstrate the efficacy of Neo-Boost, which could be used in its current formulation or combined with other active ingredients.On the other hand, Loṕez et al. review the use of essential oils and derivatives as biopesticides in "New insights into biopesticides: solid and liquid formulations of essential Frontiers in Agronomy frontiersin.org 01
