“…Numerous studies have reported the nematicidal activity of Trichoderma against a variety of plant-parasitic nematodes. For example, in a study by Kumar (2020), the nematicidal activity of Trichoderma harzianum was evaluated against the root-knot nematode Meloidogyne incognita in tomato plants. The researchers found that application of T. harzianum significantly reduced nematode population density in the soil and improved plant growth and yield compared to the untreated control.…”

Trichoderma is a genus of fungi that has been widely studied for its ability to act as a biocontrol agent against plant pathogens. This review summarizes recent research on the mechanisms of action of Trichoderma as a biocontrol agent and its potential for use in sustainable agriculture. Trichoderma can control plant pathogens through various mechanisms, including competition for nutrients and space, mycoparasitism, and induction of systemic resistance in the host plant. The effectiveness of Trichoderma as a biocontrol agent depends on various factors, such as the species and strain used, the timing and method of application, and the environmental conditions. In addition to its biocontrol properties, Trichoderma can also promote plant growth and health by improving nutrient uptake and stress tolerance. However, the implementation of Trichoderma as a biocontrol agent in agriculture faces some challenges, such as the lack of standardized methods for production and application, and the need for further research to understand its interactions with other soil microorganisms. Overall, Trichoderma shows great potential as a sustainable alternative to chemical pesticides in agriculture, and further research and development are needed to maximize its efficacy and integration into farming practices.

“…The combination of both strategies makes nematode attack more efficient ( Luo et al., 2007 ). However, the use of toxin-producing fungi for the management of nematodes in crops has not been widely studied because of possible “non-target” effects ( Kumar, 2020 ). Pleurotus ostreatus has recently been shown to induce paralysis of the sensory cilia and calcium accumulation in the nematode, which results in nematode nervous system tissue necrosis ( Lee et al., 2005 ).…”

Plants are exposed to large number of threats caused by herbivores and pathogens which cause important losses on crops. Plant pathogens such as nematodes can cause severe damage and losses in food security crops worldwide. Chemical pesticides were extendedly used for nematode management. However, due to their adverse effects on human health and the environment, they are now facing strong limitations by regulatory organisations such as EFSA (European Food Safety Authority). Therefore, there is an urgent need for alternative and efficient control measures, such as biological control agents or bio-based plant protection compounds. In this scenario, chitosan, a non-toxic polymer obtained from seafood waste mainly, is becoming increasingly important. Chitosan is the N-deacetylated form of chitin. Chitosan is effective in the control of plant pests and diseases. It also induces plants defence mechanisms. Chitosan is also compatible with some biocontrol microorganisms mainly entomopathogenic and nematophagous fungi. Some of them are antagonists of nematode pests of plants and animals. The nematophagous biocontrol fungus Pochonia chlamydosporia has been widely studied for sustainable management of nematodes affecting economically important crops and for its capability to grow with chitosan as only nutrient source. This fungus infects nematode eggs using hyphal tips and appressoria. Pochonia chlamydosporia also colonizes plant roots endophytically, stimulating plant defences by induction of salicylic and jasmonic acid biosynthesis and favours plant growth and development. Therefore, the combined use of chitosan and nematophagous fungi could be a novel strategy for the biological control of nematodes and other root pathogens of food security crops.
