Review Questions

• How do Trichoderma fungi contribute to plant health in soil ecosystems?
  • Trichoderma fungi contribute to plant health by enhancing nutrient uptake, promoting root growth, and protecting against soil-borne pathogens. They produce enzymes that decompose organic material, enriching the soil and making nutrients more available to plants. Additionally, their ability to outcompete harmful fungi helps maintain a healthy balance in the soil microbiome.
• Discuss the role of Trichoderma fungi in sustainable agriculture and their applications in pest management.
  • In sustainable agriculture, Trichoderma fungi serve as biocontrol agents that can suppress diseases caused by soil-borne pathogens. By using these fungi as biopesticides, farmers can reduce reliance on chemical pesticides, promoting healthier ecosystems. Their dual role as both a biocontrol agent and a biofertilizer enhances crop yields while maintaining environmental integrity.
• Evaluate the potential of Trichoderma fungi in addressing challenges posed by climate change on agricultural systems.
  • Trichoderma fungi have significant potential in mitigating the impacts of climate change on agricultural systems by enhancing plant resilience to environmental stresses such as drought and salinity. Their ability to improve root development leads to better water retention and nutrient uptake during adverse conditions. Additionally, utilizing Trichoderma can promote sustainable farming practices that reduce greenhouse gas emissions associated with conventional agriculture, creating a more resilient agricultural landscape.
