Trichoderma is a common soil fungus that aids in decomposition of agricultural waste and acts as a biological control agent against soilborne pathogens. It can be used to speed up the composting process through passive or active methods. As a decomposer, Trichoderma breaks down organic matter like manure and plant debris to create compost which improves soil fertility. As a biological control, Trichoderma can be applied through seed treatment, soil treatment, or other methods to control plant diseases under favorable temperature, moisture, and soil conditions.
