**4. Conclusions**

*Trichoderma* is one of the most important fungi in agriculture. It has demonstrated many capabilities to be used as biofertilizers as well as biofungicides. It has also shown its sustainability and various mechanisms of providing the crop with nutrients. Moreover, it has various control mechanisms for various plant pathogens, which gives it an advantage when compared to other phytopathogen control mechanisms. It is therefore an option for farmers to use for sustainable cropping and increase in yields and quality of the produce.
