**5. Conclusion**

Today, food security is dependent on crop protection and fungicide-based plant protection is indispensable for efficient and large-scale crop production. As it takes a long time to develop new fungicides, it is necessary to take proper care to avoid the development of fungicidal resistance. In single-target fungicidal resistance, development may occur within a few years and fungicides with novel modes of action are found rarely. The earlier strategy was to apply single-target fungicides, which impose a strong selection pressure for the development of resistant mutants. The fungicides with more than one target are not easily overcome by mutations. Hence, there is a need to explore and enhance the existing host resistance against the potato pathogen. Among all, transgenic approach is the most promising to avoid the risk of development of fungicidal resistance; use of alternatives like green chemicals, bio-agents and explore and enhance the host resistance.
