Abstract

Emerging pathogens are not a new concern in agriculture but have gained more attention due to their increasing frequency and severity. A well-known example is the potato late blight, which was brought on by the oomycete Phytophthora infestans and is infamous for causing the Irish Potato Famine in the 1840s. Cops have become more vulnerable to diseases due to fluctuations in the growing environments caused by climate change. Variation in precipitation patterns and increasing temperatures can foster the growth and spread of diseases. Furthermore, agricultural intensification, with its emphasis on monocropping and high-density planting, creates an ideal environment for the pathogens. Due to the lack of genetic diversity in monocultures, once a pathogen infects a crop, it can quickly decimate entire fields. Mechanism of disease spread and innovative approaches of management of emerging diseases are discussed. By prioritizing research, implementing sustainable practices, and fostering global cooperation, it is possible to mitigate the impact of these pathogens on global crop production and ensure food security for future generations.
