Pathogenic microbes have taken advantage of climate change to evolve virulence and spread plant diseases. Climate change significantly alters the virulence and dissemination of pathogenic microbes by rising temperatures, changing precipitation patterns, and increasing atmospheric carbon dioxide concentrations, consequently enhancing their survival and reproduction rates. Microbial pathogens may evolve to become more virulent in response to environmental changes, and virulent strains resistant to plant defenses may also evolve. Climate change may also alter plant-microbe interactions with plant helpful microbes that assist plant defenses, take up nutrients, and perform other functions like nitrogen fixation. Increased humidity, altered precipitation patterns, and other climate-related environmental stressors (such as drought or nutrient shortage) may encourage the persistence and spread of pathogens, including their reproductive and dispersal stages, and lower plant resistance and immunity. A multifaceted approach to managing climate change’s negative effects on plant health is crucial. To ensure sustainable agricultural production systems and food security in a changing climate, research on plant resilience and the interactions of pathogens with climate change will be essential.
