Impact of Climate Change on Plant Diseases

Climate change is profoundly altering the dynamics of plant diseases, with significant implications for global agriculture and ecosystem stability. This review explores how rising temperatures, shifts in precipitation patterns, and elevated atmospheric CO2 levels influence the incidence, distribution, and severity of plant diseases based on recent studies. Global temperature rise expands the geographic range of pathogens, including fungi, bacteria, viruses and oomycetes, while changes in moisture availability creates favorable conditions for both drought tolerant and water-dependent pathogens. Elevated CO2 may further affect plant-pathogen interactions by altering plant growth and resistance mechanisms. Additionally, climate-induced phenological shifts are leading to changes in the timing and frequency of disease outbreaks. Therefore, understanding these complex plant-pathogen interactions are essential for developing adaptive management strategies, importantly, breeding of climate-resilient crops, disease forecasting models, and integrated pest management practices. Proactive efforts are critical to mitigate the increasing risks of plant diseases with the rapidly changing climate, globally.
