Fungal Pathogens in Crop Agriculture: Emerging Challenges and Advancements in Management

Abstract

Fungal pathogens threaten global agricultural systems, leading to considerable crop loss and endangering food security. This review examines the many variables that have led to the spread of these infections, such as globalization, climate change, and increased agricultural methods that spread virulent and novel fungal strains. We investigate the intricate interactions between fungal pathogens and host plants, emphasizing the molecular mechanisms fungi employ, such as effector protein secretion, to subvert plant defenses. Biotrophic and necrotrophic fungi exemplify this relationship by relying on living host cells, causing substantial damage to key crops like wheat, with estimated global losses. The critical factors impacting the persistence and spread of fungal diseases include the effects of global trade, fungicide resistance, and environmental changes caused by climate change. Genetic resistance breeding, integrated pest management, and novel biocontrol techniques are some of the effective management options necessary to reduce the harmful consequences of fungal diseases. Fungal diseases can affect the safety and quality of food and lower crop yield. Developing successful control methods requires an understanding of these virus’s processes of infection, how they spread out, and the conditions that promote their growth. Conclusively, a multidisciplinary approach that integrates cutting-edge research with sustainable farming methods is necessary to tackle the problems of fungal infections. We can build resilient crop systems and protect global food security against fungus threats in the future by improving our understanding of fungal pathogen dynamics and host interactions.
