Advances in the Control of Plant Fungal Pathogens

Fungi are the main causative agents of plant diseases and are responsible for substantial and recurrent damage to agricultural systems. Their activity causes significant reductions in crop productivity and food quality, ultimately contributing to plant deterioration and economic losses. It is estimated that phytopathogenic fungi can compromise up to 30% of global agricultural production. To mitigate microbial deterioration, a wide range of control strategies have been employed, with chemical fungicides being one of the most widely used interventions. However, current approaches to fungal control are rapidly transforming owing to the growing prevalence of fungicide resistance, increasingly stringent regulatory frameworks governing chemical applications, and evolving market demands. Taken together, these factors impose new constraints and drive the development of more sustainable alternative options for effective food control. This review examines the diverse strategies used to control fungal diseases in plants, emphasizing advances in biocontrol agents and biofungicides, as well as emerging tools in the molecular biology, genomics, and biotechnology fields. The aim is to highlight recent developments and prospects that can be integrated into comprehensive disease-management approaches.
