Boscalid is widely used as a fungicide in agriculture to control a broad spectrum of fungal diseases in crops. It is particularly effective against pathogens causing powdery mildew, gray mold, and various types of blights. Commonly applied to fruits, vegetables, field crops, and ornamentals, it protects plants both by preventing spore germination and by inhibiting fungal growth. Its systemic nature allows it to move within the plant, providing long-lasting protection even after rain or irrigation. Boscalid is often included in integrated pest management programs due to its favorable environmental profile and low impact on beneficial insects. It is also used in seed treatments to safeguard germinating seeds and young seedlings from soil-borne diseases.
