Kresoxim-methyl is widely used as a fungicide in agriculture to protect crops from fungal infections. It is particularly effective against a range of diseases such as powdery mildew, leaf spots, and rust in various plants, including cereals, fruits, and vegetables. The chemical works by inhibiting mitochondrial respiration in fungi, thereby preventing their growth and spread. It is often applied as a foliar spray, ensuring direct contact with the affected plant parts. Its systemic action allows it to be absorbed and distributed within the plant, providing long-lasting protection. Kresoxim-methyl is valued for its efficiency and relatively low environmental impact when used as directed.
