Cyazofamid is primarily used as a fungicide in agriculture to protect crops from various fungal diseases. It is particularly effective against oomycetes, which are responsible for diseases like downy mildew and late blight in plants such as grapes, potatoes, and vegetables. The chemical works by inhibiting mitochondrial respiration in the pathogens, preventing their growth and spread. Its application helps in maintaining crop health and yield, ensuring better quality produce. Farmers often apply it as a foliar spray, ensuring thorough coverage of the plant surfaces for maximum effectiveness. Due to its targeted action, it is considered a valuable tool in integrated pest management programs, reducing the need for broader-spectrum chemicals.
