Thiophanate-methyl is widely used as a fungicide in agriculture to protect crops from fungal diseases. It is effective against a broad spectrum of pathogens, including those causing powdery mildew, leaf spot, and blight in fruits, vegetables, and ornamental plants. The chemical is applied as a foliar spray or soil treatment, providing both preventive and curative action. It works by inhibiting fungal cell division, thereby stopping the growth and spread of the disease. Thiophanate-methyl is also used in post-harvest treatments to extend the shelf life of produce by preventing fungal decay. Its systemic nature allows it to be absorbed by plants, offering long-lasting protection. Additionally, it is utilized in turf management to maintain healthy grass in lawns and golf courses by controlling fungal infections.
