Captan solution is widely used as a fungicide in agriculture to protect a variety of crops from fungal diseases. It is applied to fruits, vegetables, and ornamental plants to prevent infections such as apple scab, brown rot, and powdery mildew. The solution is typically sprayed onto the foliage or soil, creating a protective barrier that inhibits fungal growth. Additionally, it is used as a seed treatment to safeguard seeds and seedlings from soil-borne pathogens during germination and early growth stages. In horticulture, it helps maintain the health of plants in nurseries and greenhouses. Captan solution is also employed in post-harvest applications to extend the shelf life of produce by preventing fungal decay during storage and transportation. Its effectiveness and broad-spectrum activity make it a valuable tool in integrated pest management programs.
