What type of fabric should be treated with fungicide and mildewicide?

The correct answer pertains to organic fabric because it is typically more susceptible to mold and mildew growth compared to synthetic fabrics. Organic fabrics, such as cotton or linen, are derived from natural plant sources, which provide an ideal environment for mold and mildew to thrive, especially in humid or damp conditions.

The treatment with fungicide and mildewicide helps to protect these organic materials from deterioration and preserves their structural integrity and appearance. By applying these protective agents, you can extend the life of the fabric and maintain its functionality, especially in applications where it is exposed to moisture.

In contrast, synthetic fabrics like nylon and polyester are often treated during manufacturing to resist moisture and may not require additional fungicidal and mildewcidal treatments to the same extent. Therefore, while synthetic options have benefits, when it comes to treating with fungicides and mildew inhibitors, organic fabrics are the primary focus due to their increased vulnerability to such issues.
