BioWorks Sandrine Organic Copper Soap Fungicide Concentrate, 1 Gallon

Complete Coverage. Powerful Disease Suppression.

Sandrine is a liquid copper soap that provides broad-spectrum protection against a wide range of fungal and bacterial diseases. By combining soluble copper with fatty acids, Sandrine forms a true soap formulation that enhances leaf surface coverage while using less copper than traditional copper soaps. It's gentle enough for use on copper-sensitive crops and leaves no visible residue.

Sandrine delivers the best results when applied at the first sign of disease. The soap component, derived from fatty acids, evenly coats plant surfaces and disrupts pathogen cell membranes. This allows the copper to penetrate and interfere with the pathogen's enzyme systems, effectively stopping disease development. The result is uniform coverage and reliable control for healthier, more resilient plants.
