Lecithin

Lecithin acts as a natural biological fungicide, primarily used to protect crops against various fungal pathogens. Derived from vegetable oils like soy or sunflower, it is highly regarded in sustainable and organic agriculture for its safety profile and lack of toxicity toward pollinators and humans.

The mechanism of action of lecithin is predominantly physical. When applied to plant surfaces, it alters the permeability of fungal cell membranes, effectively disrupting the pathogen's development. Additionally, as an emulsifying agent, lecithin improves the coverage and adhesion of the spray solution, ensuring that active ingredients reach all parts of the leaf surface.

Lecithin is effectively used to control major diseases such as powdery mildew, late blight, scab, and botrytis. It is commonly applied on a wide range of horticultural crops, including vines, berries, and greenhouse vegetables, providing a protective barrier against fungal colonization and spore germination.

Application strategies require precision to maximize efficacy. As a contact fungicide, it is essential to ensure thorough coverage of the foliage, particularly the undersides of leaves. Regular, preventative applications are highly recommended, as they establish a continuous defense layer before severe infection pressures occur in the field.

• Environmentally friendly with no risk of toxic residues in the soil or produce.
• Can be used throughout the growing season due to its safety.
• Improves the performance of other tank-mixed biologicals through better wetting.
• Compatible with standard low-pressure spraying equipment.

Precautions for handling lecithin are minimal compared to synthetic chemicals, yet standard protective gear like gloves should be worn to avoid skin or eye irritation. The product should be stored in a cool, dry area away from direct sunlight to maintain the stability of the emulsion and ensure long-term shelf life.
