Aqueous extract from the germinated seeds of sweet Lupinus albus

The aqueous extract from the germinated seeds of sweet Lupinus albus is a natural bioactive substance widely utilized in modern agriculture as a plant biostimulant and immune system booster. Obtained from the sprouting seeds of the white lupine, this extract contains a complex mixture of signaling peptides, amino acids, and secondary metabolites that work together to enhance the metabolic processes of cultivated plants.

Its mechanism of action is primarily classified as an elicitor-based response. Upon application, the extract interacts with plant surface receptors, initiating a signaling cascade that triggers the systemic acquired resistance (SAR) pathway. This internal defense mechanism strengthens the plant's ability to ward off fungal infections and bacterial pathogens by thickening cellular walls and increasing the production of phytoalexins, without toxic side effects.

The extract is suitable for a wide range of crops, including cereals, vegetables, and fruit orchards. In agricultural practice, it is applied during various stages: seed treatment to improve germination energy and seedling vigor, and foliar spraying during active growth phases to mitigate abiotic stress caused by drought, frost, or salinity. Its ability to prime the plant's defense system makes it an effective tool for preventing yield losses.

Regarding application features, the extract is highly compatible with organic farming standards and integrated pest management (IPM) programs. It leaves no harmful residues and does not disrupt the balance of beneficial soil microorganisms or pollinators. Due to its natural composition, it can be easily tank-mixed with various micro-fertilizers, often acting as a surfactant and uptake enhancer that ensures better bioavailability of nutrients.

While the product is generally safe, growers should follow standard agricultural safety protocols, including wearing protective gear when handling concentrated solutions. It should be stored in a dry, cool place protected from direct sunlight to maintain the stability of the bioactive compounds. Implementing this extract in a regular agronomic schedule helps in achieving higher yields while simultaneously promoting sustainable and environmentally conscious farming practices.
