Description

AREA OF INVENTION

[0001] The invention relates to horticultural plant propagators consisting of natural extracts and excipients that promote the formation of adventitious roots in cuttings. They are supplied as a ready-to-use liquid or as a concentrate with a defined pH value and defined storage conditions. BACKGROUND OF THE INVENTION

[0002] Willow extracts are traditional natural rooting aids because they contain indole-3-butyric acid (IBA) and salicylic acid, which promote root formation and plant defense response, respectively. However, homemade preparations differ in efficacy and stability compared to commercial IBA products. Coconut water and aloe vera gel are considered biostimulants for propagating cuttings. Studies have shown improved germination, callus formation, and root development compared to synthetic auxins in certain plant species. Honey and cinnamon have been investigated as antimicrobial additives to reduce cutting infections. Moringa leaf extract (MLE) is a recognized plant biostimulant containing cytokinins (e.g., zeatin), auxins, and antioxidants that improve growth and stress tolerance. However, rooting success depends on the auxin / cytokinin ratio.Standardized preparation and controlled pH can improve reproducibility across different plant species and batches. Packaging as a composition / set with preparation and application instructions is suitable, as substances and products are items requiring protection. SUMMARY OF THE INVENTION

[0003] The invention relates to a natural, multi-plant root promoter consisting of: a willow extract with endogenous IBA and salicylic acid; a moringa leaf extract as a biostimulant with cytokinins and antioxidants; aloe vera gel and coconut water as root promoters; an optional organic acid component (e.g., salicylic acid / acetylsalicylic acid dissolved in apple cider vinegar) for antimicrobial support; and optional antimicrobial additives (cinnamon extract / powder, honey). The pH is adjusted to 5.5–6.5, and the mixture is packaged for refrigerated storage. In certain embodiments, a defined amount of exogenous IBA (indole-3-butyric acid) is added to standardize the auxin level. The compositional ratios were selected from ranges recommended in horticultural literature to achieve reproducible rooting in a large number of cuttings.The product is supplied as a ready-to-use liquid or as a two-component set (auxin phase and biostimulant phase) with mixing instructions, quality controls (pH value, total phenol content) and expiry date information to ensure consistent propagation results. DETAILED DESCRIPTION

[0004] Component extracts: Willow extract is produced by soaking young willow twigs in water (hot or cold) and then filtering. The resulting solution contains natural IBA and salicylic acid. The soaking parameters are controlled to ensure reproducibility and are documented as a traditional source of rooting hormones. Moringa leaf extract is obtained by mixing the leaves with water (e.g., 3.3% w / v) and then filtering. It contains cytokinins (especially zeatin), auxins, gibberellins, and antioxidants, and acts as a biostimulant for growth and stress resistance when applied to plants or cuttings. However, a balanced auxin ratio is crucial for rooting. Aloe vera gel is pureed and filtered until it has a pourable consistency. Coconut water is used neat or diluted.Both act as natural biostimulants and have been shown to offer benefits in propagating various species from cuttings. In certain areas, such as germination and callus formation, they sometimes outperform synthetic auxins. Salicylic acid / aspirin additive: Salicylic acid or acetylsalicylic acid (aspirin) can be dissolved in a small amount of apple cider vinegar before dilution to provide antimicrobial and signaling benefits. Concentrations are controlled to avoid phytotoxicity and to complement the willow's own salicylates. Antimicrobial additives: Cinnamon (as powder or extract) and honey can be added as natural antimicrobials to reduce infection and rot at the cut surfaces. The dosage is adjusted to maintain a fluid consistency and avoid excessive viscosity.Auxin Standardization: To compensate for variations in natural auxin content, a defined amount of IBA can optionally be added to the composition to achieve a target auxin range suitable for the respective plant species. This enables reproducible results compared to literature data on natural and synthetic auxins. Formulation: The components are mixed under controlled stirring and at controlled temperature. The pH is adjusted to 5.5–6.5 for stability and tissue compatibility. The final volume is adjusted with distilled water. The product is then filtered to remove particles and stored refrigerated to maintain bioactivity. Dosage Form: The composition is available as a single solution in bottles for immediate use (dip / soak) or as a two-component set.This kit contains an auxin-rich and a biostimulating / antimicrobial phase, which are mixed before use to improve shelf life. The labels indicate immersion times depending on the plant species and provide safety instructions. Quality control: Batch quality control includes pH, conductivity, and optionally spectrophotometric parameters (e.g., total phenol content) to monitor extract consistency. Shelf life depends on adherence to cold chain requirements and visual clarity. Application: Cuttings are immersed or soaked for 5–60 seconds, depending on compatibility. The product promotes rooting in plant species that root easily to moderately well. For species that are difficult to root, a higher IBA concentration is recommended according to established horticultural practice.
