Key benefits
- Elite Drought & Cold Defense Acts as a powerful organic osmolyte, maintaining cell turgor and preventing dehydration during severe drought or frost.
- Rapid Recovery Trigger Speeds up recovery from herbicide damage, salinity shock, and transplant stress by protecting vital plant proteins.
- Pollination & Fruit Set Booster Highly concentrated in pollen grains; applications during flowering maximize pollen viability and fruit set.
Suggested dosage & application
- For Formulators & Manufacturers As a 99% ultra-pure crystalline amino acid, it is ideal for premium biostimulant lines. Solubility: 100% water-soluble; forms a crystal-clear, stable liquid blend. Compatibility: Highly compatible with NPKs, humic/fulvic acids, and seaweed extracts. Industrial Blending Rate: Add 1% to 5% by weight into final liquid or powder fertilizer formulations.
- Reference Field Application Rates Standard foliar dilution: 200 to 500 mg/L (ppm). Foliar Spray: Apply 0.5 to 1.0 kg/ha (Dilution: 1:1,000 to 1:1,500). Spray 2–3 days before expected frost, drought, or heat waves. Flowering/Fruit Set: Spray at early budding and full bloom to increase fruit set and reduce blossom drop. Root Drench/Drip: Apply 2.0 to 4.0 kg/ha to relieve root system salinity stress.
