Onion Builder – Onion Bulbing Specialty Fertilizer

Technical Specification:

Amino Acids ≥100g/L, Cu+Fe+Mn+Zn+B+Mo ≥20g/L

Benefits:

Specifically developed for the onion bulb bulbing stage. Uses highly active L-α free amino acids as the core energy carrier, scientifically compounded with multiple sources of chelated secondary/micronutrients and targeted bioactive components, systematically addressing core challenges during bulking like bulb splitting, malformation, insufficient dry matter accumulation, and sensitivity to environmental stress. Strongly activates the source-sink metabolic network through multiple amino acids, driving the efficient accumulation of photosynthetic products in the bulb. Chelated Calcium and Boron work synergistically to enhance scale cell wall toughness and orderly division of meristematic tissues, suppressing splitting at the root cause and ensuring firm, round bulbs. The innovatively added Polyglutamic Acid-Polypeptide composite module significantly improves rhizosphere microenvironment adaptability, inhibits colonization by Fusarium and purple blotch pathogens, while simultaneously enhancing physiological buffering capacity against alternating dry/heat conditions and saline stress. Ultimately achieves a synergistic leap in bulb bulking rate and quality/flavor, promoting improved skin smoothness and enrichment of flavor compounds (pyruvic acid, thioethers), achieving high yield and premium quality targets.

 Applicable Crops: Onion, Root and Tuber Crops

 Application Instructions:

Foliar Spray: Dilute 800-1000 times. Apply at 7-10 day intervals for 2-3 consecutive applications.
Fertigation/Drip Irrigation: 15-30L/ha

Cautions:

1.Avoid mixing with strongly acidic or alkaline fertilizers and pesticides, as this may affect product efficacy. If mixing with other products is intended, conduct a small-scale compatibility test first.

2.Reapplication at a reduced rate may be necessary if rainfall occurs within 4 hours of spraying.

Storage:

1.Store and transport in the original container. Keep sealed in a cool, dry place.

2.Store separately from food, drink, and feed. Keep out of reach of children and livestock.
