Glycine Betaine (Anhydrous) 98% Crystalline Powder
Plant Osmoprotectant & Biostimulant — 100% Water-Soluble, for Foliar Spray and Fertigation
Nova-Agri Biotech supplies Glycine Betaine (Anhydrous) 98% Crystalline Powder (CAS 107-43-7, C5H11NO2) — a 100% water-soluble plant osmoprotectant and biostimulant used in foliar sprays, fertigation and biostimulant formulations to mitigate heat, drought and salinity stress in crops. Derived through high-purity chemical processing, this versatile natural osmolyte rapidly accumulates within plant cell sap to regulate cellular water balance, safeguard photosynthetic machinery, and prevent yield-limiting heatwave stress, drought damage, and soil salinity. Supplied as white crystalline powder with an assay of ≥98%, pH 5.0–7.0, moisture 0.4%, lead ≤10 ppm and arsenic ≤2 ppm, verified by a batch COA for every shipment. Packed in 25 kg bags (custom OEM packaging available), with a batch COA for every shipment. Standard lead time: approximately 10 working days to Shanghai port after payment confirmation. MOQ: 500 kg. As a leading Glycine Betaine manufacturer in China, we offer direct bulk supply, OEM custom packaging, and full technical documentation to support global agrochemical distributors and formulators. Specifically engineered for modern agricultural formulators, liquid fertilizer producers, and commercial growers, our Glycine Betaine 98% powder serves as a powerful active ingredient in foliar sprays and fertigation blends — delivering exceptional efficacy in fruit cracking prevention, sunburn mitigation, and overall pre-harvest fruit quality enhancement for high-value horticultural crops. For field use, apply 1.0–3.0 kg/ha as a foliar spray (dilute 1:500–1:1,000), 2.0–5.0 kg/ha via drip irrigation or fertigation, or 1.0–2.0 g/kg for seed treatment. For formulators, add 5–15 kg per 1,000 L when enriching liquid biostimulant blends.

Key benefits
- Drought, Heat & Salt Stress Tolerance via Ultra-Efficient Cellular Osmoregulation: Rapidly accumulates in plant cytoplasm without disrupting enzyme activity, maintaining cell turgor during severe heatwaves, drought, and high soil salinity.
- Fruit Cracking & Sunburn Mitigation: Preserves skin elasticity in rain-sensitive high-value fruits (cherries, table grapes, avocados, blueberries, citrus), dramatically reducing epidermal splitting and solar damage.
- Photosynthesis Protection Under Thermal Stress: Stabilizes Photosystem II (PSII) complexes and Rubisco enzymes, enabling crops to maintain carbon fixation even when temperatures exceed 35℃.
- 100% Water Soluble & Clean Dissolution: Fast-dissolving crystalline powder leaving zero residue, fully compatible with automated fertigation, micro-sprinklers, and agricultural drone nozzles.
- Salinity & Sodium Risk Relief: Restores cell water balance in high-EC environments, helping plants continue absorbing essential nutrients (K+, Ca2+) despite saline irrigation water.
- Factory Direct Bulk Sourcing: Supplied directly from Glycine Betaine manufacturer, offering custom private-label packaging (25kg bags/boxes) and registration technical dossiers.
Suggested dosage & application
For Formulators & Fertilizer Manufacturers (Industrial Blending):
- Enriching Liquid Biostimulant Formulations: Add 5.0 kg – 15.0 kg of Glycine Betaine 98% powder per 1,000 Liters of finished liquid (0.5% – 1.5% w/v) to create premium "Heatwave & Drought Recovery" blends.
- Water-Soluble NPK & Calcium Powder Blends: Incorporate 10.0 kg – 30.0 kg per Metric Ton (1.0% – 3.0% w/w). Synergizes with calcium and boron to maximize cell wall elasticity against fruit cracking.
- Foliar Anti-Cracking Concentrates: Blend 20.0 kg – 50.0 kg per 1,000 Liters (2.0% – 5.0% w/v) for specialized pre-harvest fruit sprays diluted at 1:500 to 1:1,000.
- OEM & Custom Processing: We support custom moisture tolerances, custom bag printing, and bulk OEM supply for global agrochemical brands.
For Commercial Field Application (End-Users & Growers):
- Foliar Spraying: Apply 1.0–3.0 kg/ha (diluted 1:500 to 1:1,000 in water; approx. 100–200 g per 100 L water). Apply 24–48 hours prior to expected heatwaves, or every 10–14 days during fruit expansion and pre-harvest windows.
- Drip Irrigation / Fertigation: Apply 2.0–5.0 kg/ha per application during acute drought periods or early root initiation.
- Seed Priming / Treatment: Use 1.0–2.0 g per kg of seeds to boost germination rates in saline or cold soils.

Frequently asked questions
01How does Glycine Betaine 98% powder function as a plant osmoprotectant?
Glycine Betaine 98% is an organic quaternary ammonium compound. When absorbed by foliage or roots, it accumulates within plant cell sap to regulate osmotic balance during environmental stress (drought, extreme heat, or salinity). It prevents cellular water loss and maintains turgor pressure without interfering with essential metabolic processes.
02How does Glycine Betaine prevent fruit cracking and splitting before harvest?
Fruit cracking occurs when rapid water uptake causes internal pulp swelling that exceeds skin elasticity. Glycine Betaine regulates epidermal cell turgor and membrane flexibility. When combined with calcium sprays, it stabilizes cell structures and drastically reduces skin splitting in cherries, grapes, citrus, and avocados after sudden rain events.
03What is the difference between Glycine Betaine and standard amino acid biostimulants?
Traditional amino acid hydrolysates provide diverse amino acid building blocks for general plant nutrition and protein synthesis. In contrast, Glycine Betaine 98% acts specifically as a targeted osmoprotectant and cellular shield, accumulating directly in cell sap to protect hydration status and photosynthetic enzymes during acute stress.
04Is Glycine Betaine (Anhydrous) 98% powder compatible with calcium nitrate and tank mixes?
Yes. Glycine Betaine 98% exhibits excellent physical and chemical stability. It is 100% soluble and fully compatible with calcium nitrate, chelated trace elements, seaweed extracts, and neutral crop protection products in tank mixes.
05Do you supply free laboratory samples and OEM packaging from your factory?
Yes. As a direct Glycine Betaine manufacturer in China, we supply 100g–500g free laboratory samples for quality audits and trial formulations. We also offer OEM Glycine Betaine packaging options with custom branding for international agricultural distributors. MOQ: 500 kg for standard orders.
06What is the difference between betaine anhydrous and betaine hydrochloride?
Betaine anhydrous is the free-base form with a near-neutral pH (5.0–7.0 in solution), which makes it the preferred grade for foliar sprays, fertigation and liquid biostimulant formulations — it does not shift tank-mix pH. Betaine hydrochloride is an acidic salt used mainly in animal feed. Nova-Agri supplies the anhydrous form with an assay of ≥98% and moisture of ≤0.4%.
07Do you provide a Certificate of Analysis (COA) with each shipment?
Yes. Every shipment is accompanied by a batch Certificate of Analysis issued by our in-house QC laboratory, covering assay, moisture, pH, heavy metals (lead and arsenic) and solubility. A sample COA is available on request through the inquiry form or direct message.
08What is the CAS number and molecular formula of glycine betaine?
Glycine betaine (anhydrous) has CAS number 107-43-7, molecular formula C5H11NO2 and a molecular weight of 117.15 g/mol.
09How should glycine betaine powder be stored?
Store sealed in a cool, dry place below 25°C, away from direct sunlight and humidity. The anhydrous powder is hygroscopic, so keep packaging tightly closed after each use. Shelf life: 24 months from the date of manufacture when stored as recommended.
10What is the MOQ, packaging and lead time for Glycine Betaine (Anhydrous) 98% powder?
Glycine Betaine (Anhydrous) 98% powder is packed in standard export packaging 25kg bag with OEM customization available. MOQ is 500 kg; lead time is about 10 working days to Shanghai port, and every shipment includes a batch COA.
