Folcisteine NATCA 99% TC
Plant Growth Stimulant & Stress Resistance Additive
Folcisteine NATCA 99% TC (N-Acetyl-Thiazolidine-4-Carboxylic Acid) is a high-purity metabolic biostimulant powder for crop stress defense and yield performance. Inside the plant it metabolizes into cysteine and thiol compounds that scavenge reactive oxygen species during drought, frost and salinity stress, and works in synergy with folic acid to stimulate cell division, leaf greening and fruit set. For direct field use: foliar spray at 2–5 ppm (approx. 2–5 g per 1,000 L of water), seed treatment or root drenching at 1–3 ppm, applied 2–3 times at vegetative stage, pre-flowering and early fruit setting. For formulators: add 2.5–5 g per 1,000 L in liquid biostimulant blends, or 5–10 g per metric ton in dry NPK or amino acid formulations. Packed in 25 kg drums with custom OEM packaging. MOQ 100 kg; standard lead time approximately 10 working days to Shanghai port; batch COA with every shipment.

Suggested dosage & application
For Field Application (End-Users)
Foliar Spraying: dilute to 2–5 ppm active (approx. 2–5 g of product per 1,000 L water) and spray 2–3 times at vegetative stage, pre-flowering and early fruit set.
Seed Treatment / Root Drenching: use 1–3 ppm (approx. 1–3 g per 1,000 L water).
Abiotic Stress Protection: apply before or during heatwaves, dry periods or saline irrigation events at the same 2–5 ppm foliar rate.
For Formulators
Liquid biostimulant blends: add 2.5–5 g per 1,000 L. Dry NPK / amino acid formulations: add 5–10 g per metric ton. Often combined with folic acid or amino acids for synergistic effects.

Frequently asked questions
01What is the main action mechanism of Folcisteine NATCA 99% TC in agriculture?
Folcisteine NATCA (N-Acetyl-Thiazolidine-4-Carboxylic Acid) acts as a high-efficiency metabolic precursor. Inside the plant, it metabolizes into cysteine and thiol compounds, actively scavenging reactive oxygen species (ROS) during abiotic stress (drought, frost, or salinity). Furthermore, when combined with folic acid, it directly stimulates plant cell division, leaf greening, and fruit set rate.
02What is the recommended usage rate of Folcisteine NATCA 99% TC for foliar sprays and formulation blending?
Because Folcisteine NATCA 99% TC is highly bioactive, the effective operational dosage is very low: End-User Foliar Application: Dilute to 2–5 ppm (approx. 2–5 grams per 1,000 liters of water) during early vegetative, pre-flowering, or stress recovery periods. For Formulators: Add 2.5–5 grams per 1,000 Liters in liquid biostimulants or 5–10 grams per Metric Ton in dry NPK/Amino Acid formulations to create premium high-value stress-resistance products.
03How is the solubility and compatibility of Folcisteine NATCA with other agrochemicals?
Folcisteine NATCA 99% TC features excellent water solubility (approx. 12.5g/100ml at 25°C) and stability in common liquid tank mixes. It is widely compatible with amino acid liquid fertilizers, seaweed extracts, humic acids, and standard pesticides. However, we recommend avoiding direct blending with strong alkaline chemicals to prevent degradation.
04Do you offer OEM processing, custom packaging, and free sample testing from your Folcisteine factory?
Yes. As a professional Folcisteine manufacturer and certified Folcisteine factory, we offer full OEM Folcisteine NATCA 99% TC services, including tailored blend concentrations, private label branding, and custom bag/drum packaging options. We also provide free samples (100g) for global formulators to perform laboratory testing prior to commercial bulk orders.
05What are the primary differences between Folcisteine (NATCA/AATC) and ordinary PGRs like ATONIK or DA-6?
While traditional plant growth regulators like ATONIK or DA-6 focus heavily on cell expansion and hormonal signaling, Folcisteine NATCA uniquely integrates metabolic cell protection with biostimulation. It directly increases internal enzymatic defense mechanisms against environmental hazards while boosting flower/fruit retention, making it safer and less prone to causing phytotoxicity under extreme stress conditions.
06What is the MOQ, packaging and lead time for Folcisteine NATCA 99% TC?
Folcisteine NATCA 99% TC is packed in standard export packaging 25kg drum with OEM customization available. MOQ is 100 kg; lead time is about 10 working days to Shanghai port, and every shipment includes a batch COA.
07How should Folcisteine NATCA 99% TC powder be stored?
Store sealed in a cool, dry place below 25 °C, away from direct sunlight and moisture. Shelf life is 24 months from the manufacturing date; keep the packaging tightly closed after use.
