Da-6 plant growth regulator

Da-6 is a high-energy plant growth regulator with broad-spectrum effects. It is primarily used to increase chlorophyll content, accelerate cell division, and enhance photosynthetic efficiency. In commercial scenarios, it is applied to field crops, fruits, and vegetables to improve yield and quality. Unlike other regulators, it is highly stable and can be mixed with various fertilizers and fungicides to synergistically improve nutrient absorption and disease resistance.

Buyers should look for Da-6 98% TC (Technical Concentrate) as the industry standard for raw material sourcing. Key indicators include a white or light yellow crystalline powder appearance and a solubility in water that leaves no residue. Ensure the product has a low moisture content (<0.5%) to prevent caking during long-term storage. For liquid formulations, verify the active ingredient concentration matches the labeling exactly to ensure application safety.

As a chemical pesticide/regulator, Da-6 must comply with FAO (Food and Agriculture Organization) standards. Buyers must verify the supplier's Pesticide Registration Certificate and Production License. For international trade, a Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch are mandatory. Ensure the product meets REACH regulations if exporting to the EU or EPA registration requirements for the US market.

One of the core advantages of Da-6 is its low-temperature resistance; it continues to function at temperatures where other regulators become inactive. It is non-toxic and leaves no residue, making it suitable for green and organic-standard agricultural production. It has a long-lasting effect (up to 20 days) and is highly safe, with a wide range of application concentrations that minimize the risk of phytotoxicity (plant damage) compared to NAA or GA3.

Always request a pre-shipment third-party inspection (such as SGS or BV) to verify the purity and chemical composition. Use secure payment terms like Letter of Credit (L/C) or trade assurance services provided by Made-in-China.com to protect your funds. Avoid suppliers who cannot provide a traceable batch number or those offering prices significantly below the market average, as this often indicates adulterated or low-purity products.

Focus on volume-based pricing tiers; typically, orders exceeding 500kg can secure a 10-15% discount. Negotiate for customized packaging (e.g., 1kg aluminum foil bags vs. 25kg drums) to reduce local repacking costs. Ask for free samples (50-100g) for lab testing before committing to a bulk purchase. Additionally, seek technical support guarantees, ensuring the supplier can provide guidance on formulation compatibility.

Da-6 is generally classified as non-hazardous for transport, but it must be kept in a cool, dry, and ventilated warehouse. Ensure the supplier uses moisture-proof and UV-shielded packaging to prevent degradation during sea freight. For shipping to specific regions, confirm the HS Code (typically 2922.49) and ensure all customs declaration documents clearly state the chemical name and intended agricultural use to avoid port delays.
