Plant Growth Regulators: What Buyers Should Know
Plant growth regulators (PGRs) are natural or synthetic compounds that steer plant development, including gibberellins, cytokinins, auxins, and brassinolides, to improve fruit set, size, rooting, and stress tolerance. Buyers source PGRs from China for high-purity technical grades and cost-effective formulations.
The key specifications are active-ingredient purity, formulation type, application rate, and registration status. Precise dosing matters because PGRs are active at very low concentrations. The curated suppliers below are screened against these criteria.

7 Checks Before Choosing a Plant Growth Regulators Supplier
1. Active ingredient
Confirm the exact PGR, its purity, and the technical-grade source.
2. Purity
High-purity technical grades (90%+) ensure reliable low-dose performance.
3. Formulation
Match soluble powder, liquid, or tablet form to your application method.
4. Dosage
Follow precise rates; PGRs are active at parts-per-million levels.
5. Registration
Verify product registration in the destination country before import.
6. Stability
Request shelf-life and storage-condition data for the formulation.
7. Documentation
Obtain COA, MSDS, and batch test reports with every shipment.
Frequently Asked Questions
What are plant growth regulators?
PGRs are natural or synthetic compounds that control plant processes such as flowering, fruit set, rooting, and stress response.
What is gibberellic acid used for?
Gibberellic acid (GA3) promotes stem elongation, fruit setting, seed germination, and larger fruit in crops such as grapes and citrus.
How much plant growth regulator should I apply?
PGRs are applied at very low concentrations, often parts per million; always follow the label and crop-specific recommendations.
What is the MOQ for plant growth regulators from China?
Technical grade may start at a few kilograms and formulated products at several hundred kilograms; see each supplier profile.
