Paclobutrazol is the leading gibberellin biosynthesis inhibitor for commercial fruit tree and ornamental crop management. By reducing endogenous gibberellin levels, it redirects plant resources from excessive vegetative growth toward reproductive development — improving flowering, fruit set, and harvest consistency in high-value orchard and plantation crops.
Mode of Action
Paclobutrazol blocks the three-step oxidation of ent-kaurene to ent-kaurenoic acid catalyzed by cytochrome P450 monooxygenases in the gibberellin biosynthetic pathway. This reduces active gibberellin (GA1) concentrations, shortening internodes, compacting canopies, and promoting the transition from vegetative to reproductive growth.
WP Formulation Benefits
- Versatile Application: Suitable for foliar spray, soil drench, and trunk injection from a single formulation
- Accurate Dosing: Fine powder enables precise weighing for individual-tree soil drench treatments
- Strong Root Uptake: WP suspension delivers effective concentration to the root zone for sustained action via soil drench
- Cost-Effective Production: Straightforward manufacturing process enables competitive OEM pricing
Application Methods
- Foliar Spray: 0.3–1.0 kg/ha for field crops, nursery stock, and young fruit trees — rapid uptake through leaf tissue for seasonal growth regulation
- Soil Drench: 0.5–2.0 g/tree applied to the root zone of mature fruit trees — delivers sustained uptake and multi-season effect with a single application
- Trunk Injection: Precision dosing for high-value orchard programs where uniform distribution and minimal environmental loss are required
Who It Is For
- Fruit tree brand owners seeking flowering induction and canopy management solutions
- PGR distributors supplying mango, apple, citrus and ornamental programs
- OEM clients needing specialized growth-regulator formulations with regional registration support
- Orchard management companies integrating PGR into precision horticulture programs

Frequently Asked Questions
How does paclobutrazol control vegetative growth?+
Paclobutrazol inhibits the oxidation of ent-kaurene to ent-kaurenoic acid in the gibberellin biosynthesis pathway, reducing endogenous gibberellin levels. This shortens internode length, reduces leaf expansion, and shifts the plant resource allocation from vegetative to reproductive development.
What application methods are available for paclobutrazol?+
Three primary methods: foliar spray (0.3–1.0 kg/ha for field crops and young trees), soil drench (0.5–2.0 g/tree for mature fruit trees, delivering sustained uptake through the root system), and trunk injection (for precision dosing in high-value orchard programs).
On which crops is paclobutrazol most commonly used?+
Mango (flowering induction and vegetative control), apple and pear (canopy management and vigor control), stone fruits, citrus, and ornamental plants. It is also used in rice and wheat for lodging reduction in certain regions.
What precautions should be taken with paclobutrazol applications?+
Avoid over-dosing, which can cause excessive growth stunting and reduced fruit size. Apply at the correct phenological stage — typically pre-flush for vegetative control or pre-bloom for flowering promotion. Soil drench effects persist longer than foliar; adjust rates accordingly.
What is the minimum order to customize a formulation?+
MOQ is 20+ tons per approved formulation, subject to raw material and packaging requirements tons for standard volume production, with pilot runs from 5 tons (custom formulation or new packaging) and 20+ tons (new formulation requires dedicated registration; registration adds 60–90 days) for custom packaging tooling.
How long do samples and production take?+
Samples are ready in 7–14 days; batch production completes in 25–35 days after confirmed PO and deposit.
Can I change colors, artwork and the logo?+
Yes — label design, color coding, logo placement, packaging and accessories are all customizable on every formulation platform. Share your logo and we produce a visual proof before production.
How is quality controlled before shipment?+
Every batch passes a 100-point production checklist and a HPLC purity · GC residue · stability test specification test before packing; batches exceeding specification limits are auto-rejected.
