Paclobutrazol (Bonzi, Friazole, Clipper) is a systemic triazole compound that functions uniquely as both a plant growth regulator (pgr) and fungicide. Paclobutrazol suppresses gibberellin biosynthesis to reduce shoot elongation and enhance root development, improving crop structure and yield. This Paclobutrazol SC formulation enables ease of drench application and consistent soil uptake across horticultural and fruit crops. Paclobutrazol generally used by agronomists and plantation managers to modulate plant architecture, promote early fruit set, enhance crop uniformity, & increase stress tolerance in fruit, ornamental and cereal systems.

Chemical Properties & Specifications
Eye Irritation (Cat. 2) Reproductive Toxicity (Suspected, Cat. 2) Aquatic Toxicity (Acute & Chronic, Cat. 1)
H319: Causes serious eye irritation H361d: Suspected of damaging unborn child H410: Very toxic to aquatic life with long-lasting effects
III (Slightly hazardous)
Applied as a soil drench around the tree trunk to regulate vegetative growth and induce uniform flowering in mango, apple, pomegranate, grapes, and citrus.
Used in ornamental plants, shrubs, and landscape trees to control height and improve longevity, especially beneath infrastructure and power lines.
In cereals and turf, it enhances stem strength, controls lodging, and provides stress resilience including drought and disease resistance
*Dual-Action Effect: Combines growth regulation with moderate antifungal activity *Long-Retained Soil Activity: Slow-release through root uptake, lasting seasons *Precision Application: Applied via soil drench enables low-drift and targeted uptake *Economic Dosing: Efficient at 15–40 mL/tree (for mature fruit), varies by crop's age *Stress Performance: Enhances drought resilience, shade tolerance, and lodging reduction with enhanced root growth
Store between 0–30 °C in dry, well-ventilated space, protected from sunlight.
Available in 100 mL to 5 L HDPE plastic containers or drums.
Minimum of 2 years when stored under recommended conditions Handling Note: Avoid freezing and maintain gentle agitation to preserve dispersion quality

It inhibits ent-kaurene oxidase in the gibberellin biosynthesis pathway, limiting cell elongation and directing growth to root systems.
Primarily fruit trees (e.g., apple, mango, grapes), ornamentals, and turf. Best results in mature orchards via soil drench application. Doses vary from 15 to 40 mL per tree depending on species and tree's age.
Apply as a soil drench around the base of the plant. Avoid irrigation for a few days for optimal absorption; mixing is not required due to SC format.
Use gloves and eyewear during handling. Avoid contact with eyes and pregnant individuals. Avoid contamination of aquatic ecosystems.
Effects on growth and flowering can persist several months to a year depending on crop and dose.
