About Paclobutrazol 23% SC

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 form...

Fruit Crops & Orchard Management

Applied as a soil drench around the tree trunk to regulate vegetative growth and induce uniform flowering in mango, apple, pomegranate, grapes, and citrus.

Ornamental & Landscape Use

Used in ornamental plants, shrubs, and landscape trees to control height and improve longevity, especially beneath infrastructure and power lines.

Cereal & Turf Regulation

In cereals and turf, it enhances stem strength, controls lodging, and provides stress resilience including drought and disease resistance

Speciality

*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

Storage Conditions

Store between 0–30 °C in dry, well-ventilated space, protected from sunlight.

Packaging Formats

Available in 100 mL to 5 L HDPE plastic containers or drums.

Shelf Life

Minimum of 2 years when stored under recommended conditions Handling Note: Avoid freezing and maintain gentle agitation to preserve dispersion quality
