About Paclobutrazol Technical

Paclobutrazol (PBZ) is a plant growth regulator that inhibits the biosynthesis of gibberellins, plant hormones responsible for promoting growth. By suppressing gibberellin production, PBZ effectively reduces internodal elongation, resulting in shorter, sturdier plants with enhanced root systems. It also influences othe...

Ornamental Horticulture

PBZ is widely used in ornamental plant cultivation to control excessive growth, improve plant shape, and enhance flowering. ​

Fruit and Vegetable Production

Applied to various fruit and vegetable crops, PBZ promotes early fruiting, increases yield, and improves fruit quality by regulating plant growth. ​

Turf Management

In turfgrass management, PBZ reduces mowing frequency and enhances turf quality by controlling vertical growth. ​

Arboriculture

Arborists use PBZ to manage the growth of trees and shrubs, especially in urban environments, to reduce maintenance needs and improve structural integrity. ​

Cereal Crop Lodging Prevention

PBZ application in cereal crops like maize and wheat strengthens stems, reducing the risk of lodging and improving grain yield. ​

Storage

Store in tightly closed containers in a cool, ventilated area • Keep out of reach of children

Handling

Use personal protective equipment (PPE) • Maintain adequate ventilation • Do not eat, drink, or smoke while handling
