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 other physiological processes, such as promoting flowering and improving stress tolerance.

PBZ is widely used in ornamental plant cultivation to control excessive growth, improve plant shape, and enhance flowering.
Applied to various fruit and vegetable crops, PBZ promotes early fruiting, increases yield, and improves fruit quality by regulating plant growth.
In turfgrass management, PBZ reduces mowing frequency and enhances turf quality by controlling vertical growth.
Arborists use PBZ to manage the growth of trees and shrubs, especially in urban environments, to reduce maintenance needs and improve structural integrity.
PBZ application in cereal crops like maize and wheat strengthens stems, reducing the risk of lodging and improving grain yield.
Store in tightly closed containers in a cool, ventilated area • Keep out of reach of children

Packaging Options: Available in various sizes, typically ranging from 100 g to bulk quantities for commercial use
Paclobutrazol is a plant growth regulator (PGR) used to control plant growth by inhibiting gibberellin biosynthesis. It is commonly used in horticulture, agriculture, and turf management to regulate plant height, improve root development, and enhance yield.
Paclobutrazol works by inhibiting the production of gibberellins, which are plant hormones that promote growth. By blocking their synthesis, it reduces cell elongation and increases root development, leading to shorter, sturdier plants.
Paclobutrazol is safe for a wide range of plants when applied according to recommended guidelines. However, it should be used carefully to avoid overuse, which may result in stunted growth or reduced flowering in some plant species.
The effects of Paclobutrazol are generally long-lasting. After application, it can remain effective for several weeks to months, depending on the plant species and environmental conditions.
