Paclobutrazol

Type: Plant Growth Regulator

Mode of Action: Inhibiting the gibberellin biosynthesis

Common Product Names: Piccolo

What is it?

Paclobutrazol is a synthetic compound belonging to the triazole family. It is typically applied to the soil or foliage of plants and is absorbed either through the roots or leaves. Once absorbed, it moves systemically throughout the plant to exert its growth-regulating effects. Paclobutrazol is particularly popular in ornamental horticulture, fruit tree management, and turfgrass maintenance due to its ability to control plant size, enhance flowering, and improve overall plant health. Results from Paclobutrazol applications can be seen within a few weeks, depending on the plant species and environmental conditions.

Paclobutrazol can be applied as a soil drench, foliar spray, or trunk injection, depending on the specific needs of the crop and the desired outcomes. The timing of application varies:

  • Soil Drench: Usually applied at planting or during early stages of growth for best results.
  • Foliar Spray: Typically applied before flowering to promote compact growth and enhance flowering.
  • Trunk Injection: Used in trees to manage growth and improve fruiting.

How does it work?

Paclobutrazol's primary function is to inhibit the synthesis of gibberellins, which are crucial for plant growth and development. By reducing gibberellin levels, Paclobutrazol decreases internodal elongation, resulting in shorter, more compact plants. Enhanced root development by reallocating resources that would otherwise go towards shoot growth. Promotes flowering and fruiting by stabilizing plant metabolism. Provides improves plant resistance to environmental stresses such as drought and salinity.

Benefits

  • Enhanced Plant Structure: Produces shorter, sturdier plants less prone to lodging or breaking.
  • Improved Flowering: Increases the number and quality of flowers, making it ideal for ornamental plants.
  • Better Fruit Set: Encourages more uniform and abundant fruit production in fruit trees.
  • Stress Resistance: Enhances plant resilience to various environmental stresses.
  • Resource Efficiency: Reduces the need for frequent pruning or trimming, saving time and labor.
