Paclobutrazole 40% SC

Paclobutrazole 40% SC is a high-concentration Plant Growth Regulator (PGR).

Here is a breakdown of what that means:

What is Paclobutrazol 40% SC?

• Active Ingredient: Paclobutrazol (40% concentration).

• Formulation: SC stands for Suspension Concentrate, which is a stable suspension of the active ingredient in a liquid, designed for dilution in water before application.

• Function: Paclobutrazol is a synthetic PGR that works by inhibiting the biosynthesis of gibberellins, which are plant hormones primarily responsible for cell elongation and stem growth.

Primary Effects and Benefits

By suppressing the production of gibberellins, Paclobutrazol redirects the plant's energy and resources. This results in several beneficial effects:

• Controls Vegetative Growth: Reduces excessive shoot and stem elongation, leading to shorter, more compact, and sturdier plants.

• Promotes Flowering and Fruiting: By reducing vegetative growth, the plant's energy is channeled towards reproductive organs, leading to:

  • Earlier and enhanced flowering.

  • Increased fruit set and yield.

  • Improved fruit quality (e.g., better color and size).

• Improves Plant Structure: Leads to shorter internodes, stronger branches, and better root development.

• Increases Stress Tolerance: Enhances the plant's resistance to environmental stressors like drought.

Common Uses and Application

Paclobutrazol 40% SC is used on a variety of crops, including:

• Fruit Trees: Mango is a particularly common target, where it is used to regulate the flowering cycle.

• Other Fruits: Pears, peaches, citrus, grapes, etc.

• Vegetables and Cereals.

• Ornamental Plants and Turfgrass to manage height and promote a compact look.

Application Methods typically include:

• Soil Drench/Collar Drench: Applying the diluted solution to the soil or around the base of the trunk. This is often preferred for long-term control, especially in fruit trees like mango.

• Foliar Spray: Spraying the diluted solution directly onto the leaves.

It is crucial to follow the manufacturer's recommended dosage and application timing for your specific crop to achieve the desired results and avoid phytotoxicity.
