Product Description

Paclobutrazol is a systemic plant growth regulator widely used in agriculture, horticulture, and turf management. It works by inhibiting the biosynthesis of gibberellins, thereby suppressing excessive vegetative growth, promoting stronger root systems, and enhancing the plant’s stress resistance.

It is commonly applied to rice, fruit trees, vegetables, ornamental plants, and turf to improve crop quality, increase yield, and reduce lodging risk.

Product Features

Effective Growth Control – Inhibits shoot elongation, making plants shorter and stronger.

Root Development – Enhances root growth, improving water and nutrient uptake.

Stress Resistance – Improves plant tolerance to drought, cold, and disease.

Better Quality & Yield – Promotes uniform flowering and fruit set, improving overall crop quality.

Long-lasting Effect – Provides extended activity in soil, reducing frequent applications.

Application

Rice: Applied after transplanting to reduce plant height and prevent lodging.

Fruit Trees (e.g., mango, citrus, apple): Controls tree vigor, promotes flowering, and improves fruit set.

Ornamental Plants & Flowers: Keeps plants compact, prevents overgrowth, and enhances appearance.

Turf & Lawns: Reduces mowing frequency and maintains uniform turf growth.

Precautions

Always follow the label instructions and recommended dosage.

Avoid excessive application to prevent over-suppression of plant growth.

On fruit trees, apply at the right stage to avoid negative effects on flower bud differentiation.

Observe safety intervals before harvest to ensure food safety.

Store in a cool, dry place away from direct sunlight and high temperature.
