Description

Paclobutrazol CAS NO 76738-62-0 is a highly effective plant growth regulator belonging to the triazole chemical class. Its primary value lies in its ability to control vegetative growth, promote flowering, and enhance stress tolerance in a wide range of crops and ornamental plants. This makes it an essential tool for commercial growers, horticulturists, and agricultural formulators seeking to improve yield, manage plant architecture, and optimize production efficiency.

Application

• Fruit Tree Management: Controlling excessive shoot growth and promoting fruit set in mango, apple, pear, and citrus orchards.
• Ornamental Horticulture: Producing compact, sturdy plants with enhanced flowering in potted flowers, bedding plants, and nursery stock.
• Turf Management: Suppressing vertical growth and reducing mowing frequency on golf courses, sports fields, and lawns.
• Agricultural Crop Regulation: Managing plant height and lodging resistance in cereal crops like rice and wheat under certain agronomic programs.
• Industrial Vegetation Control: Used in non-crop areas for managing growth of brush and certain tree species.
• Formulation Intermediate: Served as a key active ingredient for the manufacture of various agricultural chemical formulations, including soluble concentrates (SC) and wettable powders (WP).

Quality Control

Our Paclobutrazol is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. A comprehensive Certificate of Analysis (COA) documenting key parameters such as assay, moisture content, and impurity profiles is provided with each shipment to guarantee consistency and reliability for your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the original container is kept sealed to prevent absorption of atmospheric moisture, which can affect stability and handling properties.
