Description

Trinexapac-Ethyl CAS NO 104273-73-6 is a highly effective plant growth regulator belonging to the class of cyclohexanedione compounds. It functions as a gibberellin biosynthesis inhibitor, primarily used to control vegetative growth and improve stress tolerance in various crops. This product is essential for agricultural professionals and formulators seeking to enhance crop yield, quality, and lodging resistance. Its targeted action makes it a key component in modern, sustainable plant management programs.

Application

• Turfgrass Management: Suppresses vertical growth in golf courses, sports fields, and lawns to reduce mowing frequency and improve turf density.
• Cereal Crop Lodging Control: Applied to wheat, barley, and rye to shorten and strengthen stems, preventing lodging (falling over) and facilitating harvest.
• Rice Growth Regulation: Manages plant height and improves resistance to lodging in paddy rice, contributing to stable yields.
• Oilseed Rape (Canola) Management: Regulates growth to improve standability and pod development, potentially enhancing seed yield and quality.
• Sugarcane Ripening Aid: Used as part of a chemical ripening program to inhibit top growth and potentially increase sucrose concentration.
• Ornamental Plant Production: Controls excessive stretching in nursery stock and potted plants, resulting in more compact and marketable specimens.
• Professional Lawn Care Formulations: A key active ingredient in commercial liquid and granular products for landscape maintenance.
• Agricultural Chemical Intermediates: Serves as a technical-grade material for the synthesis of formulated end-use products (e.g., SC, EC, WG).
