Description

Brassinolide is a highly active, naturally occurring plant growth regulator belonging to the brassinosteroid class of phytohormones. It is valued for its ability to significantly enhance crop stress tolerance, promote growth, and improve yield and quality at very low application rates. This makes it a critical component for advanced agricultural formulations, including biostimulants, foliar sprays, and seed treatments, targeting high-value crops in horticulture, viticulture, and broad-acre farming.

Application

• Enhancing plant resistance to abiotic stresses such as drought, salinity, heat, and cold.
• Promoting cell division and elongation to improve overall plant vigor and biomass.
• Increasing fruit set, size, and uniformity in fruit and vegetable crops.
• Improving photosynthetic efficiency and chlorophyll content for better crop yields.
• Used in seed treatment formulations to improve germination rates and seedling establishment.
• Formulated into foliar sprays and drip irrigation solutions for precision agriculture.
• An active ingredient in commercial plant growth regulators and advanced biostimulant products.
• Research and development of novel agrochemicals and plant physiology studies.
