Thidiazuron solution is widely used in agriculture as a plant growth regulator. It promotes defoliation in cotton before harvest, helping to improve the efficiency of mechanical harvesting by reducing leaf interference. It is also used to enhance fruit thinning in orchards, ensuring better fruit size and quality by reducing overcrowding on trees. In tissue culture, Thidiazuron plays a key role in stimulating shoot formation and callus growth, making it valuable for rapid plant propagation. Its ability to influence cell division and differentiation makes it effective in forestry and horticulture for improving germination and seedling development.
