Thidiazuron is widely used in agriculture as a plant growth regulator. It promotes cell division and is particularly effective in inducing the formation of callus in plant tissue culture. This chemical is instrumental in micropropagation, helping to produce large numbers of plants from a small amount of tissue.

In cotton farming, Thidiazuron is used as a defoliant. It aids in the shedding of leaves, which facilitates mechanical harvesting by reducing leaf interference. This application is crucial for improving the efficiency and quality of the cotton harvest.

Additionally, Thidiazuron is employed in the cultivation of certain fruits and ornamental plants to enhance bud break and improve the uniformity of flowering. Its ability to delay senescence also helps in extending the shelf life of cut flowers and leafy vegetables.

Overall, Thidiazuron plays a significant role in modern agricultural practices, contributing to increased productivity and quality in various crops and plant species.
