Thidiazuron (TDZ) is a plant growth regulator used incotton defoliation,  facilitate harvesting
micropropagations to supplement media such as murashige and skoog medium.

Thidiazuron promotes plant organogenesis (shoot regeneration) and plant regeneration.
Thidiazuron (TDZ) enables the production of virus-free stock plants, speeds up
breeding, and provides new genotypes for the market.

Commercially, Thidiazuron contained plant growth regulators can be applied to plant leaves by spraying, after Thidiazuron is adsorbed by the leaves, it stimulates formation of an abscission layer between the plant stem and the leaf petioles, causing the dropping of entire green leaves. it is used very commonly for cotton defoliation in order to facilitate harvesting. sometimes, by adding some herbicides (for example: diuron) .
