Application and Dosage of Tdz Thidiazuron:

Tdz Thidiazuron is typically applied as a foliar spray when cotton plants have reached the desired stage of boll maturity. The application timing is critical to ensure maximum efficacy and minimize any adverse effects on yield or fiber quality. It is recommended to apply TDZ under favorable weather conditions, avoiding periods of excessive heat or drought stress.

The dosage of TDZ can vary depending on factors such as local growing conditions, cotton variety, and application method. Generally, a concentration of 50-200 grams of TDZ per hectare is recommended for effective defoliation. It is important to follow manufacturer guidelines and local agricultural recommendations to determine the precise dosage tailored to specific field conditions.

Mode of Action:

Once applied, TDZ is absorbed through the leaves and translocated within the plant. Inside the cotton plant, TDZ disrupts the synthesis and distribution of auxins, which are crucial plant hormones responsible for growth and development regulation. By inhibiting auxin transport, TDZ promotes ethylene production within the leaves, leading to senescence and eventual abscission of foliage.
