The defoliation effect of thidiazuron is excellent, and the ripening effect is not as good as that of ethephon. It is greatly restricted by weather conditions, but it will still produce good results when used rationally. Thidiazuron is a urea plant growth regulator mainly used for cotton defoliation and ripening. On the other hand, it has extremely strong cell division activity. Its ability to induce plant cell division and callus is more than a thousand times higher than ordinary cytokinins. It is also an excellent cytokinin, promoting fruit enlargement and delaying plant aging. , enhance its stress resistance, promote photosynthesis of plants, increase crop yields, and improve product quality.

Mechanism of action:

Thidiazuron is a urea plant growth regulator. It is absorbed through cotton leaves and affects the three main plant hormones in the plant – ethylene, auxin and cytokinin, promoting the formation of natural separation between the stems, leaves and petioles of cotton. layer, causing cotton to drop leaves. It has extremely strong biological activity, and its ability to induce plant cell division and tissue calligraphy is hundreds of times higher than that of ordinary cytokinins.

Precautions for use

1. After using thidiazuron, it can cause the cotton plant itself to produce abscisic acid and ethylene, causing an abscission layer to form between the petiole and the cotton plant, causing the cotton leaves to fall off on their own.

2. Thidiazuron can quickly transfer nutrients to the young cotton bolls in the upper part of the cotton plant while the leaves are still green, and the cotton plant will not die, achieving multi-effects of ripening, defoliation, increased yield, and increased quality. .

3. Thidiazuron can make cotton ripen earlier, cotton bolls will bloom relatively early and concentrated, and increase the proportion of flowers before frost. Cotton does not pinch the shell. It does not shed lint or flowers, increases fiber length and improves clothing content, which is beneficial to mechanical and manual harvesting.

4. The efficacy of thidiazuron lasts for a long time, and the leaves will fall off when they are green, completely solving the problem of “withering but not falling”, reducing the pollution of leaves to machine-picked cotton, and improving the efficiency of mechanized cotton picking operations. Quality and efficiency.

5. Thidiazuron can also reduce the damage of later pests.

6. Thidiazuron has a control effect on weeds in cotton fields (except nightshade). Judging from the effect, it is still a herbicide.
