I. Overview
Defoliant is a growth regulator that can promote plants to shed leaves in autumn, shorten the plant growth period, improve the efficiency of plant photosynthesis, and enhance the plant's resistance to stress and cold. The mechanism of action of defoliants is to regulate the level of endogenous hormones, age the leaves, and promote shedding. For plants that have been in a low temperature environment for a long time, the appropriate use of defoliants can also effectively promote their growth and development.

II. Correct method of using defoliants
1. Dosage
The dosage of defoliants should be adjusted according to different plant species and growth conditions. Generally speaking, the greater the dose of defoliant required by the plant, the higher the verticality of growth, and the lighter the color of the leaves, the greater the dose of defoliant used. At the same time, when the temperature is high, the dose adapted to the temperature can make the defoliant more effective.

2. Timing of use
Before the formal use of defoliants, necessary reserves or cultivation work should be carried out first. This will enable plants to reach the best state during the vigorous growth period, and after the defoliant is used, the plants can better adapt to environmental changes, which is beneficial to the growth and health of plants. Defoliants are generally applied in autumn, and the application time and interval for each plant species should be different. Generally speaking, the application time of defoliants should be when the plants form buds and begin to enter the peak of growth. Before using defoliants, necessary investigations and reserves should be carried out, and the correct use methods should be mastered to avoid adverse effects on plants.

3. Precautions
Before using defoliants, necessary reserves or treatment work should be carried out first. Generally speaking, this treatment work includes garbage removal, wilting and root structure treatment. In addition, the laws of plant growth and seasonal changes should be followed, and different regulators, doses and methods of use should be selected according to different climates, environments and plant species to achieve the best effect. In addition, before using defoliants, it should be ensured that the state of the plants is appropriate and they are in the best state of growth. If there is any discomfort, stop using it in time.

[Summary]
Defoliants are a growth regulator that can promote plants to shed leaves in autumn, improve plant photosynthesis efficiency, and enhance plant resistance to adversity and cold. However, to use defoliants for plant growth regulation, it is necessary to master the correct dosage, timing of use and precautions to achieve the best effect.
