Naphthalene acetic acid (NAA) is an auxin plant regulator. It enters the plant body through leaves, tender epidermis and seeds, and is transported to the parts with vigorous growth (growth points, young organs, flowers or fruits) with nutrient flow, significantly promoting the tip development of the root system (rooting powder), inducing flowering, preventing falling flowers and fruits, forming seedless fruits, promoting early maturity, increasing production, etc. It can also enhance the plant's ability to resist drought, cold, disease, salt and alkali, and dry hot winds.

Indole-3-butyric acid (IBA) is a plant growth regulator that can promote plant growth and development, make plants more luxuriant and strong, and improve plant immunity and stress resistance.

Brassinolide (BRs) is an effective plant growth regulator used to alleviate pesticide damage. Brassinolide (BRs) can effectively help crops resume normal growth, quickly improve the quality of agricultural products and increase crop yields, especially in alleviating herbicide damage. It can accelerate the synthesis of amino acids in the body, make up for the amino acids lost due to pesticide damage, and meet the needs of crop growth, thereby alleviating pesticide damage.

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.
