Features of INDOLE-3-BUTYRIC ACID (IBA): INDOLE-3-BUTYRIC ACID (IBA) is an endogenous auxin that can promote cell division and cell growth, induce the formation of adventitious roots, increase fruit set, prevent fruit drop, and change female and male flowers Ratio etc. It can enter the plant body through the tender epidermis of leaves, branches, and seeds, and is transport to the active parts along with the nutrient flow.

Forchlorfenuron, also known as KT-30, CPPU, etc., is a plant growth regulator with furfurylaminopurine effect. It is also a synthetic furfurylaminopurine with the highest activity in promoting cell division. Its biological activity is about that of benzylaminopurine 10 times, it can promote crop growth, increase fruit setting rate, promote fruit expansion and preservation

Thidiazuron (TDZ) is a urea plant growth regulator. It can be use under high concentration conditions for cotton, processed tomatoes, peppers and other crops. After being absorbed by plant leaves, it can promote early leaf shedding, which is beneficial to mechanical harvesting. ; Use under low concentration conditions, it has cytokinin activity and can be used in apples, pears, peaches, cherries, watermelons, melons and other crops to increase fruit setting rate, promote fruit enlargement, and increase yield and quality.

Brassinolide (BR) is different from other plant growth regulators in its one-way targeting in promoting crop yield and improving quality. For example, it not only has the physiological functions of auxin and cytokinin, but also has the ability to increase photosynthesis and regulate nutrient distribution, promote the transport of carbohydrates from stems and leaves to grains, improve the crop's resistance to external adverse factors, and promote the growth of weak parts of the plant. Therefore, it has extremely wide usability and practicality.
