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.

Physical and chemical properties of forchlorfenuron (KT-30). Forchlorfenuron is one of the main components in coconut juice. The original drug is a white solid powder, insoluble in water, and easily soluble in organic solvents such as acetone and ethanol

As a plant growth regulator, 2,4-D can promote cell division, prevent flowers and fruits from falling, increase fruit setting rate, promote fruit enlargement, improve fruit quality, increase yield, and make crops mature earlier and prolong the shelf life of fruits.
