Promote seed germination, root growth and sprouting; Promote photosynthesis in crops; Enhance the resistance of crops to adverse environments such as low temperatures, high temperatures and drought.

Regulators are a type of pesticide, just like insecticides and fungicides, they are also a classification of pesticides.

Plant growth regulators are substances that are artificially synthesized by imitating the chemical structure of plant hormones (or extracted from microorganisms) and possess the activity of plant hormones. They can show promoting or inhibitory effects on the growth and development of plants at relatively low concentrations. They enter the plant body and exert their effects by stimulating or inhibiting the speed or quantity of endogenous hormone transformation within the plant.

Plant growth regulators are widely used in agriculture, roughly in the following aspects: breaking the dormancy of seeds and primordia propagators and promoting the germination of seeds or tubers; Promote the growth of vegetative bodies; Promote the rooting of cuttings; Prevent steep growth, drooping branches and dwarfing of the plant type; Change gender; Control bolting and flowering; Prevent flower and fruit drop or promote thinning of flowers and fruits to increase the fruiting rate; Promote fruit development and ripening to form seedless fruits; Prevent aging, keep the product fresh and extend the storage period. It can be said that things that are difficult to achieve with cultivation techniques or methods can all be solved with plant growth regulators.
