What is the primary purpose of plant growth regulators?

The primary purpose of plant growth regulators (PGRs) is to modify the growth patterns of plants, which often includes slowing their growth. This can be essential in various horticultural practices, such as controlling the height of ornamental plants, managing the timing of flowering, and promoting denser growth habits. By regulating growth, these substances help to improve the overall health of the plant, create desired aesthetic characteristics, and can also aid in pest and disease management by maintaining a more resilient plant structure. Other responses may touch on beneficial aspects of plant growth regulators, but their primary function in many applications is indeed to slow down growth, allowing for better control and management of plant development.
