Plant growth regulator
Organic compounds, either natural or synthetic, that modify plant growth processes such as stem elongation, germination, or flowering.

Plant growth regulators (PGRs) are essential tools for managing crop development, increasing yield uniformity, and enhancing tolerance to environmental stress. Growers use them to control plant height, stimulate rooting, or improve the shelf life of harvested produce.
Application timing is critical, usually occurring during specific developmental stages like seed treatment, flowering, or periods of rapid vegetative growth. Proper selection of the hormone type, such as auxins or gibberellins, ensures the desired physiological response.
Common mistakes include applying the product under unfavorable weather conditions or exceeding the manufacturer's suggested dose, which can stunt growth or cause plant deformation. Always ensure compatibility if mixing with other agrochemicals to avoid reduced efficacy.
