Plant Growth Regulators (PGRs) are compounds used to influence specific physiological processes involved in plant growth and development.
Depending on the active ingredient, crop and application, PGRs can be used to regulate processes associated with vegetative growth, rooting, flowering, fruit development, ripening and other stages of crop development.
GSP Crop Science offers plant growth regulator solutions designed to support specific crop management requirements when used according to approved recommendations.
Unlike conventional crop protection products that primarily target insects, weeds or diseases, Plant Growth Regulators work by influencing physiological processes within the plant.
Plants naturally regulate their development through signalling compounds commonly referred to as plant hormones. PGR products are used to influence particular growth or developmental responses depending on their chemistry, concentration, timing and crop.
PGRs may be used to influence plant height, shoot development and overall vegetative growth depending on the crop and active ingredient.
Certain plant growth regulators can influence processes associated with rooting and early plant development.
Specific PGRs may help regulate flowering-related processes when applied at the appropriate crop stage.
Depending on the product and crop, PGRs can influence physiological processes associated with fruit development and crop quality.
Certain PGRs may be used to influence developmental processes associated with crop maturity and ripening.
Note: These are general functions of the PGR category and should not be presented as claims for every GSP product. Product-specific benefits must follow the approved label.
The effectiveness of a PGR depends on more than the product itself. Crop, growth stage, application timing, concentration and environmental conditions can influence the plant response.
Plant Growth Regulators are particularly dependent on application timing and crop growth stage.
The response to a PGR can vary according tothe active ingredient, concentration, crop variety, physiological stage and growing conditions. Following the approved recommendation is therefore essential to achieving the intended response.
Plant Growth Regulators work through specific physiological processes, making product selection and application precision especially important. GSP's wider crop-protection capabilities are supported by in-house R&D and manufacturing infrastructure across technical-grade active ingredients and formulations.

Plant Growth Regulators should be used only for their approved crop, purpose, concentration, dosage and application stage.
Always follow the approved product label and recommended application instructions. Avoid assuming that a PGR suitable for one crop, variety or developmental stage will produce the same response in another.
