Paclobutrazol 23% SC is a widely used Systemic Plant Growth Regulator (PGR) formulated as a Suspension Concentrate (SC) with 23% active ingredient.
Mode of Action: It functions by inhibiting the biosynthesis of gibberellins, which are plant hormones responsible for stem elongation and vegetative growth.
Key Effects: This inhibition leads to reduced vegetative growth (shorter, more compact plants), enhanced flowering and fruiting (by redirecting the plant's energy), and often improved stress tolerance (e.g., drought resistance) and root development.
Primary Use: It is extensively used in horticulture, particularly for fruit trees like mango, to manage tree vigor, promote uniform and early flowering, and ultimately increase yield and fruit quality. It's also used in other crops and ornamentals.
