[Chemical name] : (2RS,3RS)-1-(4-chlorophenyl)-4,4-dimethyl-2-(1
H-1,2,4-triazol-1-yl)pentan-3-ol
[CAS NO.] : 76738-62-0
[Use] : Paclobutrazol is a powerful, broad-spectrum triazole plant growth regulator (PGR) that inhibits gibberellin biosynthesis, reducing internodal stem growth and promoting thicker, more compact plants. It is widely used to manage growth in ornamental horticulture, turf, and fruit trees, often applied via soil drench or foliar spray to increase stress tolerance, improve flower/fruit set, and reduce pruning needs.
