Paclobutrazol is a triazole type plant growth retardant which blocks gibberellin biosynthesis and are involved in reducing abscisic acid, ethylene and indole-3-acetic acid while increasing cytokinin levels. It promotes fruit set in the states of inhibited development . It is also known that it protect plants against abiotic stresses. 40kg/drum
