Bloom star (Paclobutrazol 23%) slows down the growth of mango trees by regulating plant hormones, resulting in more controlled and compact growth.
Its principal mode of action is the inhibition of gibberellin biosynthesis; hence inhibits rate of cell division
The compound is taken through stem tissue or roots and is translocated to the site of action in sub-apical meristems
Tree vigour is controlled by reducing the internodes lengths of new shoots and earlier formation of terminal buds. Fruit bud production, fruit color and harvest yield can also be favourably influenced
