Syngenta Cultar

Cultar, containing Paclobutrazol is a systemic plant growth regulator. Its principal mode of action is the inhibition of gibberellins biosynthesis. 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 internode lengths of new shoots and earlier formation of terminal buds. Fruit bud production, fruit color and harvest yield can also be favorably influenced.
