Product Description



Paclobutrazol 15% WP plant growth regulatorPaclobutrazol WP in fruit tree vegetable

Paclobutrazol Biochemistry
Inhibits gibberellin biosynthesis by inhibition of the conversion of ent-kaurene to ent-kaurenoic acid, and inhibits sterol biosynthesis by inhibition of demethylation; hence inhibits the rate of cell division.


Paclobutrazol Mode of action
Plant growth regulator taken up into the xylem through the leaves, stems or roots, and translocated to growing sub-apical meristems. Produces more compact plants and enhances flowering and fruiting.


Paclobutrazol Applications
Used on fruit trees to inhibit vegetative growth and to improve fruit set; on pot-grown ornamentals and flower crops (e.g. chrysanthemums, begonias, freesias, poinsettias and bulbs) to inhibit growth; on rice to increase tillering, reduce lodging and increase yield; on turf to retard growth; and on grass seed crops and oilseed rape to reduce height and prevent lodging. To be applied as a foliar spray, as a soil drench, or by trunk injection. Has some fungicidal activity against mildew and rusts. Rates of application vary widely, depending on area of use, application method, application timing, size of crop, and cultivation method.
