Application

Mode of action:

• Paclobutrazol is a plant growth regulator taken up into the xylem through the leaves, stems or roots, and translocated to growing sub-apical meristems.

• Paclobutrazol produces more compact plants and enhances flowering and fruiting.

Uses of Paclobutrazol:

• Paclobutrazol is used on fruit trees to inhibit vegetative growth and to improve fruit set;

• on pot-grown ornamentals and flower crops 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.

Phytotoxicity of Paclobutrazol:

• Non-phytotoxic, though it intensifies greening.

• Some spotting has been noted on periwinkle foliage at higher temperatures.
