PBZ 15%WP Plant Growth Hormone


15%WP paclobutrazol hormone






Paclobutrazol (PBZ) is a plant growth retardant and triazole fungicide.


It is a known antagonist of the plant hormone gibberellin.


It acts by inhibiting gibberellin biosynthesis, reducing internodial growth to give stouter stems, increasing root growth, causing early


fruitset and increasing seedset in plants such as tomato and pepper. 


PBZ has also been shown to reduce frost sensitivity in plants.


Moreover, paclobutrazol can be used as a chemical approach for reducing the risk of lodging in cereal crops.


PBZ is used by arborists to reduce shoot growth and has been shown to have additional positive effects on trees and shrubs.


Among those are improved resistance to drought stress, darker green leaves, higher resistance against fungi and bacteria, and


enhanced development of roots. Cambial growth, as well as shoot growth, has been shown to be reduced in some tree species.


PBZ is normally applied to the soil to be taken up by the roots and transported via the xylem to the upper parts of the plant.


Foliar application is mostly ineffective. Seeds can be soaked with PBZ to reduce seedling growth.

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. Uses 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 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.Phytotoxicity Non-phytotoxic, though it intensifies greening. Some spotting has been noted on periwinkle foliage at higher temperatures.
