Active ingredient	Paclobutrazol
Classification	Plant Growth Regulator / Agrochemical
Formulation	15%WP, 25%SC
Biochemistry	Inhibits gibberellin and sterol biosynthesis, and hence the rate of cell division.
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.
Usage	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.
Mammalian Toxicology	Oral: Acute oral LD50 for male rats 2000, female rats 1300, male mice 490, female mice 1200, guinea pigs 400-600, male rabbits 840, female rabbits 940 mg/kg. Skin and eye: Acute percutaneous LD50 for rats and rabbits >1000 mg/kg. Mild skin irritant; moderate eye irritant (rabbits). Not a skin sensitiser (guinea pigs).

Technical requirements for use:

1. This product should be applied at the stage of one leaf and one heart of rice seedlings, pay attention to spray evenly. 2. Pay attention to the dosage, if the spraying is excessive, it can be rescued by adding nitrogen fertilizer. 3. Do not apply the pesticide on a windy day or if it rains within 1 hour.

Product performance:

This product is a triazole plant growth regulator and an inhibitor of endogenous gibberellin synthesis. Obviously weaken the top growth advantage of rice seedlings and promote the growth of lateral buds (tillers). The appearance of the seedlings is short, stout, and tiller, and the leaves are dark green. The root system is well developed. Improve root respiration intensity; reduce the respiration intensity of the above-ground part and reduce leaf transpiration. Mainly use rice seedlings to control growth.
