Paclobutrazol 95%TC
Paclobutrazol 95% TC is high purity white crystalline technical material. It is a widely used triazole plant growth regulator, which can inhibit vegetative growth, shorten internodes, dwarf plants, strengthen stalks and prevent lodging. It effectively promotes flower bud differentiation, increases fruit setting rate, improves crop yield and enhances stress resistance. Widely used in fruit trees, cereals, vegetables and ornamental crops, stable chemical property, easy to formulate into EC, SC, WP and other finished preparations.

| Applications | 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. |
