Plant Growth hormone Paclobutrazol 95%TC, 25%SC, 15%WP, 30% WP
Paclobutrazol is a plant growth retardant. 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. Paclobutrazol has also been shown to reduce frostsensitivity in plants.
Paclobutrazol is also used 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.

Application：
Shorten stalks of crops, then lodging-resistance
Inhibits the stem growth and breaks the apical dominance(inhibit the generation of Gibberellic acid);
Inhibits the intermode elongation, resists to lodging;
Improves the abilities of stress tolerance
Promotes the lateral bud growth
Enhances or inhibits the photosynthesis, depends on the concentration
Improves the respiration intensity of root, slows down the respiration of aboveground parts of crops.
