Plant growth regulator
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.
Paclobutrazo, inhibit gibberellin biosynthesis,shorten stalks of crops, then lodging-resistance Mainly used on mango, low cost but high effect.

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.
