Paclobutrazol

Biological Activity

Paclobutrazol is a new, high-efficiency, low-toxicity plant growth regulator that can inhibit the production of gibberellin derivatives and reduce the division and elongation of plant cells. Paclobutrazol is easily absorbed by roots, stems, and leaves, and is conducted through the xylem of the plant. Paclobutrazol also has a bactericidal effect. Paclobutrazol has a wide range of activities on gramineous plants, which can make the plant stem internodes stout, reduce lodging and increase yield.
