B-Nine
Product Overview
B-Nine® WSG plant growth regulator shortens the stature of ornamental plants by decreasing internode length. When applied to foliage, it is absorbed into the leaves and translocated to growing points where it inhibits gibberellin synthesis, resulting in a shorter and more compact plant.
Key Benefits
- Applications of B-Nine produce more compact, visually appealing plants with a darker green color and improve resistance to breakage during shipping.
- Daminozide, the active ingredient in B-Nine, has the lowest activity among PGRs, requiring relatively higher concentrations for growth regulation. This allows for greater application flexibility and a more controlled growth response.
- B-Nine is notably safe with few documented incidences of phytotoxicity or over-stunting.
- 12-hour reentry interval (REI).
