B-Nine Plant Growth Regulator

Water Soluble Granules

B-Nine reduces stature in ornamental plants by reducing internode length. When applied to plant foliage, it is absorbed into the leaf and moves within the plant to growing points to reduce internode elongation through inhibiting gibberellin synthesis. Additional B-Nine benefits include a more aesthetically pleasing, compact plant with deeper green color that is more resistant to breaking during shipping.

B-Nine may be used on ornamental plants grown in commercial or research greenhouses, shadehouses, and nurseries. Containerized plants labeled for use by B-Nine are but not limited to: Azaleas, Bedding Plants/ Flowering Plants, Plugs and Liners, Chrysanthemums, Foliage Plants, Gardenias, Hydrangeas and Poinsettias.

Rate of use: Rates range from 1000-7500 PPM (refer to the product label for specific rates). Spray should be directed at the leaves and stems just to the point of run-off. Application volume should be one gallon per 200 sq. ft. of coverage.

Active ingredient: 85% Daminozide

A-Rest Plant Growth Regulator - 1 Quart Atrimmec Plant Growth Regulator - 1 Qt

A-Rest Plant Growth Regulator


A-Rest is a plant growth regulator which is used on container grown bedding plants, flowers and foliage plants. A-Rest produces a plant that is more compact by inhibiting gibberellin biosynthesis, which results in shorter stem length. This helps growers produce high quality plants that are more compact, uniform in height, darker in color, more able to withstand shipping, require less water, and best of all, more attractive to the consumer.

Rate of use: The amount of A-Rest required for an optimum growth response depends upon pot size, stage of growth, method of application, season and varietal response. Please see label for dilution guidelines.

Active ingredient: 0.0264% Ancymidol

Atrimmec Plant Growth Regulator

is a systemic plant growth regulator (PGR) that works by blocking the plant hormones that stimulate growth. Atrimmec applied as a foliar spray interrupts apical shoot elongation, so one application with one trimming can last the entire season. Spraying shrubs, hedges, trees, and groundcovers reduces trimming and pruning labor by 50% or more, and improves the appearance of landscape ornamentals by promoting lateral branching. This gives plants a denser, fuller look. Hedges and shrubs that show irregular shapes, including damage from pests and weather, can fill in lushly, even on the old wood.

Atrimmec is labeled for bark banding and soil drench applications to reduce nuisance fruit and flower formation. Bark banding application is a quick, efficient and effective procedure accomplished by spraying the trunk of the targeted tree from a height of 4.5' to 5' to the soil surface. A single application of Atrimmec two to four weeks prior to early bud formation (pinhead size or smaller buds) can prevent undesired fruit for the season on certain landscape trees.

  • Spray-apply to retard growth of hedges, shrubs, trees, and groundcovers
  • Reduces trimming, pruning and cleanup maintenance by 50% or more
  • In many areas, one trimming and treatment controls growth all season long
  • Keeps plants looking trimmed longer
  • Promotes branching; forms a fuller, more compact, uniform shape
  • Groundcovers establish sooner, producing denser cover without encroaching on driveways, walks, and walls
  • Reduces nuisance fruits on landscape plants with bark banding and drench applications

Use: 1-5 fluid ounces per gallon, depending on species treated
