Cycocel plant growth regulator provides excellent results in greenhouses and plant nurseries. It reduces stem elongation and promotes longer shelf life for poinsettias and other marketable plants. In addition, Cycocel contains an active wetting agent, saving you money on surfactants and adjuvants. It works on commercially grown plants in covered greenhouses and containerized ornamentals in uncovered areas. You can improve and induce flowering of bedding plants after one application. For greater management in the greenhouse, spray your plants with Cycocel plant growth regulator.


What Does a Plant Growth Regulator Do?

Plant growth regulators inhibit stem growth and extend a plant's shelf life. They contain certain chemical agents that not only reduce growth in a given season but also promote denser growth in the container or the flower bed. Regulators also produce crops with shorter internodes, stronger stems and greener, thicker leaves. Unlike some plant growth regulators, Cycocel includes a wetting agent for improved activity on the target plants.


How Cycocel Works

Cycocel contains chlormequat trimethylammonium chloride, a chemical that inhibits plant growth and increases density in the leaves. It's formulated to affect commercially greenhouse-grown ornamentals only, not field-grown ornamentals. However, it does produce expected results in container plants in uncovered production areas. Its wetting agent binds the active ingredient to the ornamentals and helps the regulator perform more efficiently after the application.


Where to Use Cycocel

Use Cycocel plant growth regulator in commercial greenhouses, shade houses and plant nurseries. These facilities should have covered spaces; otherwise, spraying Cycocel in windy conditions could create drift and cause serious damage to other plants. Use it to reduce plant growth on herbaceous and woody crops such as:

  • Ivy
  • Chrysanthemums
  • Easter lilies
  • Hollies
  • Hydrangeas
  • Potted roses
  • Rhododendrons
