Growth Regulators – What are they? Where are they used?

Growth Regulators are substances that function in plant growth and are normally active at very low concentrations. Among these, we can differentiate those produced by the plant and those that are of synthetic origin. Those that the plant forms naturally are called phytohormones or plant hormones.

Growth regulators are used for many purposes. They have the peculiarity that sometimes the same active ingredient offers several responses according to the moment of application and the concentration used. It also depends on the climate and how it is grown plays an important role. For this reason studies should be done in each region for several seasons.

Growth regulators are typically used to:

  • Thin fruit
  • Promote or increase the return of flowering
  • Promote more even and earlier maturation
  • reduce flowering
  • Improve fruit quality
  • enhance color
  • Reduce russeting and cracking of the fruits
  • delay maturity
  • Improve conservation
  • Increase the emission of side branches
  • Alter the format of the fruits
  • Reduce fruit drop before harvest


Most Growth Regulators are plant hormones called Phytohormones, among which are:

  • Auxins
  • Gibberellins
  • Ethylene
  • Cytokinins
  • Abscisic Acid


Grupo Fagro puts at your disposal both conventional and organic Growth Regulators, below, we present a brief introduction to these products.

Farmagib Nzn is a hormonal product designed to stimulate the development of plants, formulated with a high content of gibberellic acid and enriched with elements that act in synergy with this hormone: Nitrogen, Potassium and Zinc. The proper formulation quickly activates the growth of axillary buds, and also helps to overcome periods of environmental stress in the early stages of development. The hormonal mix plus nutrients, allows the effect in stimulating growth to be balanced.

Impulssor® is a high-tech product, designed to regulate and stimulate plant growth, through a balanced combination of growth regulators, nutrients, amino acids and vitamins, all of great importance in the physiological processes and metabolism of plants. . All its components are found in an assimilable form by the leaves and other organs of the plant.

Proroot® growth regulator designed to induce and stimulate root growth and stem thickening.

Its formulation is based on a balanced mixture of “rooting” hormones, macronutrients and fulvic acids, which are easily absorbed and assimilated both by foliar or root. They act in stages of rooting in transplant crops, beginning of flowering and fruit development, where it is necessary mainly to store and transport energy (ATP), regulating the activity of different intracellular compounds, and thus promote a better metabolism to the plant.

Raizorg is a Biofertilizer that in its formulation has specific bacteria that are installed in the rhizosphere of the plant immediately after its application, there, through its metabolic activity, they produce phytohormones that stimulate the production of primary and absorbent roots. Raizorg beneficial bacteria are also capable of fixing atmospheric nitrogen, solubilizing phosphorus and reducing metallic elements such as iron, so that in interaction with the roots they exert nutritional effects and stimulate plant growth.
