Advantages of Plant Growth Regulators
Promote or inhibit growth and yield: Plant growth regulators (PGRs) can increase or decrease growth rate and fruiting rate by regulating cell division and elongation. Growth regulation can help owners and managers reduce maintenance or speed up plant growth.
Uniformity: Using PGRs can help achieve uniform plant growth. This is especially useful for thickening shrubs used for screens and privacy. Gentle pruning and treating shrubs with PGRs can promote tight growth, which reduces the possibility of excessive new shoot growth.
Reduce lodging: Lodging is when a plant bends or breaks due to weak stems. Plant growth regulators (PGRs) can strengthen plant stems and reduce the risk of lodging, especially for tall, fast-growing shrubs.
Slow down senescence: Senescence is the natural aging and degeneration process of plant tissues. Some PGRs can slow down senescence and extend the productive life of plants.
Promote rooting: PGRs can stimulate root growth and development, which is beneficial for the growth of new plants and the regeneration of damaged roots. Improved root development can increase nutrient absorption and improve the overall health of the plant.
Enhanced stress tolerance: PGRs can help plants tolerate stress conditions such as extreme temperatures, drought, or high salt levels. They can enhance a plant's ability to cope with these stresses by promoting the synthesis of protective compounds and activating stress response pathways.
Improved fruit quality: PGRs can affect the quality of fruits and vegetables by improving characteristics such as fruit size, color, shape, flavor, and shelf life. They can also reduce fruit drop and increase fruit set, producing a more marketable product.
Flowering regulation: Plant growth regulators can control the timing and duration of flowering, which helps commercial growers target specific market windows or control flowering of ornamental plants for landscaping or exhibition purposes.

Application of Plant Growth Regulators

Agriculture:
Crop Improvement: PGRs can be used to enhance plant growth and improve yields in crops like cotton, where they can reduce stem elongation and lodging (falling over).
Fruit Development: PGRs can be applied to promote fruit development, including increasing fruit size, color, and ripening.
Seed Dormancy: Some PGRs, like abscisic acid, can be used to inhibit seed germination, allowing for longer storage of seeds.
Stress Tolerance: PGRs can help plants tolerate environmental stressors like drought, disease, and nutrient deficiencies.

Methods exist for applying PGRs
Foliar Spray Method
Foliar spray application of plant growth regulators (PGRs) is another means of applying them, providing fast absorption into the foliage for quick results. It is typically applied using a backpack sprayer.
To apply a foliar spray, mix PGR at its recommended concentration and use a sprayer to evenly spread it across the plant’s leaves. The amount used will be determined by the type of plant it is and its size. This must be done on a calm day to reduce drift and ensure it reaches the intended target.
Soil Drench
A soil drench is an easy and highly effective way of applying plant growth regulators (PGRs). It involves directly applying PGR solutions into the soil surrounding plants. Then, their root systems absorb these growth regulators and distribute them throughout their system.
Soil Injection
Soil injection is another popular PGR application technique. This process involves injecting PGR solution directly into the soil nearer its root zone for easy absorption by plants. It works particularly well when treating larger, well-established trees or shrubs, allowing deeper root systems to access PGR solutions.
To perform a soil injection, use an injection tool to create holes at the base of trees or shrubs, depending on their size and species. After creating holes around their bases, PGR solution should be directly injected into these holes using an injection gun.
