Controlling plant growth and development is essential to produce high-quality plants according to schedule and height specifications. Best practice requires that the cultural and physical methods of growth control be considered first, rather than any chemical application. However, these technologies alone may not be enough, and it is often necessary to integrate culture and chemical growth control into any production plan.
Chemical plant growth regulators (PGR) can produce rapid and precise plant responses, so they can be used actively and passively when arranging crops or blocking crops to respond to sudden changes in demand or non-seasonal effects of weather.
PGR can be used for:
PGR provides a range of business benefits, including:
However, there are concerns related to the use of PGR:
The main PGRs currently authorized and used for ornamental plants in the UK include: methylammonium chloride (Stabilan 750), daminozide (B-Nine SG, Dazide Enhance and Stature) and paclobutrazol (Bonzi and Pirouette).
To expand the range of PGRs available to growers, AHDB-funded trials evaluated potential alternative active ingredients for bedding and poinsettia (AHDB projects PO 019a and 019b). The tested products include: Canopy (original hexanedione calcium fortress), Moddus/Primo Maxx II (ethyl triformate), Regalis (original hexanedione-calcium) and Terpal (ethephon and strong).
Temperature, light, nutrition, irrigation, and contact are all factors that can be modified or used as methods to control plant growth.
Cultural and physical methods of growth control
Chemical plant growth regulators have different modes of action by inhibiting natural plant growth hormones, and understanding the active ingredients will help to get the most benefit from various products.
Chemical plant growth regulator-active ingredient
The application of chemical plant growth regulators (PGR) should be carried out at the appropriate growth stage and through recommended methods to achieve the desired effect.
Chemical Plant Growth Regulator-Application
Potential adverse effects of PGR application include yellowing of leaves, delayed plant growth, delayed flowering, and petal bleaching, all of which can have a negative impact on the final plant quality.
Potential adverse effects of the application of plant growth regulators
Other chemicals such as plant protection products and fertilizers can also affect plant growth and should be considered in any PGR plan.
