Plant Growth Regulators for New Zealand Farming
Plant Growth Regulators (PGRs) are specialised products that influence natural plant processes to improve growth, root development, nutrient uptake and overall plant performance.
In New Zealand farming systems, plant growth regulators are commonly used to stimulate pasture and crop growth during periods when temperatures, sunlight or soil conditions limit production. When used correctly, they can help fill feed deficits, improve nitrogen efficiency and increase dry matter production.
At Vernado, we offer a range of proven growth regulator products including Gibberellic Acid, Triacontanol and surfactant technologies designed specifically for New Zealand pasture and cropping systems.
Whether you are managing a dairy farm, sheep and beef operation, deer unit, maize crop or specialist forage system, plant growth regulators can be a valuable tool for increasing productivity and improving return on fertiliser investment.
What Are Plant Growth Regulators?
Plant Growth Regulators are naturally occurring or applied compounds that influence plant growth and development.
Plants naturally produce hormones that regulate:
Cell division
Leaf expansion
Root development
Stem elongation
Nutrient uptake
Photosynthesis
Stress tolerance
Applied plant growth regulators work by supporting or enhancing these natural processes, helping plants achieve faster and more efficient growth under challenging conditions. Gibberellins are among the natural hormones that regulate cell elongation and growth.
Why Combine Growth Regulators with Liquid Nitrogen?
One of the most effective strategies is combining plant growth regulators with foliar nitrogen applications.
Nitrogen provides the building blocks for growth, while plant growth regulators help the plant utilise those nutrients more effectively.
Potential benefits include:
Improved nitrogen efficiency
Faster growth response
Increased dry matter production
Reduced reliance on high nitrogen rates
Greater return on fertiliser investment
This combination is particularly valuable during autumn, winter and early spring when pasture demand often exceeds supply. Vernado promotes combining Liquid N with Gibberellic Acid and Triacontanol to improve growth and nitrogen efficiency.
Frequently Asked Questions
What is the best time to apply Gibberellic Acid?
Typically after grazing during autumn, winter and early spring when pasture is actively growing but limited by cooler temperatures.
How quickly will I see results?
Many farmers observe visible growth responses within 7–21 days depending on temperature, moisture and pasture conditions.
Can Gibberellic Acid be mixed with Liquid Nitrogen?
Yes. It is commonly used alongside liquid nitrogen programmes to improve overall growth response.
Does Triacontanol replace fertiliser?
No. Triacontanol enhances plant performance but does not replace essential nutrients. It works best as part of an integrated fertility programme.
Which pasture species respond best?
Most ryegrass-based pastures respond well when actively growing and moisture is adequate.
