PGRs, or Plant Growth Regulators, are specific types of agricultural products used at different stages during the development of plants throughout their lifecycle. There are many PGR types/products available today and farmers use them in modern agriculture to enhance the performance and uniformity of all crops.
Farming today uses PGRs throughout the growing cycle and includes some of the most well-known classifications of Plant Growth Regulators in the agricultural world, including auxins, gibberellins, cytokinins, ethylene, and abscisic acid. These classifications define how a plant growth regulator affects/impacts plants, e.g. root growth, long stems, flowering, ripening, and stress management.
Plant growth regulators are not like other fertilizers; rather than simply supplying nutrients to plants, many of the functions of traditional fertilizer occur at a hormonal level. Plant growth regulators have the potential to create improved yield/quality/resiliency for plants even when used at a lower rate than most other fertilizers.
Better understanding PGR names/meanings/scientific classifications/commercial product names enables farmers to select the correct type of Agriculture-PGR, which helps farmers produce stronger crops, produce a greater yield at the time of harvest, and promote the long-term success of sustainable agriculture
Understanding PGR Names: What They Are and Why They Matter
Similar to how every variety of millet has its individual name and nutritional significance; each PGR also has its own unique name describing the plant growth regulator (PGR) ‘s function, physical characteristics, or trade name. Understanding PGR names is essential for any user (farmer, researcher, agri-business), because they aid in correctly applying PGRs to achieve compliance and optimal performance.
Users identify each PGR’s active ingredient by looking up the active ingredient’s name in a scientific publication, a PGR fertilizer label, or on the product packaging.
What Do PGR Names Mean in Agriculture and Research?
When addressing the use of plant growth regulators (PGR) within an agricultural or research context, one can use several different names including:
- Chemicals such as Gibberellic Acid (GA₃)
- Common names such as Auxin and Cytokinin
- Trade Names (brand specific)
- Abbreviations used in scientific research
Each type of name serves a different function. Scientists usually use the chemical name and/or an abbreviated name while many farmers will identify commercial names printed on PGR fertilizer labels.
Why Accurate PGR Naming Is Important
Correctly identifying the plant growth regulator (PGR) name helps to avoid misuse, excessive application or confusion between different products with similar functions.
If you misinterpret the PGR name you will apply the incorrect product and potentially hinder the growth and/or yield of your crop.
How PGR Names Affect Data, Trade, and Compliance
Standards for all names of plant growth regulators (PGRs) have significant implications for global regulatory compliance, international trade and agriculture-related documentation.
In terms of trade and compliance:
- Accurate identification of active ingredients is required by regulatory agencies
- Correct documentation of the use of plant growth regulators is needed to export into other countries
- Common naming standards will ensure tracking of all data accurately.
In comparison of test results and data concerning crop performance within the field and the laboratory, consistently named plant growth regulators will be used to establish a basis for comparison.
Types of PGR Names and Their Applications
Like most millet crops are named based on their type and location; Plant Growth Regulators also have names that relate to their scientific classification, type of application and function. When used in Agriculture these names provide farmers, researchers and regulatory agencies the ability to accurately identify the specific Plant Growth Regulator and its intended use.
The ability to recognize the various types of Plant Growth Regulator names is essential for selecting the appropriate product, using them properly and complying with regulations, especially with respect to applying or purchasing PGR fertilizer.
PGR Names Used for Plant Growth Regulators
When growing crops, the term PGR typically refers to the main growing hormone (plant growth regulator) that is used to control plant growth.
The use of specific PGR names will allow producers to identify the correct amount to use at the proper time of the year.
PGR Names in Plant Genetic Resource Management
There is also the abbreviation PGR in the Agricultural world for Plant Genetic Resources (PGR) where they refer to Germplex's (variety of varieties) i.e., an accession of germplasm or breeding materials.
Over the managing genetic resources of plant material PGR can be used as:
- To identify crops and plants that are a distinct variety or line of breeding.
- To be used in plant seed banks and research institutions.
- To increase the establishment and maintenance of documentation of crop species introducing
- To facilitate crop improvement and development.
Although they share the same abbreviation, PGR fertilizer for the purpose of the growth regulation of plants and PGR from the perspective of genetic resources will be used for entirely separate purposes. By continuing to clearly define both of these terms, the confusion between the two can be minimized.
Functional vs Scientific PGR Naming Approaches
PGR names can be classified based on their usage context—functional (practical use) or scientific (chemical identification).
Importance of Standardized PGR Naming in Agriculture
In order to prevent confusion, all varieties of millet are given a unique identification number; likewise standardizing the name of a PGR allows for effective communication between farmers, researchers, and regulators, thereby providing an accurate and safe method of application and improving the efficiency of their work.
When standardization of names does not occur, different interpretations become possible. This may lead to errors in application; regulatory problems resulting from incorrect labeling; and/or poor yield due to misapplication of a product.
Role of Naming in Plant Breeding and Crop Improvement
Accurate nomenclature for plant genetic resources (PGR) is essential when dealing with plant breeding and research, as naming PGR clearly allows for the documentation of the tests, tracking of the results, and comparison of the performance of crops
Why is naming important for a breeding program?
- To ensure that there is a precise identification of active growth regulators
- To support the reproducibility of experimental data
- To prevent confusion between similar substances
- To standardize the publication of research findings and extension guides
As an example of clarity in communication and recommendations in the field, differentiating between GA₃ and other gibberellins will enhance clarity in scientific communication.
Avoiding Confusion in PGR Fertilizer Records
Valid and Consistent PGR's Name are Very Important in Farm Records, Product Labels and Compliance Documentation.
The Benefits of Using Standardized Naming When Managing PGR Fertilizer Will Be:
- Make it easier to track applied products accurately.
- Record dosage and timing of PGR applications more clearly.
- Reduce the chances of applying PGR products in duplicate or incorrectly.
- Aid with auditing/ensuring compliance with regulations.
International Guidelines for PGR Name Consistency
Worldwide, agricultural regulators and researchers use commonly accepted naming conventions for growth hormones and growth regulators.
The purpose of internationally accepted naming conventions is to:
- Provide consistent labeling on the human product.
- Allow for the interchange of products globally.
- Be able to monitor for residues and fully comply with laws.
- Encourage the proper use of growth hormones and growth regulators.
In establishing a consistent naming convention, from the perspective of the manufacturer and the farmer, PGR names can be used consistently throughout the globe, both commercially and for the purpose of research.
Common Challenges in Assigning and Managing PGR Names
Like the confusion between various types of millet that have similar sounding names can make it difficult to identify them in a commercial, research or agricultural environment, there are also instances where similar/same sounding PGR names have resulted in errant use. Given the widespread use of PGRs in agriculture and research, accurate identification is very important. If plant growth regulator fertilizer naming systems are not properly managed, incorrect application of fertilizers could occur; regulatory problems can arise, and historically inaccurate data could be produced.
By identifying common challenges associated with using PGRs, all stakeholders are able to establish and maintain clarity and compliance.
Duplicate and Conflicting PGR Names
One significant challenge facing agriculture is that there are various names given to the same active ingredient.
Causes of duplication include:
- Multiple trade names for one compound
- Differences in naming practices from region to region
- Inconsistent use of abbreviations
- Confusion between functional and scientific names.
As an example, the same active ingredient in plant growth regulators could be presented to farmers under several types of names:
- A chemical name (i.e., a scientific name)
- A common hormone name
- A product-specific commercial name
In the absence of a standard system to track this duplication, duplicate product names may result in a farmer applying two products with the same active ingredient without realizing they were applying the same active ingredient.
Misidentification and Data Errors
Where there are misidentifications of PGR names; data inconsistencies will occur, and incorrect field practices will take place as a result of these misidentifications.
Misidentifications have various risks including:
- Incorrect dosage calculation
- Applying incorrect dose of PGR fertilizers, at the wrong growth stage
- Results from research trials will be inaccurate, and
- Poor compliance with export/residue laws.
Solutions for Resolving Naming Conflicts
Standardized systems and careful records are necessary to reduce potential confusion related to plants.
There are many effective solutions that agricultural professionals will want to consider, including:
- Providing internationally accepted chemical names along with trade names;
- Keeping digital farm logs for PGR fertilizer applications;
- Checking for active ingredients before purchase;
- Training staff about the differences between common names and scientific names; and
- Following regulatory guidelines for labeling and reporting.
Consistent naming practices can provide agricultural professionals with the means to use plant growth regulators accurately and reliably, thereby reducing the risk of expensive errors.
Best Practices for Creating Clear and Reliable PGR Names
Agreements are important for consistent use of crop science-specific plant names. Each millet variety has its own unique name that is recognizable; therefore, similarly with PGR naming conventions, each plant growth regulator should be given a clear, consistent, and meaningful name to aid in reducing potential confusion concerning their use in agricultural and research applications. Since plant growth regulators will be used for the production of crops, applied in scientific research and sold in commercial commerce, it is necessary to have effective naming systems to promote accurate and safe communications about PGR fertilizer products.
The establishment of effective naming practices will provide for an environment that encourages improvement of transparency, compliance with regulations, and increased farm operating efficiency.
Guidelines for Naming Plant Growth Regulators
Plant Growth Regulator (PGR) names must meet pre-defined naming requirements and be understood and recognised globally.
Overall the requirements for naming PGRs include:
- Use of internationally accepted chemical naming (International Union of Pure and Applied Chemistry - IUPAC) or common names.
- Do not use identical or potentially confusing trade names.
- Clearly show the active ingredient on the label of the product.
- Include standard abbreviation(s) where appropriate (e.g., GA3, ABA).
- Be consistent throughout packaging, documents and research studies.
By following these guidelines, manufacturers and researchers can facilitate proper identification and utilisation of plant growth regulators.
Linking PGR Names with Crop and Function
PGR names that accurately represent the crop and/or the function of the PGR are more effective than those that do not represent these components. Giving a clear functional description aids the farmer in selecting the appropriate PGR fertilizer without having to rely on technical terminology to select the correct product.
Ways to improve functional clarity include:
- Indicate the growth stage (i.e., Root Booster, Flower Enhancer)
- Indicate when possible the target crop category
- Give concise descriptions on product labels
- Align the trade names to the regulatory hormone role.
Ensuring Long-Term Usability of PGR Names
To be utilized as sustainable agriculture, it is critical that the use of PGR nomenclature keeps its integrity for the purpose of tracking, regulatory compliance and building confidence within the marketplace.
The following guidelines will assist in the development of sustainable-use PGR names.
- Keep a centralized electronic data file of active ingredients.
- Minimize the number of times identical formulations are renamed (e.g., products with different names but same formulation).
- Use internationally-accepted nomenclature practices according to the respective national regulatory submissions.
- Provide education/training for both distributors and producers on how to correctly identify the appropriate product.
The credibility of the nomenclature provides assurance of safe use of PGRs, maintaining accurate records for PGR fertilizer, and facilitating effective communications among all links in the supply chain.
