Plant Protection Products (PPP) used in agriculture are strictly controlled both to ensure product quality and to protect the environment and human health. The conduct of comprehensive testing before these products are placed on the market is not only legally required but also forms the basis for reliable agricultural practices.
In this process, physicochemical tests conducted under Good Laboratory Practice (GLP) enable a detailed assessment of the quality, stability, and efficacy properties of the products.
What is GLP and why is it important?
GLP (Good Laboratory Practice) is an international standard that ensures tests in laboratory environments are conducted in accordance with the principles of quality, accuracy, and traceability. In particular, for PPP tests (Plant Protection Products), compliance with GLP standards is of great importance for the authorization of the product in both the national and international markets.
What are physicochemical tests for plant protection products?
Physicochemical tests for plant protection products include a detailed analysis of the structural and chemical properties of the product. These tests verify the stability, ease of use, safety, and efficacy of the product.
Key physicochemical tests:
- CIPAC MT 3.3 – Density
- CIPAC MT 75 – pH determination
- CIPAC MT 53.3 – Wettability
- CIPAC MT 184 – Suspending ability of aqueous suspension concentrates
- CIPAC MT 36 – Emulsion stability
- CIPAC MT 185.1 – Wet sieving
- CIPAC MT 171.1 – Dustiness
- CIPAC MT 172.2 – Flowability
Advantages of physicochemical tests under GLP
- Compliance with legal regulations: It is ensured that all legal requirements are met in the context of authorization and market placement.
- Reliable results: Tests in accordance with GLP standards provide repeatable and verifiable results.
- International validity: GLP-compliant reports are officially recognized documents in the global market.
- Consumer and environmental safety: The potential impacts of the products on the environment and human health are assessed already during the testing phase.
For whom is this mandatory?
All companies that develop, import, or seek authorization for plant protection products are required to have GLP-compliant physicochemical tests performed. In particular, in European Union and OECD countries, the full conduct of these tests is legally required.
Foundation for safe agriculture
Demonstrating the reliability and efficacy of plant protection products is an indispensable step in modern agriculture. Physicochemical tests conducted in accordance with GLP standards help ensure that manufacturers meet legal requirements and can bring environmentally friendly, safe, and high-quality products to market.
