For over 50 years, Smithers has conducted residue analysis studies to meet internationally-recognized testing guidelines. We test a wide variety of crop protection products in plants and livestock, and our responsive team manages studies from initiation to submission to ensure on-time delivery. Our analytical chemists have expertise in method development and method validation, and can design customized multi-residue testing programs for both active ingredients and metabolites.
With the acquisition of ResChem, Smithers has expanded its global pesticide residue offering and field cooperators network to conduct field trials in support of crop residue operator exposure studies.
Capabilities include:
Animal Residue Studies (also known as Livestock Feeding or Animal Transfer Studies) are an important component of pesticide registration. North America, Europe, Australia, and Japan require testing according to guidelines OECD 505 / OCSPP 860.1480.
Field Residue Studies
Smithers provides GLP-compliant residue chemistry studies for global registration and environmental monitoring needs. Our expert team has experience in analyzing all major plant matrices.

Crop Residue Processing and Analysis
Agriculture is one of the fastest-growing fields, so the study of crop residues has become an incredibly important process. A crop residue processing study focuses on the innovative techniques that are used to analyze left-over plant materials after harvest. The process goes further with the use of crop storage stability testing, which ensures that residues maintain their integrity over time, which is necessary for accurate analysis of residues.
Enhanced Extraction and Testing Methods
Extraction efficiency testing is used to maximize the effects of agricultural studies. It does this by ensuring the maximum amount of chemicals are recovered for precise analysis. Similar to extraction efficiency testing, import tolerance testing and independent laboratory validation (ILV) ensure the standards of these studies are upheld, ensuring they meet all necessary guidelines and can be recreated across different labs.
Advanced Studies in Residue Dynamics
It's imperative that you understand the accumulation and movements of residues. To shed light on how substances transfer through crops and their impact on later plantings, you'll need to have a deep understanding of residues in rotational crops and residue accumulation in rotational crops from soil uptake. Storage stability testing of residue samples, such as frozen storage stability, will keep samples unchanged during storage, which maintains testing integrity throughout the entire process.
Additional Methodologies and Technologies
You'll need great supporting technology and methodologies for any successful residue testing. Residue analytical support and radiovalidation are essential when it comes to enhancing the accuracy of residue analysis. Residue analytical methods (RAM) continue to grow and change, offering better techniques for detecting agricultural residues. We highly value agricultural safety and integrity, which is where an Operator Exposure (OPEX) Study comes in, monitoring potential risks from pesticides. With the precision of a pesticide residue analysis, it ensures the final product is safe for everyone. Thanks to rigorous residue cross validations, we can enhance the accuracy of our testing methods, further solidified through residue method validation. Altogether, these processes safeguard the agricultural workforce and the global food supply.
