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. Smithers delivers timely, cost-effective sample processing and analysis capabilities.

We work with field management groups and field operators for coordination and conduct of field trials in growing regions across North America and Europe. Our expertise is highlighted with sample processing/homogenization and analysis at our laboratories in the UK and USA. WIth the acquisition of ResChem, we have added capabilities for residue analysis in crops, soil, water, air, animal products, and matrices associated with operator exposure and ecotoxicology studies.

We test all modalities of crop protection products, 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 easily customized multi-residue testing programs for parent compound and metabolites.

Capabilities include
  • Field Dissipation (Soil or Aquatic)
  • Field trials in collaboration with field contractors
  • Decline of residue (DEC), magnitude of residue at harvest (MOR), groundwater and surface water studies
  • Dislodgeable Foliar Residue and Turf Transferable Residue studies
  • Magnitude of Residues
  • Aged samples originating from 14C-metabolism, field or dissipation (soil, sediment or water) studies

Ensuring Safety and Compliance

Residue studies are crucial to assessing the safety, efficacy, and environmental impact of agricultural chemicals. These important studies are crucial for regulatory compliance, ecological safety, and maximum residue limit testing.

Dislodgeable Foliar Residue Studies

A DFR study is a key part of field residue testing. It's an essential step to understanding the amount of residue that can be transferred from plant surfaces. This not only helps with safety protocols for workers but also for end-consumers.

Ecotoxicology Field and Residue Studies

Ecotoxicology field and residue studies are crucial to being able to properly assess the potential impact of agricultural chemicals on organisms that aren't the target of these chemicals. When paired with field ecotoxicology sample analysis, this study provides comprehensive data on the footprint left behind by pesticide use.

Soil Dissipation and Terrestrial Studies

A soil dissipation study and a terrestrial field dissipation study are pivotal to understanding the degradation or persistence of agricultural chemicals in soil. A soil dissipation and TFD study assists in evaluating the long-term impacts on the environment. This information assists in guiding sustainable agricultural practices.

MRL Testing and Field Trial Residue

When it comes to residue studies, MRL testing cannot be ignored. Determining the maximum residue limit will ensure crops are safe for human consumption. Field Trial residue analysis supports this by providing data on the magnitude of residue (MOR) in crops. This helps set the maximum residue limits.

TTR Studies

A terrestrial field dissipation study, along with soil dissipation studies, plays an important role in assessing the mobility of residues in turf and soil environments. These insights are crucial in terrestrial field dissipation accumulation studies, further ensuring the safety and sustainability of agricultural chemical use.
