Crop residue data you can build a dossier around
Understanding what residues a plant protection product leaves in crops and how those residues behave is essential for assessing consumer dietary exposure. We deliver GLP-compliant primary crop metabolism, rotational crop metabolism and residue studies from dedicated, controlled facilities, growing crops from seed to maturity.
Why plant metabolism matters
Consumers can be exposed to pesticide residues through treated crops, crops grown in previously treated soil, and animal products from livestock fed on treated feed. Determining the nature of residues at each stage is a regulatory requirement — and getting it right requires both scientific expertise and the right facilities. We've grown over two million plants in the last 20 years in support of this work, across a broad range of global crop types.
Three study types under one roof
Primary crop metabolism (OECD 501), metabolism in rotational crops (OECD 502) and residues in rotational crops (OECD 504) — all conducted in our own facilities.
Broad crop range
We work with cotton, lettuce, maize, potatoes, rice, soya, sunflower, tomato, turnip, wheat and more — grown from seed to maturity under controlled or field conditions.
Dedicated environmentally controlled facilities
54 environmentally controlled glasshouses, seven plant health quarantine growth rooms and five quarantine growth cabinets — capable of simulating most global climates.
Expert metabolite identification
Our Thomson Suite houses LC-Orbitrap, LC-ToF, LC-Qtof and NMR technology — giving you precise structural identification of known and unknown metabolites.
Radiosynthesis support available
We can support the synthesis of radiolabelled test items alongside the study programme, keeping your project on a single timeline with fewer handoffs.
QA team with 50 years of GLP experience
A dedicated Quality Assurance team with over half a century of GLP inspection and compliance experience underpins every study we deliver.
The facilities and expertise to take your compound from soil to safety assessment.
1.
Grow to maturity
Our glasshouse and CE room network — managed by a dedicated horticultural team — can accommodate and simulate most global growing conditions, from temperate cereals to tropical species.
2.
Identify the unknowns
Elucidating novel metabolite structures is technically demanding. Our experienced metabolic chemists and advanced MS instrumentation are equipped to handle the most complex characterisation challenges.
3.
Support to submission
We stay with you beyond the study report — supporting dossier development, expert regulatory advice and response to post-submission questions.
Over two million plants grown in support of science
The breadth of our plant growth infrastructure — from quarantine containment facilities to open field plots — means we can replicate the conditions your crop actually grows in, not a convenient approximation of them.
