Field Trials

Field studies are essential in establishing the safety of crop protection products in the environment to ensure they are safe for consumers, farm labor and the general public.

Over 20 years’ experience running GLP field studies across the entire globe

A multidisciplinary team of experts, including dedicated field operators, with vast levels of knowledge and practical expertise

Flexible and innovative – able to develop and run tailored studies designed to meet your needs

Field trials mimic the real-life agricultural situation in which crop protection products are used. That means following GLP and GAP and ensuring realistic application and usage of the crop protection product. It also means being on the ground to document what is happening – both the expected and the unexpected. 

Field studies can be complex to set-up, unpredictable and often need interpretation across zones.

There are many challenges related to running field trials. You need to establish the most appropriate regions and crops for your study in line with regulatory requirements. You need to ensure studies are conducted in line with GLP and GAP and understand how results, especially for MRL, may be interpreted internationally. Timely sampling combined with robust and reliable analytics is essential. 

Your partner in the office and in the field

Whether you need a single trial or a pan-region trial program, we can help. Our expert agronomists and analytical chemists design and execute trials collaborating with our in-house residue chemists, ecotoxicologists, environmental fate and regulatory consultants to ensure successful delivery of study outcomes. As our partner, you will receive proactive communication from experienced Study Directors, timely specimen transfer, robust analysis with the benefit of in-life data review and interpretation by our analytical experts. Your reports will be high quality and delivered on time.

With in-field operators, we are on the ground to monitor study success and keep your trials on schedule. This includes calibration of farm equipment and ensuring GLP training or registration for all farmers (where applicable) and co-operators who are fully GLP registered within their countries. As expert project managers, the field trials team co-ordinate multidisciplined activities, providing technical expertise and meeting with regulatory authorities (if required).

Whether you need a standard or tailored study designed to meet your specific requirements, our team of experts can help based on their track record of running many types of field studies, including:

  • Raw agricultural commodities (RAC) and processing
  • Soil dissipation and accumulation
  • Crop rotation
  • Dislodgeable foliar residue
  • Operator exposure studies (OPEX)
  • Worker re-entry studies
  • By-stander studies
  • Fumigation of soil, facilities and containers
  • Post-harvest studies on any crop and workers
  • Others  - import tolerance, sprayability or volatilization studies

Track record of running all manner of field studies

 Labcorp has experience and capability in running many types of field studies for a range of crops including:

  • Raw agricultural commodities (RAC) and processing
  • Soil dissipation and accumulation
  • Crop rotation
  • Dislodgeable foliar residue
  • Operator exposure studies (OPEX)
  • Worker re-entry studies
  • By-stander studies
  • Fumigation of soil, facilities and containers
  • Post-harvest studies on any crop and workers
  • Others  like import tolerance, sprayability or volatilization studies

Raw agricultural commodities (RAC) and processing

On-the-ground insight optimizes the selection of suitable field co-operators across the world. Outdoor, indoor and glasshouse facilities mean a range of crops can be studied for a long period of time throughout the year. In Europe, our teams control freezer truck transportation to ensure the viability of specimens and expedite delivery to analytical laboratories.

 A range of processing facilities allow us to flex capacity based on specification needs and urgency. Our processing experience covers all crops (tomato, orange, etc.), any type of processed commodity regardless of its complexity (from juice or jam, to wine or oil) and any industrial or home processing procedures.

Soil dissipation and accumulation

Labcorp has extensive experience in soil dissipation and accumulation studies on many different soil types (including paddies) in Northern and Southern Europe. All study designs comply with OECD and EPA guidelines and EFSA and NAFTA guidance documents. One metre depth sampling is standard although this can be divided into smaller sections. Care continues after application with sand covering, irrigation or incorporation as appropriate. Onsite weather stations are standard and if necessary, overhead irrigation is provided to replicate historical rainfall.

Dislodgeable foliar residue

Extensive preliminary work with analytical teams ensures the optimization of dislodging procedures and the stability of dislodge solutions. We have the facilities and capability to undertake dislodging studies at field sites across Europe with many different crop types using 2.5 or 5 cm2 disc Birkestrand type or equivalent sampler. By employing the latest imaging processing software reliably measurement of leaf area can be guaranteed.

Operator (OPEX), worker (re-entry) and by-stander studies

For field studies focused on residue analysis, Labcorp has a successful track record of conducting OPEX studies, including passive dosimetry, biomonitoring studies and air sampling.  Our experience with many different application techniques (tractor-mounted equipment or knapsack), formulation types (liquid, dust or fumigants), crops (outdoor and indoor), re-entry patterns within sprayed crops or processing facilities combined with in-field analytical services provide a complete wrap-round support for you and your substance. 

Fumigation of soil, facilities and containers

Fumigants are difficult to work with. Their unique chemical characteristics make the preliminary preparations a very important part of the study. Labcorp has worked with fumigants in different scenarios providing a wide range of expertise for your study.

Post-harvest studies on crop and workers

Our expertise does not end in the field. Most of our commodities need to be processed before arriving to our shops. Sampling and analyzing the post-harvest commodities or monitoring the workers in the post-harvest facilities are a large part of our capacities and experience.

Import tolerance studies

Maximum residue limits (MRLs) and import tolerances (ITs) are important trading standards that relate to pesticide residues in food. An MRL is the maximum concentration of a pesticide residue or contaminant recommended by national authorities and international organizations.  For imported products, MRLs set in the importing country or region must be met.

An “Import Tolerance” application is needed to set an MRL for imported products such that trade can be facilitated. Due to a variety of reasons, there is a general disharmony of MRLs across the food producing world and this can cause trade problems for those involved in the import / export of agricultural products containing pesticides residues.

Labcorp has extensive experience in overcoming the challenges of running studies within countries without specific GLP field capacities and approaching different GLP regulatory bodies to confer compliance. Our in-house study directors successfully coordinate the shipping of frozen and refrigerated specimens all across the world and back to our laboratories.

Why Labcorp?

For those in relentless pursuit of a sustainable future, we strive to be more than a partner.  We are your source for the product development services, insights and answers you need to make life better for our planet and its people.
