Agrosciences Studies

Plant and Animal Metabolism Studies

The use of crop protection products in agriculture can result in residues remaining in the corresponding plant and animal foods. Using plant and animal metabolism studies, our laboratories investigate the uptake and metabolism of agrochemicals in farm animals and plants.State-of-the-art analytical methods and 14C labeling enable Tentamus Agrosciences laboratories to identify metabolites.

Regulation (EU) 396/2005 sets maximum residue levels of pesticides for plant and animal based products.

Environmental Fate & Degradation

Because they are anthropogenic substances, the fate of agrochemicals in the environment begins with their application to agricultural fields. The fate of substances in the environment is influenced by chemical, physical, biological, and hydrometeorological processes in soil, water, and air.

Incomplete degradation of pesticides can lead to the formation of toxic transformation products (TPs). Environmental Fate (eFate) studies provide an opportunity to investigate the impact of agrochemicals on the environment (plants, water, soil, etc.).

Tentamus Group’s specialized laboratories can perform eFate studies for you including hydrolysis, field dissipation, mobility, photodegradation as well as biodegradation of various matrices and additionally offer studies outside the guidelines.


Method Development and Validation

New methods need to be developed and validated especially for new or special products, research projects or regulatory requirements. The Tentamus Group laboratories can support you in precisely these areas, offering method development and validation for agricultural biotechnology, the chemical industry, and food and feed additives.

For regulatory method validations in accordance with GLP (Good Laboratory Practice), including independent laboratory validations (ILVs), work can be performed to meet applicable requirements.

Physical & Chemical Characterization

For registration and approval of chemical substances for agriculture, it is necessary to analyze and characterize these substances physically and chemically.

For this purpose, the agricultural science team of the Tentamus Group has a number of methods at its disposal, the results of which are in turn evaluated and interpreted by our experienced specialists. New methods can also be developed and validated, and studies conducted. Studies include risk studies for storage and transport of chemical products as well as stability studies.

Characterization and analysis of Residues (laboratory, field studies)

Before crop protection products are registered and approved for the market, they require thorough testing and evaluation by appropriate accredited laboratories and, ultimately, regulatory agencies. In order to ensure the safety of plant food and feed, no residues or only residues in specified maximum levels may be detected.

With the help of various residue and field studies, the laboratories of the Tentamus Group can advise you on the level of possible residues of your crop protection products in the food and feed and develop appropriate solutions together with you.

Humidome Studies

To determine the volatility of an active ingredient in a particular formulation, our laboratories can perform humidome studies in a controlled test environment (generally within 24-hours). These can be performed both qualitatively and quantitatively and offer tremendous cost and time savings compared to expensive flux studies. They are repeatable and can test multiple formulations in a short period of time very efficiently to identify the ideal formulation.

The U.S. EPA has required companies marketing dicamba formulations to use humidome setups to evaluate the effects of certain parameters on the secondary movement of dicamba.

In controlled experimental environments provided by humidomes, the effect of temperature, relative humidity, spray solution pH, and a variety of tank mix partners on dicamba volatilization can be studied. As weed resistance to Round-UP increases worldwide, agrochemical companies have begun to incorporate dicamba into their formulations to prevent further weed resistance development. As dicamba is volatile by nature, it has created new challenges for growers who must deal with potential damage to neighboring crops. Dicamba manufacturers have been forced to develop new formulations in which the volatility of dicamba is minimized.

In support of humidome studies, our Tentamus Agrosciences laboratories can also advise and provide analytical support for the development of new agricultural products or improvement of a marketed agricultural product.

GLP studies

To determine the fate of residues in crops, animal products, soil and water from crop protection products, we conduct studies according to Good Laboratory Practice (GLP) guidelines. Single and multi-methods can be developed and validated.

In addition, our agroscience laboratories can determine and evaluate the storage stability of residues in various types of materials and samples.


The importance of biological pesticides has grown significantly in recent years. These include microbials (fungi, bacteria, viruses, protozoa, algae), pheromones, semi-chemicals, plant extracts, and insects and nematodes.

Here, too, you can benefit from Tentamus Agrosciences Services. We provide regulatory and analytical support (5-batch analysis, residue studies, physical and chemical characterization). We are happy to help you identify suitable procedures for your biopesticides and also to prepare the necessary dossiers.

Crop protection products, such as pesticides, herbicides or fungicides are mainly used in agriculture. The aim is to protect both neighboring natural habitats (soils, plants, water bodies) and the treated fields themselves. To ensure that agricultural products work only as intended – that is, to promote the growth of healthy plants and keep pests and weeds at bay – the Tentamus agroscience laboratories offer the following services to farms:

  • Soil Dissipation & Crop Rotation Studies
  • Environmental Fate – Biodegradation of products
  • Risk studies for transport & storage
  • Stability studies
  • Residue studies & field trials

Food Production Companies

The use of crop protection products not only affects fields and the environment, but also has an impact on the food that emerges from agriculture. The Tentamus Group therefore places particular emphasis on taking a holistic view of food production and offers food manufacturers a valuable total package. In our laboratories, we not only examine the crop protection products as such, but also the food on its way from the field to the plate.

The Tentamus Agrosciences laboratories are equipped with state-of-the-art equipment for residue analysis and are thus able to quickly and efficiently provide results on residues remaining in food and advise you on appropriate measures in case of excessive exposure.

Approval of

Only approved crop protection products may be placed on the market and used. Both approval and use are governed by EU legislation. In order to use a particular active ingredient, it must also be approved by the European Commission.

The placing of crop protection products on the market is regulated by Regulation (EC) No. 1107/2009. The EU member states each evaluate and approve crop protection products at the national level.

In Germany, the Federal Office of Consumer Protection and Food Safety (BVL) handles the approval of a crop protection product. In the U.S., the approval of pesticides and crop protection products is regulated by the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Federal Food, Drug and Cosmetic Act (FFDCA).

Tentamus Group’s agroscience laboratories, through their experienced and qualified team, have the regulatory and scientific expertise to assist you with the marketing of your pesticide products. In addition to our consulting services, we offer the following services:
