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.

by Industry


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

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:
