Crop protection & agrochemical rotation studies

Study

Environmental, Field Trials

Crop rotation studies are extended field trials carried out when tier 1 and 2 studies, OECD TG 502 and 504, have shown residue accumulation in soil or significant residues in plants (in TG 504: 0.01mg/kg or above for plant-back intervals > 30 days). 

These studies provide information for setting maximum residue levels and label restrictions. Target primary and rotational crops are chosen from different crop groups, in combinations typical for the intended use of the product. 

Field trials are carried out at multiple locations to represent the main geographical distribution for the chosen crop combinations, usually four locations (eight, for major crops such as cereals). Application is at the maximum intended rate.

About our nonclinical animal research models: We provide the utmost care for our research animals and actively pursue advances in animal welfare. As well as ensuring the highest scientific, ethical and regulatory standards, selection of appropriate animal research models for development research is critical to developing safe and effective treatments, devices and products that protect and save lives. Just as we have ethical committee oversight for human trials, we have ethical committees overseeing all aspects of our global animal care and use programs. All of our core, nonclinical facilities are accredited by AAALAC. Learn more about our commitment to replacing, reusing and refining nonclinical research models.
