Dislodgeable foliar residue studies

Study

Environmental, Field Trials

In dislodgeable foliar residue studies, potential exposure of agricultural workers re-entering the field after application of a pesticide is estimated. Studies are run in more than one location, to represent the product’s range of crops, climates and pests. In the intended season of use and suitable weather (more than 24 hours before rain), the product is applied at maximum intended concentration to plants in the field. Samples are taken at increasing intervals until at least 35 days. Precise sample area is ensured using a 2.5 or 5 cm2 disc Birkestrand type or equivalent sampler and/or imaging processing software. Samples are shaken in an aqueous surfactant solution for a set time and the solution analyzed to report weight of dislodged pesticide per unit of leaf area.

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.
