The Growing Need for Field Volatility Studies

Posted by WEI Info on December 19, 2016


Over the past few years, Waterborne experienced a surge in the number of field volatility studies being requested by the USEPA. Our team has significant experience in this area and our crop protection clients rely on this expertise to help them meet the Agency’s requirements.

Field volatility studies present unique logistical challenges. The required plot size for these trials are generally quite large and may be dependent on what type of vegetation is present. Other major considerations in the selection of a site are proximity to non-target plants, neighboring applications and wind obstructions. These requirements make site selection a critical part of the planning phase and we work closely with our extensive network of field cooperators to identify the best study location for our clients.

A good volatility study design is critical to ensure sufficient data is collected to quantify the flux rate from the plot. We have experience working with several different designs and can easily assist with quantifying the flux rate for a particular compound, comparing differences between formulations or performing a volatility study in conjunction with a dissipation or non-target plant effect study.

A significant amount of instrumentation is required to measure the precise air temperature and wind speed at various heights, as well as collect air samples at all required locations. To help fulfill this important need, Waterborne has a long standing and successful working relationship with Aaron Rotondaro, Paragon Research Services, to provide our clients with the highest quality data in these areas. Aaron has extensive experience with volatility studies and is well-respected in the industry.

In addition to the design and implementation of field volatility studies, we also perform the complex calculations associated with flux determination. We have experience with the Aerodynamic Flux Method, the Integrated Horizontal Flux Method and the Indirect Flux Method. We can efficiently summarize the results from each of these methods and present them in a meaningful way.
