By United States Department of Agriculture, Agricultural Research Service

This app is only available on the App Store for iOS devices.


Agriculture’s (USDA), Agricultural Research Service (ARS) who has worked close with the Dept. of
Defense’s Deployed Warfighter Protection Program (DWFP) to evaluate a number of sprayers used to
spray pest control products targeted insect vectors of human and animal diseases. Using facilities at the
U.S. Navy Entomology Center of Excellence, nearly 100 different sprayers have been tested for droplet
size under various operational setups (nozzles, pressured, flowrates, spray solutions, etc…). Over the
past several years, this data has been incorporated into an extensive database. This app provides users
with a quick, easily searchable interface that returns droplet size data for the specified operational setup.

The database is structured such that users are requested to select specific operational parameters which
- Company Name (of the spray system used)
- Spray System (model number)
- Solution Type (carrier solution used)
- Additive/Insecticide
- Sprayer Setting/Nozzle
- Pressure (psi)
- Flowrate (oz/min)
- Dilution

Using the above specified parameters, the app will provide droplet size results to the user. These
- DV0.1, DV0.5, and DV0.9
o Droplet size (in µm) such that 10, 50, or 90% of the spray volume, respectively, is
contained in spray droplet sizes of equal or less.

The results, along with the initial parameters, are time and date stamped and can be saved to the user’s
device under any name of their choice. The app allows for these results to be emailed to any address of
their choice. The saved results can be viewed or emailed at any time.
