Now you should all know by now that we at IMD HQ consider ourselves to be at the forefront in using smartphone technology and apps… we even have our own in case you were wondering (PPLAPP). But when I read that U.S. Department of Agriculture (USDA) scientists have released two mobile apps, to make things easier for anyone who needs to adjust insecticide spray equipment, I had to read on.
The apps incorporate the latest science of spray technology, including “spray nozzle atomization” models developed by ARS at College Station and they can be used with a smartphone from a field or even the cabin of a small aircraft. Developed by Agricultural Research Service (ARS) scientists Bradley Fritz and Wesley “Clint” Hoffmann at the agency’s Areawide Pest Management Research Unit in Texas, the apps are designed to ensure that aerial and ground-based crews can hit targets and minimize pesticide drift by keying in specifics on the type of equipment and pesticide they are using.
ARS is USDA‘s principal intramural scientific research agency, and the research supports the USDA goal of promoting agricultural sustainability. With dozens of manufacturers producing dozens of different types of spray technology—each with its own nozzle type, flow rate, and pressure setting range—the equipment setup can get pretty complicated. Aerial sprayers also must factor in wind speed, air temperature, flight speed and humidity.
One app is designed for ground-based spraying for mosquitoes and other threats to public health. It
covers 60 different sprayers made by 19 manufacturers. The user selects the appropriate sprayer and is guided through the process of selecting specific operational settings, such as the nozzle type, flow rate and spray pressure setting.
The other app, for aerial spraying, walks users through the process of adjusting nozzles and settings so pesticides are delivered at optimal droplet sizes. Droplet size is critical in aerial operations to ensure “on-target deposition” and minimize pesticide drift.
The apps are available online through the Apple iTunes App Store and the Google Play Android Marketplace by searching for “Aerial Sprays” for the aerial application app and “Vector Sprays” for the ground-based sprayer app.
