UNL App: PeRK (short for Pesticide Recordkeeping) Version: 2.0

Developer: University of Nebraska-Lincoln Extension Pesticide Safety Education Program (UNL PSEP)

Cost: Free

Intended Audience: Pesticide applicators, crop producers, agronomists, and pest management professionals

Purpose of App: To create electronic records of pesticide applications

Description: UNL Extension's Pesticide Safety Education Program presents the second version of "PeRK" — a free pesticide application recordkeeping mobile app. Applicators who spray RUPs (Restricted Use Pesticides) are required by Nebraska state law to keep records of those applications for three years. This app meets all Nebraska state law requirements for RUP pesticide recordkeeping and is a handy tool for keeping track of all pesticide use from year to year. PeRK uses a device's GPS coordinates to note location of application.

The app records the

• pesticide product applied and how much was applied,
• product application rate,
• target site and pest(s),
• date and time of application,
• temperature,
• wind speed, and
• disposal method.

The records are saved and stored within the app on the device. They can be exported via email as a .csv file, which can be opened in Microsoft Excel and other common software programs. Records are saved to each individual device and are not part of a cloud or Internet database.

New features in version 2.0 include

• an updated interface;
• the ability to take and save up to three photos per record;
• the option to use the app as a guest to try the app without creating a profile;
• links to the UNL PSEP's Facebook, Twitter (You can tweet to us right from the app!), and YouTube accounts; and
• an added link to Nebraska's DriftWatch map in the app's "additional resources" section.

Contact information for the UNL Extension Pesticide Safety Education Program and Nebraska Department of Agriculture Pesticide Program, emergency phone numbers, a link to the DriftWatch website, and links to helpful publications also are included in PeRK.

Fit for Nebraska: PeRK is specifically designed to meet the needs of pesticide applicators in Nebraska, but is also used by applicators outside of Nebraska. PeRK accommodates non-Nebraska users by providing a "notes" text field for writing additional notes about the application to meet their state requirements.
