Want to select the right spray nozzle for the job?

There's now an app for that, courtesy of TeeJet Technologies of Wheaton, Ill., according to a news release.

SpraySelect, as the app is named, can be downloaded free of charge for both Droid smartphones and iPhones.

Users enter the speed of the rig, tip spacing and target rate. They then select the droplet size category, and the app returns a list of recommended tips.

Users also can enter specific gravit if they're applying liquid fertilizers.

The app supports both U.S. and metric unit, as well as six languages: English, Spanish, French, Portuguese, German and Russian.
