The combination of a new, effective fungicide treatment and smart phone technology offer cotton producers in affected areas a new tool to determine if they need to treat acreage for cotton root rot.

A “Cotton Root Rot Return to Treatment Calculator,” offers producers a decision aid for iPhone/iPad and android device users. The app was developed by Texas AgriLife Extension with an assist from San Angelo State University.

“Cotton root rot is a fungal disease that for decades has essentially eliminated thousands of acres of cotton across wide swaths of Texas,” said Bill Thompson, AgriLife Extension economist at San Angelo, one of the apps’ authors.

Producers who utilize Apple mobile devices, iPhones and iPads, can download the app from Apple’s iTunes Store, while android device users can download the app from the Google Play Store . A spreadsheet version of the decision aid can be found at .

All three versions of this producer decision aid are free to download and use.
