Cotton Root Rot Return to Treatment Calculator
• Texas A&M AgriLife Extension has developed this decision aid to calculate Cotton Root Rot Return to Treatment ($/Ac.) using the fungicide TopGuard®. Output is in the form of a sensitivity table, identifying economic thresholds for expected yields and percent of field affected by Cotton Root Rot.
• Topguard® has proven to be an effective control for Cotton Root Rot, but treatment costs can exceed $40/Ac.
The App
