Cut stump treatment should be applied within how many minutes after cutting?

• A. Within 30 minutes
• B. Within 2 hours
• C. Within 24 hours
• D. Within 3 days

Answer: (A)

Timing is crucial for cut-stump treatment because the herbicide must enter the exposed cambial tissue while the stump is still fresh and permeable. When the cut surface is newly exposed, sap flow and active tissue uptake allow the chemical to move into the stump and inhibit or prevent resprouting. As time passes, the surface dries, the stump begins to seal, and permeability drops, making absorption much less effective. That’s why applying within about 30 minutes after cutting is the best practice—the window narrows quickly and waits of 2 hours, 24 hours, or several days greatly reduce efficacy and increase the chance of sprouting. In the field, treat as soon as possible after cutting and keep to label directions for best results.
