When using glyphosate for non-selective weed control during establishment, a follow-up should be performed.

• A. True
• B. False
• C. Not Sure
• D. Not Applicable

Answer: (A)

The idea being tested is that follow-up weed control is necessary after using a non-selective herbicide during establishment. Glyphosate is used to clear the seedbed, but it doesn’t provide lasting residual control. Weeds can regrow from existing roots or germinate after the initial spray, so a subsequent check and treatment helps keep the site weed-free as the turf begins to establish. This follow-up could be another roundup application or another weed-control method, timed after you’ve waited for the initial spray to take effect and before or during early turf establishment. Without that follow-up, weeds may compete with the young turf and hinder uniform establishment.
