After applying Celsius, how long does it take to kill sandbur?

Answer:

Weed growth ceases within hours after application of Celsius WG Herbicide. Symptoms progress from yellowing to necrosis resulting in plant death within 1-4 weeks after application. The speed of symptom development varies with temperature and will be faster at warmer temperatures. For best results to control mature weeds, apply when the daily average temperature is above 60° F. Make applications to actively growing weeds.
