How long before I see wilting or the weeds dying after using SpeedZone Lawn Weed Killer Concentrate?

My lawn is heavy with Henbit and Hairy Bittercress..


Per the manufacturer ,evidence of injury can be seen within hours of application, and plants will die in 7 to 14 days once treated with SpeedZone Lawn Weed Killer Concentrate .
