After the Hi-Yield Atrazine Weed Killer is applied, what action is required after that?

Little knowledge of lawn care here! Do I just wait for the weeds to die? When can I apply an ez seed? Trying to get my centipede grass free of crabgrass (there’s lots of it!) and want to make sure I’m doing the right thing!

Answer:

There is no action required after an application of Hi-Yield Atrazine Weed Killer. You should allow 10-14 days for plants to show signs of dying. According to the product label: Rain or water within 2 or 3 days of application may decrease the effectiveness on emerged weeds. However, for the control of weeds from seeds, rainfall or watering is necessary within 7 to 10 days after treatme
