How many days before you water if you want to treat both emerged and weeds from seeds with Hi-Yield Atrazine Weed Killer?

Should I look for a window of no rain for a week in order to kill both the emerged weeds and the seeds with one application?


Per the product label for Hi-Yield Atrazine Weed Killer: 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 treatment.
