With Hi-Yield Atrazine Weed Killer you might be able to see results within 7-14 days, make sure that the product is labeled to kill the weed(s) you're trying to kill. Per the product label, "Rain or water within 2 -3 days of application may decrease the effectiveness on emerged weeds but for the control of weeds from seeds, rainfall or watering is necessary within 7-10 days after treatment".
