Can I use Atrazine and Barricade a day apart on St. Augustine prior to rain/watering?


We recommend that you use them one week apart to avoid over-stressing your turf. You should apply the Barricade first as it needs to be watered in. Atrazine is a bit different. 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.
