The Southern Ag Atrazine Weed Killer for St Augustine Grass product label does not recommend tank mixing with other chemicals but would Turf Mark Blue have a negative effect if tank mixed?
Southern Ag Atrazine Weed Killer for St Augustine Grass can be tank mixed with Turf-Mark Blue Indicator Dye as it is not another herbicide and only a dye to help see where you’ve sprayed during the application.
