Can Turf Mark Blue Dye Indicator be tank mixed with Southern Ag Atrazine Weed Killer for St Augustine Grass Atrazine?

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?

Answer:

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.
