How much area the Hi-Light Spray Indicator Blue covers depends on the rate you use for how much color you want on the area you are treating. You can use between 6 oz to 32 oz in 100 gallons of solution per the product label.

The SDS indicates that “this product does not contain any components classified for health hazards above the relevant cut off value,” so it does not pose any imminent risk to people or companion animals. You can contact BASF at +1 973 245-6000 or +1 800 526-1072 (toll free) if you wish to discuss the use of this product in areas with grazing animals for food or dairy production.
Hi-Light Spray Indicator Blue to the tank mix will not effect the application. Please refer to the product label for the proper amount for the area you will be treating.
The Hi-Light Spray Indicator Blue is not labeled specifically for use on hay or anything being used as a harvest for animals. While most temporary dyes of this nature are food grade colorants that should not harm anything, since it has not been tested for this use by the manufacturer, we cannot recommend it or advise of a pre harvest interval with its use with any other herbicide or products you may be applying it with.
Yes, Hi-Light Spray Indicator Blue will stain concrete, brick, stucco, rocks, etc. Apply with caution in these areas or cover any areas that you do not want sprayed. Any accidential overspray should be rinsed immediately with water to help prevent staining.
