Tru-Blue Spray Indicator Dye

Tru-Blue Spray Indicator Dye is a highly visible spray marker that helps you clearly see where you’ve already sprayed when applying herbicides, pesticides, fertilisers and other lawn treatments.

Adding a spray indicator to your tank makes it easier to achieve even coverage, helping reduce missed areas and unnecessary overlapping — particularly useful when treating larger lawns.

Why use Tru-Blue Spray Indicator Dye?

• Clearly shows areas already sprayed
• Helps reduce missed spots and overlapping
• Makes lawn spraying easier and more accurate
• Suitable for use with a range of lawn and turf spray applications
• Great for DIY lawn care and turf maintenance
