Frequently Asked Questions
Why use an indicator dye?
Dye makes sprayed areas visible to prevent over- or under-application and highlights any missed spots.
What colours are available?
Commonly blue and green dyes are offered.
How much dye do I add?
Typical mixes are around 1oz per gallon of spray solution, or 2–3oz per 3gal knapsack load.
Is it safe with chemicals?
Yes – dyes are generally non-toxic, water-soluble, and compatible with most herbicides, pesticides, and fertilisers.
Will it stain surfaces or skin?
It temporarily colours surfaces and skin but usually washes off in 24–48 hours – avoid use on delicate light-coloured areas.
Do I need a specific applicator?
No – dye can be added to any tank mix and sprayed through your usual sprayer.
