Full Description

Blue-gem ® is a food grade blue dye that is mixed in the spray tank with herbicides and pesticides to help improve accuracy. An integral part of spraying, Blue-gem will identify the sprayed area by temporarily dying the area. The treated area stays blue for a few days after application (how long it remains will depend on the surface) and then fades with sunlight or washes away with rain.

Using a spray indicator, such as Blue-gem, will in turn save you money and time as you are not missing any areas or overdosing any areas by spraying more than once. It can be used in a knapsack or boom sprayer and is compatiable with herbicides, fungicides, insecticides, moss killers and liquid fertilisers.

To use; half fill the spray tank with clean water, agitate the water and add the required amount of blue-gem. Then add the pesticide or other treatment(s) and fthen fill the tank with water to the desired level and commence spraying.

Our Recommendation

  • Always read the product label before use.
  • Avoid getting the product on areas you do not want temporarily dyed.
  • Mix in with herbicides so you can clearly see the area you have sprayed.
  • Wear Gloves to avoid stained skin.
