PCT Reactor Red Dye 1L – Red Spray Marker Dye for Herbicides & Sprays

PCT Reactor Red Dye 1L: Red Spray Marker to See Exactly Where You Have Sprayed

PCT Reactor Red Dye is a liquid spray marker dye that you add to your herbicide, pesticide or spray mix to temporarily colour it red. Once it's in the tank, the spray shows up clearly on the ground and foliage as you go, so you can see exactly where you've already treated. That takes the guesswork out of spraying: you avoid missing patches, avoid doubling up and wasting chemical, and get more even, accurate coverage across the area. This 1L bottle of Red Dye has a built-in measure chamber that makes it easy to dose the right amount into the tank.

A spray marker is especially useful with clear herbicides like glyphosate, where the spray is otherwise invisible on the ground and it's easy to lose track of what you've covered. The red colour is a visual guide only while you work, and it fades over the following days rather than staining permanently.

Why Use a Red Marker Dye

• See your coverage as you spray, so you don't miss strips or spray the same area twice

• Save chemical and money by avoiding double application

• Get more even, professional results across paths, fencelines, beds and larger areas

• Handy when more than one person is spraying, or when returning to a job, to see what's already been done

How to Use It

Add the Red Dye to your spray tank along with the herbicide or spray mix, using the measure chamber on the bottle to dose it, then agitate so it mixes through. Spray as normal, and the treated areas will show up red so you can track your coverage. Use enough dye to see the colour clearly against the surface you're spraying, and follow the directions on the label for the amount to add. Rinse equipment after use as you normally would.
