Blue gem® helps you see the areas you have sprayed. This avoids overdosing some areas and missing others. The treated area stays blue for a few days depending on the surface. It then fades with sunlight or washes away with rain.


Our Recommendation

- Mix in with herbicides so you can clearly see the area you have sprayed.

- This eliminates missed areas and overdosing

- Wear Gloves to avoid stained skin
