Why use Blu-Mark when spraying?
Pattern Marking: Blu-Mark is used to mark where you have sprayed and this is important for two reasons, first of all it will show any parts that have been missed whilst spraying to guarantee total coverage, and secondly because everywhere is marked it will avoid overlapping and doing the same area twice which leads to a waste of weed killer.
Reduction of drift: Blu-Mark will significantly reduce (but not eliminate) spray drift.
Advantages of using Blu-Mark dye.
- Avoid overlapping and re-spraying an area twice
- Easily see missed areas
- Naturally breaks down in sunlight or rainfall
- Greatly reduces spray drift
