lu-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.
