Description Blu-Mark is a spray marker dye designed to visually indicate where herbicides or other liquid treatments have been applied. This helps ensure complete coverage, prevents missed areas, and avoids overlapping applications – saving time, reducing waste, and improving overall efficiency. Key Benefits: Visual Coverage: Clearly shows treated areas to avoid missed spots Prevents Overlap: Helps prevent re-spraying the same area, reducing chemical waste Drift Reduction: Significantly reduces spray drift (note: does not eliminate it) Environmentally Friendly: Naturally breaks down with sunlight and rainfall Application Rates: Mounted Boom Sprayer: Mix 100–250 ml of Blu-Mark per 100 litres of spray solution Knapsack Sprayer: Mix 20 ml per 10 litres of spray solution Ideal for use in agricultural, horticultural, and amenity settings where precision and efficiency are essential.
