Blue Gem Dye Spray Indicator 1L is a premium food-grade blue dye designed to enhance the precision of herbicide and pesticide applications. When mixed into your spray tank, it visibly marks treated areas with its distinctive blue hue, ensuring accurate coverage and reducing the risk of missed spots or overdosing. Blue Gem’s dye fades over several days (depending on the surface) under sunlight or washes away with rain, providing temporary identification without leaving a lasting impact. Compatible with various spraying equipment, including knapsack and boom sprayers, Blue Gem is an essential tool for anyone looking to improve the accuracy of their spraying operations.
