Spray Indicator

Spray indicators are colored products added to products like herbicides, insecticides, and fertilizers, to help you see where you spray for proper application. The color can remain visible for a few hours up to a few days, and is usually blue or green. Spray dye indicators are an essential part of the spraying operation. Whether using a herbicide, fungicide, growth retardant, liquid fertilizer or iron products, it is essential that you apply the product both accurately and uniformly.
