Southern Ag Blue Colorant

Southern Ag Blue Colorant, manufactured by Southern Ag, is a simple yet powerful spray pattern indicator that helps applicators see exactly where pesticides and fertilizers are sprayed, improving accuracy, reducing waste, and delivering more consistent results across turf and ornamental areas.

Once mixed into a spray tank, it temporarily colors the spray pattern bright blue, allowing applicators to visually track where material has been applied. Unlike permanent dyes, Southern Ag Blue Colorant is temporary, fades naturally with sunlight and rain, remains inert with most pesticides and fertilizers, and won’t stain skin, clothing, or equipment.

Southern Ag Blue Colorant is a simple, reliable, and highly effective spray pattern indicator that takes the guesswork out of liquid pesticide and fertilizer applications on ornamental turf grass (non-grazed), non-crop land, and ornamental plants. Whether applicators are treating weeds, pests, diseases, or fertilizing ornamental turf and landscapes, this temporary spray pattern indicator ensures nothing is missed and nothing is wasted.

Tools Needed

A handheld sprayer, power spray equipment, or greenhouse fertilizer injector will be needed.

How to Use

• Step 1: Always read the label of the selected pesticide or fertilizer first to ensure compatibility. For handheld sprayers, use 1 tablespoon of Southern Ag Blue Colorant per gallon of water or 1 to 2 oz. of product per 4 gallons of water. Refer to the product label for specific application rates and restrictions. 
• Step 2: Fill your spray tank with water or fertilizer solution and add the recommended amount of Southern Ag Blue Colorant. Mix thoroughly for even distribution.
• Step 3: Spray evenly over the treatment area. The temporary blue color helps track coverage and will naturally fade with sunlight and rain, leaving no permanent stains.
