Dye

Marking dye is a spray adjuvant that is used in pesticides for the purpose of temporarily indicating where you have applied your pesticide or fertilizers.

Dyes are helpful when it comes to weed management, making the process more efficient by being a clear indicator of where herbicides, pesticides or other chemicals have been sprayed. This prevents over spraying from happening or the applicator forgetting where they have already sprayed.

Adding dyes to a pesticide product is very easy to do. Simply add a minuscule amount, following label directions for how much exactly, to a tank sprayer that contains a pesticide mixture and shake and begin spraying.

User Guide

Tools Needed

• Selected Herbicide Product
• Vision Marking Dye
• Handheld or Backpack Sprayer

PPE

• Chemical Resistant Gloves
• Dust / Mist Mask
• Safety Glasses

Step 1: Mix up the Insecticide Concentrate

Make sure that you always read and follow the label instructions for proper mix and usage rates.

Step 2: Add and Mix The Dye

To use spray marking dye, read the product label to determine how much of the product you will need. After that, you simply measure the amount of dye needed, then pour it into a sprayer. Shake your sprayer to agiatate and ensure it is thoroughly mixed.

For Vision Blue Dye, the rate is 32 fl. oz. per 100 gallons of spray solution or 0.32 per gallon for smaller handheld sprayer applications.

Step 3: Apply the Spray and Dye Mixture To The Target Area

With your PPE on, begin applying the dye herbicide mixture you created the target area needing to be treated. A flat fan spraying nozzle tip is recommended when applying. The dye will stay in the treated areas until it rains or until it degrades from the sun.

While these materials wash off of most surfaces with soap and water, care should be given to avoid spraying hard surfaces where unwanted staining may occur.
