    does anyone have any experience using a colored surfactant? or even a colored spray? i am calibrating a new sprayer, using water first and thought it would be a good idea to use a color to see what i am doing.:dancing:

    You don't need color to calibrate, it is used to show coverage.
    Post this in the pest forum for more answers.

    The color you can add to your mix tank is called a "marker". Your chemical supplier will have what you need.

    turf tracking dye, actually, but when calibrating a new sprayer with water, I find asphalt, a stop watch, a measuring wheel, a bucket and measuring cup to be all you really need. run a 15 second spray away, measure the wet area and X4, you'll have your area per minute. run the pump into a bucket for 15 secs, measure it with the cup, times 4 and now you have flow per minute. That's all you need to figure rates from the label of whatever you plan to spray at that point. Forget dying things blue or green.

    I've tried it, a couple years ago. The dye is still all over everything in my toolbox! AVOID if possible!

    Leave your toolbox open in the sun. UV rays fade out the dye.

    Do what GreenUtah said. That is the only way to calibrate a sprayer.

    for the record, I hope the NC pest exam covers calibration!
