Backlighted Night Spraying

Add a Backlit Night Spray Demo or Flourescing Tracer Dye Demo,  or both, to your summer meeting- your growers will talk about it for years. Nothing puts the focus on better application like seeing every drop! Scroll down for a short demonstration video.


  1. Allows growers to make better decisions regarding setup and operation of their sprayers
  2. Shows effect of adjuvants and drift reducing agents on a spray plume
  3. Allows growers to see a qualitative difference between various sprayer technologies
How it works:
  1. Your growers or local dealers, or both, bring their (cleaned) sprayers to the demo site.
  2. Special lights are installed in the orchard or vineyard so that the spray can be seen by light diffracting through the droplets
  3. Each sprayer is demonstrated at twilight to show what it looks like in the day.
  4. If Fluorescing Dye Demonstation is also chosen, sprayers can apply the dye at this time in separate rows.
  5. After it has gotten dark, the lights are turned on and the demonstration is re-ran. Growers are able to see off-target spray and air movement through tree much more comprehensively.
  6. If Fluorescing Dye Demonstration also done, "black lights" will also be handed out at this time
