Raynox is a translucent film made from a proprietary blend of carnauba wax and other natural ingredients that help filter UV, visible, and infrared light and reduce the amount reaching the fruit surface. Every year, millions of dollars' worth of quality fruit is lost due to sunburn damage. Sunburn can be caused by high fruit surface temperature (FST) and/or exposure to solar radiation. Raynox lowers the “stress load” in the fruit by reducing the generation of free radicals, resulting in fewer sunburn symptoms. Raynox products reduce sunburn by an average of 50%, significantly increasing the packout of premium fruit.




Raynox was developed at Washington State University and has been extensively tested in collaboration with the Washington Tree Fruit Research Commission and other renowned research institutions worldwide. Independent testing conducted by the Washington Tree Fruit Research Commission demonstrated that even under extreme sunburn conditions, Raynox performs as well as or better than particle film products.

Raynox vs. Particle Film Protectants
Most sunburn protectants in the tree fruit market are “particle film” based. Particle film-based products provide good protection against solar radiation through physically blocking light exposure to the fruit surface. Particle films leave an unsightly residue on fruit while reducing photosynthesis of leaves and interfering with color development on apples. Furthermore, particle films cannot be used in combination with evaporative cooling, a method which dramatically reduces FST, and must be reapplied after a rain event. Raynox provides thorough sunburn protection by delivering a clear, water resistant (rain-fast) coating that does not interfere with photosynthesis or coloring and is compatible with evaporative cooling, resulting in improved fruit quality and increased grower returns and profits.

Multiple Benefits of Raynox

Beyond its notable sunburn protection properties, Raynox also offers growers a host of other important benefits:

  • Raynox does not leave a visible residue, allowing growers to color pick
  • Raynox does not cause irritation to nasal passages or skin of orchard workers
  • Raynox has no negative effects on beneficial insects
  • Raynox does not encourage mite flare-ups
  • Raynox does not wash off easily or require reapplication after an occurrence of rain
  • Raynox does not leave residues in dump tanks that call for special disposal


Raynox + EC for Optimal Protection
Use of Raynox will significantly increase the efficacy of Evaporative Cooling and provide growers with the best possible sunburn protection program. The combined use of EC and Raynox has shown to reduce sunburn by as much as 97%.
