Kaolin for Agriculture

Intense sunlight causes sunburn on fruit and heat stress in plants, reducing yield and quality.

Kaolin is sprayed onto crops to form a white, breathable "particle film". This layer reflects harmful UV and Infrared radiation, keeping the plant cooler and preventing fruit burn, while still allowing photosynthesis light (PAR) to pass through.

  • Prevents Fruit Sunburn (Apples, Pomegranates, etc.)
  • Reduces Heat Stress & Water Loss
  • Deters Pests (Physical Barrier)

Frequently Asked Questions

Will it block photosynthesis?

No. The white particle film reflects harmful UV and infrared heat but allows the visible light spectrum needed for photosynthesis to pass through, often improving efficiency by cooling the leaf.

Does it wash off?

It is designed to adhere during light rain but can be easily washed off in standard packing house washing lines using brushes and water.

Does it help with bugs?

Yes. The dusty/chalky surface creates a physical barrier that irritates insects and makes the fruit visually unrecognizable to certain pests.
