Beat the Heat



You don't have to paint it white, just paint it right with DIFFUSION®!


A premium liquid calcium carbonate product, DIFFUSION helps manage light and reduce heat stress, resulting in more efficient water usage for the plant. The calcium carbonate crystals in DIFFUSION reflect light while their porous nature does not interfere with photosynthesis. Use DIFFUSION prior to any significant heat event of 92º or greater for better quality and higher yields.


  • Formulated to minimize sunburn and heat stress.
  • Flowable micronized dispersion of calcium carbonate.
  • Can be applied to all crops that are not calcium sensitive.
  • Can be applied both by air and ground, through most conventional spray equipment.
  • After application the plant surface will have a light white colored haze.
  • Store at temperatures above 34°F.


Light rays are absorbed into the plant. Too much sunlight results in energy converting to heat instead of photosynthetic activity.


Some products coat the entire plant resulting in too much reflection of sunlight and a reduction in photosynthesis.


DIFFUSION® disperses the sunlight, allowing the energy in the plant to remain in photosynthetic activity even at higher temperatures, resulting in better quality and higher yields.

Use with:

DIFFUSION may be used on many crops that are affected by heat stress, including but not limited to almonds, apples, apricots, avocados, cherries, citrus, figs, grapes, melons, nectarines, nursery stock, olives, onions, peaches, peanuts, pears, plums, potatoes, prunes, strawberries, sweet corn, tomatoes, walnuts, and watermelons.


DIFFUSION may be applied through most conventional spray equipment at recommended use rates.
