Foliar Mixing & Application Guidelines

Foliar sprays deliver nutrients efficiently and can provide rapid crop response when used in a sound fertility plan.

A Well-Designed Foliar Mix Includes

  • Clean water
  • Plant nutrients / fertilizers
  • Plant biostimulants (seaweed, hormones, enzymes)
  • Microbial biostimulants (fulvic & humic substances)
  • Microbial inoculants
  • Surfactant (add last)

Mixing Sequence (Tank Order)

  1. Fill tank with clean water
  2. Pesticides (pre-dilute; add before any bio products)
  3. Fertilizers / nutrients
  4. Plant biostimulants
  5. Microbial biostimulants
  6. Microbial inoculants (do not mix with pesticides)
  7. Surfactant (always last)
When in doubt, jar test and add one product at a time.

Timing of Application

  • Evening or early morning applications are preferred.

Avoid Spraying

  • When leaf surface > 78°F or ambient > 82°F
  • During rainfall
  • While leaves have heavy dew

pH & EC Targets

  • pH 5.2–6.4 for optimal nutrient absorption
  • EC < 3800 µS when applying multiple foliars in a season

Water Quality Matters

Ideal foliar water has < 70 ppm total hardness. If hardness is > 150 ppm, mixes can be up to 70% less effective due to carbonate/bicarbonate binding.

Preferred Sources

  • Rain water
  • Reverse Osmosis (RO) water — often allows 30–50% lower product rates vs. hard water
  • Tested clean water

Avoid / Use With Caution

  • Softened water (high Na/Cl; can skew sap tests)
  • Most filtered water (still may contain carbonates/bicarbonates)
  • City water (chlorine/chloramine antimicrobial)
