Color Boost
Last updated:
Color Boost is a fruit and flower color enhancer that improves coloration, maturation timing and sweetness. Phosphorus, potassium, magnesium and sulfur with pyroligneous liquor support pigment development and ripening for more uniform, market-ready color.
Fruit and flower color enhancer — Color development, Pre-harvest application.
Fruit and flower color enhancer from Vegalab Crop Science, powered by P, K, Mg, S + pyroligneous liquor, phytic acid. Color Boost targets Fruit and flower color, maturation timing, sweetness.
High-phosphorus and potassium with anthocyanin-supporting trace elements drives pigment biosynthesis in fruit skin. Color development accelerates and uniformity improves in the 14 days before harvest.

Why does color matter at harvest?
For apples, grapes, cherries and strawberries, color is one of the first things a buyer judges — uneven or pale color downgrades fruit regardless of its eating quality. Achieving full, uniform color on schedule is therefore a direct driver of grade and price, and it depends on the right nutrition and energy during ripening.
How does Color Boost improve color and ripening?
Color Boost (0-13-6) supplies phosphorus, potassium, magnesium and sulfur alongside pyroligneous liquor (wood vinegar) and phytic acid. These support pigment synthesis and the energy demands of ripening, helping fruit develop fuller, more uniform color, mature on schedule and accumulate sugar for better eating quality. Potassium and magnesium in particular underpin the sugar and pigment pathways.
When and how should it be applied?
Apply as a foliar spray during the color-development and ripening window. Timing it to the onset of coloration gives the most uniform result, and one to two applications through ripening is typical. Good coverage of the fruit zone helps ensure even color across the crop.
Which crops is it for?
Color Boost has been tested on apples, grapes, cherries and strawberries — crops where color and finish are central to grade and value. It is most useful in premium fresh-market production where appearance commands a price premium.
How does it support sweetness as well as color?
The same phosphorus and potassium that support pigment development also drive sugar accumulation, so Color Boost improves sweetness alongside color. Magnesium supports the photosynthesis that supplies those sugars, making the effect on eating quality and appearance complementary.

Frequently asked questions
What is the application rate for Color Boost?
1:1,000–1:500 · 1–2 mL/L (3.8–7.6 mL/gal) · 1.0–1.5 L/ha (13.8–20.8 fl oz/acre) Application: Foliar spray at flowering, 1–2 applications.
Is Color Boost suitable for natural or organic programs?
Color Boost is a naturally derived input (P, K, Mg, S + pyroligneous liquor, phytic acid) designed to fit low-residue and IPM programs.
What does Color Boost do?
Enhances fruit and flower color, maturation timing and sweetness.
What is the analysis?
P 13%, K 6% (NPK 0-13-6), with pyroligneous liquor and phytic acid.
When should I apply it?
During the color-development and ripening window.
Which crops is it for?
Apples, grapes, cherries and strawberries.
Does it affect sweetness too?
Yes — the phosphorus and potassium that drive color also support sugar accumulation.
