Sun Boost
Sun Boost uses titanium dioxide to enhance photosynthesis, fruit size and leaf development. The TiO2 foliar coating helps optimise light use on the leaf surface, supporting stronger growth and larger fruit, particularly in protected and high-value crops.

Pre-harvest and re-entry intervals are restrictions carried on pesticide labels. These products are not pesticides, so neither applies. For comparison, four hours is the shortest re-entry interval a registered pesticide can carry.
Photosynthesis enhancer from Vegalab Crop Science, powered by Titanium dioxide (TiO₂). Sun Boost targets Photosynthesis, fruit size, leaf development.
Foliar titanium dioxide delivers a photosynthesis-boosting effect by reflecting and re-emitting light to leaf chloroplasts. Plants capture more usable light under low-sun conditions; antimicrobial side-effect protects against foliar pathogens.

How can a leaf coating improve photosynthesis?
Light is the raw material of photosynthesis, and how efficiently a leaf captures and uses it sets the ceiling on growth. Sun Boost applies a titanium dioxide (TiO2 8%) coating that helps optimise the way leaves interact with incoming light, supporting more efficient photosynthesis - particularly valuable where maximising light use directly affects yield.
How does Sun Boost work?
Applied as a foliar spray, the TiO2 forms a fine coating on the leaf that helps the plant make better use of available light for photosynthesis. The downstream effect is support for fruit size and leaf development, as more photosynthetic output is available to build canopy and fill fruit.

Even leaf coverage matters - the effect depends on the coating interacting uniformly with incoming light.
Always read and follow the applicable product label.
Apply as a foliar spray during active growth and fruit development, ensuring even leaf coverage - the effect depends on the coating interacting uniformly with incoming light. Repeat through the growth and fruit-fill period to maintain the benefit as new leaves expand.
Which crops benefit most?
Sun Boost has been tested on greenhouse crops, berries and vines - protected and high-value crops where squeezing more yield and size out of available light has a direct payback. Greenhouse production especially benefits, since light is often the limiting factor under cover.
What outcomes does it support?
By improving how efficiently leaves use light, Sun Boost supports stronger leaf development and larger fruit. In settings where light is a constraint - greenhouses, dense canopies or lower-light periods - that improved efficiency can translate into measurable gains in size and yield.
