Enhancing Carbohydrate Transport for Tomato Yield with Damu
Tomato growers are constantly balancing the needs for size, yield, and soluble solids to meet market demands. Boron plays a crucial role in achieving this balance — but the type of boron and how it’s delivered can make a significant difference.
That’s where Damu, Levity Crop Science’s advanced boron product, is redefining tomato nutrition.
The Role of Boron in Tomato Crops
Boron is critical in:
- Cell wall development – influencing firmness and shape
- Sugar transport and fruit filling – supporting soluble solids and size
- Flower and fruit set – aiding reproductive development
- Nutrient movement and hormone regulation
However, standard boron products are often inefficient, especially during times of peak demand or rapid growth. This is where Damu offers a distinct advantage.
What Makes Damu Different?
Damu is not just boron — it’s boron enhanced with Catalyst technology, a proprietary stimulant system that improves both uptake and mobility. Catalyst facilitates the formation of boron-sugar complexes that travel efficiently through the phloem, enabling boron to reach developing fruits and flowers rather than accumulating in the leaves. This ensures more effective support for fruit set, filling, and maturation, particularly under conditions of high demand. that improves uptake and transport inside the plant.
Key benefits:
- Rapid foliar uptake for immediate use
- Improved phloem mobility, directing boron to actively growing tissues
- Enhanced carbohydrate transport, boosting sugar movement and fruit development
- Supports better fruit set, size, and soluble solids
Unlike conventional boron formulations that tend to accumulate in leaves, Damu’s unique formulation ensures rapid absorption and phloem mobility, allowing boron and associated carbohydrates to be efficiently translocated to developing fruit. This reduces leaf-level accumulation and the associated risk of toxicity. By enabling lower-dose application without compromising efficacy, Damu provides a safer, more targeted solution for enhancing fruit development. Damu is engineered for fast assimilation and efficient transport within the plant. It forms mobile complexes that move boron and carbohydrates from source leaves to developing sinks such as fruit clusters.
This means boron doesn’t just sit in the leaf — it helps where it’s needed most: in the developing fruit. Thanks to this mobility and efficiency, Damu can be used at low doses without the risk of leaf toxicity, making it safer and more effective for sensitive crops like tomato.
Glasshouse Trial Results – UK (Micro Tomato)
An additional glasshouse trial conducted at Myerscough University College tested Damu on micro tomato plants under controlled but hot summer conditions.
Significant Outcomes for Damu:
- ↑ Number of flowers (vs. untreated, p < 0.1)
- ↑ Number of fruits (vs. untreated, p < 0.1)
- ↑ Number of ripe fruits early in the season
- ↑ Fruit weight harvested during first 7 weeks
- ↓ Time to harvest (fruit matured faster than control)
- ↑ Cumulative fruit harvested (area under the curve) over full harvest window

Trial Results from China: Fruit Size Expansion
In a field trial conducted on tomato crops in China:
- Plants treated with Damu and conventional boron started with similar fruit sizes.
- After treatment, Damu-treated fruits grew significantly faster and reached larger diameters.
