Key Benefits from BRANDT iHammer Technology
BRANDT iHammer’s ‘glycoregulator technology’ is backed by strong basic research, including the established link between plant nutrition and glycoregulation. Specifically, this technology is based on the interaction of carbohydrates with the plant lectin cycle. Lectin proteins bind carbohydrate, which can limit its use for important primary metabolic processes such as photosynthesis. The technology works by increasing carbohydrate availability for utilization by the plant. BRANDT's Discovery & Innovation group has tested this technology on fine turfgrasses in the field and greenhouse with promising results, including enhanced root growth and improved performance under drought stress. Presumably, structural carbohydrate is being allocated to turfgrass root production – leading to enhanced water acquisition. But is the structural carbohydrate limited to root growth? What about shoot growth and development? The answers to these questions are of a practical importance because a turf manager wants to produce turfgrass density and vigor with out excessive shoot growth.
In a recent trial conducted in collaboration with Auburn University, we tested the BRANDT iHammer technology to determine its effect on turfgrass growth and development compared to a high rate of soluble nitrogen (N). Creeping bentgrass var. Penn A-4/G-2 mix was maintained in the greenhouse and treated with BRANDT iHammer's MegAleX® 3-0-0 (7.3 fl. oz./1000ft2) or urea-N (0.23 lbs N/1000ft2).

The first treatment was made on 10-Oct 2019 and continued every 14 days for 3 months. Quality rating, clipping yield (dry weight), photosynthetic activity, root weight and shoot density were measured and recorded. Urea significantly increased shoot growth as measured by clipping yield and MegAleX produced shoot growth similar to the untreated turf (data not shown).
No treatment difference in root weight were observed in this trial, however, MegAleX produced slightly higher root dry weight numerically. Most interesting, MegAleX treated turfgrass produced significantly higher shoot density than the other treatments (Figure 1.)
While the root growth differences were not significant in this trial, there were two (2) key findings from this work.
- MegAleX did not increase shoot growth compared to untreated, while the soluble nitrogen did.
- MegAleX increased shoot density.
This study provides further proof of concept for increasing the availability of structural carbohydrate by our glycoregulator technology. It also suggests a possible preferential pathway for tillering/root production in lieu of shoot growth. This has tremendous implications for improving turfgrass drought and traffic tolerance, and improved resistance to root feeding biotic pests – all without compromising playability that’s typically associated with unwanted shoot growth.
