Purpose of the tests

March 7 to 9, 2018, LABOSPORT is intervened to assess the influence of the TENDANCE'HERB formulation on the overall aesthetic appearance and the performance of the lawn of the Colomiers BENDICHOU stadium (31), France.

This commission has been defined and coordinated in cooperation with the National Rugby League, the SASP COLOMIERS RUGBY and the City Council of COLOMIERS.

Results and interpretations

Benefits on the overall aesthetic appearance

Before application, the aesthetic appearance of the vegetable layer is heterogeneous. The situation perfectly characterizes a good rugby field (land/sand) at the end of winter. The field is in less mechanical stress than the central area.

After 48h, post application, the overall aesthetic appearance of the area impacted has increased by 22% and the land has increased by 11%.

The colour and the television rendering is more qualitative and harmonious.

Benefits on the photosynthetic active biomass

Before application, the activity of the plant on the ground is greater than 50% compared to the impacted area studied. The activity, however, remains low but in line with the period. Therefore the stress level of grass is much lower.

The injection of natural pigments through foliar medium has helped to have an increase of 27% on the area impacted and 18% on the land in the activity potential in 44h. The immediate simulation effect is not characterized, a sign of a less traumatized vegetation cover.

The injection of natural pigments has a very positive effect on the photosynthetic active biomass. In this more favourable context, the biostimulant effect is also high.

Benefits on the colour and chlorophyll pigmentation

Before application, the chlorophyll pigmentation is heterogeneous. This situation is induced by the seasonality, the floristic variability, and the overall health and stress level of the grass.

After 44h, the study characterizes an average post drying increase of 12% on the area impacted and of 7% on the land.

The injection of natural pigments has an artificial effect ("maquillage" effect) but also a stimulating effect on the chlorophyll synthesis.

Conclusion

The study on the vegetation cover highlights a positive and quick effect of the application through foliar medium of the Tendance'Herb formulation composed of organic pigments from dyeing plants.

In the results analysis, the formulation provides benefits for the colourful effect on the sports field, and the product proves to be an immediate biostimulant for the grass. The effect is greater when the grass and plant matter is in higher degree of stress.

Test report

1) Pre-application measurements

Pre-application Overall Aesthetic Appearance

Measures performed by the optical sensor in 49 points throughout the field and 12 points on the stripped area :

- Of the vegetation index : the vegetation indices are calculated in order to measure in a scientific way the vitality and the photosynthetic activity of grass.

- Of the Grass Index : this indicator allows a suitable, eco-responsible and more effective guidance regarding the use of fertilizer and the maintenance of a regular aesthetic appearance required for the high end sporting events.

- Of the potential biochemical activity (PAB) : the greater the values, the greater the photosynthetic activity of the grass.


2) Calibration of the assembly tractor/sprayer

The sprayer used for spreading the product has been calibrated in order to verify the quality of distribution (uniformity) and determine the precise quantity of product (water+ commercial formulation) to prepare for the treatment of the entire grass field area (9652m2).

3) Identification and quantity of formulation used

Tendance'Herb is an organic pigment system designed for water diluted applications. This formulation is environment and eco-friendly, specifically designed for professional turf and lawn applications. The formula is exempt from toxicological and eco-toxicological classification and does not contain any hazardous or toxic ingredients.

The amount of colorant used for this study was 48 liters (28L light green and 20L dark green). The total quantity of product prepared and used is 280 liters.
