Biodevas technology, producers testify :
EARL de Caubeyre (Lot-et-Garonne) has observed a much more homogeneous vineyard, regularity in the plots giving positive results and very good behavior despite excess water in winter and then water stress since late spring.
At Domaine de Chiroulet (Larroque-sur-l'Osse), results have been positive for grape varieties tested over the past 4 years. The cumulative effect of BOSCA applications gives better results, especially in situations of water stress. "What's more, using natural solutions to produce better is part of our philosophy".
Domaine de Fortunet (Gers, France) comments: "After two years of comparison on Sauvignon, Gros Manseng and Petit Manseng, I can only say that the results are positive, with better berry homogeneity. It's clear that our products work.

These testimonials regarding the BOSCA range from Biodevas Laboratoires the R&D work and tests carried out by independent organizations.
The Bosca range, which has been specially designed to accompany the vine throughout its cycle, regulates the plant's physiology and its natural defence mechanisms in order to :
- Limiting the impact of stress during the season
A trial carried out in Burgundy on a plot that had experienced a severe water deficit during the season, as well as wide temperature variations, showed a lower water stress (water potential measurement) for the treated vines. The trial also revealed better berry growth thanks to stress management during ripening (measurement of Delta C13 in grape must), while yield was maintained (see article January 2024).
- Improve the quantity and regularity of harvests
Trials carried out over several years have shown yield gains ranging from 5 to 20%, depending on the plot and grape variety.
A trial carried out in Burgundy this year revealed an 11% gain in the weight of 200 berries, while maintaining must quality.
- Encourage better stockpiling for consistent recovery the following year
Storage is the3rd pillar of vine nutrition. It conditions the nutritional potential of the floral organs, and therefore the following year's harvest load.
In spring 2025, monitoring of plots that had received the BOSCA program in 2024 showed a 39% increase in the number of bunches, with bunches 5% longer, in an organic plot of Muscadet. These differences translate into a 38% higher harvest weight.

These results and feedback from the field show a more productive, well-balanced vine, capable of coping with the stresses of the season while preparing for the next and expressing its full potential.
