Julietta is a bio-fungicide that acts preventively. The active ingredient (Saccharmoyces cerevisiae strain LAS02) acts by spatial and nutritive competition against plant pathogens.


This yeast strain has been selected for its survival and quick development capabilities that allow it to colonize the medium before Botrytis and Monilinia. Its natural origin makes it an environmentaly friendly solution compatible with a modern and respectful agriculture for the environment, consumers and farmers. Julietta can be used in conventional, organic and zero residue agriculture.

Mode of action

Julietta acts preventively by space and nutritive competition.

The speed of development of Saccharomyces cerevisiae strain LAS02 prevents disease infections by protecting potential entrances on sensitive parts (fruits, wounds, flowers…). Julietta is able to develop into ranges of temperature and pH wider than Botrytis and Monilinia.
