General objective:

A pioneering and multidisciplinary approach in the search for ecological solutions for the treatment of vine crops through microalgae extracts that can serve as biostimulants and substitutes for chemically synthesized phytosanitary products. In this way, they not only respond to a need in the vineyard for more sustainable and ecological solutions. They also value the polysaccharides of algae as biostimulants in agriculture.

Specific objectives:

  • Development and chemical characterization of algae extracts: Ulva ohnoiand Ruguloptertix okamurae
  • To characterize the biostimulant activity of the extracts against grapevine downy mildew and powdery mildew under controlled conditions, through plant physiology-based studies, molecular analysis, disease control assessment, and microbial ecology approaches.
  • To extrapolate the data to field conditions, in particular addressing the impact of the extract on vine development and on the chemistry and microbiology of grape composition.
  • To determine the potential impact on wine quality from a microbial and oenological perspective.
