Summary
Extract D, a micro-algae discovered in Brittany, has revealed its ability to directly kill plant pathogens. Following this discovery, Lionel Navarro and the agronomist Laurent de Castro founded the start-up Immunrise to market this product. If they proved harmless to humans and the environment, microalgae could reduce France's dependence on pesticides and thus help meet the requirements of France's Ecophyto 2 programme.
