Last summer, mildew devastated many of our crops, whether in Belgium or in the north of France. It seemed interesting to us to seek to understand this enemy in a Cartesian way and thus cut short beliefs and misinformation on the subject.
We went to meet Professor Sébastien Massart who is a plant pathologist at the University of Liège - Gembloux Agro Bio-Tech. It explains to us from a scientific point of view the history of Mildew, its functioning, the research on its subject and the means of combating and preventing this scourge.
