Plants protection

We found that mechanically lysed amoeba Willaertia magna C2c Maky exhibited strong fungicidal properties.

First on oomycetes (microorganisms close to fungi and responsible for mildews) then on phytopathogenic fungi such as rusts, powdery mildew, etc.

This has been demonstrated in laboratory tests and then, since 2019, has been verified in field trials.
