I might still get called the air of nothing communist cucumber but ... for my part, I would call this document an infomercial from an international company (of Japanese origin apparently) that invests in industrial biocontrol (biopesticides, soil disinfectants, ...) and promotes them, in particular through advertisements in specialized newspapers like this one (whose "independence" we can therefore doubt), apparently with the aim of to compete with the world leader in chemical slug control, on the world agricultural market, including in conventional agriculture. Suffice to say, initially, that this kind of company does not revolve at all in the world of "more than organic" and the protection of living soils by marketing, for example, a kind of Bordeaux mixture that they themselves call "the most concentrated copper on the market".Did67 wrote:Here, some answers to questions (but seen from the point of view of the manufacturers, even if it is taken up by an independent newspaper - Phytoma): https://www.certiseurope.fr/fileadmin/d ... hytoma.pdf
It is now common knowledge that large companies invest a (large) share of their capital in this kind of scientific and even pseudo-scientific promotion, given the place that techno-science has taken today.
Regarding the content of the document, and if we are to rely on the information offered, we learn that this pesticide (is it the same for the "little" Ferramol for individuals?) "Acts on a big number species of slugs gray and black", that, contrary to what has been said previously, it is"almost insoluble, not washed out by rain". The product is weakly toxic for humans, a little more toxic for birds, a little more for worms. I am not a specialist (is there a toxicologist in the room?). ..but some questions / remarks: there is no test on bacteria, is it normal? The tests on worms, if I am to believe the figures in your book, were operated on the equivalent of 3 times 1 m2 of natural meadow! Is this scientifically convincing at the extended level? Do the figures announced on aquatic organisms actually correspond to a "respect" of these organisms, including in hydromorphic soil like mine? does it contain cadmium, as is the case for fertilizers (and here the natural presence of Cd in the soil does not prevent it from being a source of soil contamination)? ... etc I stops me there because the complexity of living things does not fit well with these experiences.
Perhaps this product is practically harmless as this document seems to tell us. Surveys indicate that garden soils are highly polluted, especially in heavy metals. There is a staggering fall in animal populations. Also gardens with living soil may have a responsibility, in the future they could become refuge areas ... This may seem contradictory: I put a little of my old box of Ferramol 3 days ago. .but I wonder if the use of this pesticide is really necessary to the point of violating one of the fundamental principles of the lazy vegetable garden.
