1) I confirm that I have no reservations against Ferramol (or generics), an iron phosphate product.
In what is "organically authorized" by virtue of dogma (it's natural), I distinguish what is clearly or predominantly harmful (natural or not, I don't care), and what is not. little or no ...
a) Pests:
- copper sulphate (Cu is toxic for many organisms, has negative effects on worms, and remains in the soil for a long time, like other metals - Nickel, Cadmium, etc.)
- certain broad spectrum insecticides (in particular pyrethrums or derivatives); action against amphibians ...
They are excluded.
b) Little or little harmful:
- Ferramol (iron phosphate); both iron and phosphate are elements present in quantity in the soil, which plants use as nutrients ...
- Micronized sulfur: S has an antifungal action, especially against powdery mildew; it oxidizes very quickly, almost instantly (remember matches in S) and then goes back into the air; it is also an element that plants need; as a rule, our soils lack S; some crops are demanding (in particular the former crucifers, now Brassicaceae).
- auxiliaries such as Bacillus thuringiensis (Bt - anti-caterpillars and larvae), certain nematodes (Ph and some others); preferably those from our soils or regions (because exogenous sometimes have very negative effects by occupying the niches of our organisms - see Chinese Ladybug) ...
The a) I do not use. The b) I can use (even if I have not yet opened a box of S that is 5 years old or a box of Bt; it's just lazy and time to react, the problem was either solved - tracks on my cabbages, no doubt thanks to the hornets and / or chickadees - or desperate - cucurbits in the fall, once it condenses every night.
Finally, I am sad to see that I use "dogma": it uses because I said it! This is the exact attitude I hate. That of sheep! Tell me: "Didier explained such and such a thing (see above), so I have decided whether or not to ... "That's the point of explaining. I just have to give orders then!
