Description
<EMI ID=1.1>
On connaît depuis longtemps des algues rouges de la famille des corallinacées, et désignées en langage
<EMI ID=2.1>
Bretagne, ou lithothamne, ou encore Lithothamnium cal- cerum dans les ouvrages scientifiques. Ces algues qui
se développent en mer à une certaine profondeur, généralement 10 à 20 mètres, sous le niveau de la mer, se caractérisent par une grande abondance calcaire qui incrus-
<EMI ID=3.1>
re de la mer les éléments minéraux qui s'y trouvent, de sorte qu'à l'analyse la composition de ces algues, qui serencontrent sous des formes ramifiées, calcifiées,

le reste étant de l'eau, des matières organiques, des traces d'iode et de brome et autre oligo-éléments, ainsi qu'une quantité d'environ 4% de silice colloïdale.
Il s'est révélé que ce Maerl convenablement broyé, à une finesse d'environ 50 microns, c'est-à-dire passant au tamis 300, avait un effet insecticide puissant sur les insectes à peau molle, c'est-à-dire sans chitine, tels que la plupart des chenilles, larves de doryphores, cochenilles, etc.
Des essais ont montré que par poudrage ou pulvérisation avec du Maerl, des arbres fruitiers, des pieds de pomme de terre, de la vigne, on obtenait à la fois une amélioration du développement de la plante et un effet insecticide certain.
On peut donner l'explication suivante de ce dernier phénomène :
Grâce à la silice colloïdale contenue dans le Maerl, celle-ci adhère aux corps mous et humides des insectes qui ne peuvent s'en défaire. la silice absorbe l'eau de la couche superficielle des insectes qui se dessèchent et meurent. De plus, la silice absorbée par la peau de l'animal se transforme dans les couches
<EMI ID=5.1>
quilibre alcalin; elle agit ainsi comme déséquilibreur biologique.
Ce traitement par produit naturel présente l'avantage d'innocuité totale contrairement à certains produits chimiques nécessitant pour leur emploi l'utilisation de masques ou de vêtements protecteurs.

Red algae of the corallinaceae family have long been known, and designated in language
<EMI ID = 2.1>
Bretagne, or lithothamne, or even Lithothamnium cal- cerum in scientific works. These algae which
develop at sea at a certain depth, generally 10 to 20 meters, below sea level, are characterized by a great abundance of limestone which

re from the sea the mineral elements found there, so that on analysis the composition of these algae, which are found in branched and calcified forms,

the remainder being water, organic matter, traces of iodine and bromine and other trace elements, as well as about 4% colloidal silica.
This suitably ground Maerl, to a fineness of about 50 microns, i.e. passing through a 300 sieve, was found to have a strong insecticidal effect on soft-skinned insects, i.e. say without chitin, such as most caterpillars, Colorado beetle larvae, scale insects, etc.
Tests have shown that by dusting or spraying with Maerl, fruit trees, potato plants, vines, both improved plant development and a definite insecticidal effect were obtained.
We can give the following explanation of this last phenomenon:
Thanks to the colloidal silica contained in Maerl, it adheres to the soft and wet bodies of insects which cannot get rid of it. silica absorbs water from the surface layer of insects which wither and die. In addition, the silica absorbed by the skin of the animal is transformed in the layers

alkaline balance; it thus acts as a biological imbalance.
This treatment by natural product has the advantage of total harmlessness unlike certain chemicals requiring the use of masks or protective clothing for their use.
