Description
<Desc/Clms Page number 1>
On sait que les différentes espèces'de limaces, surtout celles des types Limax et Agriolimax causent de très grands' dégâts dans les cultures, principalement dans les cul- tures de céréales, de plantes fourragères et dans les cultures potagères.
Pour combattre les limaces, on a surtout utilisé jusqu'à présent des .substances irritantes telles que la chaux vive, la kaïnite, le sulfate de fer et le sulfate de cuivre.
Ces produits possèdent le grave inconvénient d'être phytoto- xiques et d'être très vite délavés par les pluies.
Plus récemment, on a préconisé l'emploi de meta- acétaldehyde principalement en mélange avec du son. Ce pro- duit est dépose en petits tas à intervalles réguliers mais cette m thode est difficilement applicable en grande culture.
De blus, l'acétaldéhyde est tonique pour l'homme et pour les animaux à sang chaud, à trop forte concentration, il est phy- tetexique.
<Desc/Clms Page number 2>
Il a été découvert que l'ertho-nitrochlorbenzène, le '-ne ou leurs m@langes montrent une action extrêmement efficace contre les limaces. Ces composés pos- sèdent sur les produits anti-limaces connus jusqu'à présent l'avantage d'être pratiquement insolubles dans l'eau et d'être absolument exempts de phytotoxicité.
Si on incorpore,par exemple; le p-nitrochlorbenzène ou l'o-nitrochlorbenzène ou leurs mélanges à raison de 10% avec du talc, de la sciure de bois, de la bentonite, du son ou un mélange de ces composés, on obtient une poudre conve- nant particulièrement bien à la destruction des limaces.
On peut aussi incorporer les nitrochlorbenzènes à un produit solide tel que de la colle ou de la dextrine, avec ou sans addition de son ou de sciure de bois, et le solide obtenu est concassé et épandu sous forme de petits morceaux sur les cultures.
L'utilisation de ces poudres est beaucoup plus aisée que celle des produits à base d'acétaldéhyde car on peut opé- rer par épandage, ou poudrage,.
On peut aussi mettre les nitrochlorbenzènes en solu- tion dans un hydrocarbure qui est, par un moyen connu, émul- sionné dans l'eau. On opère alors par pulvérisation.
Dans un test de laboratoire, sur carré de gazon tenu constamment humide et sous cloche de Lange-Welt, on obtient par poudrage au moyen de talc contenant 10 % d'o-nitrochlor- benzène, à raison de 1 kg. par are, une mortalité de 100 en quelques heures pour une population de 50 limaces par m2.
Dans un essai en nature sous cage, à raison de 50 limaces par m2 et avec un m lage contenant 10 % de talc, 80 % de son et 10 % de p-nitrochlorbenzène, utilise à raison de 1 kg. par are, on obtient une mortalité (le 100% en quel- ques heures.
<Desc/Clms Page number 3>
Dans un essai identique en nature sous cage, on ob- tient le même résultat en utilisant du son contenant 10 % d'un mélange de 66 % de p-nitrochlorbenzène et 34 % d'o-nitrochlor- benzène.
<Desc / Clms Page number 1>
It is known that the different species of slugs, especially those of the Limax and Agriolimax types, cause very great damage in crops, mainly in cereals, fodder crops and in vegetable crops.
To combat slugs, the main use has hitherto been irritating substances such as quicklime, kainite, iron sulphate and copper sulphate.
These products have the serious drawback of being phytototoxic and of being very quickly washed out by rains.
More recently, the use of meta-acetaldehyde has been advocated mainly in admixture with bran. This product is placed in small piles at regular intervals, but this method is difficult to apply in large crops.
From blus, acetaldehyde is a tonic for humans and for warm-blooded animals, at too high a concentration, it is phy- tetexic.
<Desc / Clms Page number 2>
It has been found that ertho-nitrochlorbenzene, ne or their mixtures show extremely effective action against slugs. These compounds have, over the anti-slug products known heretofore, the advantage of being practically insoluble in water and of being absolutely free from phytotoxicity.
If we incorporate, for example; p-nitrochlorbenzene or o-nitrochlorbenzene or their mixtures in an amount of 10% with talc, sawdust, bentonite, bran or a mixture of these compounds, a powder which is particularly suitable is obtained. to the destruction of slugs.
The nitrochlorbenzenes can also be incorporated into a solid product such as glue or dextrin, with or without the addition of bran or sawdust, and the solid obtained is crushed and spread in the form of small pieces on the crops.
The use of these powders is much easier than that of acetaldehyde-based products because it is possible to operate by spreading or powdering.
The nitrochlorbenzenes can also be dissolved in a hydrocarbon which is, by known means, emulsified in water. The operation is then carried out by spraying.
In a laboratory test, on a patch of grass kept constantly moist and under a Lange-Welt bell, the powder is powdered with talc containing 10% o-nitrochlor-benzene, at a rate of 1 kg. per are, a mortality of 100 in a few hours for a population of 50 slugs per m2.
In an in-kind test in a cage, at a rate of 50 slugs per m2 and with a mixture containing 10% talc, 80% bran and 10% p-nitrochlorbenzene, used at a rate of 1 kg. by are, one obtains a mortality (the 100% in a few hours.
<Desc / Clms Page number 3>
In an identical test in nature in a cage, the same result is obtained using bran containing 10% of a mixture of 66% p-nitrochlorbenzene and 34% o-nitrochlorbenzene.
