Description
Utilisation dans la lutte contre les acariens, de sulfure de benzyle et de p-chlorophényle L'invention se rapporte à l'utilisation pour la lutte contre les acariens, à l'état d'aeufs, de larves ou d'animaux parfaits, sur la végétation, de sulfure de benzyle et de p-chlorophényle.
L'invention est basée sur la découverte que le sulfure de benzyle et de p-chlorophényle possède des propriétés acaricides et est effi cace pour la lutte contre les mites (Acariens) à l'état d'aeufs et de larves aussi bien qu'à l'état adulte, en particulier contre les Tétrany- chidés ou araignées rouges se nourrissant de plantes, par exemple le Tetranichus telarius L et le Metatetranychus ulmi Koch.
Selon la pré sente invention, on utilise donc pour la lutte contre les acariens, à l'état d'oeufs, de larves ou d'animaux adultes, sur la végétation, comme ingrédient actif, du sulfure de benzyle et de p-chlorophényle.
On peut utiliser, pour exécuter l'invention, des préparations qui peuvent être à l'état de poudre, de dispersion, d'émulsion, etc.
Dans les dispersions, l'ingrédient actif forme une phase solide dispersée et il est en combinaison avec un agent de dispersion et/ou un agent de suspension en milieu aqueux. Pour en faciliter la préparation l'ingrédient ac tif peut être mélangé préalablement à un agent de dispersion et/ou à un agent de suspension, de façon qu'une dispersion soit formée, lorsque le mélangé est ajouté à de l'eau ; la préparation à diluer peut aussi contenir un solvant orga nique miscible à l'eau, tel que l'acétone.
Les dispersions susceptibles d'être employées peu vent se présenter également sous forme de sus pensions dans lesquelles la phase solide dis persée est mélangée à une émulsion d'huile aqueuse, l'ingrédient actif étant insoluble dans l'huile, qui est, de préférence, une huile non volatile, par exemple de la paraffine liquide.
Dans les émulsions, la phase dispersée est formée par une solution de l'ingrédient ac tif, en combinaison avec un agent émulsion nant, dans un solvant organique, tel que le xy- lène ou un solvant aromatique bouillant entre 80 et 3000 C. Il peut être avantageux qu'elles comprennent encore une huile minérale ou vé gétale non volatile, telle que la paraffine liqui de, qui agit comme activant et/ou agent de fixation. L'émulsion peut aussi contenir un agent mouillant.
Pour en faciliter la prépara tion, l'ingrédient actif peut être préalablement mélangé à ou dissous dans un solvant organi que, tel que spécifié plus haut, ainsi qu'un agent émulsionnant et, si on le désire, un agent mouillant, de sorte qu'une émulsion soit for mée lorsque le mélange est incorporé à de l'eau. Les émulsions et dispersions aqueuses, décrites dans le présent mémoire, peuvent être diluées à l'eau avant application, de manière à obtenir une concentration finale en ingré dient actif, comprise entre 0,01 et 10,0 % poids/volume.
Des dispersions d'ingrédient actif dans les quelles la base est un diluant pulvérulent solide, peuvent également être utilisées.
On donne ci-après des exemples de prépa rations que l'on peut utiliser en conformité avec l'invention <I>Exemple 1</I> Pour préparer une émulsion, on dissout une quantité suffisante de sulfure de benzyle et de p-chlorophényle dans une solution obtenue en mélangeant 10 parties en poids de Inséra 108 (marque commerciale désignant un agent émulsionnant non ionique)
et 90 parties en poids de benzène pour donner une solution finale contenant 20 % (poids/volume) d'ingré- dient actif. On peut diluer le liquide huileux avec de l'eau pour former une émulsion stable.

Use in the fight against mites, of benzyl sulphide and p-chlorophenyl The invention relates to the use for the control of mites, in the state of eggs, larvae or perfect animals, on vegetation, benzyl sulfide and p-chlorophenyl.
The invention is based on the discovery that benzyl p-chlorophenyl sulfide possesses acaricidal properties and is effective for the control of moths (Mites) in the state of eggs and larvae as well as the adult state, in particular against Tetranychidae or red spider mites which feed on plants, for example Tetranichus telarius L and Metatetranychus ulmi Koch.
According to the present invention, therefore, for the control of mites, in the form of eggs, larvae or adult animals, on vegetation, as active ingredient, benzyl and p-chlorophenyl sulfide is used.
Preparations which may be in the form of powder, dispersion, emulsion, etc. can be used for carrying out the invention.
In dispersions, the active ingredient forms a dispersed solid phase and is in combination with a dispersing agent and / or an aqueous suspending agent. To facilitate the preparation thereof, the active ingredient may be premixed with a dispersing agent and / or a suspending agent, so that a dispersion is formed, when the mixture is added to water; the preparation to be diluted may also contain an organic solvent miscible with water, such as acetone.
The dispersions which can be employed can also be presented in the form of suspensions in which the dispersed solid phase is mixed with an aqueous oil emulsion, the active ingredient being insoluble in oil, which is preferably , a non-volatile oil, for example liquid paraffin.
In emulsions, the dispersed phase is formed by a solution of the active ingredient, in combination with an emulsifying agent, in an organic solvent, such as xylene or an aromatic solvent boiling between 80 and 3000 C. It may be advantageous if they further comprise a non-volatile mineral or vegetable oil, such as liquid paraffin, which acts as an activator and / or fixing agent. The emulsion can also contain a wetting agent.
To facilitate preparation, the active ingredient may be premixed with or dissolved in an organic solvent, as specified above, together with an emulsifying agent and, if desired, a wetting agent, so that An emulsion is formed when the mixture is incorporated into water. The aqueous emulsions and dispersions, described in the present specification, can be diluted with water before application, so as to obtain a final concentration of active ingredient of between 0.01 and 10.0% weight / volume.
Dispersions of the active ingredient in which the base is a solid powdery diluent can also be used.
Examples of preparations which can be used in accordance with the invention are given below. <I> Example 1 </I> To prepare an emulsion, a sufficient quantity of benzyl and p-chlorophenyl sulphide is dissolved. in a solution obtained by mixing 10 parts by weight of Inséra 108 (trade mark designating a nonionic emulsifying agent)
and 90 parts by weight of benzene to give a final solution containing 20% (weight / volume) of active ingredient. The oily liquid can be diluted with water to form a stable emulsion.
<I> Example 2 </I> To prepare a dispersible powder, the following ingredients are intimately mixed. Benzyl and p-chlorophenyl sulfide. . . . . . . . 20 Belloid T D parts (commercial designation of a dispersing agent). . . . . . . . . 8 Kaolin parts. . . . . . . . . 72 parts <I> Example 3 </I> An acaricidal powder is prepared by intimately mixing the following ingredients Benzyl and p-chlorophenyl sulfide. . . . . . . .
