Description

Es wurde gefunden, daß die Ester der Oxalsäure sowie ihre Derivate und Substitutionsprodukte ausgezeichnete Insektenvertilgungsmittel darstellen. Sie wirken bemerkenswerterweise sogar gegen die mit den bisherigen Mitteln schwer bekämpfbaren Museiden, wie z.B.musca domestica, stomoxys calcitrans usw. Ihre Anwendung erfolgt entweder mit den üblichen Streck- und Haftmitteln durch Verstäuben oder durch Verspritzen. ihrer Lösungen in organischen Lösungsmitteln bzw. ihrer auf beliebige Weise hergestellten wäßrigen Emulsionen. It has been found that the esters of oxalic acid and their derivatives and substitution products are excellent insecticides. They work remarkably even against the museids, who are difficult to fight with the previous means, such as e.g. musca domestica, stomoxys calcitrans etc. They are used either with the customary extenders and adhesives by dusting or spraying. of their solutions in organic solvents or their aqueous emulsions prepared in any way.

Den Estern lassen sich naturgemäß Zusätze anderer Insektizide geben; auch kann man mit ihnen wertvolle Insektizide enthaltende Naturprodukte, z. B. Pyrethrum, extrahieren und den Extrakt in obiger Weise verwenden. Schließlich lassen sich aus genannten Naturprodukten mit beliebigen Lösungsmitteln hergestellte Extrakte in Verbindung mit den Oxalsäureestern gebrauchen. Zweckmäßig gibt man den genannten Spritzmitteln zur Erhöhung ihrer Schwebefähigkeit noch einen ZusatzOf course, the esters can be given additions of other insecticides; also one can with them containing valuable insecticides natural products such. B. Pyrethrum, extract and use the extract in the above manner. Finally, from the named natural products Use extracts made with any solvent in conjunction with the oxalic acid esters. Appropriately there you can add an additive to the above-mentioned sprays to increase their ability to float

viskoser Öle, ζ. B. Paraffinöl u. dgl.viscous oils, ζ. B. paraffin oil and the like.

Die Ester wirken meist schon bei Anwendung sehr geringer Mengen sicher abtötend auf die zu bekämpfenden Insekten. So wird z. B. bei Verwendung des Oxalsäurediäthylesters in einer Menge von 1 bis 2 ecm, auf den cbm Raum berechnet, selbst bei Anwesenheit zahlreicher der bekanntlich widerstandsfähigen Fliegen eine völlige Abtötung erreicht. Ähnliche Wirkung zeigt auch beispielsweise ein Präparat, das durch Mischen eines Oxalsäureesters mit dem mittels eines beliebigen Lösungsmittels aus Pyrethrum hergestellten Extrakt erhalten wird.The esters usually have a certain killing effect even when very small amounts are used the insects to be controlled. So z. B. when using the oxalic acid diethyl ester in an amount of 1 to 2 ecm, on the cbm Space calculated, even with the presence of numerous of the well-known resilient ones Flies achieved a complete kill. A, for example, also has a similar effect Preparation obtained by mixing an oxalic acid ester with that using any solvent extract prepared from pyrethrum is obtained.

Zur Herstellung einer Emulsion, die besonders zur Bekämpfung von Blatt- und Blutlausen geeignet ist, verfährt man in folgender Weise.For the production of an emulsion, which is especially useful for combating aphids and aphids is suitable, proceed in the following manner.

Eine Mischung von 5 Teilen Oxälsäurediäthylester und 5 Teilen Butylalkohol versetzt man mit 15 Teilen Emulgierungsmittel, z. B. einer 5oprozentigen Lösung des Natronsalzes der Dibutylnaphthalinsulfosäure. Hierauf wird auf 100 Teile mit Wasser verdünnt. Eine etwa 2prozentige Lösung dieser Stammlösung ergibt die hervorragend wirkende Gebrauchslösung. In gleicher Weise wirken Oxalsäuredimethylester, Oxalsäuredipropylester usw.A mixture of 5 parts of diethyl oxalate and 5 parts of butyl alcohol is added with 15 parts of emulsifying agent, e.g. B. a 5% solution of the sodium salt of dibutylnaphthalene sulfonic acid. It is then diluted to 100 parts with water. One about 2 percent solution of this stock solution results in the outstanding working solution. Dimethyl oxalate, dipropyl oxalate, etc. have the same effect.

Gegenüber den für die Bekämpfung von Vorratsschädlingen verwendeten leicht flüchtigen Ameisensäureestern zeichnen sich die Oxalsäureester infolge ihrer Schwerflüchtigkeit durch eine wesentlich erhöhte Wirksamkeit aus. So sind z. B. die Oxalsäureester hervorragende Mittel gegen Blatt- und Blutläuse und insbesondere gegen Fliegen, gegen die die Ameisensäureester praktisch unwirksam sind.Compared to the volatile ones used for combating stored pests Formic acid esters distinguish the oxalic acid esters due to their low volatility by a significantly increased effectiveness. So are z. B. the oxalic acid esters excellent Agents against aphids and blood lice and especially against flies, against which the formic acid esters are practically ineffective.
