Description

Bekämpfung von Pflanzenschädigungen hervorrufenden Insekten und ihrer Entwicklungsstadien Durch Umsetzung von Mercurisalzen mit Olefinen, z. B. Äthylen, in Gegenwart einer organischen Verbindung mit aktivem Wasserstoff, z. B. Methanol oder Eisessigsäure, lassen sich leicht Quecksilberadditionsverbindungen gewinnen. Derartige Verbindungen besitzen gute fungizide und bakterizide Wirksamkeit; sie werden vor allem als Saatgutbeizen eingesetzt. Für andere Zwecke einer Pflanzenbehandlung wurden sie bisher nicht verwendet, da hier ihr Einsatz nicht als aussichtsreich erschien.Control of insects causing damage to plants and their Stages of development By reacting mercury salts with olefins, e.g. B. Ethylene, in the presence of an organic compound containing active hydrogen, e.g. B. methanol or glacial acetic acid, mercury addition compounds can easily be obtained. Such compounds have good fungicidal and bactericidal activity; she are mainly used as seed dressing. For other plant treatment purposes they have not been used up to now, as their use is not promising here appeared.

Es wurde nun gefunden, daß die genannten Quecksitberadditionsverbindungen entgegen der bisherigen Meinung gute Mittel zur Bekämpfung von Pflanzenschädigungen hervorrufenden Insekten oder Raupen sind. Insbesondere sind zu diesen Zwecken auch die bisher nur als Saatgutbeizen eingesetzten Verbindungen, zu deren Herstellung einfache Alkohole, wie Methanol oder Äthanol, sowie niedrige Olefine, wie Äthylen, Propylen oder auch Styrol, dienen, geeignet.It has now been found that the mercury addition compounds mentioned contrary to previous opinion, good means of combating plant damage causing insects or caterpillars. In particular, for these purposes too the compounds previously only used as seed dressing, for their production simple alcohols such as methanol or ethanol, as well as lower olefins such as ethylene, Propylene or styrene, are suitable.

Es können aber auch andere Verbindungen mit aktivem Wasserstoff zum Einsatz gebracht werden, z. B. Carbonsäuren, Phenole oder Amine. Als Quecksilbersalze eignen sich z. B. recht gut Mercuriacetat oder Mercurichlorid. Als Beispiele für derartige Verbindungen seien genannt Es kann selbstverständlich in bestimmten Fällen zweckmäßig sein, verschiedene Quecksilberadditionsverbindungen, z. B. eine solche mit Äthylenkomponente und eine solche mit Propylenkomponente, gemeinsam z. B. in einem flüssigen Medium emulgiert, anzuwenden. in an sich bekannter Weise gewonnen, wurde einem hochmolekularen farblosen flüssigen Fettalkohol (bekannt unter dem gesetzlich geschützten Warenzeichen »Eutanol«) gelöst, mit absolutem Alkohol und einem Emulgator versetzt und das Gemisch in ein Ölgemisch aus gleichen Teilen Gasöl (Siedebereich 300 bis 340°C) und Schwerbenzin (Siedebereich 150 bis 180°C) gegeben, so daß eine Lösung folgender Zusammensetzung entstand Methoxyphenyläthylquecksilber- chlorid ........................ 7,5 g Hochmolekularer Fettalkohol ....... 20,0 g Absoluter Alkohol . . . . . . . . . . . . . . . . 12,5 g Emulgator . . . . . . . . . . . . . . . . . . . . . . . 10,5 g Ölgemisch . . . . . . . . . . . . . . . . . . . . . . . . 49,5 g Durch Emulgieren mit Wasser wurde eine in bezug auf den Wirkstoff 0,05 °/jge Emulsion hergestellt. Diese tötete, auf die befallene Pflanze gesprüht, Kiefernschwärmerlarven im vierten Stadium am sechsten Tag und Kiefernspannerlarven im dritten Stadium am vierten Tag voll ab.However, other compounds with active hydrogen can also be used, e.g. B. carboxylic acids, phenols or amines. As mercury salts are z. B. quite good mercuric acetate or mercuric chloride. Examples of such compounds may be mentioned It may of course be useful in certain cases to use various mercury addition compounds, e.g. B. one with ethylene component and one with propylene component, together z. B. emulsified in a liquid medium, apply. Obtained in a known manner, a high molecular weight colorless liquid fatty alcohol (known under the legally protected trademark "Eutanol") was dissolved, mixed with absolute alcohol and an emulsifier and the mixture was converted into an oil mixture of equal parts of gas oil (boiling range 300 to 340 ° C ) and heavy gasoline (boiling range 150 to 180 ° C) added, so that a solution of the following composition was formed Methoxyphenylethylmercury chloride ........................ 7.5 g High molecular weight fatty alcohol ....... 20.0 g Absolute alcohol. . . . . . . . . . . . . . . . 12.5 g Emulsifier. . . . . . . . . . . . . . . . . . . . . . . 10.5 g Oil mixture. . . . . . . . . . . . . . . . . . . . . . . . 49.5 g By emulsifying with water, an emulsion of 0.05% / yg with respect to the active ingredient was produced. Sprayed on the infested plant, this completely killed pine hawk larvae in the fourth stage on the sixth day and pine moth larvae in the third stage on the fourth day.
