Description

blittel zur Bekämpfung von Insekten Es wurde gefunden, daß aromatische Verbindungen, welche mehr als einen Rhodaliirest enthalten, sich durch eine außerordentlich starke insektizide Wirkung auszeichnen. Diese Produkte haben den Vorteil, daß sie geruchlos sind, in der wirksamen Konzentration keine Schädigung auf Pflanzen und beim Menschen keine Reizwirkung auf die Schleimhäute ausüben. Die Verbindungen sollen für insektizide ZweUe und als Mottenschutzmittel Verwendung :finden. Sie können in -wäßriger Emulsion, in kolloidaler Form. als Streupulver oder in organischen Lösungsmitteln gelöst zur Anwendung gelangen. Auch können andere ähnlich wirkende Stoffe, Haft-, Netz- oder Streckungsmittel zugesetzt werden.agents for combating insects It has been found that aromatic Compounds which contain more than one rhodium residue are distinguished by an extraordinary characterized by a strong insecticidal effect. These products have the advantage of being are odorless, in the effective concentration no damage to plants and do not cause irritation to the mucous membranes in humans. The connections are supposed to for insecticidal purposes and as a moth repellent use: find. You can in -aqueous emulsion, in colloidal form. as sprinkling powder or in organic Solvents are used. Others can also act similarly Substances, adhesives, wetting agents or extenders are added.

Beispiel i i Gewichtsteil i-Methoxy-2-4-xylyldirhodanid der Formel: #hergestellt aus der entsprechenden Dihalogenverbindung durch Umsetzen mit Ammoniumrhodanid in alkoholischer Lösung Z,' Schmelzpunkt 7 1 bis 72", N # 11-,28 ()jo, herechnet ii,2o%) werden gelöst in 4 Gewichtsteilen Aceton, dem ein in Aceton lösliches Netzl-nittel, wie Seife, zugesetzt ist, und die Lös'ung mit Wasser auf iooo Gewichtsteile verdünnt. Die so entstandene Emulsion tötet schon in einer Konzentration von 0,2 bis o,30/lo des vorgena;nntein Rhodanids grüne Blattläuse an grünen Pflanz,en, wie Cenerarien, Gurken usw., völlig ab, ohne danid die zeigt Pflanze dagegen zu bei schädigen. gleicher Anwendung, Benzylrho' daß erst in einer iprozentigen Konzentration die Vernichtung der grünen Blattläuse, und zwar nur bis höchstens 8o #,o, erfolgt, wobei jedoch bereits Verbrennungserscheinungen an den Blättern auftreten. Daß das Ernulg#cruno,smittel hierbei keine insektizide Wirkung hatte, zeigten mehrfache Versuche. Selbst in einer Konzentration von 0,5 N fand keine Vernichtung der Insekten statt.Example ii Part by weight of i-methoxy-2-4-xylyldirhodanide of the formula: #Produced from the corresponding dihalogen compound by reaction with ammonium thiocyanate in alcoholic solution Z, ' melting point 7 1 to 72 ", N # 11-, 28 () jo, calculated ii, 2o%) are dissolved in 4 parts by weight of acetone, the one in acetone soluble wetting agent, such as soap, is added, and the solution is diluted to 100 parts by weight with water green plants, such as ceneraria, cucumbers, etc., completely from without damaging the plant on the other hand. Same application, Benzylrho 'that the destruction of green aphids only in a 1 percent concentration, and only up to a maximum of 80%, o takes place, however, already burning symptoms in the leaves occur. that the Ernulg # cruno smittel, this had no insecticidal activity, showed multiple attempts. Even at a concentration of 0.5 N was no destruction of the insect en place.

Beispiel 2 Analog dem Beispiel i läßt sich das 1-4-Dimethoxy-2-5-xylyldirhodanid der For-mel: (Schmelzpunkt 1730 N = 9,7 %, berechnet i o % ) verwenden.Example 2 The 1-4-dimethoxy-2-5-xylyldirhodanide of the formula : (Melting point 1730 N = 9.7%, calculated 10% ) .

Beispiel 3 0,5 Gewichtsteile des Umsetzungsproduktes aus 1-MetIlOxY-3-chlor-4-6-xylyldichlorid und Ammoniumrhoda,#nid werden, wie im Beisp.-,el i angegeben, auf iooo Gewichtsteile gelöst und zur Vernichtung von Blattläusen auf grünein Pflanzen verwendet. 'Die Wirkung des Produktes erreicht in dieser Konzentration die des Nikotins. So werden bei einer o, iprozentigen Konzentration ioo % der grünen Blattläuse auf Cenerarien, Gurken usw. abgetötet.Example 3 0.5 parts by weight of the reaction product of 1-MetIlOxY-3-chloro-4-6-xylyldichlorid and Ammoniumrhoda, # nid be as indicated in Ex .-, el i iooo solved in parts by weight and for the destruction of aphids on grünein Plants used. 'The effect of the product reaches that of nicotine in this concentration. For example, 100% of the green aphids on ceneraria, cucumbers, etc. are killed at a concentration of 0.1%.
