Gemäß dem Patent 817 057 wurde gefunden, daß ■die Phosphorsäurethiolester folgender Zusammensetzung :According to patent 817 057 it was found that ■ the phosphoric acid thiol ester of the following composition :

(R1 und R2 stehen für beliebige Alkylreste, R3 steht für einen beliebig· substituierten Arylrest) sich sehr gut zur Bekämpfung von saugenden und fressenden Insekten aller Art eignen. Die erfindungsgemäß als Schädlingsbekämpfungsmittel zu verwendenden Ester können nach an sich bekannten Verfahren(R 1 and R 2 stand for any alkyl radicals, R 3 stands for any substituted aryl radical) are very suitable for combating sucking and eating insects of all kinds. The esters to be used as pesticides according to the invention can be prepared by processes known per se

aus Dialkylthionophosphorsäuremonoehloriden und Thiophenolen in Gegenwart säurebkidender Mittel leicht erhalten werden. Gegenüber den den Gegenstand des Hauptpatents bildenden Phosphorsäureestern haben die neuen Thionophospho-rsaureester den Vorteil, daß sie gegen Warmblüter weniger giftig und geigen hydrolytische Einflüsse stabiler sind.from dialkylthionophosphoric acid monoehloriden and thiophenols in the presence of acidic agents can be easily obtained. Compared to the phosphoric acid esters forming the subject of the main patent the new thionophosphoric acid esters have the advantage that they are less effective against warm-blooded animals toxic and fiddle hydrolytic influences are more stable.

Folgende Beispiele mögen eine Übersicht über die ίο Wirkungsweise der neuen Verbindlungen geben:The following examples may give an overview of the ίο mode of operation of the new connections:
