bedeuten, wobei A die Bedeutung von Wasserstoff, Phenyl- oder Eitrophenyl besitzt, sowie die cyclischen Phosphatester der Formel I als solche.mean, where A is hydrogen, phenyl or Eitrophenyl and the cyclic phosphate esters of the formula I as such.
Die erfindungsgemäßen cyclischen Phosphatester der allgemeinen Formel I sind bisher aus der Literatur nicht bekannte neue chemische Verbindungen und besitzen bemerkenswerte insektizide Wirksamkeit, eine synergistische Wirkung mit Malathion und nematozide Wirksamkeit.The cyclic phosphate esters according to the invention of the general Formula I are new chemical compounds not previously known from the literature and have a remarkable insecticidal activity, a synergistic effect with malathion and nematocidal effectiveness.
Die erfindungsgemäß cyclischen Phosphatester haben bemerkenswerte insektizide Wirksamkeit gegenüber verschiedenen Arten von schädlichen Insektenund Iiematoden, wit sich aus den unten angegebenen Prüfungsergebnissen ergibt, lieben der Insektiziden Wirksamkeit ist der Synergismus mit Halathion ein weiteres Kennzeichen der erfindungsgemäßen Verbindungen. Malathion, S- /ΓΛ , 2-Bis-(äthoxyearbohyl)-äthyj7 -ö,O-dimethylphosphorodithionat, ist ein bekanntes und im Handel verfügbares Insektizid. Die Resistenz von schädlichen Insekten von fteispflanzen gegen Malathion entwickelt sich jedoch zu einem schweren Problem. Bei Anwendung der erfindungsgemäßen Verbindung in Kombination mit Malathion können selbst malathionresisterite Schadinsekten mit hoher Wirksamkeit vernichten werden. Hinsichtlich der nematoziden Wirkung sind die erfindungsgemäßen cyclische^. Phosphatester wirksamer als D-I)1 das ein bekanntes Nematozid auf der-Basis von halogenierten Kohlenwasserstoffen ist, und sind v/irksam für die Bekämpfung der Weißspitzenkrankheit von Reispflanzen (white tip of rice plants) durch Behandlung von Heissaatgut. Dies ist ein weiteres Kennzeichen der Erfindung.'The cyclic phosphate esters according to the invention have remarkable insecticidal activity against various kinds of harmful insects and Iiematoden, wit it emerges from the test results given below, love of the insecticidal activity, the synergism with halathion is another characteristic of the compounds according to the invention. Malathion, S- / ΓΛ , 2-bis (äthoxyearbohyl) -äthyj7 -ö, O-dimethylphosphorodithionat, is a known and commercially available insecticide. However, malathion resistance of pest insects from frozen plants is becoming a serious problem. When the compound according to the invention is used in combination with malathion, even malathion-resistant insect pests can be destroyed with high effectiveness. With regard to the nematocidal effect, the cyclic ^ according to the invention. Phosphate esters more effective than DI) 1 which is a known nematocide based on halogenated hydrocarbons, and are effective for combating white tip of rice plants by treating hot seed. This is another feature of the invention. '
