Bewertungstest über milbentötende WirkungEvaluation test on miticide effect
Die 2-Punkt-Milbe, Tetranychus telarius (Linn.), wird in den Testverfahren für milbentötende Mittel verwendet. Junge »Pinto«-Bohnenpflanzen werden mit mehreren hundert Milben infiziert. Dispersionen der zu untersuchenden Verbindungen werden hergestellt, indem man 0,1 g des toxischen Stoffes in 10 ecm Aceton löst. Darauf wird diese Lösung mit Wasser verdünnt, in dem 0,015% des Natriumsalzes des Isopropylnaphthalinsulfonats und 0,005% methylierte Zellulose als Emulgiermittel enthalten sind; die Wassermenge wird so bemessen, daß die Konzentrationen des aktiven Bestandteiles zwischen 0,25 und 0,005% liegen. Diese Testsuspensionen werden dann auf die infizierten Pinto-Bohnenpflanzen gespritzt. Nach 7 und nach 14 Tagen werden die Pflanzen sowohl auf nachembryonale Formen der Milben als auch auf Eier untersucht. Der Prozentsatz der vernichteten Tiere wird durch Vergleich mit Kontrollpflanzen, die nicht gespritzt worden waren, ermittelt, der LDso-Wert wird unter Anwendung bekannter Verfahren errechnet. Die LDso-WerteThe 2-point mite, Tetranychus telarius (Linn.), Is used in the testing procedure for miticides used. Young "pinto" bean plants are infected with several hundred mites. Dispersions of the compounds under investigation are prepared by adding 0.1 g of the toxic substance in 10 ecm of acetone dissolves. This solution is then diluted with water containing 0.015% of the sodium salt the isopropyl naphthalene sulfonate and 0.005% methylated cellulose are included as emulsifying agents; the amount of water is calculated so that the concentrations of the active ingredient between 0.25 and 0.005%. These test suspensions are then applied to the infected pinto bean plants injected. After 7 and after 14 days, the plants are both on postembryonic forms of the Both mites and eggs were examined. The percentage of animals destroyed is determined by comparison with Control plants that had not been sprayed, the LD 50 value is determined using calculated using known methods. The LDso values

Bewertungstest über insektentötende WirkungEvaluation test for insecticidal effect
Vier Arten von Insekten wurden dem Bewertungstest für Insektizide unterworfen: Four kinds of insects were subjected to the insecticide evaluation test:
1. Amerikanische Küchenschabe (AKS),

4. Küchenfliege (KF),4. Kitchen fly (KF),
Musca domestica (Linn.).Musca domestica (Linn.).
Das bei Insekten angewendete Verfahren stimmt mit dem Testverfahren für Milben überein. Die Versuchsinsekten werden in zum Postversand verwendete Papprohre (Durchmesser 7,9 cm, Länge 6,7 cm) eingesperrt. Die Käfige erhalten Zellophanböden und durchlöcherte Deckel. In jeden Käfig werden zehn bis fünfundzwanzig Insekten gesetzt.The procedure used for insects is the same as the test procedure for mites. the Test insects are placed in cardboard tubes (diameter 7.9 cm, length 6.7 cm) imprisoned. The cages have cellophane bottoms and perforated lids. In every cage ten to twenty-five insects are placed.
Go Jeder Käfig erhält Nahrung und Wasser. Die falschen Mehlkäfer werden ohne Nahrung in Petrischalen gebracht. Die eingesperrten Insekten werden mit der aktiven Verbindung in verschiedenen Konzentrationen besprüht. Nach 24 und 72 Stunden werden die lebenden und toten Insekten ausgezählt.Go Each cage receives food and water. The wrong ones Flour beetles are placed in petri dishes without food. The caged insects are with the active compound sprayed in different concentrations. After 24 and 72 hours will be the living and dead insects are counted.

löst, die aktive Verbindung wird auf den Boden einer Petrischale pipettiert, man läßt sie an der Luft trocknen und stellt sie dann in ein solches Papprohr. Fünfundzwanzig weibliche Fliegen werden in das Rohr eingesperrt. Die Fliegen werden dem bekannten Rückstand der aktiven Verbindung in dem Käfig ständig ausgesetzt. Nach 24 und 48 Stunden werden die lebenden und toten Insekten ausgezählt. Die LD50-Werte werden nach bekannten Verfahren ermittelt, sie sind in der nachstehenden Tabelle aufgeführt.dissolves, the active compound is pipetted onto the bottom of a Petri dish, it is left in the air dry and then put them in such a cardboard tube. Twenty-five female flies are in that Locked pipe. The flies will keep the known residue of the active compound in the cage exposed. After 24 and 48 hours, the live and dead insects are counted. The LD50 values are determined by known methods, they are listed in the table below.

Die Umsetzung wird durch Verwendung bestimmter Katalysatoren erleichtert, wie tert.Amine, z. B. Pyridin, Trialkylamine, z. B. Trimethylamin, Trräthylamin und durch Polymerisationsinhibitoren, wie Hydrochinon und dessen alkylierte Derivate, besonders die, die Alkylgruppen in den 2,4-Stellungen enthalten; für die Durchführung der Umsetzung erwiesen sich leicht erhöhte Temperaturen ebenfalls als günstig.The implementation is facilitated by using certain catalysts, such as tertiary amines, e.g. B. Pyridine, trialkylamines, e.g. B. trimethylamine, triethylamine and polymerization inhibitors, such as hydroquinone and its alkylated derivatives, especially those having the alkyl groups in the 2,4-positions contain; Slightly elevated temperatures were also found to carry out the reaction as cheap.
Wendet man die Additionsmethode eines Dithiophosphonsäuremonoesters an Äthylendicarbonsäureester an, so ist die Gegenwart einer Base vorteilhaft; als Beispiel wird hier ebenfalls auf die bereits erwähnten tertiären Amine verwiesen. Unabhängig von dem im einzelnen Fall angewandten Herstellungsverfahren erwies sich die Verwendung eines organisehen Lösungsmittels als vorteilhaft, sehr geeignet in diesem Zusammenhang sind die flüssigen aromatischen Kohlenwasserstoffe, z. B. Benzol, Toluol, Xylol, Methylnaphthalin.If the addition method of a dithiophosphonic acid monoester is used on ethylenedicarboxylic acid ester, the presence of a base is advantageous; as an example, reference is also made here to those already mentioned tertiary amines. Regardless of the manufacturing process used in the individual case The use of an organic solvent proved to be advantageous, very suitable in this context the liquid aromatic hydrocarbons, e.g. B. benzene, toluene, Xylene, methylnaphthalene.

15,5 g Thioäpfelsäurediäthylester, 13,0 g Äthylthiophosphonsäurechlorid-O-äthylester, 60 ecm Aceton und 70 ecm Benzol wurden in einen Kolben gebracht, '5 der mit einem Rückflußkühler, einem Tropftrichter, einem Rührwerk und einem Thermometer versehen war. Unter gründlichem Rühren wurden 8,0 g Triäthylamin tropfenweise zugefügt; es trat eine sofortige Umsetzung ein mit gleichzeitiger Ausfällung des ^o Aminhydrochlorids. Nachdem die Zugabe beendet war, wurde das Reaktionsgemisch 30 Minuten unter Rückfluß erhitzt. Nachdem es auf Raumtemperatur abgekühlt worden war, wurde das Aminsalz abfiltriert, das Filtrat wurde, nachdem es mit 70 ecm Benzol gemischt worden war, mit Wasser, 3°/oiger wäßriger Natriumhydroxydlösung und wieder mit Wasser gewaschen. Das Filtrat wurde mit wasserfreiem Magnesiumsulfat getrocknet und darauf das Lösungsmittel im Vakuum entfernt. Es wurde ein fast farbloser öliger Rückstand gewonnen.15.5 g of thio malic acid diethyl ester, 13.0 g of ethylthiophosphonic acid chloride-O-ethyl ester, 60 ecm of acetone and 70 ecm of benzene were placed in a flask, '5 which is provided with a reflux condenser, a dropping funnel, a stirrer and a thermometer was. 8.0 g of triethylamine were added dropwise with thorough stirring; there was an immediate one Implementation with simultaneous precipitation of the ^ o amine hydrochloride. After the addition is over the reaction mixture was refluxed for 30 minutes. After it's at room temperature had been cooled, the amine salt was filtered off, the filtrate after it was at 70 ecm Benzene had been mixed with water, 3% aqueous sodium hydroxide solution and again with Water washed. The filtrate was dried with anhydrous magnesium sulfate and then the Solvent removed in vacuo. An almost colorless oily residue was obtained.
