Die Ausgangsprodukte zur Herstellung der Verbindungen sind an sich bekannt oder lassen sich nach an sich bekannten Verfahren herstellen.The starting products for making the compounds are in themselves known or can be produced by processes known per se.
Aus den folgenden Brjispiolen geht die herbizide Wirkung der erfindungsgemäßen Verbindungen im Vergleich zu bekannten Herbiziden hervor.The herbicidal action of the invention results from the following brjispiolen Compounds compared to known herbicides.
B e i s p i e l 1 Im Gewächshaus wurden die in nachstehender Tafel je aufgeführten Testptlanzen im Vorauflaufverfahren mit den erfindungsgemäß zu verwendenden Mitteln in einer Dosierung von 3 kg Wirkstoff/ha behandelt. Die Mittel wurden als wäßrige Suspension in 500 Liter gleichmäßig gespritzt.EXAMPLE 1 In the greenhouse, those in the table below were used each listed test plants in the pre-emergence process with those to be used according to the invention Agents treated in a dosage of 3 kg active ingredient / ha. The funds were called aqueous suspension sprayed evenly in 500 liters.
Die Befunde zeigen, daß die erfindungsgemäßen Mittel ein breites Wirkungsspektrum
aufweisen.
Nach dem Auflaufen der Hirse- und Reispflanzen wurde deren Entwicklung bis zum 2- bis 3-13lattstadium - abgewartet. Danaoh wurden die Töpfe 6 cm tief unter Wasser gesetzt, so daß die Hirse-und Reispflanzen zu einem mehr oder weniger großen Teil unter Wasser standen. Nach dem Überfluten erfolgte eine Flächenspritzung mit den aufgeführten Wirkstoffen in einer Aufwandmenge von 1 kg wirkstof/ha. suspendiert bzw. gelöst in 500 Liter Wasser/ ha. Auch nach der Spritzung wurde die Uberflutung bis zum Versuchsende beibehalten. 2 Wochen nach der Behandlung wurde der Schädigungsgrad der Pflanzen festgestellt und nach dem Bewertungsschlüssel O - 10 mit 0 = "total vernichtet und 10 = "nicht geschädigt" bonitiert.After the millet and rice plants emerged, their development began up to the 2- to 3-13 leaf stage - waited. Danaoh were the pots 6 inches deep under Water set so that the millet and rice plants become more or less large Were partly under water. After the flooding, the surface was also sprayed the listed active ingredients at an application rate of 1 kg active ingredient / ha. suspended or dissolved in 500 liters of water / ha. The flooding was also carried out after the spraying retained until the end of the experiment. 2 weeks after the treatment, the degree of damage was of the plants and according to the evaluation key O - 10 with 0 = "total destroyed and rated 10 = "not damaged".
Wie aus nachstehender Tabelle ersichtlich wird, zeigten sich die erfindungsgemäßen Verbindungen in der herbiziden Wirkung auf Hirse und in der Verträglichkeit für Reis vergleichend geprüften Standardmitteln als deutlich überlegen.As can be seen from the table below, those according to the invention were found Compounds in the herbicidal effect on millet and in the tolerance for Rice comparatively tested standard means as clearly superior.
