Description
Unkrautvertilgungsmittel Die Erfindung betrifft Unkrautvertilgungsmittel und besonders solche, die sich dazu eignen, vor dem Auftreten des Unkrauts angewendet zu werden. Die erfindungsgemäßen Unkrautvertilgungsmittel sind kernchlorierte Phenoxyäthylphosphite mit den allgemeinen Formeln (ROC2H40)2P-OH und (ROC2H40)3P bei denen R einen chlorsubstituierten Phenylrest darstellt.Weedkillers The invention relates to weedkillers and especially those suitable to be applied prior to the appearance of the weeds to become. The weedkillers according to the invention are ring-chlorinated phenoxyethyl phosphites with the general formulas (ROC2H40) 2P-OH and (ROC2H40) 3P in which R is a chlorine-substituted one Represents phenyl radical.
Diese Verbindungen werden dadurch hergestellt, daß in an sich bekannter Weise 3 Mol eines kernchlorierten Phenoxyäthanols mit 1 Mol Phosphortrichlorid umgesetzt werden. Bei der Herstellung der Triester wird diese Reaktion in Gegenwart eines Säureakzeptors durchgeführt.These compounds are produced by being known per se Way 3 moles of a nuclear chlorinated phenoxyethanol reacted with 1 mole of phosphorus trichloride will. In the preparation of the Trieste this reaction occurs in the presence of a Acid acceptor carried out.
Die erfindungsgemäßen kernchlorierten Phenoxyäthylphosphite können als Unkrautvertilgungsmittel zum Verstäuben verwendet werden. Zu diesem Zweck werden sie mit einer pulverförmigen festen Trägersubstanz vermischt, z. B. mit Mineralsilikaten, wie Glimmer, Talk, Pyrophyllit oder Ton. Sie können jedoch auch zur Herstellung von Konzentraten dienen. Hierzu werden sie mit oberflächenaktiven Dispergierungsmitteln versetzt, um ihre Emulgierung in Wasser zu erleichtern und bei der Verwendung als Sprühmittel die Benutzungseigenschaften zu verbessern. Sie können jedoch auch mit der pulverförmigen festen Trägersubstanz und dem oberflächenaktiven Dispergierungsmittel vermischt werden. Man erhält dann ein netzbares Pulver, das direkt verwendet werden kann oder das mit Wasser aufgeschüttelt werden kann. Ebenso ist es möglich, die erfindungsgemäßen Verbindungen nach der Aerosolmethode zu verwenden.The nuclear chlorinated phenoxyethyl phosphites according to the invention can used as herbicides for dusting. Be for this purpose mixed with a powdery solid carrier, e.g. B. with mineral silicates, like mica, talc, pyrophyllite or clay. However, you can also use it to manufacture of concentrates serve. To do this, they are mixed with surface-active dispersants added to facilitate their emulsification in water and when used as a Spray to improve the usage properties. However, you can also use the powdery solid carrier substance and the surface-active dispersant be mixed. A wettable powder is then obtained which can be used directly or that can be shaken with water. It is also possible to use the to use compounds according to the invention by the aerosol method.
DieWirksamkeit derSubstanzen alsUnkrautvertilgungsmittel vor dem Auftreten des Unkrautes, d. h. wenn die Substanzen auf den Boden gebracht werden, ehe die Unkräuter herauskommen, wird im folgenden Beispiel dargestellt.The effectiveness of the substances as herbicides before they occur of weeds, d. H. when the substances are brought to the ground before the Weeds coming out is shown in the following example.
Beispiel Mischungen von je 40 mg der verschiedenen zu prüfenden Substanzen und 35 mg eines Dispergierungsmittels, welches nicht unkrautschädlich ist (ein Kondensationsprodukt aus Äthylenoxyd und einem alkylierten Phenol) wurden in 70 ccm Wasser dispergiert. Die Dispersionen der verschiedenen Substanzen werden auf die Erdoberfläche von einzelnen 15,2 cm großen Tontöpfen gegossen, unmittelbar nachdem sie mit einer Mischung von Samen von breitblättrigen und grasartigen Unkräutern besät worden waren. Das Anwendungsverhältnis der verschiedenen Substanzen war etwa 9,1 kg pro 0,4 ha. Kontrollversuche wurden mit einer wäßrigen Lösung gemacht, welche nur Wasser und das oberflächenaktive Mittel enthielt. Ähnliche Versuche in verringerten Anwendungsmengen der Substanzen wurden ausgeführt. Die ausgesäten Samen enthielten amaranthus ssp., setaria spp., digitaris spp., chenopodium spp., ambrosia spp., portulaca oleracea und galinsoga sp.Example mixtures of 40 mg each of the various substances to be tested and 35 mg of a dispersant which is not harmful to weeds (a condensation product from ethylene oxide and an alkylated phenol) were dispersed in 70 cc of water. The dispersions of the various substances are applied to the earth's surface by individuals 15.2 cm clay pots poured immediately after being mixed with Seeds of broad-leaved and grassy weeds had been sown. The application ratio of the various substances was about 9.1 kg per 0.4 ha. Control tests were made made with an aqueous solution containing only water and the surfactant contained. Similar attempts in reduced application amounts of the substances were made executed. The seeds sown contained amaranthus ssp., Setaria spp., Digitaris spp., chenopodium spp., ambrosia spp., portulaca oleracea and galinsoga sp.
Einen Monat nach dem Aussäen wurden die Proben hinsichtlich des Prozentsatzes der Unkrautvertilgung ausgewertet, und zwar getrennt für breitblättrige und grasartige Unkräuter, wobei 0 1, 1, Vernichtung den Unkrautbestand und 100 % Vernichtung das völlige Ausbleiben des Unkrautes bedeutet.One month after sowing, the samples were evaluated for the percentage of weed eradication, separately for broad-leaved and grassy weeds, where 0 1, 1 means destruction of the weed population and 100 % destruction means complete absence of weeds.
Tabelle I zeigt die Unkrautvernichtung der verschiedenen erfindungsgemäßen
Substanzen bei einer Anwendung von 9,1 kg pro 0,4 ha (20 pounds pro acre).
