Description
Verfahren zur Herstellung eines Pflanzenschutzmittels. Zur Bekämpfung von Pflanzenschädlingen -indet Kupfer in seinen verschiedenen Ver- oindungsformen ausgedehnte Verwendung. Es zeigte sich nun, dass die fungizide Wir kung, die es gegen Pilze, zum Beispiel gegen Peronospora viticolu <B>D.</B> By. der Reben, aus übt, eine wesentliche Steigerung erfährt, wenn es in Metall- oder Salzform mit-. Zink oder Zinksalzen kombiniert wird.
Gegenstand vorliegender Erfindung ist., auf Grund dieser neuen Erfahrung, ein Ver fahren zur Herstellung eines Pflanzenschutz mittels, gemäss welchem man Kapfersulfat- -und Zinksulfatlösungen miteinander mischt und das Lösungsgemisch mit alkalisch rea,- gierenden Substanzen behandelt, wodurch ein schwer löslicher Niederschlag erzeugt wird. Eine mit diesem Niederschlag hergestellte Spritzbrülie enthält die wirksamen Bestand teile in fein verteilt-er, schwer löslicher Form.
<I>Beispiel:</I> Man löst<B>75</B> gr Kupfersulfat (CiiSO, <B>- 5H,0)</B> und<B>75</B> gr Zinksulfat (ZÜSO, <B>- 711,0)</B> in <B>5</B> Liter Wasser auf. Ferner löscht man<B>125</B> gr frisch gebrannten Kalk, ergänzt zu<B>5</B> Litern, verrührt die Mischung zu einer gleichmässigen Kalkmilch und giesst die Kupferzinksulfat- lösung unter Umrühren in diese Kalkmilch. ein. Es fallen basisehe Kupferzinksalze in sehr fein verteilt Form aus.<B>--</B> Die auf obige Weise hergestellte Brühe ist ohne weiteres gebrauchsfertig.
Obgleich zur Herstellung der Brühe nur<B>0,75</B> '/o Kup fervitriol verwendet -wurden, kommt sie doch, wie durch Versuche festgestellt worden ist, in ihrer fungiziden Wirkung einer Kupfer- kalkbrühe gleich, zu deren Herstellung die doppelte Menge, das ist<B>1,5</B> '/o, Kupfervitriol gebraucht wurde. Durch die Kombination mit Zink lassen sicl-1 also<B>50</B> '/o Kupfer ersparen.
Da Zink und Zinkverbindungen nur schwache, in den meisten Fällen überhaupt keine pilztötenden Eigenschaften besitzen, so handelt es sieh im vorliegenden Falle nicht um die Summierun der Wirkung zweier Fungizide, sondern um einen Kombinations effekt, der nicht vorauszusehen war.
Neben der Wirkungssteigerung, deren Grund nicht et-,v-#7, in der feinen Verteilun- der Nieder- welplie die wirksamen Bestandteile enthalten, sondurn in der physikalischen Wechselwirkung zwischen dem Kupfersalz und Zinksalz, liegt, bringt das neue Verfahren n t' auch eine Verbilligung mit sieh, da. ein grosser Teil des teuren Kupfers durch das wohlfeile Zink ersetzt -werden kann.
Die erhaltenen Niederschläae von basiselien Kupferzinksalzen können abgesaugt und in Pastenform in den Handel ebraeht werden. Sie können zwecks Erzielung besserer Ver- sandfähio,keit auch -etrocknet und in die Form leicht in Wasser verteilbarer, feiner Pulver gebracht werden.

Process for the production of a plant protection product. In its various forms of compound, copper is used extensively for combating plant pests. It has now been shown that the fungicidal effect it has against fungi, for example against downy mildew viticolu <B> D. </B> By. the vine, exercising, experiences a substantial increase when it is in metal or salt form. Zinc or zinc salts is combined.
The present invention is, on the basis of this new experience, a process for the production of a plant protection agent, according to which caper sulfate and zinc sulfate solutions are mixed with one another and the mixed solution is treated with alkaline-reacting substances, which produces a sparingly soluble precipitate . A spray mixture produced with this precipitate contains the active components in finely divided, sparingly soluble form.
<I> Example: </I> Dissolve <B> 75 </B> gr copper sulfate (CiiSO, <B> - 5H, 0) </B> and <B> 75 </B> gr zinc sulfate (ZÜSO, <B> - 711.0) </B> in <B> 5 </B> liters of water. In addition, <B> 125 </B> gr of freshly burnt lime, add <B> 5 </B> liters, stir the mixture to form a uniform milk of lime and pour the copper zinc sulphate solution into this milk of lime while stirring. one. Basic copper zinc salts precipitate in a very finely divided form. <B> - </B> The broth prepared in the above manner is readily ready for use.
Although only 0.75% copper vitriol was used to make the broth, as has been established through experiments, its fungicidal effect is equivalent to a copper lime broth for its production double the amount, that is <B> 1.5 </B> '/ o, copper vitriol was used. By combining them with zinc, sicl-1 can save <B> 50 </B> '/ o copper.
Since zinc and zinc compounds have only weak, in most cases no fungicidal properties at all, the present case is not a matter of summing up the action of two fungicides, but a combination effect that could not be foreseen.
In addition to the increase in effectiveness, the reason for which is not the fine distribution of the active components but the physical interaction between the copper salt and zinc salt, the new process also brings one Discount with see, there. a large part of the expensive copper can be replaced by the cheaper zinc.
The precipitates of basic copper zinc salts obtained can be sucked off and sold in paste form. In order to achieve better dispatchability, they can also be dried and brought into the form of a fine powder that is easily dispersible in water.
