Verfahren zur Verbesserung der Verwendbarkeit insektieider Drogen.
Die direkte Verarbeitung insekticider Drogen zu staubförmigen und spritzbaren Pflanzenschutzmitteln stösst zumeist auf Schwierigkeiten, weil ein grosser Teil der wirksamen Stoffe von den Drogen festgehalten wird und deshalb nicht voll ausgenutzt werden kann. Man ging deshalb häufig zu Extraktionen der Drogen über, was aber eine erhebliche Verteuerung des Endproduktes verursachte.
Es wurde nun gefunden, dass man die wirksamen Bestandteile von Wurzeln, Rhizomen, Holz, grünen Pflanzenteilen, Blättern, Blüten, Samen dadurch freilegen und gegebenenfalls in Trägerstoffen fein verteilen kann, dass man sie mit in der Kälte festen Extraktionsmitteln verschmilzt Hiefür kommen je nach Art der angewandten Drogen alicyklische odercyklische Kohlenwasserstoffe, Terpene, anorganische Substanzen, wie krista11isiertes Natriumacetat, krista11isiertes Natriumsulfat oder Mischungen derselben in Frage.
Neben der höheren Wirksamkeit erreicht man durch dieses Verfahren auch wichtige physikalische Effekte, z. B. gut haftende, staubförmige Produkte, die auch in Wasser aufgeschlämmt als Spritzbrühe dank ihrer guten Sehwebefähigkeit Verwendung finden können.
Beispiel 1 : Tabakstaub wird mit der gleichen Menge Natriumacetat verschmolzen bis ein eingetauchtes Thermometer auf 110 steigt. Die gepulverte Schmelze kann als Stäube-und Spritzmittel Verwendung fmden.
Beispiel 2 : Derriswurzel wird im Verhältnis 3 : 5 mit Naphtol verschmolzen und mit geeigneten Verdünnungsmitteln, wie Talcum, vermahlen. Es entsteht ein gegen Raupen hochwirksames Produkt, das gleichzeitig fungieid ist.
Beispiel 3 : 25 Teile Rhizoma Veratri werden mit 60 Teilen Rohnaphthalin geschmolzen und nach dem Erkalten mit Tonerde vermahlen. Statt des Naphthalins lassen sich mit dem gleichen Erfolge Carbazol, Thymol, Isothymol und Rohanthracen verwenden.
Beispiel 4 : 50 Teile Asagraeasamen und 65 Teile Naphthalin werden miteinander verschmolzen und je nach dem zu bekämpfenden Insekt mit geeigneten Füllstoffen gestreckt.
Beispiel 5 : Pyrethrumblüten werden mit einem Drittel ihres Gewichtes an Naphthalin kurze Zeit unter intensiver Mahlung verschmolzen. Die Wirksamkeit gegen Insekten steigt dabei um etwa 25% an.
Beispiel 6 : Gleiche Teile Pyrethrum und Derriswurzel werden im Verhältnis 3 : 5 mit Naphthol verschmolzen und nach Beispiel 3 weiter verarbeitet.
Beispiel 7 : Quassiaholz wird mit kristallisiertem Borax verschmolzen. Das gepulverte Schmelzprodukt gibt ein spritzbares oder verstäubungsfähiges Pulver.

Process for improving the usability of insectic drugs.
The direct processing of insecticidal drugs into powdered and sprayable pesticides usually meets with difficulties because a large part of the active substances is retained by the drugs and therefore cannot be fully exploited. The drug was therefore often extracted, but this made the end product considerably more expensive.
It has now been found that the active components of roots, rhizomes, wood, green parts of plants, leaves, flowers, seeds can be exposed and, if necessary, finely distributed in carriers by fusing them with extractants that are solid in the cold.This depends on the species of the drugs used, alicyclic or cyclic hydrocarbons, terpenes, inorganic substances such as crystallized sodium acetate, crystallized sodium sulfate or mixtures thereof.
In addition to the higher effectiveness, this method also achieves important physical effects, e.g. B. well-adhering, dust-like products that can also be used as a spray liquor when suspended in water thanks to their good visual ability.
Example 1: Tobacco dust is fused with the same amount of sodium acetate until a submerged thermometer rises to 110. The powdered melt can be used as a dust and spray agent.
Example 2: Derris root is fused with naphtol in a ratio of 3: 5 and ground with suitable diluents such as talc. The result is a highly effective product against caterpillars that is also fungicidal.
Example 3: 25 parts of Rhizoma Veratri are melted with 60 parts of crude naphthalene and, after cooling, ground with clay. Instead of naphthalene, carbazole, thymol, isothymol and crude anthracene can be used with the same success.
Example 4: 50 parts of Asagraea seeds and 65 parts of naphthalene are fused together and, depending on the insect to be controlled, stretched with suitable fillers.
Example 5: Pyrethrum flowers are fused with a third of their weight in naphthalene for a short time with intensive grinding. The effectiveness against insects increases by about 25%.
Example 6: Equal parts of pyrethrum and derris root are fused with naphthol in a ratio of 3: 5 and processed further according to example 3.
Example 7: Quassia wood is fused with crystallized borax. The powdered melt product is a sprayable or atomizable powder.
