Als Zusätze eignen sich z. B. folgende Wirkstoffe: organische Phosphorverbindungen, Nitrophenole und Derivate, Pyrethroide, Formamidine, Harnstoffderivate, Carbamate, chlorierte Kohlenwasserstoffe.
Die Verbindungen der Formel I können zusammen mit geeigneten Trägern und/oder Zuschlagstoffen eingesetzt werden. Geeignete Träger und Zuschlagstoffe können fest oder flüssig sein und entsprechen den in der Formulierungstechnik üblichen Stoffen, wie z. B. natürlichen oder regenerierten Stoffen, Lösungs-, Dispergier-, Netz-, Haft-, Verdickungs-, Binde- und/oder Düngemitteln.
Zur Applikation können die Verbindungen der Formel I zu Stäubemitteln, Emulsionskonzentraten, Granulaten, Dispersionen, Sprays, zu Lösungen oder Aufschlämmungen in üblicher Formulierung, die in der Applikationstechnik zum Allgemeinwissen gehören, verarbeitet werden. Ferner sind cattle dips , d. h. Viehbäder, und spray races , d. h.
Sprühgänge, in denen wässerige Zubereitungen verwendet werden, zu erwähnen.
Die Herstellung erfindungsgemässer Mittel erfolgt in an sich bekannter Weise durch inniges Vermischen und/oder Vermahlen von Wirkstoffen der Formel I mit den geeigneten Trägerstoffen, gegebenenfalls unter Zusatz von gegenüber den Wirkstoffen inerten Dispergier- oder Lösungsmitteln.
Die Wirkstoffe können in den folgenden Aufarbeitungsformen vorliegen und angewendet werden: Feste Aufarbeitungsformen:
Stäubemittel, Streumittel, Granulate, Umhüllungsgranulate, Imprägnierungsgranulate und Homogengranulate; flüssige Aufarbeitungsformen: a) in Wasser dispergierbare Wirkstoffkonzentrate:
Spritzpulver (wettable powders), Pasten, Emulsionen; b) Lösungen.
Zur Herstellung fester Aufarbeitungsformen (Stäubemittel, Streumittel) werden die Wirkstoffe mit festen Trägerstoffen vermischt. Als Trägerstoffe kommen zum Beispiel Kaolin, Talkum, Bolus, Löss, Kreide, Kalkstein, Kalkgries, Attapulgit, Dolomit, Diatomeenerde, gefällte Kieselsäure, Erdalkalisilikate, Natrium- und Kaliumaluminiumsilikate (Feldspäte und Glimmer), Calcium- und Magnesiumsulfate, Magnesiumoxid, gemahlene Kunststoffe, Düngemittel, wie Ammoniumsulfat, Ammoniumphosphat, Ammoniumnitrat, Harnstoff, gemahlene pflanzliche Produkte, wie Getreidemehl, Baumrindenmehl, Holzmehl, Nussschalenmehl, Cellulosepulver, Rückstände von Pflanzenextrakten, Aktivkohle usw., je für sich oder als Mischungen untereinander in. Frage.
Granulate lassen sich sehr einfach herstellen, indem man einen Wirkstoff der Formel I in einem organischen Lösungsmittel löst und die so erhaltene Lösung auf ein granuliertes Mineral, z. B. Attapulgit, SiO2, Granicalcium, Bentonit usw., aufbringt und dann das organische Lösungsmittel wieder verdampft.
Es können auch Polymerengranulate dadurch hergestellt werden, dass die Wirkstoffe der Formel I mit polymerisierbaren Verbindungen vermischt werden (Harnstoff/Formaldehyd; Dicyandiamid/Formaldehyd; Melamin/Formaldehyd oder andere), worauf eine schonende Polymerisation durchgeführt wird, von der die Aktivsubstanzen unberührt bleiben, und wobei noch während der Gelbildung die Granulierung vorgenommen wird. Günstiger ist es, fertige, poröse Polymerengranulate (Harnstoff/Formaldehyd, Polyacrylnitril, Polyester und andere) mit bestimmter Oberfläche und günstigem voraus bestimmbarem Adsorptions-/Desorptionsverhältnis mit den Wirkstoffen z. B. in Form ihrer Lösungen (in einem niedrig siedenden Lösungsmittel) zu imprägnieren und das Lösungsmittel zu entfernen.
Derartige Polymerengranulate können in Form von Mikrogranulaten mit Schüttgewichten von vorzugsweise 300 bis 600 g/Liter auch mit Hilfe von Zerstäubern ausgebracht werden. Das Zerstäuben kann über ausgedehnte Flächen von Nutzpflanzenkulturen mit Hilfe von Flugzeugen durchgeführt werden.
Granulate sind auch durch Kompaktieren des Trägermaterials mit den Wirk- und Zusatzstoffen und anschliessendem Zerkleinern erhältlich.
Diesen Gemischen können ferner den Wirkstoff stabilisierende Zusätze und/oder nichtionische, anionaktive und kationaktive Stoffe zugegeben werden, die beispielsweise die Haftfestigkeit der Wirkstoffe auf Pflanzen und Pflanzenteilen verbessern (Haft- und Klebemittel) und/oder eine bessere Benetzbarkeit (Netzmittel) sowie Dispergierbarkeit (Dispergatoren) gewährleisten.
Beispielsweise kommen folgende Stoffe in Frage: Olein/ Kalk-Mischung, Cellulosederivate (Methylcellulose, Carboxymethylcellulose), Hydroxyäthylenglykoläther von Mono- und Dialkylphenolen mit 5-15 Äthylenoxidresten pro Molekül und 8-9 Kohlenstoffatomen im Alkylrest, Ligninsulfonsäure, deren Alkali- und Erdalkalisalze, Polyäthylenglykoläther (Carbowachse), Fettalkoholpolyglykoläther mit 5-20 Äthylenoxidresten pro Molekül und 8-18 Kohlenstoffatomen im Fettalkoholteil, Kondensationsprodukte von Äthylenoxid, Propylenoxid, Polyvinylpyrrolidone, Polyvinylalkohole, Kondensationsprodukte von Harnstoff/Formaldehyd sowie Latex-Produkte.
In Wasser dispergierbare Wirkstoffkonzentrate, d. h.
Spritzpulver (wettable powders), Pasten und Emulsionskonzentrate stellen Mittel dar, die mit Wasser auf jede gewünschte Konzentration verdünnt werden können. Sie bestehen aus Wirkstoff, Trägerstoff, gegebenenfalls den Wirkstoff stabilisierenden Zusätzen, oberflächenaktiven Substanzen und Antischaummitteln und gegebenenfalls Lösungsmitteln. Die Spritzpulver (wettable powders) und Pasten werden erhalten, indem man die Wirkstoffe mit Dispergiermitteln und pulverförmigen Trägerstoffen in geeigneten Vorrichtungen bis zur Homogenität vermischt und vermahlt. Als Trägerstoffe kommen beispielsweise die vorstehend für die festen Aufarbeitungsformen erwähnten in Frage. In manchen Fäl len ist es vorteilhaft, Mischungen verschiedener Trägerstoffe zu verwenden.
Als Dispergatoren können beispielsweise verwendet werden: Kondensationsprodukte von sulfoniertem Naphthalin und sulfonierten Naphthalinderviaten mit Formaldehyd, Kondensationsprodukte des Naphthalins bzw. der Naphthalinsulfonsäuren mit Phenol und Formaldehyd sowie Alkali-, Ammonium- und Erdalkalisalze von Ligninsulfonsäure, weiter Alkylarylsulfonate, Alkali- und Erdalkalimetallsalze der Dibutylnaphthalinsulfonsäure, Fettalkoholsulfate, wie Salze sulfatierter Hexadecanole, Heptadecanole, Octadecanole und Salze von sulfatierten Fettalkoholglykol äthern, das Natriumsalz von Oleylmethyltaurid, ditertiäre Äthylenglykole, Dialkyldilaurylammoniumchlorid und fettsaure Alkali- und Erdalkalisalze.
Als Antischaummittel kommen zum Beispiel Siliconöle in Frage. Die Wirkstoffe werden mit den oben aufgeführten Zusätzen so vermischt, vermahlen, gesiebt und passiert, dass bei den Spritzpulvern der feste Anteil eine Korngrösse von 0,02 bis 0,04 und bei den Pasten von 0,03 mm nicht überschreitet. Zur Herstellung von Emulsionskonzentraten und Pasten werden Dispergiermittel, wie sie in den vorangehenden Abschnitten aufgeführt wurden, organische Lösungsmittel und Wasser verwendet. Als Lösungsmittel kommen beispielsweise Alkohole, Benzol, Xylole, Toluol, Dimethylsulfoxid und im Bereich von 120 bis 350" C siedende Mineral ölfraktionen in Frage. Die Lösungsmittel sollen praktisch geruchlos und den Wirkstoffen gegenüber inert sein.
Ferner können die erfindungsgemässen Mittel in Form von Lösungen angewendet werden. Hierzu wird der Wirkstoff bzw. werden mehrere Wirkstoffe der allgemeinen Formel I in geeigneten organischen Lösungsmitteln, Lösungsmittelgemischen oder Wasser gelöst. Als organische Lösungsmittel können aliphatische und aromatische Kohlernvasser- stoffe, deren chlorierte Derivate, Alkylnaphthaline, Mineral öle allein oder als Mischung untereinander verwendet werden. Der Gehalt an Wirkstoff in den oben beschriebenen Mitteln liegt zwischen 0,1 bis 95%, dabei ist zu erwähnen, dass bei der Applikation aus dem Flugzeug oder mittels anderer geeigneter Applikationsgeräte Konzentrationen bis zu 99,5 % oder sogar reiner Wirkstoff eingesetzt werden können.

unter Rückfluss. Zur Aufarbeitung wird die Reaktionslösung vom Bodenkörper abfiltriert und das Filtrat im Vakuum vom Lösungsmittel befreit. Den Rückstand löst man in Äther-Hexan 1:3, wäscht diese Lösung viermal mit 10 %iger Natronlauge und anschliessend mit Wasser und Natriumchlorid-Lösung neutral. Nach dem Trocknen der organischen Phase über Natriumsulfat wird das Lösungsmittel im Vakuum vollständig abdestilliert und der Rückstand in n-Hexan umkristallisiert, wodurch farbloses l-Benzyl-4-(4'-methyl)benzyloxy-benzol vom Smp. 63-64 C erhalten wird.
