Description

       

  Mittel zur     Beeinflussung    des     Pflanzenwachstums,    insbesondere     zur    Bekämpfung von Unkraut    Es hat sich überraschenderweise gezeigt, dass       Triazine    der Formel  
EMI0001.0005     
    worin  X Sauerstoff oder Schwefel  n 0 oder 1  R,     R1,        R2,        R3    und R4 Wasserstoff oder     Kohlen-          wasserstoffreste     bedeuten, bereits in sehr niedriger Konzentration auf  Pflanzen wachstumshemmend und abtötend wirken.  Verbindungen der oben definierten Formel 1 sind  z.

   B. durch Umsetzung von     Cyanurchlorid    mit ge  eigneten Alkoholen oder     Mercaptanen    und Aminen,  gegebenenfalls gefolgt von reduktiver Entfernung  eines noch verbliebenen Chloratoms     herstellbar,     ferner durch Umsetzung von 2-Alkyl-4,6-dichlor-s-         triazinen    mit     Aminen.    Sie eignen sich     vorzüglich    als  Wirkstoffe für     Unkrautbekämpfungsmittel,    sowohl  zur selektiven     Abtötung    von Unkräutern unter Kul  turpflanzen wie auch zur totalen     Abtötung    und  Verhinderung unerwünschten Pflanzenwuchses. Unter  Unkräutern werden hierbei auch unerwünschte,  z.

   B. vorher oder in der Nähe angebaute Kultur  pflanzen verstanden. Die oben definierten Verbin  dungen eignen sich weiterhin auch als Wirkstoffe  für andere hemmende Beeinflussungen des Pflanzen  wachstums, insbesondere     Entblätterung,    Reifebe  schleunigung durch Verminderung des Frucht  ansatzes, Verzögerung der Blüte.  



  Als     Wirkstoffe        kommen    z. B. die nachstehenden,  zum Teil bekannten, zum Teil neuen     Triazinderivate     in Frage:-

   B. Äthyl- oder     Isopropylalkohol,        Ketone,    wie  Aceton oder     Cyclohexanon,        aliphatische    Kohlen  wasserstoffe, wie     Kerosen    und     cyclische    Kohlen  wasserstoffe, wie Benzol,     Toluol,        Xylol,        Tetrahydro-          naphthalin,        alkylierte        Naphthaline,        ferner    chlorierte       Kohlenwasserstoffe,    wie     Tetrachloräthan,

      Äthylen  chlorid und endlich auch     mineralische    und pflanz  liche Öle oder Gemische der     obengenannten    Stoffe       in    Frage. Insbesondere bei der totalen     Abtötung    von  Pflanzenwuchs, bei der vorzeitigen Austrocknung so-    wie der     Entblätterung        kann    die Wirkung durch die  Verwendung von an sich     phytotoxischen    organischen  Flüssigkeiten, wie z. B. hochsiedenden Mineralöl  fraktionen oder     Chlorkohlenwasserstoffen,    verstärkt  werden; anderseits kommt die Selektivität der  Wachstumshemmung bei der Verwendung von ge  genüber Pflanzen indifferenten Trägerstoffen, z. B.

    in der selektiven Unkrautbekämpfung, unter Umstän  den deutlicher zur Geltung.  



  Die verschiedenen     Wirkstofflösungen    können in       üblicher    Weise durch Zusatz von Stoffen, welche  die     Verteilung,    die Haftfestigkeit, die Regenbestän-           digkeit    und     evtl.    das     Eindringungsvermögen    verbes  sern, wie z. B. Fettsäuren oder Harzen den Verwen  dungszwecken näher angepasst werden. Ebenso lässt  sich ihre biologische Wirkung verbreitern durch Zu  satz von Stoffen mit bakteriziden Fungiziden oder       ebenfalls    das Pflanzenwachstum beeinflussenden  Eigenschaften.  



  Gegenstand des vorliegenden Patentes ist ein  Mittel zur Beeinflussung des Pflanzenwachstums,  insbesondere zur Bekämpfung von Unkraut, dadurch       gekennzeichnet,    dass es eine Verbindung der Formel  
EMI0003.0006     
    worin  X Sauerstoff oder Schwefel  n 0 oder 1  R,     R1,        R2,        R3    und     R4    Wasserstoff oder Kohlen  wasserstoffreste  bedeuten, und eine organische Flüssigkeit enthält.  <I>Beispiel 1</I>  5 Teile     2-Methoxy-4,6-bis-di-äthylamino-s-triazin     werden in 90 Teilen     flüssigen    Trägerstoffes, z. B.

         Äthylenchlorid    oder     Tetrachloräthan,    gelöst und mit  5 Teilen eines     nichtionogenen        Emulgators,    z. B.       Polyäthylenäther    von Fettalkoholen versetzt. Die  Lösung wird im gewünschten Verhältnis mit Wasser  vermischt und bildet eine     milchige    Emulsion.  



  <I>Beispiel 2</I>  10 Teile     2-Methylmercapto-4,6-bis-diäthylamino-          s-triazin    werden in 90 Teilen     Trichloräthylen    oder    in einer hochsiedenden Flüssigkeit, wie z. B.     Kohlen-          teeröl,    Dieselöl oder     Spindelöl,    gelöst.



  Means for influencing plant growth, in particular for combating weeds It has surprisingly been found that triazines of the formula
EMI0001.0005
    where X is oxygen or sulfur n 0 or 1 R, R1, R2, R3 and R4 are hydrogen or hydrocarbon radicals, have a growth-inhibiting and killing effect on plants even in very low concentrations. Compounds of the formula 1 defined above are, for.

   B. can be prepared by reacting cyanuric chloride with suitable alcohols or mercaptans and amines, optionally followed by reductive removal of a remaining chlorine atom, and also by reacting 2-alkyl-4,6-dichloro-s-triazines with amines. They are particularly suitable as active ingredients for weed control agents, both for the selective killing of weeds under culture plants as well as for the total killing and prevention of undesirable vegetation. Weeds here are also undesirable, e.g.

   B. understood plants previously grown or in the vicinity. The compounds defined above are also suitable as active ingredients for other inhibitory effects on plant growth, in particular defoliation, acceleration of ripening by reducing the fruit set, delaying flowering.



  As active ingredients come z. B. the following, partly known, partly new triazine derivatives in question:

      Ethylene chloride and, finally, mineral and vegetable oils or mixtures of the above substances. In particular in the case of the total killing of vegetation, in the case of premature drying out and defoliation, the effect can be achieved through the use of per se phytotoxic organic liquids, such as. B. high-boiling mineral oil fractions or chlorinated hydrocarbons are reinforced; on the other hand, the selectivity of the growth inhibition comes when using ge compared to plants indifferent carriers such. B.

    in selective weed control, may come into its own more clearly.



  The various active ingredient solutions can be added in the usual way by adding substances which improve the distribution, the adhesive strength, the rain resistance and possibly the penetration capacity, such as. B. fatty acids or resins can be adapted closer to the uses. Their biological effect can also be broadened by adding substances with bactericidal fungicides or properties that also affect plant growth.



  The present patent relates to an agent for influencing plant growth, in particular for controlling weeds, characterized in that it is a compound of the formula
EMI0003.0006
    wherein X is oxygen or sulfur n 0 or 1 R, R1, R2, R3 and R4 are hydrogen or carbon hydrogen radicals, and contains an organic liquid. <I> Example 1 </I> 5 parts of 2-methoxy-4,6-bis-di-ethylamino-s-triazine are dissolved in 90 parts of a liquid carrier, e.g. B.

         Ethylene chloride or tetrachloroethane, dissolved and treated with 5 parts of a nonionic emulsifier, e.g. B. Polyethylene ether mixed with fatty alcohols. The solution is mixed with water in the desired ratio and forms a milky emulsion.



  <I> Example 2 </I> 10 parts of 2-methylmercapto-4,6-bis-diethylamino-s-triazine in 90 parts of trichlorethylene or in a high-boiling liquid, such as. B. coal tar oil, diesel oil or spindle oil, dissolved.
