  Verfahren zur Bekämpfung von     Nematoden.       Über die im Erdboden     lebenden        Nema-          toden    und ihre     Behämpfung    liegt ein um  fangreiches     Schrifttum    vor. Eine kurz     zu-          sammenfaesende    Übersicht gibt zum     Beispiel     Forst     Fey    in, seinem     "Wörterbuch    der Un  geziefer-,     Schädlings-    und     Pflanzenkrank-          heits-Bekämpfung",    2. Auflage 1989, Seite  157-158.

   Befallen werden zum Beispiel  Kartoffeln, Rüben,     Getreidle,    Klee, Erbsen,       Bohnen,    Gurken, Tomaten,     Zwiebeln,    Erd  beeren, Tulpen, Chrysanthemen, Narzissen       und    andere Gewächse. Der Befall wirkt sich  in einem Dahinsiechen. der Pflanzen, das zu  ihrem Absterben führen kann,     bezw.    in ver  minderten Ernteerträgen aus.

   Es besteht  daher     das    Bedürfnis nach einem guten und  unschädlichen     Nematodenbekämpfungsmittel.       Es wurde nun gefunden, dass Verbindun  gen, die den Rest der allgemeinen Formel  
EMI0001.0022     
    enthalten, in welcher R" einen     organischen     Rest bedeutet, sich in     hervorragendem    Masse  zur Bekämpfung der     Nematoden    eignen.  



       Vorzugsweise        verwendet    man     Verbindun-          gen    der     allgemeinen    Formel  
EMI0001.0031     
    in der R, R' und     R"        organische    Reste be  deuten, die     Alkyl-,        Aryl    oder     Amalkylreste     sein     können.    Man kann aber auch Verbin  dungen der     allgemeinen        Formell,     
EMI0001.0040     
    verwenden, in welcher R' und R" wiederum       organisclhe    Reste bedeuten.  



  Verbindungen, die bei dem. erfindungs  gemässen Verfahren zur Verwendung kom  men können,     .sind-leispielsweise:    Dimethyl--           dithiocarbaminsäuremeth@ylester,        Dimethyl        -          dithiocarbamin!säureallyleSter,        Diäthylditb:io-          carbamins@äuremethyllester,        Dimethyldithio-          carbamimsä;

  urebenzylester,        [email protected]          thioca.rbamin6äurearalkylester.    Sie können  in- Lösung, Emulsion oder in festem Zu  stand verwendet und mit     Verdünnungs-,     Streck- oder Düngemitteln auf :die Gebrauchs  konzentration gebracht werden.  



  Die Mittel können vor, während oder  nach der     Anssaat        bezw.    dem     Einsetzen    der       Pflanzen    in den Boden gebracht werden,  .loch lassen sich in vielen Fällen mit Vorteil  auch die Samen,     Knohlen    oder Pflanzen  selbst mit ihnen behandeln. Zwar sind einige  Körper dieser     Klaese    zur Bekämpfung von       gewissen    Insekten und Pilzen bekannt, doch  lässt sich :aus, dieser     spezifischen        Wirkung     nicht auf ihre überraschenden     nematoziden          Eigenschaften    schliessen.  



  Auf einem von     Nematoden    befallenen,       ordnungsgemäss        vorbehandelten        Ackerstück          wurden.    100     g/m2    einer Mischung aus 10  Teilen     Dimethyl,dithiocarba.minsäure-methyl-          ester,    88 Teilen Braunkohlenstaub und  2 Teilen Mineralöl ausgestreut und einge  <B>eggt.</B> Kurz darauf wurden die Kartoffeln  ausgelegt.

   Während der Sommermonate fiel  der gesunde und kräftige Wuchs der Pflan  zen auf     dem.    behandelten     Stück    gegenüber  einem daneben     liegenden    unbehandelten       Ackerstück    auf. Der Erfolg der Behandlung  zeigte sich bei der Ernte darin,     da.ss    das un  behandelte     Stück    50     dz/ha,        das    behandelte  aber 204     diz/ha    Kartoffeln ergab.  



  Nach der     Behandlung    des mit     Nema.toden     verseuchten Bodens eines,     Gurkengewächs-          h.auses    mit 50     g]m@    einer     Miseh,ung    mit einem       Gehalt    von<B>50%</B>     Di@methyldithiocarbami@n-          säurümethybester    konnten völlig     älehenfreie     Pflanzen herangezogen werden, was sich in  einem guten     Ernteergebnis        auswirkte.     



  Man hat bereits     dithioca.rbaminsaure    Salze  als     Bodenbehandlungsmittel    zur Immunisie  rung von     Pflanzen    gegen Rost benutzt.     Ini          Gegensatz    zu     den;

          Estern    besitzen sie aber  nur eine sehr     geringe    Wirkung bei der     Ne-          matodenbekämpfung.    Derivate der Dithio-         carbaminsäure    und besonders Ester sind  weiter     zur        desinfizierenden,        fungiziden,    bak  teriziden,     insekfiziden    und     sterilisierenden          Behandlung    in Vorschlag gebracht worden.

         Hieraus    konnte aber kein Schluss auf     nema-          tozide    Wirkungen der     Dithiocarbaminsäure-          ester    gezogen  -erden, da man weder mit den       zahlreichen    andern     Bakteriziden    noch mit  den üblichen Insektiziden     Nemato-den    wirk  sam bekämpfen. kann.

   Das bisher einzig       wirk'.lich        brauchbare    Mittel, der     Sehwefe:l-          kohlenstoff,    hat infolge seiner Brennbarkeit,  Explosivität und Giftigkeit schon lange  einen Ersatz als     wünschenswert    erscheinen.  lassen. Im übrigen kann man aus der     Wir-          kuug    einer Substanz gegen Pilze oder In  sekten, wie zum Beispiel Blattläuse, keines  wegs auf ihre     nematoziden    Wirkungen  schliessen.



  Methods of combating nematodes. There is extensive literature on the nematodes living in the ground and their control. A brief overview is given, for example, by Forst Fey in his "Dictionary of combating vermin, pests and plant diseases", 2nd edition 1989, pages 157-158.

   Potatoes, beets, cereals, clover, peas, beans, cucumbers, tomatoes, onions, strawberries, tulips, chrysanthemums, daffodils and other plants are infected. The infestation results in a wasting away. of plants that can lead to their death, respectively. in reduced crop yields.

   There is therefore a need for a good and harmless nematode control agent. It has now been found that compounds which correspond to the remainder of the general formula
EMI0001.0022
    contain, in which R "means an organic radical, are outstandingly suitable for combating nematodes.



       Compounds of the general formula are preferably used
EMI0001.0031
    in which R, R 'and R "denote organic radicals which can be alkyl, aryl or amalkyl radicals. However, compounds of the general formula
EMI0001.0040
    use, in which R 'and R "in turn mean organic radicals.



  Connections that are used in the. Processes according to the invention can be used, for example: dimethyl-dithiocarbamic acid methyl ester, dimethyl-dithiocarbamic acid all-ester, diethylditb: iocarbamic acid methyl ester, dimethyldithio-carbamic acid;

  urebenzylester, [email protected]äurearalkylester. They can be used in solution, emulsion or in solid state and brought up to the usage concentration with diluents, extenders or fertilizers.



  The means can bezw before, during or after the sowing. When the plants are set into the ground, they can also be used to treat the seeds, knots or plants themselves with advantage in many cases. Although some of the bodies of this class are known to combat certain insects and fungi, one cannot infer their surprising nematocidal properties from this specific effect.



  On a properly pretreated field that was infested with nematodes. 100 g / m2 of a mixture of 10 parts of dimethyl, dithiocarba.mic acid methyl ester, 88 parts of pulverized lignite and 2 parts of mineral oil were spread over and harrowed. Shortly afterwards, the potatoes were laid out.

   During the summer months the healthy and vigorous growth of the plants fell on the. treated piece compared to an untreated piece of land lying next to it. The success of the treatment was shown at harvest in that the untreated piece yielded 50 dz / ha, but the treated piece yielded 204 diz / ha of potatoes.



  After treating the soil of a cucumber greenhouse contaminated with Nema.toden with 50 g] m @ a mixture with a content of <B> 50% </B> Di @ methyldithiocarbami @ n-acid methyl esters were completely free Plants are used, which resulted in a good harvest result.



  One has already used dithioca.rbamic acid salts as soil treatment agents for the immunization of plants against rust. Ini contrast to the;

          However, esters have only a very slight effect on nematode control. Derivatives of dithiocarbamic acid and especially esters have been proposed for disinfectant, fungicidal, bactericidal, insecticidal and sterilizing treatment.

         From this, however, no conclusion could be drawn about the nematocidal effects of the dithiocarbamic acid esters, since nematodes cannot be effectively combated with either the numerous other bactericides or the usual insecticides. can.

   The only really useful means up to now, the sulfuric oil, has long appeared to be a desirable substitute because of its flammability, explosiveness and toxicity. to let. In addition, one cannot in any way infer its nematocidal effects from the action of a substance against fungi or insects, such as aphids.
