Description

Pflanzenschutzmittel Es ist bereits bekannt, aromatische Isothiocyanate (Senföle) als _Schäddingsbekämpfungsmittel zu verwenden. Es ist weiterhin bereits bekannt, zur Bekämpfung von Insektenaromatische Verbindungen zu benutzen, die mehr als einen Rhodanrest bzw. die neben dem Rhoäan.-rest - Schwefeläthergruppen enthalten; bei diesen Verbindungen befindet sich der Rhodanrest jedoch an einer aliphatischen Seitenkette, wie z. B. im Falle des Methoxyxylyldirhodanids.Pesticides It is already known aromatic isothiocyanates (Mustard oils) to be used as a pest control agent. It still is already known to use aromatic compounds to combat insects, the more as a Rhodan residue or which, in addition to the Rhoäan.-residue, contain sulfur ether groups; in these compounds, however, the rhodan residue is on an aliphatic one Side chain, such as B. in the case of Methoxyxylyldirhodanids.

Es wurde nun gefunden, daß man aromatische Verbindungen, die neben mindestens einer Nitrogruppe eine Rhodangnippe im Benzol-ring selbst enthalten, mit besonderem Vorteil als Pflanzenachutzmittel verwenden kann. Weiterhin können. auch noch andere Kernsubstituenten vorhanden sein, wie Hydroxyl, Amino, Halogen, Alkyl, Aryl, Aralkyl oder .auch eine weitere Rhodangruppe. Verbindungen der genannten Art sind beispielsweise 2 # 4-Dinitro-i-Rhodanbenzol, q. # 6-Dinitro-i # 3-Dirhodanbenzol, 2 . q. # 6-Trinitrorhodanbenzol, 4-Chlor-2-Nitro-i-Rhodanbenzod, 2-Nitrö-4-Rhodananilin.It has now been found that aromatic compounds, in addition to at least one nitro group contains a Rhodangnippe in the benzene ring itself, can be used with particular advantage as a plant maintenance agent. Furthermore you can. other core substituents may also be present, such as hydroxyl, amino, halogen, Alkyl, aryl, aralkyl or .also another rhodan group. Connections of the named Type are for example 2 # 4-Dinitro-i-Rhodanbenzol, q. # 6-Dinitro-i # 3-Dirhodanbenzene, 2. q. # 6-Trinitrorhodanbenzol, 4-Chloro-2-Nitro-i-Rhodanbenzod, 2-Nitro-4-Rhodananiline.

Es kann zweckmäßig sein, den Pflanzenschutzmitteln inerte Stoffe, gegebenenfalls auch Netz-, Haft- oder Dispergierungsmittel, zuzusetzen.It may be useful to add inert substances to the pesticides, if appropriate, wetting agents, adhesives or dispersants can also be added.

Gegenüber bekannten aromatischen Verbindungen, die die Rhodangruppe als Kernsubstituenten enthalten, zeichnen sich die Nitrorhodanverbindungen dadurch aus, daß sie keine Verbrennungen an Pflanzenteilen hervorrufen. Beispilele i. Zur Bekämpfung des Schorfs (Fusicladium) eignet sich ein Präparat, das. aus 1o% 2 # 4-Dinitrorhodanbenzol, So 0.'o Schlämmkreide und io% Zellpech besteht. Eine daraus. hergestellte i %ige Spritzbrühe vermag die damit behandelten Obstbäume vor Schorfhefall zu schützen.Compared to known aromatic compounds that form the rhodan group contain as core substituents, the nitrorhodane compounds are characterized by this ensure that they do not cause burns to parts of plants. Examples i. To the Combat scab (Fusicladium) is a preparation that. From 1o% 2 # 4-Dinitrorhodanbenzol, So 0.'o whiting chalk and 10% cell pitch. One of them. The fruit trees treated with it are capable of producing i% strength spray liquor to protect against scab fall.

z. Mit einem Präparat, das aus i 5 % Rhodandi,nitrobenzol, 5% Kupferoxyrhlorid, 70% Schlämmkreide und i o °/o Zellpech besteht, kann man die Peronospora der Reben bekämpfen, wenn man dasselbe in i olo iger Brühe verspritzt. Dieser Spritzlösung können zur gleichzeitigen Vernichtung der im Weinbau auftretenden tierischen Schädlinge (Heu- und Sauerwurm usw.) die üblichen Insektizide zugesetzt werden.z. With a preparation consisting of i 5% rhodandi, nitrobenzene, 5% copper oxychloride, 70% whitewashed chalk and 10% cell pitch, one can detect the downy mildew of the vines if you sprinkle the same thing in olive broth. This spray solution can simultaneously destroy the animal pests occurring in viticulture (Hayworm and sourworm etc.) the usual insecticides are added.

3. Zur Bekämpfung der Braun$eckenkrankheit von Tomaten (C1adosporium fluvum) eignet sich ein Stäubemittel, das. aus. 7,50/0 Rhodandinitrobenzol und 9a,5% Talkum besteht.3. To combat brown corner disease of tomatoes (C1adosporium fluvum) is a dust that. 7.50 / 0 rhodandinitrobenzene and 9a, 5% Talc is composed.

4. Die aromatischen Nitrorhodanverbndungen eignen sich zur Unterdrückung des Grauschimmels. (Botrytis cinerea). Mit einem Präparat, .das aus i 5 % Rhodandinitrobenzol, im übrigen Inertmäterial, wie Kreide, Kaolin, Netz-, Haft- und Dispergiermittel, besteht, kann man mit gutem Erfolg die Stielfäule der Trauben bekämpfen, wenn man eine i/,- bis i %ige Brühe der obengenannten Zubereitung für sich oder in Mischung mit den üblichen kupferhaltigen Spritzmitteln des Weinbaues verwendet.4. The aromatic nitrorhodane compounds are suitable for suppression of gray mold. (Botrytis cinerea). With a preparation that consists of 5% rhodandinitrobenzene, otherwise inert materials, such as chalk, kaolin, wetting agents, adhesives and dispersants, you can fight stem rot of the grapes with good results if you an i /, - to i% strength broth of the above preparation alone or as a mixture used with the usual copper-containing sprays in viticulture.
