Description

Schutzmittel isc,thiocyanate sind bisher im Pflanzenschutz und in der Bakteriologie nur in geringem Umfang zur @1nw-endung ge'kotnmen. 1lan hat Allylsenföl und I'hen@-lsenf<il z. !3'. zur Bodendesinfektion gegen Kartofelälchen empfohlen. auch als Insektic.iJe und Baktericide wurden einige dieser Verbindungen geprüft. Meistens haben sie jedoch all-, gemeine ohetnische, physikalische oder physiologische Eigetrschaften, die einer Verwendung entgegenstehen.Protective agents isc, thiocyanates have been used in crop protection and in the bacteriology only to a small extent used the @ 1nw -endung. 1lan has allyl mustard oil and I'hen @ -lsenf <il z. ! 3 '. Recommended for soil disinfection against potato flakes. some of these compounds were also tested as Insektic.iJe and Baktericide. Most of the time, however, they have general, common aesthetic, physical, or physiological Attributes that stand in the way of use.

Indessen wurden bei aliphatisclien Di,isofhiocyanaten der allgemeinen Formel SC, N -X-\ CS so günstige Eigenschaften, gepaart mit überraschend starker fungicider und auch insekticider sowie baktericider Wirkung, festgestellt, @daß ein breites Anwendungsg ebiet hierfür erschlossen ist.In the case of aliphatic groups, however, di, isophiocyanates became the general Formula SC, N -X- \ CS such favorable properties, paired with surprisingly strong ones fungicidal and also insecticidal and bactericidal effects, found @ that a broad area of application has been developed for this.

In der obigen Formel ist X ein beliebiger, Cregebetienfalls ungesättigter Kohlenwasserstoffrest von zwei oder mehr Kohlenstoffatomen, der außerdem noch durch Heteroatome oder -gruppen, wie Sauerstoff, Schwefel, tertiäre Aminogruppen, Otiecksilber, Arsen, unterbrochen seht kann.In the above formula, X is any arbitrary, if more unsaturated, Cregebetien Hydrocarbon radical of two or more carbon atoms, which is also still through Heteroatoms or groups, such as oxygen, sulfur, tertiary amino groups, silver, Arsenic, can see interrupted.

Diese Verbindungen haben vor den eingangs (x nannten den Vorteil höherer Wirksamkeit, was wohi zum Teil darauf .beruht, dab sie mehr als eine Isoth,iocyanatgruppe im Molekül enthalten, den Vorzug geringer Flüchtigkeit wegen des hohen Siedepunktes und den Vorteil des kaum wahrnehmbaren Geruchs wegen des niedrigen Dampfdruckes. Als besonders wirksam haben sich z. B. das Butandiisothiocyanat-i, 4 und das Diisoth.iocyanat des y, y-Diaminodipropyläthers erwiesen.These compounds have the advantage of being more effective than the ones mentioned at the beginning (x , which is partly due to the fact that they contain more than one isocyanate group in the molecule, the advantage of low volatility because of the high boiling point and the advantage of the barely perceptible odor because of The low vapor pressure, for example, butanediisothiocyanate-1,4 and the diisothiocyanate of γ, γ-diaminodipropyl ether have proven to be particularly effective.

Als Saatgutbeizmittel angewandt ergaben die Diisothiocyanate u. a. eine starke funigici,de Wirkung gegenüber Helminthasporium, Ustilago hordei, Tilletia tritici und Ustilago avenae; gleichzeitig besitzt das so gebeizte Getreide insekticide Eigenschaften.When used as a seed dressing agent, the diisothiocyanates gave i.a. a strong funigici, de effect on Helminthasporium, Ustilago hordei, Tilletia tritici and Ustilago avenae; At the same time, the grain so pickled has insecticides Properties.

Gegenüber Schimmelpilzen, wie Aspergil,lus, Penicillium, Cla.dasporium, Fusarium, Coniophora, Fusicladium, zeigen die Diisothiocyanate zum Teil eine totale Keim- und Wadhstumsihe.mmung bei Konzentrationen von etwa 1 : 300 ooo. Bact. coli wird noch bei 1 :50 000 total gehemmt. Sie eignen sich dadurch auch in besonderem Maße für die Zwecke der technischen Desinfektion. Wanzen, Kornkäfer und andere Insekten werden durch die aldphatischen Di@isothiocyanate abgetötet.Compared to molds, such as Aspergil, Ius, Penicillium, Cla .asporium, Fusarium, Coniophora, Fusicladium, the diisothiocyanates show in some cases a total germination and growth series at concentrations of about 1: 300,000. Bact. coli is still totally inhibited at 1: 50,000. This makes them particularly suitable for technical disinfection purposes. Bedbugs, grain beetles and other insects are killed by the aliphatic di @ isothiocyanates.

Die gleichzeitige fungicide, inse'kticide und ha'ktericideWirkung der aliphatischen Diis@othiocyanate ist für den Pflanzenschutz und die technische Konservierung von besonderem Vorteil.The simultaneous fungicidal, insecticidal and ha'ktericidal action the aliphatic Diis @ othiocyanate is for the plant protection and the technical Conservation of particular advantage.
