(Ges. v. 15. 7.51)(Ges. Of 15 7.51)

Gegenstand des Patents 892 093 sind halogenierte Nitrocarbazole zur Vertilgung von Insekten. Nach dem Patent 899434 hat sich die Verwendung von. i, 8-Dichlor-3, 6-diinitrocarbazol für die genannten Zwecke als besonders geeignet erwiesen.The subject of patent 892 093 are halogenated nitrocarbazoles for the destruction of insects. To the patent 899434 has the use of. i, 8-dichloro-3, 6-diinitrocarbazole for those mentioned Purposes proven to be particularly suitable.

Wie sich nun herausgestellt hat, kann man mit gleich guten Ergebnissen auch 1, 8-Dibrom-3, 6-d;inikrocarbazol oder seine Salze zur Bekämpfung von Insekten anwenden. Eine etwa o,25°/»ige Aufschlämmung der D ibrom verbindung vernichtet ebenso wie diejenige des 1, 8-Dichlor-3, 6-diimitrocarbazols die verschiedensten Raupen innerhalb weniger Tage. Auch trifft für die genannte Dibromverbindung in gleicher Weise: wie für diei entsprechende Dichlorverbindung der Vorteil zu, daß sie auf Warmblüter keinen schädigenden Einfluß ausübt.It has now been found that 1,8-dibromo-3, 6-d; inicrocarbazole can also be used with equally good results or use its salts to control insects. A slurry of about 0.25% the dibromo compound destroys just like that of 1,8-dichloro-3,6-diimitrocarbazole the most diverse caterpillars within a few days. Also applies to the dibromine compound mentioned in the same way: as for the corresponding dichloro compound, the advantage is that it has no harmful influence on warm-blooded animals.

Es wurden zwar schon chlorierte oder nitrierte Carbazole, wie 3-Chlorcarbazol, 3-N'itrocarbazod und 9 - Benzoyl - 3 - nitrocarbazol (vgl. »United ao States Department of Agriculture Bureau of Entomology and Plant Quarantine« vom März 1938), sowie die Salze organischer Basen, wie z. B. Carbazol mit Kiesdnuorwassarstoffsäure, zur Bekämpfung von Pflanzenschädlingen herangezogen (vgl. USA.-Patenitschrdit 2075359, besonders S. 2,There have already been chlorinated or nitrated carbazoles, such as 3-chlorocarbazole and 3-nitrocarbazod and 9 - benzoyl - 3 - nitrocarbazole (cf. »United States Department of Agriculture Bureau of Entomology and Plant Quarantine ”from March 1938), as well as the salts of organic bases, such as. B. Carbazole with Kiesdnuorwassarstoffäure to combat used by plant pests (see USA.-Patenitschrdit 2075359, especially p. 2,

Zeile 44). Derartige Carbazolderivate sind im der genannten Arbeit unter dem Gesichtswinkel untersucht worden, ob sie für die Bekämpfung von PflanzenschadMngen geeignet sind. Dabei hat man sich deir Moskitolarven als Testtiere bedient. Aus. den Versuchen ergibt sich, daß einige dieser Verbindungen, z. B. das 3-ChlorcarbazoI, eine insekticide Wirksamkeit aufweisen. Di© erfindhingsgemäßen Verbindungen; sind jedoch im ihrer insekticiden Wirkung den bekannten! Verbindungen wesentlich überlegen und übertreffen sogar das bisher für diese Zwecke fast ausschließlich verwendete Arsen.Line 44). Such carbazole derivatives are in the This work has been examined from the point of view of whether it is suitable for the fight against Plant damage are suitable. One has used the mosquito larvae as test animals. The end. the experiments show that some of these compounds, z. B. 3-chlorocarbazole, an insecticide Have effectiveness. The © according to the invention Links; however, their insecticidal effects are well-known! links substantially superior to and even surpass that which has hitherto been used almost exclusively for these purposes Arsenic.
