Mittel zur Bekämpfung von Vorratsschädlingen.
Es wurde die bemerkenswerte Beobachtung gemacht, dass die Homologen des Pyridins vorzügliche Mittel zur Vertilgung von Vorratsschädlingen, insbesondere des Kornkäfers, sind. Sie übertreffen in letzterer Hinsicht bei weitem den für die Vertilgung von Kornkäfern als Spezifikum empfohlenen Schwefelkohlenstoff und sogar die Blausäure und ihre Derivate, wie z. B. den Cyankohlensäureester, das Cyclon. Diese Wirkung ist in hohem Grade überraschend, da der Kornkäfer äusserst widerstandsfähig ist.
In der Münchener Medizinischen Woehensehrift 1920, S. 780, ist unter Versuch 4, Absatz 2, der Satz aufgenommen :"Den Versuch überlebten wiederum die Kornkäfer, diese Form hat sich auch gegen alle bis jetzt geprüften Giftstoffe als ausserordentlich resistent erwiesen."
EMI1.1
einer Mischung der Pyridin-Homologen vom Siedepunkt 150 -170 zur Verdampfung gebracht. Schon nach fünf Minuten waren sämtliche Kornkäfer ohne Bewegung. Nach halbstündiger Einwirkung waren sämtliche Tiere sicher abgetötet. Wendet man Schwefelkohlenstoff an, so ist selbst bei zehnfaeher Konzentration keinerlei Wirkung festzustellen.
Blausäure unter den gleichen Bedingungen bei der gleichen Volumenkonzentration ist ebenfalls wirkungslos und selbst bei der fünffachen Konzentration erholten sich alle Tiere nach 1-2 Tagen wieder.
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

Means for the control of stored product pests.
The remarkable observation has been made that the homologues of pyridine are excellent agents for exterminating storage pests, especially the grain beetle. In the latter respect, they far exceed the carbon disulfide recommended as a specific for the extermination of grain beetles and even hydrogen cyanide and its derivatives, such as. B. the cyanocarbonic acid ester, the cyclone. This effect is highly surprising since the grain beetle is extremely resistant.
In the Munich Medical Woehensehrift 1920, p. 780, under experiment 4, paragraph 2, the sentence is included: "The experiment again survived the grain beetles, this form has also proven to be extremely resistant to all toxins tested up to now."
EMI1.1
a mixture of the pyridine homologues from boiling point 150-170 to evaporate. After only five minutes, all of the grain beetles were motionless. After half an hour of exposure, all animals were safely killed. If carbon disulfide is used, no effect whatsoever can be observed even at ten times the concentration.
Hydrocyanic acid under the same conditions at the same volume concentration is also ineffective and even at the fivefold concentration all animals recovered after 1-2 days.
** WARNING ** End of DESC field may overlap beginning of CLMS **.
