Description
fcrnt werden können. Dies ist besonders einfach, wenn das Schädlingsbekämpfungsmittel in Form pappearliger Platten ausgelegt wird.can be opened. This is particularly easy if the pesticide is laid out in the form of cardboard-pearl-like panels.
Pappscheiben mit einem Durchmesser von 80 bis 150 mm und einer Dicke von 5 bis 10 mm, hergestellt aus Zellstoff, enthaltend je 10 bis 20 g Aluminiumphosphid fein verteilt, werden lose in gasdicht verschlossenen Behältern aufbewahrt.Cardboard discs with a diameter of 80 to 150 mm and a thickness of 5 to 10 mm made of cellulose, each containing 10 to 20 g of finely divided aluminum phosphide, are loosely sealed in a gastight manner In containers.
Zum Gebrauch werden die Dosen geöffnet, die Scheiben auf den Boden ausgeschüttet. Unter dem Einfluß der Luftfeuchtigkeit entwickelt jede Scheibe 5 bis 10 g Phosphorwasserstoff. Zur quantitativen Entfernung der Rückstände werden die Scheiben nach Abschluß der Begasung eingesammelt.For use, the cans are opened and the discs poured out onto the floor. Under the Under the influence of air humidity, each pane develops 5 to 10 g of phosphine. For quantitative Removal of the residues, the panes are collected after the end of the fumigation.
Pappscheiben wie oben beschrieben, in deren Material jedoch außer Aluminiumphosphid (oder Magnesiumphosphid) eine ähnliche Menge Calciumcyanid in feinpulveriger Form eingearbeitet ist. Diese Scheiben entwickeln gleichzeitig Phosphorwasserstoff und Blausäure. Auch in diesem Falle können die Rückstände quantitativ durch Einsammeln der ausgegasten Scheiben entfernt werden.Cardboard disks as described above, but with the exception of aluminum phosphide (or Magnesium phosphide) a similar amount of calcium cyanide is incorporated in fine powder form. This Discs develop hydrogen phosphide and hydrocyanic acid at the same time. In this case too, the Residues can be removed quantitatively by collecting the outgassed panes.
Platten von 100 mm Länge, 50 mm Breite und etwa 10 mm Stärke aus Pappe enthalten Aluminiumphosphid oder Magnesiumphosphid, das in die Pappmasse eingearbeitet ist. Solche Platten können z. B. zur Entwesung geschütteter Waren wie Getreide oder Futtermittel verwendet werden, ebenso zur Begasung von Stapeln verpackter Waren. Man kann sie nach Abschluß der Begasung leicht entfernen, entweder durch Herausziehen, was dadurch erleichtert wird, daß die Platten miteinander durch einen Faden verbunden sein können, oder durch Absieben.Cardboard sheets 100 mm long, 50 mm wide and about 10 mm thick contain aluminum phosphide or magnesium phosphide, which is incorporated into the paperboard. Such panels can z. B. can be used for disinfestation of bulk goods such as grain or animal feed, as well as for fumigation of stacks of packaged goods. They can be easily removed after the fumigation is complete, either by pulling it out, which is facilitated by the fact that the panels are connected to one another by a thread can be connected, or by sieving.
Formkörper aus Fasermasse mit darin feinverteilier Aiurp.iniumphosphid. MagniMumphosphid oäe; Cslciumphosphid können Cz. B. mit Hilfe einer Strangpresse) zu Platten geformt oder auch zu Kügelchen gegossen werden, die bei der Begasung geschütteter Güter, z. B. in Silozellen, mit Hilfe eines automatischen Dosierungsgerätes eingebracht werden.Shaped body made of fiber mass with finely distributed therein Aiurp.inium phosphide. MagniMumphosphid oäe; Cslciumphosphid can Cz. B. with the help of a Extrusion press) formed into plates or into spheres be poured, which in the fumigation of bulk goods such. B. in silo cells, with the help of a automatic dosing device are introduced.
ίο Ihre Entfernung erfolgt quantitativ durch die der Vermahlung vorangehende Getreidereinigung. Solche Formkörper können auch zur Schädlingsbekämpfung im Boden (z. B. Wühlmausbekämpfung) vorteilhaft verwendet werden.ίο Their removal is done quantitatively by that of the Grain cleaning prior to grinding. Such moldings can also be used for pest control can be used advantageously in the soil (e.g. vole control).
