Description

Verfahren zur Herstellung eines kupfernitrathaltigen Unkrautvertilgungsmittels Bekanntlich wird Kupfernitrat zur Unkrautvertilgung verwendet, so z. B. in Verdünnter wäßriger Lösung zur Vernichtung von Hederieh. Es ist auch schon vorgeschlagen worden, Kupfernitrat mit inerten pulverförmigen Stoffen, wie Sand, Gips oder Talkum, innig zu vermengen und diese Mischungen mit der Hand oder mittels Sämaschinen auf die Unkrautpflanzen aufzustreuen. Die= ses Verfahren hat aber den Nachteil, daß die Streupulver wegen der hygroskopischen Eigenschaften des darin enthaltenen Kupfernitrates nach kurzer Zeit verklumpen. so daß ihre gleichmäßige Verteilung nicht mehr möglich ist.Process for the manufacture of a weedkiller containing copper nitrate It is well known that copper nitrate is used to kill weeds, e.g. B. in thinner aqueous solution for the destruction of Hederieh. It has also been suggested Copper nitrate with inert powdery substances such as sand, plaster of paris or talc, intimately to mix and apply these mixtures by hand or using a seed drill Sprinkle weed plants. This method has the disadvantage that the Scattering powder because of the hygroscopic properties of the copper nitrate it contains clump together after a short time. so that their even distribution is no longer possible is.

Es wurde nun gefunden, daß man Kupfernitrat der Formel Cu (N03), -I- 3 H, O mit wasserabstoßenden Stoffen, z. B. Ölen, imprägnieren und dann mit inerten Stoffen jedweder Art in bekannter Weise vermischen kann, wobei ein bezüglich seiner Streufähigkeit haltbares Präparat entsteht. Beispielsweise erhält man ein brauchbares Präparat zur Hederichbekämpfung, indem man 23 Gewichtsteile gepulvertes Kupfernitrat von der Formel Cü (N03)2 -f- 3 HZO mit i Gewichtsteil Maschinenöl imprägniert und alsdann mit 66 Gewichtsteilen Schlämmkreide und io Gewichtsteilen Talkum innig vermischt.It has now been found that copper nitrate of the formula Cu (N03), -I- 3 H, O can be mixed with water-repellent substances, e.g. B. oils, impregnate and then mix with inert substances of any kind in a known manner, resulting in a product that is durable with regard to its throwing power. For example, a useful preparation for combating Hederich is obtained by impregnating 23 parts by weight of powdered copper nitrate of the formula Cü (N03) 2 -f- 3 HZO with 1 part by weight of machine oil and then thoroughly mixing it with 66 parts by weight of whiting chalk and 10 parts by weight of talc.
