Description
mittel mit insektizider und fungizider Wirkung. Das Nikotin ist bekanntlich ein ausgezeichnetes Mittel zur Bekämpfung von Pflanzenschädlingen. Denn es ist äußerst wirksam gegenüber den verschiedensten Tieren, da es sowohl als Haut- als auch als Magen- und Atmungsgift angewendet werden kann.agent with insecticidal and fungicidal effects. The nicotine is well known an excellent means of combating plant pests. Because it is extreme effective against a wide variety of animals, as it is both skin and Gastric and respiratory poison can be used.
Es hat nicht an Versuchen gefehlt, das nicht immer in genügender Menge zu beschaffende Nikotin durch andere Mittel zu ersetzen.There has been no shortage of attempts, and not always in sufficient quantities to replace the nicotine to be procured with other means.
Zur Herstellung dieser neuen Stoffe sind aber meist kostspielige Apparaturen nötig, und in vielen Fällen kann man wegen der hohen Preise einheitlicher Ausgangsmaterialien nur technische Produkte verarbeiten, deren gleichmäßige Zusammensetzung nie gewährleistet werden kann.However, expensive equipment is usually required to produce these new substances necessary, and in many cases, because of the high prices, one can use uniform raw materials only process technical products whose uniform composition is never guaranteed can be.
Daher wurden Versuche unternommen, das Nikotin durch im Handel befindliche oder mit den vorhandenen Apparaturen leicht herstellbare einheitliche Verbindungen ganz oder teilweise zu ersetzen.Therefore, attempts have been made to reduce the nicotine by commercially available or uniform connections that can be easily made with the existing equipment to replace in whole or in part.
Es wurde nun gefunden, daß das i-Phenyl-2-3-dimethyl-5-pyrazolon als solches und besonders in Lösung mit Seife oder Saponin gute insektizide und fungizide Eigenschaften besitzt. So ist schon eine Lösung von 0,2 bis 0,4 Prozent dieses Pyrazolons mit o;5 bis i,o Prozent Seife imstande, grüne Läuse oder Thrips zu töten. Besonders muß hervorgehoben werden, daß auch die zartesten Pflanzen durch derartige Lösungen nicht beschädigt werden.It has now been found that the i-phenyl-2-3-dimethyl-5-pyrazolone as such and especially good insecticidal and fungicidal in solution with soap or saponin Possesses properties. A solution of 0.2 to 0.4 percent of this pyrazolone is like that with 0.5 to 1.0 percent soap capable of killing green lice or thrips. Particularly It must be emphasized that even the most delicate plants can use such solutions not be damaged.
Dieser Erfolg war überraschend und nicht vorauszusehen, da das i-Phenyl-2-3-dimethyl-5-pyrazolon eine relativ sehr ungiftige Substanz ist. Ferner wurde festgestellt, daß Mischungen von Nikotin - und dem erwähnten Pyrazolon dem Nikotin gleichwertige Effekte hervorzubringen imstande sind, was ebenfalls nicht vorauszusehen war.This success was surprising and not foreseeable, since the i-phenyl-2-3-dimethyl-5-pyrazolone is a relatively very non-toxic substance. It was also found that mixtures of nicotine - and the aforementioned pyrazolone to produce effects equivalent to nicotine are able to do what could not have been foreseen either.
Auch andere Abkömmlinge des 5-Pyrazolons sowie das i-Phenyl-2-5-dimethyl-3-pyrazolon haben gute insektizide und fungizide Eigenschaften.Other derivatives of 5-pyrazolone as well as i-phenyl-2-5-dimethyl-3-pyrazolone have good insecticidal and fungicidal properties.
Die Basen oder deren Salze können auch mit anderen insektizid oder fungizid wirkenden Stoffen, Erstickungs- oder solchen Mitteln, welche ein besseres Haften bewirken, kombiniert werden.The bases or their salts can also be used with other insecticidal or fungicidal substances, asphyxiants or such agents, which a better Affect, be combined.
Beispiel. io g i-Phenyl-2-3-dimethyl-5-pyrazolon, io g Nikotin 95prozentig, ioo g Fenchonseife mit 12 Prozent Ketongehalt werden in $8o g Wasser gelöst.Example. io g i-phenyl-2-3-dimethyl-5-pyrazolone, io g nicotine 95 percent, 100 g of fenchon soap with 12 percent ketone content are dissolved in 80 g of water.
Diese Lösung wird zur Vernichtung von Thrips mit 1¢ Teilen Wasser verdünnt und aufgespritzt, oder die Pflanzen werden hineingetaucht.This solution is used to destroy thrips with 1 ¢ parts of water diluted and sprayed on, or the plants are dipped into it.
