Description
Winterspritzmittel zur Bekämpfung von Schädlingen an unbelaubten Pflanzen
Es hat sich indessen herausgestellt, daß die Emulsionen finit Dichlordiphenyltrichloräthan einige lnsektenarten, besonders Blattläuse, zuwenig angreifen, weil .diese Arten als Larve oder Imago verhältnismäßig unempfindlich sind gegen DichlorcIipiieny ltrichloräthan und als Eier durch diesen Stoff gar nicht geschädigt werden. Zur Zeit der Bespritzunh im Winter befinden sie sich im Eistadium, und wenn sie später ausschlüpfen, ist die residuelle Aktivität des Dichlordiphenyltrichloräthan ungenügend, um einen großen Prozentsatz abzutöten.It has been found, however, that the emulsions are finitely dichlorodiphenyltrichloroethane attack some insect species, especially aphids, too little because these species as larva or imago are relatively insensitive to dichlorocipiieny ltrichloroethane and as eggs are not damaged at all by this substance. At the time of spraying in winter they are in the egg stage, and when they hatch later, it is the residual activity of the dichlorodiphenyltrichloroethane is insufficient to produce a large Kill percentage.
Auch die Emulsionen, welche Dinitro-3, 5-ortktokresol enthalten, ergeben nicht ganz befriedigende Resultate, indem die Nachwirkung zu gering ist, um auch Schädlingen, die zur Zeit der Bespritzung tief versteckt saßen oder die sich erst nach der Bespritzung auf den Bäumen und Pflanzen niedergelassen haben, noch Schaden zuzufügen. Zum Beispiel werden Frostspanner (Cheimotobia brumata L), Apfelblütensteeher (Anthonomus pomorum L), Springwurmwickler (Tortrix Spec.) und Minierraupen (Coleophora Spec.), welche in Obstgärten äußerst schädlich sein können, ungenügend bekämpft.The emulsions which contain dinitro-3, 5-ortktocresol also result not entirely satisfactory results in that the aftereffect is too small, around also pests that were deeply hidden at the time of spraying or that were themselves only settled on the trees and plants after the spraying, yet To inflict harm. For example, frost wedges (Cheimotobia brumata L), apple blossom tea makers (Anthonomus pomorum L), leafworm moth (Tortrix spec.) And leaf miners (Coleophora Spec.), Which can be extremely harmful in orchards, are inadequately controlled.
Nian war allgemein der Ansicht, daß für eine wirksame Bekämpfung aller wichtigen Schädlinge mehrere Bespritzungen erforderlich seien, damit die Schädlinge je in einem empfindlichen Entwicklungsstadium angegriffen würden.Nian was generally of the opinion that for effective combat against all important pests several sprayings are required to keep the pests would ever be attacked at a sensitive stage of development.
Es wurde nun gefunden, daß eine überraschend günstige Wirkung erzielt wird, wenn als Winter-Spritzmittel eine öl-in-Wasser-Emulsion benutzt wird, welche ein Nitrophenol und bzw. oder ein Nitrokresol und bzw. oder ein Homologes dieser Nitroverbindungen (wie z. B. Dinitro-3, 5-orthokresol oder Dinitro-2, 4-orthocyclohexylphenol) in der Olphase gelöst enthält und welche außerdem Dichlordiphenyltrichloräthan enthält. In denmeisten Fällen genügt eine einzige Bespritzung. Die Wirkung ist weit größer, als auf Grund der bekannten Eigenschäften der Komponenten vorherzusehen war. Merkwürdigerweise ist die residuelle Wirkung so groß. daß auch später gebildete Knospen, Blumen, Schößlinge und Blätter noch geschützt werden nach einer Bespritzung der kahlen Pflanze in Winterruhe.It has now been found that a surprisingly beneficial effect is achieved if an oil-in-water emulsion is used as a winter spray, which a nitrophenol and / or a nitrocresol and / or a homologue of these Nitro compounds (such as dinitro-3, 5-orthocresol or dinitro-2, 4-orthocyclohexylphenol) contains dissolved in the oil phase and which also contains dichlorodiphenyltrichloroethane. In most cases a single spray is sufficient. The effect is far greater than could be foreseen based on the known properties of the components. Strangely enough the residual effect is so great. that also later formed buds, flowers, saplings and leaves are still protected after the bare plant has been sprayed in hibernation.
Möglicherweise beruht die günstige Wirkung auf der Bildung einer dünnen Ölschicht, welche das Dichlordiphenyltrichloräthan gegen die Einwirkung %-on Regen und Wind schützt. Andererseits dürfte es einen großen Einfluß haben, daß, wie festgestellt wurde. einiges Dichlordiphenyltrichloräthan mit dem 01 in die Pflanzen eindringt.The beneficial effect may be based on the formation of a thin layer of oil, which protects the dichlorodiphenyltrichloroethane against the effects of rain and wind. On the other hand, it is likely to have a great impact that, as has been stated. some dichlorodiphenyltrichloroethane with which the 01 penetrates the plants.
Nach der Erfindung können die Winterspritzmittel gemäß der Erfindung derart 'hergestellt werden, daß Mineralöllösungen der obengenannten Nitroverbindungen zusammen mit Dichlordiphenyltrichloräthan unter Zugabe eines geeigneten Emulgators in Wasser emulgiert werden.According to the invention, the winter spray according to the invention such 'are produced that mineral oil solutions of the above-mentioned nitro compounds together with dichlorodiphenyltrichloroethane with the addition of a suitable emulsifier be emulsified in water.
Beispiel 75 1 Spindelölraffinat venezuelischer Herkunft, welches 2 Gewichtsprozent Dinitro-3, 5-orthokresol und 2 Gewichtsprozent Dichlordiphenyltrichloräthan enthielt, wurde mit Hilfe von Casein als Emulgator in 25 1 Wasser dispergiert.Example 75 1 spindle oil refined product of Venezuelan origin, which is 2 Percent by weight of dinitro-3, 5-orthocresol and 2 percent by weight of dichlorodiphenyltrichloroethane was dispersed in 25 l of water with the aid of casein as an emulsifier.
Die konzentrierte Emulsion, «-elche in dieser Weise erhalten war, wurde mit der 16fachen Menge Leitungswasser verdünnt, und diese verdünnte Emulsion wurde angewandt zur Bespritzung von Apfelbäumen, welche u. a. mit Blattlauseiern, Rotspinneneiern und Frostspannereiern besetzt waren, während auch Springwurmwicklerraupen, eingesponnen in dürre Blätter, vorkamen und nach der Erfahrung früherer Jahre ein schwerer Befall durch Apfelblütenstecher zu befürchten war.The concentrated emulsion, which was obtained in this way, was diluted with 16 times the amount of tap water, and this diluted emulsion was used for spraying apple trees, which i.a. with aphid eggs, Red spider eggs and frost tension eggs were occupied, while gerbilworm caterpillars, spun into dry leaves, occurred and based on the experience of previous years severe infestation by apple blossom prick was to be feared.
Es stellte sich heraus, daß alle genannten Schädlinge durch die Bespritzung erfolgreich bekämpft wurden. Das Resultat war erheblich besser als nach einer Bespritzung mit Obstbaumkarbolineum, mit einer wäßrigen Suspension von Dinitro-3, 5-orthokresol oder von Dichlordiphenyltrichloräthan und mit Spindelölemulsionen, welche entweder nur Dinitro-3, 5-orthokresol oder nur Dichlordiphenyltrichlormethylmethan in vergleichbaren Mengen gelöst enthielten.It turned out that all of the named pests were caused by the spraying were successfully fought. The result was considerably better than after a spraying with fruit tree carbolineum, with an aqueous suspension of dinitro-3, 5-orthocresol or from dichlorodiphenyltrichloroethane and with spindle oil emulsions, which either only dinitro-3, 5-orthocresol or only dichlorodiphenyltrichloromethylmethane in comparable Amounts contained dissolved.
