Als Winterspritzmittel werden heute in der Hauptsache Nitrophenole, Carbolineen als solche t der in Mischung miteinander und in Mischung mit Mineralölen benutzt. Die Wirkungsbreite der einzelnen Mittel ist im obstbaulichen Pflanzenschutz sehr verschieden. So wirkt z. B. Obstbaumcarbolineum allein nicht gegen den Apfelblütenstecher und die Gespinstmotte, gegen die Eier der San-Jose-Schildlaus und der Roten Spinne. Selbst in Kombination mit Dinitrophenolen ist es immer noch unwirksam gegen die Eier der Roten Spinne, während es die Eier der obengenannten Schädlinge abtötet. Darüber hinaus bringen derartige Mischungen mit Carbolineum oft starke Hautreizungen für den Anwender mit sich.Nitrophenols, carbolines as such, are mainly used as winter spraying agents today t used in combination with one another and in combination with mineral oils. The scope of the individual means is very different in fruit plant protection. So acts z. B. Fruit tree carbolineum but not against the apple blossom cutter and the web moth, against the eggs of the San Jose Scale Insect and the Red Spider. It always is, even in combination with dinitrophenols still ineffective against the eggs of the red spider, while it is the eggs of the above-mentioned pests kills. In addition, such mixtures with carbolineum often cause severe skin irritation for the user.

Im Gegensatz hierzu zeigen Mischungen von Mineralölen mit Nitrophenolen eine umfassende Wirkung gegen alle in Frage kommenden Schädlinge, einschließlich der Roten Spinne. Es ist jedoch noch keine Gelbölmischung bekanntgeworden, die ao mehr als 10% Nitrophenol enthält und die in der Kälte beständig ist. Die Herstellung eines hochkonzentrierten Gelböles scheiterte bislang an der geringen Löslichkeit des o-Dinitrokresols in den bisher verwandten Mineralölen. Besonders in der Kälte sind höherkonzentrierte Gelböle nicht halt-In contrast, mixtures of mineral oils with nitrophenols show a comprehensive Effective against all possible pests, including the red spider. However, it is No yellow oil mixture has yet become known which contains more than 10% nitrophenol and which is in the Resistant to cold. The production of a highly concentrated gel oil has so far failed because of the low solubility of o-dinitro cresol in the mineral oils used up to now. Especially in the Highly concentrated yellow oils cannot be held in the cold.

Man suchte diese Schwierigkeiten durch Zusätze von Lösungsvermittlern wie Tetrachlorkohlenstoff, Tetra- oder Dekahydronapfathalin, organischen Basen wie Pyridin, Nikotin oder Fettaminen zu beheben.bar. These difficulties were sought by adding solubilizers such as carbon tetrachloride, Tetra- or Dekahydronapfathalin, organic bases such as pyridine, nicotine or fatty amines remedy.

Es wurde nun gefunden, daß konzentrierte Mineralöllösungen von Nitrophenolen, die als Lösungsmittel ein Paraffinöl mit einem Siedeverhalten von 293 bis 4010 (Stockpunkt —4It has now been found that concentrated mineral oil solutions of nitro phenols as a solvent is a paraffin oil with a boiling behavior 293-401 0 (pour point -4

Ein solches Paraffinöl zeigt die Viskosität bei io° von 3,94 bis 4,8° E und unsulfonierbare Anteile in Höhe von 20 bis 25%.Such a paraffin oil has a viscosity at 10 ° from 3.94 to 4.8 ° E and unsulfonable proportions in the amount of 20 to 25%.

Ein derartiges Paraffinöl hat den Vorzug, Nitrophenole ohne Lösungsvermittler oder Zusätze von organischen Basen zu lösen. Man kann mit ihm z. B. eine iö°/oige Nitrophenollösung herstellen, die bei —15 ° nicht zur Kristallisation zu bringen ist.Such a paraffin oil has the advantage of using nitrophenols without solubilizers or additives to dissolve organic bases. You can z. B. produce a iö% Nitrophenol solution that cannot crystallize at -15 °.

ao Damit ist ein mit einem derartigen Paraffinöl hergestelltes Gelböl ohne besondere Vorsichtsmaßnahmen im Winter lagerfähig.ao This means that a yellow oil produced with such a paraffin oil does not require any special precautionary measures storable in winter.

In 79 g Paraffinöl mit einem Stockpunkt von + i° werden 15 g Dinitrokresol gelöst und 6 g oxäthyliertes Alkylphenol unter, Rühren dazugegeben. .99 Teile Wasser und 1 Teil dieser Lösung werden miteinander gemischt. Spritzt man diese Emulsion gegen Schildläuse oder Eier der Roten Spinne, so werden diese vollständig abgetötet.In 79 g of paraffin oil with a pour point of + i °, 15 g of dinitrocresol are dissolved and 6 g of oxethylated Add alkylphenol with stirring. .99 parts of water and 1 part of this solution mixed together. If you spray this emulsion against scale insects or red spider eggs, so these are completely killed.
