Description
Es ist bekannt, dass chemische Verbindungen, die als pflanzliche Wuchsstoffe verwendbar sind, wie 2,4-Dichlor-phenoxyessigsäure, 4-Chlorphenoxyessigsäure, Naphthoxyessigsäure und andere nicht nur das Pflanzenwachstum fördern, sondern, in grösseren Konzentrationen angewandt, das Wachstum verzögern und auch die Keimung von Kartoffeln und Hackfrüchten hemmen. Dabei ist aber Voraussetzung, dass die Augen der Kartoffeln von den Säuren berührt werden, was kaum durch trockenes Bestäuben erreicht werden kann. Eine nasse Behandlung verbietet sich aber, da die Kartoffeln nicht feucht werden dürfen.It is known that chemical compounds that can be used as plant growth substances, such as 2,4-dichloro-phenoxyacetic acid, 4-chlorophenoxyacetic acid, naphthoxyacetic acid and others not only promote plant growth, but also, when used in larger concentrations, delay growth and also Inhibit the germination of potatoes and root crops. A prerequisite for this is that the eyes of the potatoes are touched by the acids, which can hardly be achieved by dry dusting. A wet treatment is forbidden, however, as the potatoes must not get wet.
Es wurde nun gefunden, dass diese Schwierigkeit behoben und eine sehr viel stärkere und gleichmässigere keimhemmende Wirkung bei Kartoffel und Hackfrüchten erzielt werden kann, wenn man an Stelle der freien Säuren Ester dieser phytohormonähnlichen Stoffe der allgemeinen FormelIt has now been found that this problem can be remedied and a much stronger and more uniform germ-inhibiting effect on potatoes and root crops can be achieved if, instead of the free acids, esters of these phytohormone-like substances of the general formula are used
R(exp)1O - (CH(sub)2)(sub)n - COOR(exp)2R (exp) 1O - (CH (sub) 2) (sub) n - COOR (exp) 2
verwendet, in der R(exp)1 ein substituiertes oder unsubstituiertes aromatisches Radikal, R(exp)2 ein aliphatisches, alicyclisches oder aromatisches Radikal und n = wenigstens 1 bedeutet.is used in which R (exp) 1 is a substituted or unsubstituted aromatic radical, R (exp) 2 is an aliphatic, alicyclic or aromatic radical and n = at least 1.
Als Ester dieser Art seien z.B. angeführt 2,4-Dichlor-phenoxyessigsäuremethylester, -äthylester, -isopropylester u.a., 4-Chlorphenoxyessigsäure-methylester, -äthylester u.a.Examples of esters of this type include methyl 2,4-dichlorophenoxyacetate, ethyl ester, isopropyl ester, and others, methyl 4-chlorophenoxyacetate, ethyl ester, and others.
Von veresterten Säuren mit keimungsverhindernder Wirkung ist bisher der (Alpha)-Naphthylessigsäureester bekannt, dessen Wirkung jedoch von der der Säureester oben beanspruchter Konstitution bei weiten übertroffen wird.The (alpha) -naphthylacetic acid ester is known of esterified acids with a germ-preventing effect, but its effect is by far exceeded by the constitution claimed above.
Die Verwendung der wirksamen Ester geschieht in üblicher Weise, indem sie allein oder zweckmässiger mit einem Füllstoff, wieThe use of the active esters is done in the usual way by using them alone or more conveniently with a filler, such as
Kaolin, Schiefermehl u.a., vermischt und die trockene Mischung über das zu behandelnde Gut ausgestreut wird. Als Fäulnisschutzmittel können ausserdem Zusätze von Desinfektionsmitteln, z.B. Formaldehyd, beigemischt werden. Ferner können auch andere Zusätze, z.B. insektizide Stoffe, Farbstoffe, als Abschreckmittel usw. zugefügt werden.Kaolin, slate flour, etc., are mixed and the dry mixture is sprinkled over the material to be treated. Additives of disinfectants, e.g. formaldehyde, can also be added to protect against rot. Other additives such as insecticides, dyes, deterrents, etc. can also be added.
Beispiele:Examples:
1. 20 g 2,4-Dichlorphenoxyessigsäure-methylester werden mit 80 g Kaolin zu einem trockenen Pulver zusammengemischt.1. 20 g of methyl 2,4-dichlorophenoxyacetate are mixed with 80 g of kaolin to form a dry powder.
5-10 g des Kaolins können auch durch eine braune Mineralfarbe ersetzt werden.5-10 g of the kaolin can also be replaced with a brown mineral color.
2. 10 g 4-Chlorphenoxyessigsäure-methylester werden mit 30 g Kieselgur, 55 g Kaolin und 5 g Dichlordiphenyltrichloräthan zu einem trockenen Pulver zusammengemischt.2. 10 g of methyl 4-chlorophenoxyacetate are mixed together with 30 g of kieselguhr, 55 g of kaolin and 5 g of dichlorodiphenyltrichloroethane to form a dry powder.
3. 5 g 2,4-Dichlorphenoxyessigsäure-iso-amylester werden mit 5 g Paraformaldehyd und 90 g Kaolin zu einem trockenen Pulver zusammengemischt.3. 5 g of iso-amyl 2,4-dichlorophenoxyacetate are mixed together with 5 g of paraformaldehyde and 90 g of kaolin to form a dry powder.
