Description
Die Erfindung betrifft ein Verfahren zum Aufbringen von in wäßriger Lösung befindlichen Zusatzmitteln, wie z. B. Wirkstoffen oder Pflanzenschutzmitteln, auf umhülltes Saatgut.The invention relates to a method for applying additives in aqueous solution, such as B. active ingredients or pesticides on coated seeds.
Es ist bekannt, Saatkörner mit Zusatzmitteln, wie z. B. Düngemitteln, zu umhüllen, insbesondere einzupudern oder zu imprägnieren, oder mit einem Überzug zu versehen und in dem Überzug bestimmte Stoffe anzureichern.It is known to use seeds with additives, such as. B. fertilizers to wrap, especially to powder or to be impregnated, or to be provided with a coating and determined in the coating Enrich substances.
Es ist auch bekannt, die imprägnierten Saatkörner ίο mit einer leicht löslichen oder absprengbaren Umhüllung zu versehen und das umhüllte Saatgut zu trocknen.It is also known to use the impregnated seeds ίο to be provided with an easily soluble or detachable coating and the coated seed to be provided dry.
Auch ist es bekannt, solche Umhüllungen aus quellfähigen Bindemitteln mit Anreicherungen an Düngemitteln, Hormonen und Schädlingsbekämpfungsmitteln od. dgl. zu versehen.It is also known to enrich such coatings with swellable binders To provide fertilizers, hormones and pesticides or the like.
Bei sämtlichen bekannten Verfahren treten jedoch Verluste an den Zusatzmitteln auf, weil das Saatgut getrocknet werden muß, wobei ein großer Teil des Zusatzmittels verdunstet oder verdampft.In all known methods, however, losses of the additives occur because the seeds must be dried, with a large part of the additive evaporates or evaporates.
Aber auch beim Einpudern des Saatgutes mit Zusatzmitteln geht beim Transport ein großer Teil des Zusatzmittels infolge von Abrieb verloren.But even when powdering the seeds with additives, a large part of the is lost during transport Additive lost due to abrasion.
Hinzu kommt, daß die Gefahr gesundheitlicher Schäden für diejenigen Personen besteht, die mit der Trockenluft in Berührung kommen, die solche giftigen Zusatzmittel wie z. B. Pflanzenschutzmittel, enthält, oder die den die giftigen Pflanzenschutzmittel enthaltenden Staub einatmen.In addition, there is a risk of damage to health for those people who deal with the Come into contact with dry air which may contain such toxic additives such as B. pesticides, contains, or who inhale the dust containing the toxic pesticides.
Die Erfindung hat sich die Aufgabe gestellt, das Verfahren zum Aufbringen von in wäßriger Lösung befindlichen Zusatzmitteln, wie z. B. Wirkstoffen oder Pflanzenschutzmitteln, auf umhülltes Saatgut zu verbessern, insbesondere so auszubilden, daß die Verluste der Zusatzmittel beim Trocknen des Saatgutes und eventuelle gesundheitliche Schäden infolge der Anreicherung der Trockenluft mit giftigen Zusatzmitteln vermieden werden.The invention has the task of providing the method for applying in aqueous solution located additives, such as. B. active ingredients or pesticides to improve coated seeds, in particular to be designed in such a way that the loss of additives during the drying of the seeds and possible damage to health as a result of the enrichment of the dry air with toxic additives be avoided.
Nach der Erfindung wird das dadurch erreicht, daß das umhüllte Saatgut zunächst auf einen niedrigeren Wassergehalt getrocknet wird, als er der für die Lagerhaltung erforderlichen Luftfeuchtigkeit entsprechen würde, und daß das in einer Flüssigkeit gelöste Zusatzmittel auf dieses getrocknete Saatgut aufgebracht wird.According to the invention, this is achieved in that the coated seed is initially at a lower level Water content is dried when it corresponds to the humidity required for storage would, and that the additive dissolved in a liquid on this dried seed is applied.
Dabei kann das Aufbringen des Zusatzmittels durch Aufsprühen oder Aufschwemmen erfolgen.The additive can be applied by spraying or floating.
Zweckmäßig beträgt der Wassergehalt des umhüllten Saatgutes nach dem Trocknungsprozeß weniger als 10%, vorzugsweise 5 bis 10%.The water content of the coated seed is expediently after the drying process less than 10%, preferably 5 to 10%.
Durch dieses Verfahren sind Verluste an Zusatzmitteln vollständig vermieden, weil nach dem Aufsprühen oder Aufschwemmen des Zusatzmittels ein Trocknungsprozeß nicht mehr stattfindet. Andererseits aber besitzt das Saatgut einen handelsüblichen Wassergehalt von 12 bis 15%.Through this process there are losses of additives completely avoided because after spraying or floating the additive in The drying process no longer takes place. On the other hand, however, the seed has a commercially available one Water content from 12 to 15%.
