Description

Verfahren zur Herstellung eines Saatguttrockenbeizmittels Die Anwendung von Quecksilberoxyd und Phenol zur Saatgutbeize ist bekannt, doch wirken die Bestandteile weder allein noch deren Mischungen ausreichend fungicid, insbesondere nicht gegen die Streifenkrankheit.Process for the preparation of a dry seed dressing The application of mercury oxide and phenol for dressing seeds is known, but the components work neither alone nor their mixtures sufficiently fungicidal, in particular not against the streak disease.

Es wurde nun gefunden, daß ein wirksames Beizmittel gegen die Streifenkrankheit der Gerste aus Quecksilberoxyd und Phenol erhalten wird, wenn man ihre Mischung bis zur Abscheidung von metallischem Quecksilber erhitzt und das Reaktionsprodukt in Talkum imprägniert. Bei der Reaktion bildet sich Oxyphenylmerkurioxyd bzw. dessen inneres Anhydrid. Zur Herstellung des Mittels erhitzt man z. B. 5,4 g Quecksilberoxyd in 1 5 g geschmolzenem Phenol 15 Minuten lang auf etwa 7o bis 8o° C, d. h. bis zum Beginn der Abscheidung von metallischem Quecksilber,. und tränkt damit nach dem Abkühlen 79,6g Talkum. a g dieses Beizmittels auf i ooo g Gerste angewandt, ergaben einen Befall von o % und o,2 % bei der Streifenkrankheit der Gerste, gegenüber einem Befall von 33,8 0/0 bei unbehandeltem Getreide.It has now been found that an effective dressing agent against streak disease in barley is obtained from mercury oxide and phenol if their mixture is heated until metallic mercury is deposited and the reaction product is impregnated in talc. During the reaction, oxyphenyl mercuric oxide or its internal anhydride is formed. To prepare the agent heated z. B. 5.4 g of mercuric oxide in 1 5 g of molten phenol 1 5 minutes to about 7o to 8o ° C, ie until the beginning of the deposition of metallic mercury ,. and soaks 79.6g talc after cooling. ag this mordant applied to i OOO g barley, showed an infection of o and o%, 2% in the stripe disease of barley, against an infestation of 0/0 33.8 for untreated grain.
