Description
Die Erfindung betrifft den im Patentanspruch gekennzeichneten Gegenstand.The invention relates to the subject matter characterized in the patent claim.
Es ist bekannt, als Saatgutbeizmittel Quecksilberverbindungen zu verwenden. Diese befriedigen zwar hinsichtlich ihrer Wirkung, sind aber toxikologisch sehr bedenklich. Demgegenüber zeichnet sich das erfindungsgemäß zu verwendende 2-(2-Chlorphenyl)-benzimidazol bei mindestens gleicher Wirksamkeit durch sehr geringe Toxizität aus. Beispielsweise beträgt bei Mäusen die LD50 (oral) mehr als 4 g/kg.It is known to use mercury compounds as a seed dressing agent. Although these are satisfactory in terms of their effect, they are toxicologically very questionable. In contrast, the 2- (2-chlorophenyl) benzimidazole to be used according to the invention is distinguished by very low toxicity with at least the same effectiveness. For example, the LD 50 (oral) in mice is more than 4 g / kg.
Es ist auch bereits beschrieben worden, daß in 2-Stellung substituierte Benzimidazole, u. a. 2-(2-Chlorphenyl)-benzimidazol, als Wirkstoffe gegen Pilze verwendet werden können (BE-PS 668024). Aus den Ausführungen über die Pilze, die gemäß der belgischen Patentschrift bekämpfbar sind, ist jedoch nicht abzuleiten, daß gegen die bekanntermaßen schwierig zu bekämpfende Art Fusarium nivale Mittel auf der Basis von 2-(2-ChlorphenyI)-benzimidazol vorteilhaft angewendet werden können.It has also already been described that benzimidazoles substituted in the 2-position, i.a. 2- (2-chlorophenyl) benzimidazole, can be used as active ingredients against fungi (BE-PS 668024). From what has been said about the mushrooms, according to the Belgian patent can be challenged, but it cannot be inferred that it is against the known Difficult to control species Fusarium nivale means based on 2- (2-chlorophenyI) -benzimidazole can be used advantageously.
Es sind auch bereits quecksilberfreie Saatgutbeizmiitel in den Handel gekommen, die eine gute Wirksamkeit zeigen, beispielsweise auf der Basis von Benomyl. Dieser Wirkstoff wird in der Praxis mit 100 g pro 100 kg Roggensaatgut angewendet, um einen zuverlässigen Schutz gegen Fusarium nivale zu erzielen. Dagegen wird erfindungsgemäß bereits mit 20 g 2-(2-Chlorphenyl)-benzimidazol pro 100 kg Roggensaatgut eine 100%ige Schutzwirkung gegen Fusarium nivale erreicht.There are also already mercury-free seed dressings come on the market that show good effectiveness, for example based on benomyl. In practice, this active ingredient is used with 100 g per 100 kg of rye seed to ensure reliable results To achieve protection against Fusarium nivale. In contrast, according to the invention, as little as 20 g of 2- (2-chlorophenyl) benzimidazole 100% protection against Fusarium per 100 kg of rye seeds level reached.
Für das Verfahren gemäß der Erfindung wird der Wirkstoff 2-(2-Chlorphenyl)-benzimidazol mit üblichen Träger- und Hilfsstoffen zu gebräuchlichenFor the method according to the invention, the active ingredient is 2- (2-chlorophenyl) -benzimidazole with usual Carriers and auxiliaries too common
