Description

Schädlingsbekämpfungsmittel. Es wurde gefunden, daß die Halogenderivate des Fornialdehyds, z. B. Chlormethylalkohol, Oxychlorm.ethyläffier usw., gute Eignung zur Saatgutbeiz-e besitzen. Diese Stoffe scnädigen nicht das Saatgut nach Art des Formaldehyds :durch Absdheidung von Paraformaldehyd während der Verdunstung der Beizlösung oder durch Verminderung seiner überwinterungsfähigkeit, doch zeigen sie ähnliche fungizide Wirkungen wie der Formalde-hyd. Pesticides. It has been found that the halogen derivatives of formaldehyde, e.g. B. Chloromethyl alcohol, Oxychlorm.ethyläffier, etc., have good suitability for seed dressing. These substances do not damage the seeds in the same way as formaldehyde: by separating out paraformaldehyde during evaporation of the dressing solution or by reducing its ability to hibernate, but they show fungicidal effects similar to those of formaldehyde.

Man verwendet diese Stoffe allein oder in Mischung unter sich oder mit anderen fungt ziden, insektiziden oder inerten Stoffen, z. B. Quecksüberchl#orid, Kupfervitriol, Fornialdehyd usw., nach. Art der Saatgutbeizen oder in anderer Art und zu anderen Zwecken der, Schädlingsbekämpfung und Desinfektion.These substances are used alone or in a mixture with each other or with other acts cidal, insecticidal or inert substances, e.g. B. Mercury excess chloride, Vitriol, formaldehyde, etc., after. Type of seed dressing or in another way and for other purposes of, pest control and disinfection.
