DISPERSIONS OF 2-ALKYL-4,6-DINITROPHENOL ESTERS

Aq. dispersions of 2-alkyl-4,6-dinitrophenol esters (I) contain as stabiliser 0.1-3 (pref. 0.3-1) wt. % of a metal complex dye (II) of the azo or phthalocyanine series. The dispersions are used as fungicides and/ro acaricides or herbicides. Presence of (II) prevents the crystal growth normally occur...

Zusammenfassung:Aq. dispersions of 2-alkyl-4,6-dinitrophenol esters (I) contain as stabiliser 0.1-3 (pref. 0.3-1) wt. % of a metal complex dye (II) of the azo or phthalocyanine series. The dispersions are used as fungicides and/ro acaricides or herbicides. Presence of (II) prevents the crystal growth normally occurring on storage of such dispersions (e.g. a dispersion contg. 10 mu crystals normally contains crystals up to 50 mu long after 2-3 months), which leads to decrease of biological activity.
