    Abstract: New and valuable herbicide comprising 1-phenyl-4-amino-5-chloro (or -5-bromo)-pyridazone-(6) which contains from 10 to 65 weight % of the active ingredient in the form of an aqueous suspension and, as dispersant, a condensation product of sulfonated phenols free from condensed ring systems with urea and formaldehyde in a molar ratio of 1:1 to 1.5:1.7 to 2.2, which condensation product has been after-treated with phenols and formaldehyde. The dispersion is extremely stable, even after prolonged storage periods. It can be readily mixed with other plant protection agents upon dilution. No dust problems occur when the spray liquors are prepared for use.
