Abstract

Herbicides based on an aqueous suspension of from 20 to 50 percent by weight of 1-phenyl-4-amino-5-chloro-pyridaz-6-one or 1-phenyl-4-amino-5-bromo-pyridaz-6-one, from 2 to 10 percent by weight of dispersant, from 0.5 to 5 percent by weight of silica and from 0.5 to 5 percent by weight of a block polymer of propylene glycol, propylene oxide and ethylene oxide, which additionally contain a thiolcarbamate, a chloroacetanilide or a 2,6-dinitroaniline, the weight ratio of pyridazone to thiolcarbamate, chloroacetanilide or 2,6-dinitroaniline being from 4:1 to 1:2, a process for their preparation, and their use for combating undesired plant growth.
