Abstract: Aqueous pesticidal agents based on active substance-containing dispersions in combination with water-soluble active substances, which agents contain at least 3 active substances, at least 2 of which are present in the disperse form and at least 1 of which is water-soluble, and contain alkyl ether sulfates combined with ethoxylated fatty alcohols and sulfosuccinic monoesters as surfactants, have a broad range of applications and advantageous properties in use.

Abstract: The invention relates to plant-protection agents which contain one or more active ingredients and which are based on suspoemulsions containing aqueous and organic phases, where the organic phase contains one or more surfactants from the group comprising the ethylene oxide/propylene oxide block polymers having an average molecular weight of 1,000-20,000. The suspoemulsions are subjected to large shear forces. Even thereafter, they exhibit a constant viscosity behavior, in spite of a large number of droplets and a low droplet size.

Abstract: The present application describes herbicidal agents, based on emulsions, which contain two or more active compounds - a water-soluble, salt-like active compound and an active compound which is soluble in organic solvents - a surfactant mixture and a solvent, the surfactant mixture comprising a combination of phenylsulfonate salts, ethoxylated alkyl- (or polyaryl)phenol phosphates, ethoxylated acidic phohsphoric acid esters and alkylphenol polyglycol ether derivatives. These agents are prepared by the action of high shear forces.
