Abstract
Herbicidal active substances from the sulfonylurea series were hitherto mainly formulated as WPs or WGs. The invention relates to novel, storage-stable aqueous suspensions of these active substances, comprising a polyacrylic acid derivative, to processes for their preparation, and to their use in crop protection.
Claims6
An aqueous herbicidal preparation in the form of a suspension or suspoemulsion comprising 0.1-60% by weight of at least one herbicidal active substance from the sulfonylurea series, 0.5-20% by weight of at least one surfactant from the class of the alkali metal or ammonium salts of polyacrylic acid derivatives, 0.01-12% by weight of a dodecyl- or tridecylbenzenesulfonate, and 0-25% by weight of conventional adjuvants from the series of the wetting agents, dispersants, defoamers, thickeners, preservatives and antifreeze agents, and which preparation does not contain herbicidal active substances from the series of sulfonediamide derivatives.
