  • Patent number: 5707926
    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.

  • Patent number: 5665678
    Abstract: Agriculturally acceptable pesticidally active ingredients, such as herbicides, fungicides, and insecticides of low melting point, typically in the range from about 30.degree. C. to about 130.degree. C. and preferably in the range from about 30.degree. C. to about 90.degree. C. and low water solubility, typically in the range from about 0.01 ppm to about 1000 ppm and preferably in the range from about 0.01 ppm to about 300 ppm are frequently formulated as water-dispersed agrichemically acceptable formulations such as wettable powders (WP), water-dispersible granules (WG), and suspension concentrates (SC) and the like.
