  • Patent number: 6831041
    Abstract: The present invention relates to oil suspension concentrates based on 2-{1-[2-(4-chlorophenoxy)propoxyimino]butyl}-3-hydroxy-5-(tetrahydrothiopyran-3-yl)cyclohex-2-enone lithium salt and certain formulation auxiliaries and to the use of the oil suspension concentrates as crop protection compositions and in particular as rice herbicides. Preferred formulation auxiliaries are mono- and/or dicarboxylic esters, for example fluid fatty acid esters, anionic surfactants of the sulfonate type, for example alkyl- and alkylarylsulfonates and also sulfosuccinates, and nonionic surfactants of the type of the nonethoxylated or ethoxylated carboxylic acids and esters of mono- or polyfunctional alcohols, for example ethoxylated fatty acids and polyoxyethylene sorbitan fatty acid esters. The oil suspension concentrates described herein are storage-stable and have excellent use properties.

  • Patent number: 6087305
    Abstract: A mixture consisting essentially of:a) one or more dicarboxylic acid esters of the formula IROOC--A--COOR (I)in which the radicals R independently of one another are alkyl groups having 1 to 20 carbon atoms and A is alkylene having 1 to 20 carbon atoms, alkenylene or alkynylene each having 2 to 20 carbon atoms, cycloalkylidene or cycloalkenylidene each having 5 or 6 carbon atoms or phenyleneandb) the product (II) of the reaction of a triglyceride based on carboxylic acids having 2 to 30 carbon atoms and ethylene oxide and/or propylene oxide in the presence of a base,which is useful for the production of crop protection compositions, for herbicidal crop protection compositions, and for controlling undesired plant growth, and spray mixtures comprising the compositions.

  • Patent number: 5486904
    Abstract: The free resin particles which present problems in papermaking are determined according to number and size in order to bind them to the wood fibers by adding assistants and hence render them harmless. For this purpose, a paper stock suspension is prepared and the resin particles are separated from said suspension and then marked with a fluorescent dye and isolated. The light signals emitted by the individual resin particles after excitation are detected for determination of number and size.
