Abstract: The invention relates to methods of separating compounds of interest from mixtures using high performance liquid chromatography (HPLC). An initial separation of a sample of a mixture is performed to predict a retention time and elution time for the compound of interest on a preparative scale HPLC column and, optionally, to verify that an expected compound of interest is present in the mixture. Preparative scale HPLC is then used to separate and collect at least a portion of the compound from the mixture using the predicted elution time of the compound.

Abstract: A method of accelerating the decomposition of an isoxazole and/or a dione pesticide by contacting them with halogen and/hypohalite. A crop seed containing a halogen and/or hypohalite within the seed or at its surface or in a coating on the seed.

Abstract: Substituted-1-arylpyrrole compounds of general formula (I) below, are useful as pesticides, in particular for the control of insects, arachnids, and nematodes. Processes to make the compounds and intermediates used for their preparation are described. Additionally, compositions containing the compounds and methods of use therefore are provided. Preferred compounds are the compounds of general formula (I) ##STR1## wherein typically preferred substituents are: X is halogen or a group R.sup.5 S(O).sub.n, in which n is 0, 1, or 2 and R.sup.5 is CH.sub.3, CF.sub.3, CCl.sub.3, CF.sub.2 Cl, CFCl.sub.2, CF.sub.2 Br, CHF.sub.2, CHCl.sub.2 or CHClF;R.sup.1 is H, F, Cl, Br, OCH.sub.3, SCH.sub.3, or CH.sub.3 optionally substituted;R.sup.2 is CN;R.sup.3 is H, F, Cl, Br, OCH.sub.3, or CH.sub.3 optionally substituted;Y is CF.sub.3, CF.sub.3 O, H, F, Cl or Br;X.sup.1 and X.sup.4 are individually H, F, Cl, Br, CH.sub.3, OCH.sub.3 or SCH.sub.3 ; andX.sup.2 and X.sup.3 are each H.
