Abstract: Crop-protecting compositions containing isoxazolines or isothiazolines, novel isoxazolines and isothiazolines, and their preparationCrop-protecting compositions which contain isoxazolines or isothiazolines of the formula ##STR1## in which X is oxygen or sulfur, R is hydroxyl or has the meanings given in the description, Z is halogen, nitro, cyano, in each case optionally substituted alkyl, alkoxy, alkylmercapto, cycloalkyl, amino, hydroxymethyl, alkylamino, dialkylamino, alkoxymethyl, aryl or aryloxy and n is an integer from 0 to 5. Novel isoxazolines and isothiazolines of this formula, a process for their preparation, and their use as a protection against phytotoxic secondary effects of herbicides.

Abstract: Isoxazolines or isothiazolines having the formula (I), or their salts, in which (Z).sub.n, X and R have the definition given in the first claim, are useful as safeners against the phytotoxic side effects of herbicides, preferably in cereal crops.

Abstract: Disclosed are compounds of the formula (I): ##STR1## The substituents are disclosed in the specification. The compounds are herbicidal safenets. Accordingly, processes for the preparation and use of the compounds of formula (I) are also disclosed.
