    • 专利摘要:
    The herbicide contains, as active substance, a compound of the formula I. The herbicide is prepared by mixing the carrier with a compound of the formula I. The compound of the formula I can be obtained by reacting a compound of the formula II with a compound Hal-Z or a suitably substituted phenoxypropionyl halide with a compound HYZ. The substituents in the compounds have the meanings given in patent claim 2. <IMAGE>

     l Example 3. Selectivity of action. Analogously to example 2, an experiment was conducted with cultivated plants: co, peanuts, beans, flax, cabbage, cucumbers, sunflower, tobacco, carrots, celery, beets, barley, wheat, etc. It was found that at a dose of 2.5 kg / ha crop plants are virtually undamaged. Selectivity of action also appears in pre-emergence applications. Claims of the invention A herbicidal agent containing an aryloxyalkanecarboxylic acid derivative as an active substance, as well as auxiliary components selected from the group of liquid or solid carriers, surface-active 20 substances, characterized in that, in order to enhance the herbicidal effect, it contains an aryloxyalkane 12 as a derivative
