    This invention relates to chemical control of weed and undesirable mortar.
    The object of the invention is to increase the herbicidal effect of the method. based on the use of derivatives of aryloxyalkylcarboxylic acids.
    An example. Preparation of 2-benzyl oxyethyl ester of (6 chloro-2-benzoxazolyloxy) phenoxy propionic acid.
    33.4 g of (6-chloro-2-benzoxazol-1X1) phenoxy-propionic acid are dissolved in 250 ml of anhydrous toluene and 13.1 g of thionyl chloride are added. Thereafter, it is stirred until the end of the separation of the gases at 70 ° C and the excess thionyl chloride is distilled off. 11.6 g of triethylamine and 16 g of benzyloxyethanol are added to the remaining reaction product at room temperature, stirred for 2 hours at 40 ° C, cooled to room temperature, washed twice with 150 ml of 5% sodium hydroxide solution and once 150 ml of water. After drying the toluene solution over magnesium sulphate and distilling off the toluene, the final product is obtained in a yield of 92% as an oil.
    Under the same conditions, other compounds are also prepared, presented in Table. one.
    Substances that represent a viscous oil, characterized by NMR spectra, which are presented in Table. 2
    Pre-emergence processing. Grass seeds (oats, foxtail, chaff, and spring leaves) are sown in pots and applied to the soil surface by spraying the compounds as wettable powders or as emulsifiable concentrates in various dosages. Then the pots are placed for 4 weeks in the greenhouse and the result of the treatment is evaluated on a scale from 0 to 5: O - no damage; 5 - full of death of plants.
    The results of the experiments are presented in Table 3 and 4.
    Post-harvest processing.
    Grass seeds (wild ox, foxtail, bristle, chaff and hedgehog) are sown in pots and grown in a greenhouse. 3 weeks after sowing the plants are sprayed

    proposed compounds in the form of wettable powders or emulsifying concentrates in various dosages. After 4 weeks, the effect of the drug is assessed on a score scale.
    For comparison, the well-known herbicide - (6-chloro-2-benzoxazazyloxy) phenoxy propionic acid isobutyl ester was used. The results of the experiments are presented in table. 5 and 6.
    Compatibility with cultivated plants.
    In a greenhouse, the seeds of sugar beet soybeans and rapeseed are placed in pots. Some of the pots are processed for an hour, the rest are left in the greenhouse until the plants reach the 2-3 leaf stage, and then sprayed with the proposed substances.
    After 4 weeks after application of the substances, it was established that the studied substances in the above cultures did not cause any harm in the pre-and post-harvest treatment in dosages of the active substance up to 2.5 kg / ha (0% damage).
    The results of the post-harvest processing are as follows;
    Herbicide action on the chaff
    The consumption rate is 2.5 kg / ha. Herbicidal effect on wild oats and redberries 5 points.
