    • 专利摘要:
    The acylamide derivatives of the formula I below are suitable for use as a counter-agent, "antidote" or "safener" for protecting cultivated plants against the phytotoxic action of herbicides. Crops suitable in this respect are preferably millet, cereals, rice, maize and soya, and suitable herbicides are chloroacetanilides and thiolcarbamates. The acylamide derivatives have the formula I <IMAGE> (I) in which X is oxygen, sulfur, -SO- or -SO2-; R1 is C1-C6- halogenoalkyl, C1-C6-cyanoalkyl or C2-C6-halogenoalkenyl; R2 and R5 independently of one another are hydrogen, C1-C4-alkyl, C1-C4-halogenoalkyl, C2-C4-alkenyl, C2-C4-alkynyl or C2-C4-alkoxyalkyl; R3 and R4 independently of one another are hydrogen, C2-C4-alkenyl, C2-C4-alkynyl, cyano, C2-C4-alkoxyalkyl, -COOR8, -CO-NR9R10 or C1-C4-alkyl which is unsubstituted or substituted by halogen, cyano or -CO-A; R6 and R7 independently of one another are hydrogen, halogen, C1-C4-alkyl, C1-C4-alkoxy, C1-C4-halogenoalkyl or C1-C4-halogenoalkoxy, A is C1-C4-alkyl, C2-C4-alkenyl, C1-C4-alkoxy, C3-C4-alkenyloxy, C3-C4-alkynyloxy or -NR11R12; R8, R10 and R12 independently of one another are hydrogen, C1-C4-alkyl, C3-C4-alkenyl, C3-C4-alkynyl or C3-C4-alkoxyalkyl; and R9 and R11 independently of one another are hydrogen, C1-C4-alkyl, C3-C4-alkenyl, C1-C4-alkoxy, C3-C4-alkynyl or C3-C4-alkoxyalkyl, it being also possible for R9 and R10 and also R11 and R12, together with the nitrogen atom linking them, to form a 5-membered or 6-membered saturated heterocyclic structure which can, if desired, contain an oxygen or sulfur atom or an -NH- or -N(C1-C4-alkyl)- bridge as a member of the ring.

    专利说明:

    and the counterblower was applied together as a reservoir mixture in the experiment before germination.
    Plastic container (25x17x12 cm was filled with sandy clay soil and corn variety varieties LG5 were sown. After covering the seeds with earth, sprayed the test compound together with the herbicide as a diluted solution of the tank mixture as a countermeasure. 21 days after the application, the protective effect was evaluated di in percent. As a comparison, plants treated with only a herbicide (no protective effect), as well as untreated samples (100% protective effect) served.
    The effectiveness of the protective effect of compound 1.1 when using H-chloroacetyl-H- (2-methoxy-1-methylethyl) -2,6-dimethyl-aniline as a herbicide is presented in Table. one.
    test plants used cucumbers RUZU 00482-0220. In the experiment, before the germination of the seedlings in the form of a reservoir liquid, a herbicide was applied and the test was assessed, as in experiment 1, 3 weeks after application, and a protective effect was given in percent.
    The results of the experiment are given in table. 2
    Example 3. Comparative.
    According to the method described in example 2, the protective effect of the active substance was compared in accordance with the invention.
    ABOUT
    CO-CHClj
    and known contra (compound A)
    N-chloro-acetyl-N- (2-methoxy-1-methylethyl) -2,6-dimethylaniline (AA herbicide) and M-chloroacetyl-H- (2-methoxy-1-methylethyl) were used as herbicides. ) -2-ethyl-6-metsht-aniline (herbicide BB) “As
    Comparison of the effects of compounds 1.1 and A on corn sowing when treated with AA and BB herbicides shows that the active substance 1.1 always has a more protective effect than the compound Ac for all tested ratios of the mixture and consumable norms.
    when using the active substance 1.1, it is always reduced to the permissible degree, while when using compound A, the protective effect for agrochemical purposes is most often
    remains insufficient.
    When using the compound of formula 1 against the damaging effects of agrochemicals, various methods and techniques are used.
    Seed treatment
    a) Seed treatment with active substance in the form of a wetting powder by shaking in a vessel until it is evenly distributed on the surface of the seed (dry treatment). About 10-500 g of the active substance of the formula I (40 g - 2 kg of wettable powder) are used per 100 kg of seed.
    b) Etching by pouring seeds or broth with 50-3200 ppm of the active substance of formula I for 1-72 hours and in the appropriate case of subsequent drying of the seeds (etching by immersion) „
    Seed treatment or treatment of germinated seedlings are the preferred application methods, since the processing of the active substance is completely directed to the target culture. As a rule, 10-500 g of active substance per 100 kg of seeds are used, and depending on the technique, which allows the use of other active substances or microadditives of nutrients as an additive, concentrations may deviate to one side or the other from these (re-dressing).
    Application from the reservoir mixture.
    A liquid ready preparation is used - a mixture of contra and herbicide in the ratio from 10: 1 to 1:30 immediately after sowing or to a depth of 5-10 cm.
