- alkali, alkaline earth, ammonium salts of aromatic sulfonic acids e.g. Lignin, phenol, naphthalene and dibutylnaphthalenesulfonic acid, as well as of fatty acids, alkyl and alkylarylsulfonates, alkyl, lauryl ether and fatty alcohol sulfates, as well as salts of sulfated hexa-, hepta- and octadecanols as well as of fatty alcohol glycol ethers, condensation products of sulfonated naphthalene and its derivatives Formaldehyde, condensation products of naphthalene or naphthalenesulfonic acids with phenol and formaldehyde, polyoxyethylene octylphenol ether, ethoxylated isooctyl, octyl or nonylphenol, alkylphenyl, tributylpheny
- Powders, materials for broadcasting and dusts can be prepared by mixing or grinding the active substances together with a solid carrier.
- Granules for example coated granules, impregnated granules and homogeneous granules, can be prepared by binding the active ingredients to solid carriers.
- Solid carriers are mineral soils such as silicas, silica gels, silicates, talc, kaolin, limestone, lime, chalk, bolus, loess, clay, dolomite, diatomaceous earth, calcium and magnesium sulfate, magnesium oxide, ground plastics, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, Urea and vegetable products such as flour, tree bark, wood and nutshell flour, cellulose powder or other solid carriers.

- the concentrations of the active ingredients I in the ready-to-use preparations can be varied over a wide range.
- the formulations generally contain 0.001 to 98% by weight, preferably 0.01 to 95% by weight, of at least one active ingredient.
- the active ingredients are used in a purity of 90% to 100%, preferably 95% to 100% (according to the NMR spectrum).
- the compounds I according to the invention can be formulated, for example, as follows:
- V 3 parts by weight of the respective compound I are mixed with 97 parts by weight of finely divided kaolin. In this way, a dust is obtained which contains 3% by weight of the active ingredient.
- VI 20 parts by weight of the respective compound I are intimately mixed with 2 parts by weight of calcium salt of dodecylbenzenesulfonic acid, 8 parts by weight of fatty alcohol polyglycol ether, 2 parts by weight of sodium salt of a phenol-urea-formaldehyde condensate and 68 parts by weight of a paraffinic mineral oil. A stable oily dispersion is obtained.
- the substituted phenoxyacrylic acid derivatives I can be mixed with numerous representatives of other herbicidal or growth-regulating active ingredient groups and applied together.
- the application rates of active ingredient are 0.001 to 3.0, preferably 0.01 to 1.0 kg / ha of active substance (a.s.), depending on the control target, season, target plants and growth stage.
- Example 1 3- (4-Chloro-2-fluoro-5- (1-methoxycarbonyl-l-vinyloxy) phenyl) -6-trifluoromethyl 1-2, 4- (IH, 3H) pyrimidinedione
- the herbicidal activity of the substituted phenoxyacrylic acid derivatives of the formula I could be demonstrated by greenhouse experiments: plastic pots with loamy sand with about 3.0% humus as substrate served as culture vessels. The seeds of the test plants were sown separately according to species.
- the active ingredients suspended or emulsified in water were applied directly after sowing using finely distributing nozzles.
- the tubes were lightly sprinkled to promote germination and growth, and then covered with clear plastic hoods until the plants had grown. This cover causes the test plants to germinate evenly, unless this was affected by the active ingredients.
- test plants For the purpose of post-emergence treatment, the test plants, depending on the growth habit, were first grown to a height of 3 to 15 cm and then treated with the active ingredients suspended or emulsified in water. The test plants were either sown directly and grown in the same containers or they were first grown separately as seedlings and transplanted into the test vessels a few days before treatment.
- the application rate for post-emergence treatment was 1.95 and 3.9 g aS / ha.
- the plants were kept in a species-specific manner at temperatures of 10 to 25 ° C and 20 to 35 ° C.
- the trial period lasted 2 to 4 weeks. During this time, the plants were cared for and their response to each treatment was evaluated.
- Evaluation was carried out on a scale from 0 to 100. 100 means no emergence of the plants or complete destruction of at least the aerial parts and 0 means no damage or normal growth.
- the plants used in the greenhouse experiments are composed of the following types:
- the compound from Example 2 showed at application rates of 3.9 and 1.95 g / ha a. S. in comparison to the compound of comparative example A, a significantly better tolerance to the wheat crop (TRZAW) with an at least equally good herbicidal action on dicotyledonous harmful plants.
- TRZAW wheat crop
