    1 - The invention relates to chemical IMDs for controlling weeds and undesirable vegetation, namely, herbicidal compositions containing active, substances and auxiliary components. The purpose of the invention is to increase the herbicidal activity of a composition based on aryloxyalkene derivatives of new acids. The herbicidal composition contains, along with active substances, a solvent and surfactants and can be used as such or when diluted with water to the required concentration of the active substance. the composition contains sorpol 335L, sorpol 2926, sorpol 2806B and sorpol .L 550, Sorpol 335L - a mixture of polyoxyethane phenylphenol derivative and alkylaryl sulfonate, Sorpol 2926 - a mixture of polyoxyethyl lenfenilfenolnogo polioksietilensorbitanalkilata derivative, fatty acid derivative and polioksietshten alkylarylsulfonate Sorpol 2806V - mixture polioksiet lenfenilfenolnogo derivative, n lioksietilenalkilarilovogo ether and alkylarylsulfonate polikosietilensorbitanalkilata, Sorpol L 550 - mixture polioksietilenstir shfenilovogo ester polymer polioksietilenstirilfeshshovogo ether, polyoxyethylene fat nokislotnogo derivative and an alkylarylsulfonate, as active substances use the following compounds. Compound 1, Methyl-4- (4- (5-three fluoromethyl-2-pyridyloxy) phenoxy-) -2-pentenoate, t, kip, 143-146 C at 1 mm Hg, Art, (with a certain
    bed)
    Compound 2. Etsh1-4- (4- (5-trifluoromethyl-2-pyridshloxy) -phenoxy) -2-pentenoate, t, kip. 148-151C at 1 mm Hg (with some decomposition),
    Compound 3, g -Byl-4- (4- (5-trifoptermetry I-2-pyridyloxy) -phenoxy) -2-pentenoate, t, kip. 159-1b2 with at 0.8 mm Hg (with some decomposition),
    Compound 4. Ethyl-4- (4- (3-chloro-5-trifluoromethyl-2-pyridyloxy) -feudate and spraying with a predetermined amount of aqueous dispersion obtained by diluting form 1 at the rate of 10 kg / ha of active substance, and 20 days after spraying produced a visual assessment of the growth of weeds, the results obtained are shown in Table 1, with the degree of growth inhibition evaluated on a 10-point scale, where 10 points is complete growth inhibition, 1 point no inhibition. 722 noxy-2-pent. enoate, bk. 162-165C at 1 mm Hg. (with some decomposition). Compound 5. H-Buty-4- (4- (3 chloro-5-trifluoromethyl-2-pyridyloxy) -phenok1Ci) -2-pentenoate, njj 1.5282, Herbicide: the composition can exist in various forms in the following ratio of components, wt.%: Form 1 Active substance 70 Naphtha solvent 20 IIAB - sorpol 335L 10 Form 2 Active substance 10 Solvent - naphtha 80 IIAB - sorpol 292610 Form 3 Active substance 20 Solvent xylene lAB - sorghT 2806B form 4 Active substance Solvent toluene Ethanol. Surfactant - sorpol L550 Example 1, Each business area of 1/30 m is covered with soil to provide conditions for elevated (hilly) terrain. Predetermined quantities of edible chicken millet, radish and soybeans are sown, and then covered with soil containing cereal seeds (grass weeds) such as easily rooting creeping weeds to chloris, chicken millet, and foxtail green (meadow patrick) and t, d, up to a layer about 1 cm thick. After 3 days after sowing, the 1/30 m area of the vessel is covered with soil to ensure the conditions of elevated (hilly) terrain. Pre-determined amounts of seeds of edible chicken millet and soybeans are sown and covered with a layer of soil 1 cm thick. When the plant reaches the edible millet of chicken development stage, characterized by 2.5 leaves, a predetermined amount of water dispersion is applied to the foliage obtained by dividing form 2 at the rate of 0.25 and 0, 1 kg / ha of active Bt. Substances. 20 days after treatment, a visual assessment of plant growth is made. The degree of growth inhibition is assessed according to the same scale as in the example. 1. The results are shown in Table. 2. T of the bar. 2 PRI me R 3. Each vegetative vessel with an area of 1/30 m is covered with soil to ensure conditions of elevated (hilly) terrain. A predetermined amount of chicken seed millet, large rosary, ryegrass perennial Italian and oat is planted and covered with a layer of soil about 1 cm thick. When the grasses reach the development stage, characterized by the appearance of 3-4.5 leaves, they are applied a predetermined amount of water dispersion obtained by diluting form 3 at the rate of 0.5 kg / ha of active substance. 30 days after the treatment, a growth inhibition was visually assessed according to the same scale as in Example 1. The results obtained are shown in Table. 3.. Table 3
