    The invention relates to methods for protecting cultivated plants from undesirable effects of a herbicide, and more specifically to a method for protecting cultivated plants from undesirable effects of a herbicide using a herbicidal COMPOSITION containing a substance that reduces the undesirable effect on a cultus plant herbicide, antidotes.
    The purpose of the invention is to increase the efficiency of the method.
    Example 1. A crushed topsoil sandy soil 5 and coarse washed cement sand, sifted through a 0.475 cm sieve, mix three parts of the soil into one part of the sand in a mass ratio and pasteurize the mixture with hot steam to kill 20 all the pathogenic organisms and natural population of seeds weeds
    The hollow containers (trays) are filled to 0.95 cm from the top of the pasteurized soil mixture, leveled but not compacted and passed under a spray gun equipped with a fixed vane nozzle suspended above a tape that has been adjusted to Driving speed, the Blade nozzle operates at an air pressure of 2800 g / cm s and delivers 25 mp of distilled water in 4.6 seconds. 25.4 cm above the soil surface creates a jet pattern. 45.7 cm wide. The belt speed is adjusted so that 76.2 cm of belt moves per revolution, in 8.3 seconds. Containers with the test soil pass under the nozzle for 4.6 seconds. During Q this time the surface is treated is equal to 0.63 m. The volume of the supplied liquid is equivalent to a dose of 400 liters per 1 ha, and 0 7029 g of a 100% active test compound per 0.63 m is equivalent to a dose of 11.2 kg of the test compound per 1 ha.
    The carrier solvent used for S-alkylthiocarbamate, i.e. The EPTC, and the common antidote compound, is a mixture of 90j80: 2 mixtures of acetone: methanol: dimethylformamide. After the test container is sprayed with the test compound or mixture of compounds, it is immediately emptied into a clean plastic bag with a closed top, the contents are thoroughly mixed, manually shake the bag, and the contents of the bag
    empty back to the test container. After that, the soil is leveled and compacted with hybrid funk-G 4288 wheat, and the soil mixture is covered with a pasteurized, sifted sand of 2.54 cm deep. Then the treated pallets are transferred to a growing room, where they are slightly wetted from above with water, which is necessary to ensure plant growth. The room for upgrading the plants is illuminated with an average light intensity corresponding to .27 lms. on, 1 m surface at a level not growth. The temperature in the greenhouse is maintained from 29 to 30 C during the 16-hour light period and from 20 to 23 C. at night. The relative humidity in the greenhouse averages 50-55% with less than 5% of the greenhouse space.
    The treated pallets are left to grow by plants5 and then periodically inspected for visual identification of wheat damage, if any. Damage is noted as a reduction in growth and / or hormonal curvature when compared with untreated control plants,
     The hormonal lesion is recorded as a curvature of the growing tip of the stem J due to the lack of developing leaves that can. unwrap from growing shoot Continuing apical growth leads to compaction and deformation of the tissues under the apex until it collapses into the surrounding leaf tissue. Hormonal damage can occur in the initial stages of growth of the sun at high concentrations of used S-alkylthiocarbamate or in later stages at lower levels. herbicide concentrations. The curvature may not appear until the growing tip of the stem is above the level of the soil, or it may not appear until the tip divides and gives rise to the formation of a female florets. In addition, a hormonal damage can weaken the support root system so that the entire plant can fall under its own weight.
    Example 2: When EPTP (S-ethyl dipropylthiocarbamate) is used for administration to a plant as described.
    in Example 1, at a concentration of b, 72 kg / ha, without any addition of the antidote compound, 90% of wheat damage is observed, which manifests itself as a reduction in growth and hormonal curvature after 14,25,28 and 42 days. In addition, after 42 days, necrosis also develops, which contributes to the defeat of the cereal culture,
    Example 3. When EPT is used for administration to a plant as described in Example 1, at a concentration of 6.72 kg / ha, and N- (2,2-dimethoxyethyl) -N- (2-propenyl) -2.2 -dichloroacetate-amide - at a concentration of 0.56 kg / ha, i.e. in relation to 12 may. ERTS on 1 ma.ch. after 42 days, the cereal culture is completely healthy and normal, and there are no signs of reduced growth or hormonal curvature of the plants.
    Example 4. When ERTS is used
    for concentration up to plants in a concentration of 6.72 kg / ha and N- (2,2-dimethoxyethyl) -H- (2-propenyl) -2,2-dichloroacetamide in concentration. 1.12 kg / ha, i.e. in respect of 6 ma.ch. ERTS on 1 ma.ch. Compounds — opposite to, as described in Example 1, after 42 days, the cereal culture is completely healthy and normal and there are no signs of reduced growth or hormonal curvature of the plants.
    Example 5. When EPTS is used to administer to plants at a concentration of 1.12 kg / ha and N- (2,2-dimethoxyethyl) -H- (2-propenyl) -2,2- dichloroacetamide at a concentration of 0.187 kg / ha, i.e. at. in relation to 6 ma.ch

    Example 6. When EPTS is used to administer to plants at a concentration of 6.72 kg / ha and N- (1,3-AH-oxolan-2-ylmethyl) -N- (2-propenyl) -2,2-dichloroacetam1ad-c a concentration of 0.373 kg / ha, i.e. in relation to 18 may.
