by reaction with a strong base, for example, an alkaline hydride, an alkaline amide or lower alkaline alkaloles, and in the latter case, the resulting lower alcohols must be removed by azeotropic distillation. The selection of alkaline salts of the formula (3) is unnecessary. They can, immediately after preparation, be reacted with compounds of formula (4) in an inert solvent, for example toluene, xylene, tetrahydrofuran or dimethylformamide.

Depending on the conditions under which the reaction is carried out, compounds (1) are formed either as free bases or as their salts (2). Salts can be converted into free bases in the usual way, for example, by reacting with an alkali, for example sodium hydroxide. or potassium, potassium carbonate or sodium, ammonia or similar alkali. The compound in the form of a base can be obtained by reaction with acids, for example, inorganic, such as hydrochloric acid, hydrobromic acid, hydroiodic acid, sulfuric acid, nitric phosphoric acid, or organic acid such as acetic acid, propionic acid, oil, glycol, benzoic acid, toluene sulfonic acid. or convert high alkylbeneolsulfonate acids, such as dodecylbeneolsulfonic acid, into valuable acid addition salts. For comparison, well-known compounds are given, which are used as plant growth regulators. fii-CHj-Hj-e-cnj o - (; H2-cn (5I2 V3,, 2-CH .- / O / - «i WNOj (H2 f I W.W K-CH2-W- / OGS1 HNO, , - (s. / I /; r N F-CHj-CH-Ujy-Cl HNOj // II j N - (SH-ec-CHi H / I of 0 Enz 6. „Greenhouse tests. a) B small vessels made of waxed paper with a capacity of 200 cm sow plants separated by varieties. The substrate is clayey sand, which has been fertilized with a humus content of 1.5% and a pH of 5.8. For pre-emergence treatment, the chemical is applied immediately after sowing, affecting the seeds that are not yet swollen, but only slightly covered with earth, and post-emergence treatment is carried out when It does not reach a height of 3-10 seconds depending on the shape of the plants. The substance to be tested is fed with a water-spray nozzle. The plants, depending on the temperature requirements, are placed either in warmer or cooler places of the greenhouse. lasts several weeks, depending on the development of different plant varieties and the possibility of their growth in small vessels. Production evaluation by visual inspection according to the scheme from O to 100 (O means that no changes occurred during plant development, 100 - inhibition, equal the destruction of plants). Plant height is measured in centimeters. pax. b) Testing according to the Neubauer system. In a greenhouse, in a peat substrate well fertilized with nutrients, plants are sown. A growth regulator is used in an aqueous solution or as a dispersion at different rates of application on the soil and on the leaves. The soil is treated by spraying on the day of sowing the test substances on the soil surface, the leaves by spraying when the plant reaches a height of 8 cm. Within 18 days after treatment, the plants develop much worse than untreated ones. For comparison, the height of 1CO plants from the keicdah of the treated row is measured. The imidazole compounds used as the comparative compound have no effect. c) Testing according to the system of Micherlich. Under conditions similar to those in the open field, vegetation tests are carried out with two-barley in large vessels with a capacity of 10 liters. Plants are grown in sandy loam fertilized with ammonium nitrate. (1.5 g) and secondary acid potassium phosphate (1 g). Then, the test substances are pipetted in the form of an aqueous solution or dispersion over the soil surface of the seeded plies. At a plant height of 28 cm, a known compound No. 42 is applied to the leaves, which, when applied to the soil during the growing season, is inactivated. Tests in the open field Tests were carried out on small cases in order to study the development of winter rape varieties under the influence of the proposed product. Leaves are treated a few weeks after sowing with a sprinkler driven by a tractor. Water is a carrier medium for a finely distributed active principle. Observation time: from the beginning of treatment through the winter to the beginning of flowering. The stages of plant development are fixed at different time intervals after treatment. Tests in greenhouses and in the open run show that the proposed distribution, especially with active number 4, is a regulator of the remaining numerous species of different plant families. The proposed connection in comparison with the known (42) is the same

active, and in some cases effective combat. A large number of plant species do not react or react poorly to treatment by known means (No. 43-46),

The proposed agent specifically affects the growth of winter rape. It allows growth to be delayed during the growing season and prevents a premature transition to. generative stage and thereby increase the ans for overwintering and productivity of plants. At the same time, undesirable plants occurring in rapeseed plantations are so slowed down in growth that they cannot stifle outgrown cultivated plants.

The proposed agents can be used in the form of solutions, emulsions, suspensions, powders, pastes and granules, depending on the purpose of the application; in all cases, a fine and uniform distribution of the active principle should be ensured. The preparations are prepared in a known manner, for example, by adding a solvent and / or filler to the active material, in appropriate case using emulsifying agents and dispersants, and in the case of using water as a diluent, other organic solvents can also be used as auxiliary solvents. In addition, solvents such as aromatic hydrocarbons (e.g. chlorobenzenes), paraffins (e.g. petroleum fractions), alcohols (e.g. methanol, butanol), amines (e.g. ethanolamine, dimethylformamide) and water are generally auxiliary; carriers, such as ground rocks (for example, kaolins, alumina, tal, synthetic rocks of crushed rocks (for example, highly dispersed silica, silicates); emulsifiers, for example, non-ionic and anionic (in particular, polyoxyethylene-fatty alcohol, alkyl sulfonates) ) and dispersants like lignin, spent sulphite liquor and methylcellulose.

Preparations usually contain 0.1- 95% by weight of active ingredient, preferably 0.5-90.

Preparations or formulations derived from them, for example solutions, emulsions, suspensions, powders, pastes or granules, are used before germination, after germination or as a disinfectant.

The consumption rate, depending on the desired effect of 0.2-5 or more, preferably 0.5-2 kg of active ingredient per 1 hectare.

The proposed agents may be introduced along with other active principles, such as, for example, the herb

cides, insecticides, plant growth regulators and fungicides or may be mixed with fertilizers. Mixing with plant growth regulators in many cases leads to an expansion of the spectrum of action. With the introduction of a certain amount of such mixtures with a growth regulator. A synergistic effect also occurs, i.e. the effect of the combined products is greater than the sum of the actions of the individual components.
