The given property determines the possibility of its use in agriculture and other branches of the national economy. The proposed compound is not described in the literature.

Close analogues in terms of structure and action are: 1. Sodium humate-standard 1, its description is given in the literature (1), it is used in agriculture to increase the productivity of various crops. In terms of its biological activity, the standard is significantly inferior to the declared compound in terms of the productivity of the beginnings of corn, peas, and winter wheat (tables 1, 2). 2. Succinic acid - analog 2 (for sage), is used in agriculture to increase the energy of germination and germination of seeds, as well as to increase the productivity of agricultural crops (2, C). Succinic acid is also inferior in activity to the compound to be claimed.

C. Picolinic acid - analog 1 (for corn), has the properties of a plant growth regulator (C). But picolinic acid when spraying plants during the growing season can cause plant burns. It is toxic and insufficiently effective when used on clary sage in comparison with the declared compounds (Table 2). ch 4. Chlorohydrate C - methylaminosulfolane analogue (for corn, sage, wheat, peas and sugar beet), which has the properties of a plant growth regulator |5). (at)

The task of the invention is to obtain a new highly effective and environmentally safe plant growth regulator.

The set task is achieved by the synthesis of the salt of aminosulfolane and picolinic acid of formula 1: their

The proposed compound is obtained by the interaction of 3-methylaminosulfolane and picolinic acid at a temperature of 20-787C in ethanol. (Se)

The structure of the proposed compound was confirmed by elemental analysis and IR spectra taken on a ZHRESOKO-M-80 spectrophotometer.

The presence of absorption bands: cher, - group at 1135-1325cm"!, CO-group at 1385cm"!, С-М group at 1585cm"" testify in favor of this structure. The invention is illustrated by the following examples:

Example 1 :c» Method of obtaining a salt of 3-methylaminosulfolane and picolinic acid. In a three-necked reactor with a capacity of 2 liters, equipped with a reflux condenser, a dropping funnel and a mechanical stirrer, dissolve 123.1 g (1 mol) of picolinic acid in 5500 ml of ethanol, and over the course of three minutes, with thorough mixing, add a solution of 149.2 g (1 ml) from the dropping funnel b ) of 3-methylaminosulfolane in 200 ml of ethanol. The reaction mass is boiled for 45 minutes, the solvent is evaporated, the residue is washed with 2-50 ml of acetone. The yield of the salt of 3-methylaminosulfolane and - picolinic acid is 266.8 g (9895), the melting point is 131-1327C (from methanol). - Found, 90: C - 48.6; H - 6.1; M - 10.3; 5 - 11.9; C44Ni6M20.45.

Calculated because: C - 48.52; H - 5.92; M - 10.28; 5 - 11.77. o Example 2 syu Effect of drugs on the productivity of winter wheat, sugar beet, peas.

The object of research is winter wheat from the village of Myronivska 808, sugar beet from the village of Slavyanskyi, peas from the village of Agrariy.

The place of the experiment is an inpatient facility of the National Agrarian University in KSP "Sokilcha" 5B, Popilnya District, Zhytomyr Region.

Soil - (F) Methods of conducting experiments. Pre-sowing seed treatment was carried out with a working solution of preparations with a calculation rate of 2Ol/t of seeds for peas and winter wheat and 8Ol/t of seeds for sugar beet. Vegetative plants were treated with a working solution of drugs at the rate of 50 Ол/ha in the phase of the beginning of budding 60 (peas), the beginning of emergence into the tube (winter wheat) and the beginning of leaf closure in the row (sugar beet).

The area of the accounting plots is 25 m2, repetition is four times.

The scheme of the experiments and the results of the studies are shown in Table 1.

As can be seen from the data in Table 1, the use of the declared compound contributes to a significant increase in the yield of winter wheat, peas and sugar beet both during seed processing and during growing season: 65 - by 15.2 and 16.1905; 12.1 and 13890; 12.9 and 14.295 (relative to the control); -nav,1 and 8,590; 5.7 and 7.090; - and - (relative to the standard);

-by 10.01 and 9.995; 56.81 8.1 Fo; 6.2 and 8.090 (relative to the analogue).

The use of this compound (Z-methylaminosulfolane salt and picolinic acid) during the cultivation of sugar beet leads not only to an increase in the yield of root crops, but also to an increase in sugar content, as a result of which the sugar collection increased compared to the control by 14.5 and 15.6905. control control | of root crops /95 t/ha| 95 c/ha 95 | c/ha c/ha of control control
