We use the proposed substances up to the concentration in water O, 1–2OOO mg / l. As harvesting substances, the active substances are used at a concentration of approximately 0.00 to 25% by weight at a rate of approximately 0-1.0 kg / ha. The treatment is done, at least as far as two days before the harvest. All of the compounds listed above have a herbicidal effect. fl p and me R 1. Pre-emergence application of the proposed compounds in the c. acetic herbicide. Soil with weeds like amaran- (Amarani: hus reiraiEeans b), yurtulak (PontuEaca oEeracea L), ipoe (D pom et purp urea.), Rosicha I) i -; lap-ici iscnaemum Schreb Mij h EI, millet chicken ( Echi tioch Kae PUsgaEEi L jEBun, foxtail (Setar a taSerl.N) chuf (Cypepus PotundusL) is treated with a composition of 50O mg / l, based on 11 kg of active principle per 1 ha. After two pedals, after processing, the determination of weeds is determined; The ethyl sulfates are presented in table. 1. PRI mme R 2. Post-harvest application of the proposed compounds as a herbicide. The weeds indicated in the previous page, the streamer, are treated with a solution with a concentration of LOOO mg / n using a spray bottle to drain the juice from the leaves in drops. The percentage of weed destruction was determined after two weeks. Results prnv, unit in table. 2. EXAMPLE 3. The herbicidal effect of 1, 1; 4,4. Tetroxide 2, 3-digi, apo-.5,6 i: fvretil ™ l: 4-insins is confirmed by the destruction of algae (and tichaniTiici cpqssipes with using its solution with the concentration of the named compound LOOO mg / l of water. P r and m 3 p 4. G1Rimene1-above of the proposed compounds as 1 rbl1Hyd of selective action.With the destruction of weeds before the occurrence of sprouts, the soil is moistened with a solution at the rate of 2.2 KiVra at a concentration of 50 mg of the active. The substance per 1 bilipolar of the treatment is given in Table 3. PRI me R 5. The use of the proposed compounds as e desiccants and cotton defoliants. Cotton plants (Qo55LipsUm h4r5utu & iL) at the first true leaf stage are sprayed with a solution with a concentration of 6000 mg of the active substance per p

using a spray bottle to allow the liquid to drip off. The results of processing are given in table. four.

Example 6: Effect of defoliation and prevention of overgrowth of mature cotton due to treatment with the proposed compounds.

Mortar cotton with 4 5 mature seed boxes until liquid drains is treated with solutions of the proposed compounds. The degree of defoliation is determined after 10 days, and the prevention of overgrowth is determined after 30 days. The results are shown in Table. five.

Example. Solutions with a concentration of 4000 mg of active substance

1 L of water and 1OOO mg / p are sprayed to the liquid with the tops of the tops of the potatoes, 10 days after o6pa6oiKii with both solutions reach the destruction of the tops of the tops.

Example Removal of citrus fruits.

The solutions of 1,1,4,4-tetroxide 2,3-dihydro-5, 6-dimethyl-1,4 dit11pna with a concentration of 100, 50 and 25 5G of the active substance in 1 liter of water are sprayed with a branch of an orange tree with fruits until the solution drains. After 7 days, the degree of fruit falling on the average T5 strength is determined. The results of processing are given in tab. 6
