Description

(54) HERBICIDE STRUCTURE

etc. They are prepared by known methods. The content of active substances in these preparations may be in the range of 0.0001 to 95% by weight (based on the sum of the two components).

Example I. Dapahuchi chamomile plants were harvested in the field and peanutted into pots at the rate of three pot per pot. Planting was performed at the 4-6 and 8-L2 leaves stage. Ethanolamine salt 3, and free 2M-4XP, as well as mixtures of these components were tested.

Evaluation of the herbicidal activity of the proposed composition in comparison with the activity of its individual composting was carried out 7 and 14 days after treatment.

Scale of damage to plants:

1 - slight damage;

 - moderate damage;

3- severe damage;

4- very strong damage;

5 - extremely severe damage;

6 is full of plant death. , 1 The results of the experiment are presented in Table. one.

Example 2. In this test, the potassium salt of 3,6-DPK was used in the form of an emulsifiable concentrate containing 11.3% of the active substance, and the sodium salt of 2M-4XP in vvdv 32% concentrate. From these preparative forms, mixtures were prepared which contain the following weight ratios of the components, respectively: 1:14, 1:28, and 1:56 (in terms of acid equivalents). The odorless ginger was grown in open air compost, and then transplanted into the greenhouse for four days before processing. Planting plants at the 4-6 leaf stage.

The degree of damage to the plants was assessed 23 days after treatment by counting the survivable plants.

The results of the experiment are presented in table. 2

Note: according to the 1 slate of the ntu, herds of 4–6 leaves, and then they were treated with separate compositors of the composition and their mixtures. Ryzulyaty otata are presented in table. 3. The rating scale is similar to that of 1. The results of the experiment were evaluated visually 6 weeks after the treatment according to the following procedure :. O - full of death of plants; 1-4 are intermediate values; 5 - no effect. The results are presented in Table. 4. Table4, the effect of sieurism was also obtained in a field experiment on winter barley using ztano-salts 3,6-PRP and 2M-4XP. Claims of the invention: A herbicidal composition based on a two-com- pact with a nerguskask from a picnic acid refinery and a pictogram of an art of picolinic acid; , alkyl, cation of an organic or inorganic base, and as a derivative of aryloxyalkylcarboxylic acid, a compound of the general formula CHa C1-) H-oSne05 en, where R is hydrogen, alknp or alkali cation is used metal, and the weight ratio of the components of the range ranges from 1: 5 to 1: 120, respectively.
