in which R is lower alkyl, cyclohexyl, unsubstituted or substituted halogen. After 10-14 days it has been found that mixtures I + V, P + V, III + V, and IV + V will have a better herbicidal effect than individual active principles, with the same compatibility relative to the cultivated plant.

Indicators of herbicidal activity, points, are given in table. one.

Note. O - without damage; 100 is complete.

NOM is phenyl, and the weight ratios of the components are respectively from 1: 10 to 10: 1.

Pr "Measures 1. In the greenhouse conditions, test plants were treated at a height of 3 to 15 cm by separate active principles and their mixtures:

I.3-Isopropyl-2,1,3-benzothiadiazine- (4) .2,2-dioxide 0,75; one; 1.5; 2.25 and 3 kg / ha;

II. Diethanolamine salt of 3-isopropyl-2, 1,3-benzothiadiazino- (4) -2,2-dioxide 0.5; 0.25; 0.75; one; 1.5; 2.25 and 3 kg / ha;

III. Dimethylamino salt of 3-isopropyl-2, 1,3-benzothiadiazinone (4) -2,2-dioxide 0,5; 0.75; 1.5; 2.25 and 3 kg / ha;

IV. Sodium salt of 2,1,3-b.Nzotiadiazinone- (4) -2,2-dioxide 0,75; one; 1.5; 2.25 and 3 kg / ha;

V.4-amino-6-treg-butyl-3-methylthio-4,5-dihydro-1, 2,4-triazin-5-o, n 0.25; 0.75; one; 1.5; 2.25 and 3 kg / ha;

I + V. 0.75 -1- 0.25: 2.25 + 0.75, 0.75 + –L 0.75, 0.75 + 2.25 kg / ha;

II + V. 0.5 4- 0.25, 0.25 + 0.75, 2.25 -f -I- 0.75, 0.75 + 0.75, 0.75 + 2.25 kg / ha ;

III + V. 0.5 + 0.25, 2.25 + 0.75, 0.75 -f -1- 0.75, 0.75 + 2.25 kg / ha;

IV + V. 0.75 + 0.25, 2.25 + 0.75, 0.75 + -f 0.75, 0.75 -1- 2.25 kg / ha.

Example 2. In the greenhouse vegetah. Tation vessels were filled with clayey sandy soil into which seeds were sown. Then this soil was treated with the following separate active principles and their mixtures:

I.Z-Isopropyl-2,1,3-benzothiadiazinone- (4) -2, 2-dioxide 2.5 kg / ha;

II.4-amino-6-g / e-butyl-3-methylthio-4,5-dihydro-1, 2,4-triazin-5-one 0.25 kg / ha;

I + ii. 2.5 -1- 0.25 kg / ha.

After 3-4 minutes, we found that the mixture 1 -I-IO: produced a better herbicidal effect than the individual active principles I and II, n: for the same quality with respect to culture.

Indicators of herbicidal activity, balls, are given in table. 2 and 3.

Example 3. In the greenhouse and field conditions, different plants were treated at a height of 2-12 cm with the following separate active principles and their mixtures:

I.3-Isopropyl-2,1,3-benzothiadiazinone- (4) -2, 2-dioxide 0.9 kg / ha;

II.4-Ami1NO-6-greg-butyl-3-methylthio-4,5-dihydro-1, 2,4-triazi, n-5-one 0.1 kg / ha;

I + ii. 0.9 + 0.1 kg / ha.

After 10-14 days, it was found that mixture I + II exerted a better herbicidal effect than the individual active principles I and II, with the same compatibility with respect to culture.

The results are shown in Table. 4 and 5.

Example 4. Under greenhouse conditions, the vegetative vessels were filled with unclinched clay soil in which seeds were sown. Then this soil was treated with the following active principles and their mixtures:

I.3-Isopronyl-2,1,3-benzothiadiazino-(4) -2, 2-dioxide 2.5 kg / ha;

II.4-amino-6-greg-butyl-3-methylthio-4,5-dihydro-1, 2,4-trnazin-5-one 0.25 kg / ha;

I + ii. 2.5 N - 0.25 kg / ha.

After 3-4 pedals, it was found that mixture I + II exerted a better herbicidal effect than the active patches I and II with the same compatibility with respect to culture.

The results are given in table. 6
