To evaluate the herbicidal activity, subjecting the compounds of the invention tested by using a representative range of plants, oats (has), ryegrass

[192]

(I-), Peppers May (am), pea (w), sugar beet (BSs), linseed (I) and mustard (MB)..

[193]

Out two categories of tests, the tests pre-emergence and post-emergence. Pre-emergence tests include spraying a liquid formulation of a compound of the invention on a floor newly seeded with seeds of the plant species.

[194]

Post-emergence tests have two types of tests, i.e., tests of soaking the floor and spray of foliage. In the testing of soaking of the soil, the soil is sprayed with a liquid formulation comprising a compound of the invention after the seeds of the plant species above germinated and in the spray test of foliage, is sprayed plants with such a formulation.

[195]

Formulations used in the above test are constituted by 40 parts by volume of acetone, 60 parts by volume of water, 0, 5 part by weight of a condensation product of alkylphenol/ethylene oxide available under the trade name as Triton-X 155, and by a compound of the invention in varying amounts.

[196]

To sow and allowed to germinate the seeds of plant species mentioned above in a compost by John innate to steam sterilization.

[197]

In the testing of soil spray and dip of the ground, the ground and the ground carrier-seeded plants are sprayed with the equivalent volume 4, 6 liters by ARE and quenched by a volume equivalent to 93 liters by ARE respectively. In the spray test of foliage, seedlings are sprayed by a volume equivalent to 4.6 liters by ARE. It is also used for control studies wherein treated to the ground seeded, ground bearing the planes not subcultured, and plants with the same compositions but which do not have any active compound.

[198]

The phytotoxic effect is determined by determining the applied compounds reducing the fresh weight of the rods and sheets treated plants relative to control plants and to support a regression curve relating to growth inhibition (C. I.) and applied to the dose of the compound. The dose required to achieve 50% growth inhibition and 90% (it is to say the weight of the compound necessary to achieve a reduction of 50 to 90% of the fresh weight of a sheet and plant stem) is shown in table 6 next. Table 6 gives the dose as kilograms per hectare, the X, Y and Z representing doses higher than 11, the Z, 14 and 22, 4 kg per hectare.

[201]

Determined the herbicidal activity of the compounds mentioned in the following tables 7, 8 and 9 by means of a method which differs from that described in the example Xv frames by the following points.

[202]

Applied both compounds in two doses equivalent to 1 and 10 kg/per hectare in the test soil spray and spray of foliage and a dose equivalent to 20 kg/ha in the soak test soil.

[203]

Determining the effects herbicidal compounds in question visually seven days after the spraying of the foliage and the soil soaking (post-emergence test) and eleven days after pulverizing the soil (pre-emergence test), and are recorded on a scale of 0 - 9 (0=none effect and potent herbicidal effect=9). A rate of 2 approximately corresponds to a reduction of 25% of the fresh weight of the stem and leaves treated plants, a rate of 5 corresponds approximately to a reduction of 55% of the weight, and a rate of 9 to a reduction of 95% of the weight, andc.
