 For comparison, Table 1 also shows the growth suppression values in the case of a mixture of Accent with Frigate and in the case of a mixture of Accent with corn oil pre-mixed with Sorpol 3815K. Inhibition of growth when one Accent is used is taken as 0%.

 As can be seen from table 1, the enhancing effect of herbicidal activity achieved by combining Frigate with corn oil is not an additive effect of each enhancing effect that each component has independently, but is a wonderful synergistic effect.

Test Example 2
The seeds of the blood dewdrop / Digitaria sanguinalis L. / are sown in 1/1000000 ha pots filled with upland / upland / soil. When the blood dewdrop plants reach the 2.5 - 3.0 leaf stage, Accent / water-dispersible granules / are diluted with 200 l / ha of water containing a predetermined amount of Frigate and a predetermined amount of corn oil, which is pre-prepared by mixing with a predetermined amount of Sorpol 3815K, and applied to the foliage of plants using a small spray.

 On the other hand, 4 days after the treatment, corn plants were visually examined for damage (degree of discoloration and yellowing), and the results are also presented in table 13/0 = no damage - 5 = some damage /.

Example 14 biological tests
The seeds of blood dewdrop (Crabgrass) (Digitaria sanguinalis L.) and ragweed (Ambrosia Artemisiifolia L.) were sown in pots with an area of 1/1000000 ha, filled with soil from the upper layer (upland) and located in a double system. When plant development has reached a certain stage (blood dewdrop: stage 3.0 leaves and ragweed: stage 3.8-4.0 leaves), a wettable powder containing compound A and pyridate as the herbicidal active ingredient (commonly used name) was diluted water (200 l / ha) containing a certain amount of activity-enhancing composition of the present invention obtained in Example 73 above, and applied to the leaves of plants using a small spray.

 19 days after treatment, the inhibition of plant growth was evaluated by visual observation in the same manner as in example 1 biological tests; the results are shown in table 14.

 For comparison purposes, Table 14 also shows growth inhibition for the case of mixing said wettable powder with Frigate (trade name) (growth inhibition in the case when only wettable powder was applied was 0%).

 As can be clearly seen from the results shown in table 14, the herbicidal activity of the herbicidal composition with increased activity obtained by adding the activity-enhancing composition of the present invention (a mixture of ethoxylated fatty amine and oil) to a wettable powder containing compound A and pyridate as the herbicidal active ingredient superior to the herbicidal activity of the composition obtained by adding to the wettable powder only Frigate (ethoxylated fatty amine).

Example 15 biological tests
Blood Rosichka seeds (Digitaria sanguinalis L.) were sown in pots with an area of 1/1000000 ha, filled with soil from the upper layer and located in a double system. When the blood dewdrop plants grew to a 3.8 leaf stage, the oil-based suspension concentrate obtained in Example 12 (an oil-based suspension concentrate containing compound A and bromoxynil [commonly used name] as the herbicidal active ingredient) was diluted with water (200 l / ha) containing 0.2% vol. Frigate (trade name), and applied to the leaves of plants using a small spray.

 25 days after treatment, the inhibition of plant growth was evaluated by visual observation in the same manner as in example 1 biological tests; the results are shown in table 15.

 As can be seen from the results shown in Table 15, when Frigate (ethoxylated fatty amine) was added to an oil-based suspension concentrate containing compound A and bromoxynil as the herbicidal active ingredient, due to the fact that the “herbicidal ingredients, ethoxylated fatty amine and oil ", which are the subject of the present invention, are present in the resulting composition, the activity exceeds the activity of the composition obtained by the removal of Frigate (ethoxylated fatty amine) from the composition.

Example 16 biological tests
Seeds of blood dewdrops - DS (Digitaria sanguinalis L.), Indian Elevinsines - EI (Eleusine indica L.), Theophrastus AT (Abutilon theophrasti MEDIC.), Common Gooseberry - XS (Xanthium strumarium L.) and Wormwood - AA ( Ambrosia artemisiifolia L.) were sown on the upland plots of the field and test plots were set up according to the pair system. When the development of plants reached a certain stage in the development of leaves (blood dewdrop: stages 3.3; Indian elevzina: stages 3.3; rosacea Theophrastus: stages 2.0; common gorse: stages 2.3 and ragweed: leaves 2.0 stages ), an oil suspension concentrate containing compound A as a herbicidal active ingredient and an aqueous suspension concentrate containing atrazine (a common name) as a herbicidal active ingredient was diluted with water (300 l / ha) containing 0.25 vol. % Frigate (trade name), and applied to the leaves of plants using a spray.

 Four weeks after treatment, the inhibition of plant growth was evaluated by visual observation in the same manner as in example 1 biological tests. The results are shown in table 16.

 As is evident from the results shown in table 16, when Frigate (ethoxylated fatty amine) is added to an oil suspension concentrate containing compound A as a herbicidal active ingredient, and an aqueous suspension concentrate containing atrazine as a herbicidal active ingredient (common name) due to the fact that in the resulting composition there are "herbicidal ingredients, ethoxylated fatty amine and oil", which are the subject of the present invention, its effectiveness is superior t is the effectiveness of the composition obtained by removing Frigate (ethoxylated fatty amine) from the composition.

[Comparative example 1 biological tests]
[Test Method 1]
The test was carried out according to example 1 biological tests described in the description of this application with the exception of the following.

 Test scale: 1/1000000 ha pot, dual system.

 Test weeds: blood dewdrop (Digitaria sanguinalis L.) in stage 3.1 of the leaf.

 Test herbicide: a herbicide containing flazasulfuron (commonly used name) as the active ingredient.

 Amount of herbicide used: flazasulfuron 6.25 g / ha.

 Study day: 14 days after treatment.

[Test Method 2]
The test was carried out according to example 1 biological tests described in the description of this application, with the exception of the following.

 Test scale: 1/1000000 ha pot, dual system.

 Test weeds: blood dewdrop (Digitaria sanguinalis L.) in the stage from 2.5 to 3.0 leaves.

 Test herbicide: a herbicide containing nicosulfuron (commonly used name) (compound A in the description of this application) as an active ingredient.

 Amount of herbicide used: Nicosulfuron 5 g / ha.

 Study day: 24 days after treatment.

 The test results are shown in table 17.

 This comparative example 1 biological test is based on the test results of nicosulfuron, which is a herbicidal active ingredient such as sulfonylurea, i.e. the ingredient described in this application (compound A) and flazasulfuron tests, both tests being carried out almost simultaneously. The above-described flasasulfuron {N - [[(4,6-dimethoxy-2-pyrimidinyl) amino] carbonyl] -3- (trifluoromethyl) -2-pyridinesulfonamide} is a compound of the same type (having a chemical structure with the same basic skeleton) as a herbicidal active ingredient such as sulfonylurea, which is described in this application; more specifically, compound A — nicosulfuron and compound B — primisulfuronmethyl (commonly used name).

 From this comparative example 1 biological tests, you can see the following. When Frigate (ethoxylated fatty amine) and oil were each used individually as an additive to flazasulfuron, which is a herbicidal active ingredient such as sulfonylurea, a fixed herbicidal activity could be observed. At the same time, even if they were used together in accordance with the present invention, the herbicidal activity was almost the same as in the case of using only Frigate. (European patent 257686 suggests that the herbicidal activity of sulfonylurea is enhanced by the combined use of ethoxylated fatty amine and oil. If this assumption applies to all sulfonylureas, the herbicidal activity of flazasulfuron should also increase, but in reality there is no such increase in activity). In contrast, nicosulfuron, although it is a compound of the same type as flazasulfuron, shows a much higher herbicidal activity (synergistic) when Frigate and oil are used together than the activity obtained when used separately.

[Comparative example 2 biological tests]
[Test Method]
The tests were carried out in accordance with example 1 of the biological tests described in the description of the present application, with the exception of the following.

 Scale of tests: a pot with an area of 1/1000000 ha, a dual system.

 Test weeds: blood dewdrop (Digitaria sanguinalis L.) in the stage of 3.5-4.0 leaves.

 Test herbicide: a herbicide containing glyphosatisopropylammonium (commonly used name) as the active ingredient (trade name Roundup).

 Amount of herbicide used: glyphosatisopropylammonium 62.5 g / ha.

 Amount of sprayed water: 500 l / ha.

 Study day: 21 days after treatment.

 The test results are shown in table 18.

 From this comparative example 2 biological tests, you can see the following. If the case where an emulsifier (Frigate is a surfactant of the ethoxylated fatty amine type described in Polish patent 146446) and an oil component (not specifically defined mineral oil described in Polish patent 146446) are each used individually as an additive to glyphosatisopropylammonium (commonly used name) , which is a type of pesticide, is compared with the case when they are used together (which corresponds to the agent mentioned in Polish patent 146446) according to Polish patent 146446, then when they are used together olzovanii there is a marked herbicidal activity. However, in this comparative example 2 biological tests, the exact opposite effect was obtained. That is, the use of an emulsifier and oil together leads to a decrease in herbicidal activity.
