Adjusted the amount of. After sowing seeds of barnyard grass, leptochloa vulgaris and Cyperus iria on alluvial soil, Wagner pots were placed in a greenhouse at 25 ° C to 30 ° C to grow plants. After growing for 14 days, the emulsion of the compound of the present invention prepared according to Formulation Example 2 was diluted with water so as to have a predetermined dosage, and the foliage was uniformly treated with a small spray. Two weeks after the drug treatment, the effects on various plants were investigated according to the following criteria. The results are shown in Table 1. Judgment Criteria 5: Weed killing rate 90% or more (almost complete death)
4 ... Weeding rate 70% or more and less than 90% 3 ... Weeding rate 40% or more and less than 70% 2 ... Weeding rate 20% or more and less than 40% 1 ... Weeding rate 5% or more and less than 20% 0.・ ・ Weed killing rate 5% or less (almost no effect)
In Table 1, for example, the notation "A1 + tetflupyrrolimet" in the "Compound No." column represents the composition of compound A1 and tetflupyrrolimet, and "treated dose (g / ha)". The notation "100 + 100" in the column indicates that 100 g / ha of compound A1 and 100 g / ha of tetflupyrrolimet are mixed. The amount of treated drug (g / ha) ha represents hectare (10000 m ² ).
In the table, the notation "a" represents barnyard grass, "b" represents Leptochloa vulgaris, and "c" represents Cyperus iria. The herbicidal effect for each is described according to the above criteria.

[Test Example 2] Test of herbicidal effect by weed growing season treatment under flooded conditions After putting alluvial soil in a Wagner pot of 1/10000 ares, water was added and mixed to obtain a flooded condition with a water depth of 4 cm. Seeds of Tainubier, Inuhotarui and Pontederia vaginalis were mixedly sown in the above pots and placed in a greenhouse at 25 to 30 ° C. to grow plants. When Tainubier reached the two-leaf stage, the emulsion of the compound of the present invention prepared according to Formulation Example 2 was diluted with water to a predetermined dosage and treated on the surface of the water. Two weeks after the drug treatment, the effect on various plants was investigated according to the criteria of Test Example 1. The results are shown in Table 2.
Regarding the contents described in Table 2, the description in the "Compound" column and the "Treatment amount (g / ha)" column has the same meaning as described above.
In the table, the notation "d" represents Tainubier, and similarly, "e" represents Inuhotarui and "f" represents Pontederia vaginalis.
