Effect of the Invention

The herbicidal composition of the present invention can be used safely for controlling weeds in the cultivation of agricultural and horticultural crops. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The herbicidal composition of the present invention (hereinafter, for the sake of simplicity, may be referred to as the "composition of the present invention") contains compound (I) and compound (II).

[0016] [Compound (I)] Compound (I) is at least one compound selected from the compounds represented by formula (I) or a salt thereof.

[0017] [ka]

[0018] Compound (I) also includes hydrates, various solvates, and crystal polymorphs. Compound (I) may have stereoisomers based on asymmetric carbons, double bonds, and the like, and tautomers. Such isomers and mixtures thereof are included in compound (I). Examples of salts of the compound represented by formula (I) include salts of alkali metals such as lithium, sodium, and potassium; salts of alkaline earth metals such as calcium and magnesium; salts of transition metals such as iron and copper; ammonium salts; salts of organic bases such as triethylamine, tributylamine, pyridine, and hydrazine; and the like. The structure of compound (I) can be determined by NMR spectrum, IR spectrum, MS spectrum, and the like.

[0019] The term "unsubstituted" as used herein means that only the group that serves as the mother nucleus is present. When there is no description of "substituted" and only the name of the group that serves as the mother nucleus is described, it means "unsubstituted" unless otherwise specified. On the other hand, the term "substituted" means that any hydrogen atom of the core group is replaced with a group (substituent) having the same or different structure as the core group. Thus, a "substituent" is another group bonded to the core group. The number of substituents may be one or more. The two or more substituents may be the same or different. Terms such as "C1-6" indicate that the number of carbon atoms in the parent group is 1 to 6. This number of carbon atoms does not include the number of carbon atoms in the substituents. For example, a butyl group having an ethoxy group as a substituent is classified as a C2 alkoxy C4 alkyl group.

[0251] (3) Evaluation The herbicidal effect was evaluated visually 6 days after treatment, comparing the condition with the untreated area and rating it as herbicidal effect (%) using a mortality index of 0 to 20 (0: mortality rate equivalent to the untreated area, 20: mortality rate of 100%). In addition, the expected value of the herbicidal effect was calculated from the herbicidal effect in the case of applying compound (I) alone and the herbicidal effect in the case of applying compound (II) alone using Colby's formula (S.R.Colby, Calculating synergistic and antagonistic responses of herbicide combinations, Weeds, 15, 20-22pp(1967)). The expected value calculated by Colby's formula represents the herbicidal effect of the compound (I) test plot and the additive effect of the compound (II) test plot. E = M + N - (M × N / 100) M indicates the herbicidal effect (%) when compound (I) is applied alone, N indicates the herbicidal effect (%) when compound (II) is applied alone, and E indicates the expected value (%) of the herbicidal effect when compound (I) and compound (II) are applied in combination. When the actual value (%) of the herbicidal effect when compound (I) and compound (II) are applied in combination is greater than the expected value E, the combined application of compound (I) and compound (II) has a synergistic effect. The actual and expected values ​​of the herbicidal effect are shown in Table 1.

The active ingredient (4 mg) of the composition of the present invention was dissolved in this emulsion (100 μL) to prepare a test emulsion. POA means "polyoxyalkylene", POE means "polyoxyethylene", and POP means "polyoxypropylene". As compound (I), 1-methoxy-3-methyl-6-(1,1-dioxido-8-(trifluoromethyl)thiochroman-5-yl)-7-oxa-3,4-diazabicyclo[4.1.0]hept-4-en-2-one (compound (I-3)) was used. Acetochlor or Atrazine was used as compound (II). (2) Foliage spray treatment 300cm 2 The pots were filled with soil, and seeds of Zea mays, Setaria faberi, Sorghum halepense, Brachiaria platyphylla, Amaranthus palmeri, Senna obtusifolia, and Ipomoea hederacea were sown on the surface, lightly covered with soil, and grown in a greenhouse. When the plants reached a height of 7-11 cm, they were used in the test. The test emulsion was diluted to the prescribed amount of active ingredient, and sprayed on the foliage with a small sprayer at a spray volume of 250 L per hectare. (3) Evaluation The herbicidal effect was evaluated by measuring the aboveground fresh weight of each weed in the untreated and treated plots three weeks after application, and calculating the herbicidal effect (%) using the following formula. In addition, the expected value of the herbicidal effect was calculated from the herbicidal effect in the case of applying compound (I) alone and the herbicidal effect in the case of applying compound (II) alone using Colby's formula (S.R.Colby, Calculating synergistic and antagonistic responses of herbicide combinations, Weeds, 15, 20-22pp(1967)). The expected value calculated by Colby's formula represents the herbicidal effect of the compound (I) test plot and the additive effect of the compound (II) test plot. E = M + N - (M × N / 100) M indicates the herbicidal effect (%) when compound (I) is applied alone, N indicates the herbicidal effect (%) when compound (II) is applied alone, and E indicates the expected value (%) of the herbicidal effect when compound (I) and compound (II) are applied in combination. When the actual value (%) of the herbicidal effect when compound (I) and compound (II) are applied in combination is greater than the expected value E, the combined application of compound (I) and compound (II) has a synergistic effect. The actual and expected values ​​of the herbicidal effect are shown in Table 4. (4) Calculation formula for herbicidal effect Herbicidal effect (%) = (above-ground fresh weight of untreated area - above-ground fresh weight of treated area) / (above-ground fresh weight of untreated area) x 100
