The present invention is a combination of one or more compounds selected from flumioxazin and a photosynthesis (photosystem II) inhibitor, and one or more compounds selected from a VLCFA (very long chain fatty acid) synthesis inhibitor. The present invention relates to a composition having a broad herbicidal spectrum synergistically with respect to various weeds, a method for using the herbicidal composition, and a method for controlling weeds.

  Flumioxazin, which is a PPO (protoporphyrinogen oxidase) inhibitor (hereinafter referred to as “PPO inhibitor”), is a known herbicide used in Japan and overseas (see Non-Patent Document 1). The effect is demonstrated by soil treatment or foliage treatment after germination, but it is known to be inferior to Gramineae and perennial weeds (see Non-Patent Document 2). Amethrin, atrazine, cyanazine, desmethrin, dimetamethrin, promethone, promethrin, propazine, CAT (simazine), cimetrin, terbumethone, terbutyrazine, terbutrin and trietadine are also photosynthesis (photosystem II) inhibitors (hereinafter referred to as “photosynthesis inhibitors”). Moreover, it is a well-known herbicide used domestically and internationally (refer nonpatent literature 1), and it is known that an effect will be exhibited mainly by soil treatment before germination of a broad-leaf weed. The chloroacetamide compounds acetochlor, alachlor, butachlor, dimethachlor, dimethenamide, dimethenamide-P, metazachlor, metolachlor, S-, which are VLCFA (very long chain fatty acid) synthesis inhibitors (hereinafter referred to as "VLCFA synthesis inhibitors") Metrachlor, petoxamide, pretilachlor, propachlor, propisochlor and tenyl chlor are also known herbicides used domestically and internationally (see Non-Patent Document 1), and weeds, particularly grass weeds (monocotyledonous weeds). In the following, it is known that the effect is exhibited by treating the soil before germination).

However, since weeds that cannot be controlled by using these active ingredients alone remain, the herbicide treatment is often required again for the residual grass treatment. Even with the combined use / mixture of multiple herbicides, it is difficult to control many types of weeds at once. Therefore, creation of a herbicidal composition that is highly safe for cultivated plants and that can effectively control more types of weeds and the like with a lower dose is desired. Gramineous weeds and broadleaf weeds often differ greatly in herbicide sensitivity, and it is difficult to control these weeds at the same time, especially with herbicides with crop selectivity. In addition, various weeds having resistance to herbicides have become a problem in recent years, and a herbicidal composition and a weed control method that can simultaneously control such herbicide-resistant weeds are required.

The present inventor has eagerly searched for a novel herbicidal composition to solve the above problems, and surprisingly, one or more selected from flumioxazin known as a PPO inhibitor and a photosynthetic inhibitor. It has been found that an excellent synergistic effect can be seen by mixing as an active ingredient three kinds of herbicides, which are a combination of one or more compounds selected from VLCFA synthesis inhibitors that exhibit an effect in soil treatment. It was. It has been found that a high herbicidal effect is manifested against many types of weeds, particularly the grass family of the genus Gramaceae and the family Gramineae, and safe for cultivated plants, with a treatment dose lower than the standard dose. The present invention has been completed.

Similarly, SR corn and the like are examples of crops to which tolerance has been imparted to acetyl CoA carboxylase inhibitors such as trione oxime and aryloxyphenoxypropionic acid herbicides by classical breeding methods.

  A crop imparted with tolerance to an ACCase (acetyl-CoA carboxylase) inhibitor is Proc. Natl. Acad. Sci. USA 87, 7175-7179 (1990). In addition, mutant acetyl CoA carboxylase resistant to ACCase (acetyl CoA carboxylase) inhibitors has been reported in Weed Science 53, 728-746 (2005). A crop resistant to an ACCase (acetyl CoA carboxylase) inhibitor can be produced by introducing a mutation associated with imparting resistance into a crop acetyl CoA carboxylase. Furthermore, a base substitution mutation-introduced nucleic acid typified by chimera plastic technology (Gura T. 1999. Repairing the Genome's Spelling Mistakes. Science 285: 316-318.) Is introduced into plant cells to produce an acetyl CoA carboxylase of the crop. By introducing site-specific amino acid substitution mutations into genes, ALS genes, etc., crops resistant to ACCase (acetyl CoA carboxylase) inhibitors, ALS (acetolactic acid synthase) inhibitors and the like can be produced.

  Examples of crops that have been given herbicide tolerance by genetic engineering techniques include glyphosate-resistant maize, soybean, cotton, rapeseed, and sugar beet varieties, such as Roundup Ready (registered trademark) and AgrisureGT Already sold by name. Similarly, there are corn, soybean, cotton, and rapeseed varieties that are resistant to glufosinate by gene recombination technology, and are already sold under trade names such as Liberty Link (registered trademark).

  Next, test examples of the composition of the present invention will be shown. In the following test examples, by using (A), (B), and (C) in combination, an effect (synergistic effect) exceeding the effect expected from the effect when each was used alone was shown. . A synergistic effect is an effect when two or more drugs act simultaneously, and the effect is greater than expected from the activity of each alone.

The activity expected by a specific combination of two herbicides (referred to as “expected value”) is the following Colby formula (see Colby, SR, Weeds, 15, p. 20-22 (1967)): Can be calculated from
[Equation 1]
E1 = (α + β) − (αβ) / 100
However, in the formula,
α = herbicidal effect when herbicide X is treated in an amount of xg / ha,
β = herbicidal effect when herbicide Y is treated with good gg / ha,
E1 = herbicidal effect expected when herbicide X is treated with xg / ha and herbicide Y is treated with yg / ha.

The combination of the three active ingredients can be similarly calculated as follows.
[Equation 2]
E2 = (α + β + γ) − (αβ + αγ + βγ) / 100 + (αβγ) / 10000
However, in the formula,
α = herbicidal effect when herbicide X is treated in an amount of xg / ha,
β = herbicidal effect when herbicide Y is treated in an amount of yg / ha,
γ = herbicidal effect when herbicide Z is treated in the amount of zg / ha
E2 = Herbicidal effect expected when herbicide X is treated with xg / ha, herbicide Y with yg / ha and herbicide Z with zg / ha.

That is, it can be said that when the actual herbicidal effect (actually measured value) is larger than the herbicidal effect (calculated value) by the above calculation, the activity by the combination shows a synergistic action.
The herbicidal composition of the present invention exhibits a synergistic effect when calculated by the above formula.

The herbicidal effect in the pot test was evaluated according to the following criteria in comparison with the untreated group.
As a criterion for herbicidal effect, the degree of herbicidal effect was evaluated from 0% (no effect) to 100% (complete withering).

For each drug, a formulation according to the formulation example was used, or a commercially available product in Japan and abroad was used. The single agent of flumioxazin is the commercially available flumioxazin: granule GANGSTER &#8482; V, granule wettable powder Valor &reg; SX, granule wettable powder Payload &reg; Herbicide (indicated in the table as "flumioxazin"), etc. A single agent of atrazine is a preparation according to the formulation example or a commercially available flowable preparation, such as Gezaprim Flowable (SC) or wettable powder Atrazina (indicated in the table as “Atrazine”), etc., and a single agent of acetochlor is a commercially available emulsion. Harness (indicated as “Acetochlor” in the table), etc., dimethenamide as a single agent is a commercially available emulsion field star emulsion (indicated as “dimethenamid-P” in the table), etc., and S-metolachlor as a single agent Commercially available emulsion sibatch emulsion (in the table, indicated as “S-metolachlor”) or the like was used. Evaluation of mixed use of flumioxazin, atrazine and acetochlor, flumioxazin, atrazine and dimethenamide-P, and flumioxazin, atrazine and S-metolachlor were carried out using a mixture of commercially available single agents.

Test Example 1 Field for soil wheat (Italian ryegrass) Soil treatment test A resin pot with an area of 63.5 cm ² was filled with a sandy sandy loam soil, and seeds of wheat ryegrass were uniformly sown and covered uniformly. On the day after sowing, each herbicide diluted or diluted / mixed to a predetermined concentration was uniformly sprayed on the soil. As a single agent of each active ingredient, a commercially available agent or a preparation according to a preparation example was used. Further, they were mixed to prepare a mixed treatment chemical solution.

  The pot after the herbicide treatment continued cultivation management outdoors, the herbicidal effect was evaluated 22 days after the treatment, and the expected value was calculated according to Equation 1 and Equation 2. The results are shown in Table 1. In the table, DAA represents the number of days after processing, and E1 and E2 represent the expected values at the time of 2 mixing and 3 mixing, respectively. (The following table is the same.)

As is apparent from Table 1, when flumioxazin, acetochlor, or atrazine was treated with a single agent, the dose used in the test did not show a sufficient effect on murine wheat, and even with the combined treatment of two species Although a sufficient effect was not obtained compared with the expected value (E1), a synergistic effect exceeding the expected value (E2) was recognized by the combined treatment of flumioxazin, acetochlor and atrazine, and excellent Showed herbicidal effect.

As is clear from Table 2, when flumioxazin, S-metolachlor, or atrazine was treated with a single agent, the doses used in the test did not show sufficient effects on rat wheat, and the two were used in combination. In the treatment, sufficient effect was not obtained as compared with the expected value (E1), but the synergistic effect exceeding the expected value (E2) was obtained by the combined treatment of flumioxazin, S-metolachlor and atrazine. It was recognized and showed an excellent herbicidal effect.

As is apparent from Table 3, when flumioxazin, dimethenamide-P, or atrazine was treated with a single agent, the dose used in the test did not show a sufficient effect on murine wheat, and the combination treatment of two species However, although sufficient effect was not obtained compared with the expected value (E1), a synergistic effect exceeding the expected value (E2) was recognized by the combined treatment of flumioxazin, S-metolachlor and atrazine. And showed an excellent herbicidal effect.

  The herbicidal composition of the present invention has a broad herbicidal spectrum with respect to various weeds compared to single agent application, and exhibits an excellent control effect at a low dosage, thus reducing the number of herbicide application times, etc. This is useful because it has less impact on the global environment.
