Abstract

PROBLEM TO BE SOLVED: To provide a herbicide composition that is highly safe for cultivation plants, and can effectively control a wider range of weeds at a lower dosage by a synergistic effect of active ingredients, a use method and a weed controlling method.SOLUTION: A herbicide composition contains, as an active ingredient, three herbicides combining: carfentrazone or carfentrazone-ethyl; at least one compound selected from photosynthesis inhibitors; and at least one compound selected from VLCFA (very-long-chain fatty acid) synthesis inhibitors that exhibit effect in soil treatment. There are also provided a method for use of the herbicide composition and a weed controlling method.

Description

The present invention relates to one or more compounds selected from carfentrazone or carfentrazone-ethyl and a photosynthesis (photosystem II) inhibitor, and one or more 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 by mixing three kinds of herbicides in combination with the above compound, a method for using the herbicide composition, and a method for controlling weeds.

  Carfentrazone or carfentrazone-ethyl which is a PPO (protoporphyrinogen oxidase) inhibitor (hereinafter referred to as “PPO inhibitor”) is a known herbicide used in and outside Japan (non-patent document) 1), it is known that the effect is exhibited by soil treatment or foliage treatment before / after germination of weeds. This medicine has a low control effect on grass weeds and needs to be mixed with other herbicides, but when used with other herbicides, there are cases where herbicidal activity is reduced due to antagonism, and the combined use is limited. (See Patent Document 1 and 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 in order to solve the above-mentioned problems. Excellent by mixing three kinds of herbicides as active ingredients in combination with one or more compounds selected from inhibitors and one or more compounds selected from VLCFA synthesis inhibitors that are effective in soil treatment We found that a synergistic effect was seen. 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.

  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).

As each drug, a preparation according to the preparation example or a commercially available product in Japan and abroad was used. Carfentrazone or carfentrazone-ethyl single agent is commercially available carfentrazone: Emulsion ELEVATE ® 400EC, Carfentrazone 240EC, Granule wettable powder ARTILLERY ® 400WG, EW Unity ® 240EW (in the table, "Carfentrazone" Carfentrazone-ethyl: wettable powder Nissan Hardy DF, granule wettable powder Affinity 400 DF, emulsion NAIL 240EC Herbicide (shown as “Carfentrazone-ethyl” in the table) and the like were used. In addition, the 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 as “Atrazine” in the table), etc. Emulsion Harness (indicated as “Acetochlor” in the table), etc., S-metolachlor single agent as a commercially available emulsion sibatch emulsion (indicated in the table as “S-Metolachlor”), etc., and dimethenamide-P As a single agent, a commercially available emulsion field star emulsion (denoted as “Dimethenamid-P” in the table) or the like was used.

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 27 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 carfentrazone-ethyl, acetochlor, or atrazine was treated with a single agent, the dose used in the test did not show a sufficient effect on rat wheat, and 2 Even with the seed combination treatment, sufficient effect was not obtained as compared with the expected value (E1), but the expected value (E2) was obtained by treating the carfentrazone-ethyl, acetochlor, and atrazine together. A much higher synergistic effect was observed, indicating an excellent herbicidal effect.

As is apparent from Table 2, when carfentrazone-ethyl, S-metolachlor, or atrazine was treated with a single agent, the dose used in the test did not show a sufficient effect on rat. Even when the two treatments were combined, the effect was not sufficient compared to the expected value (E1). A synergistic effect far exceeding that of (E2) was observed, indicating an excellent herbicidal effect.

As is apparent from Table 3, when carfentrazone-ethyl, 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, Even when the treatment with the two kinds was combined, the sufficient effect was not obtained as compared with the expected value (E1). However, the expected value ( A synergistic effect far exceeding that of E2) was observed, indicating an excellent herbicidal effect.

Test Example 2 Field for Spodoptera (Poa annua) Soil treatment test A resin pot with an area of 63.5 cm ² was filled with a pelagic sandy loam soil and uniformly seeded with Suzumata Katabira seeds and uniformly covered with soil. 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 27 days after the treatment, and the expected value was calculated according to Equation 1 and Equation 2. The results are shown in Table 2. In the table, DAA represents the number of days after processing, and E represents the expected value.

As is clear from Table 4, when carfentrazone-ethyl, acetochlor, or atrazine was treated with a single agent, the dose used in the test did not show a sufficient effect on the spider grass, Even when the two kinds of treatments were combined, a sufficient effect was not obtained as compared with the expected value (E1). A synergistic effect far exceeding the above was recognized, and an excellent herbicidal effect was exhibited.

  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.
