Abstract

Herbicides are used for the purpose of weed control in the cultivation of useful crops such as wheat and barley, rice, corn, pulses, potato, cotton, rape seed, sunflower, fruit trees, fruits, and grasses. However, due to the weather, the temperature, the soil of a useful crop cultivation area, the application method when applying the herbicide and the like, the controlling effect may be insufficient. As a result, the yield of the cultivated useful crop decreases, and therefore there is a strong demand for increasing the strength of the controlling effect. Provided is a herbicidal composition and a method for use thereof, said composition comprising: pyraflufen-ethyl or an agriculturally acceptable salt thereof as a first active ingredient; and at least one compound selected from the group consisting of carfentrazone-ethyl, sulfentrazone, flumioxazin, fomesafen, acifluorfen, oxyfluorfen, fluthiacet-methyl, butafenacil, saflufenacil, lactofen, and agriculturally acceptable salts of said compounds as a second active ingredient.

Description

In the cultivation of useful crops such as wheat, soybeans, kidney beans, green soybeans and corn, the herbicides are used for the purpose of controlling weeds. However, there are cases where the herbicidal effect is insufficient depending on the weather, temperature, spraying method, etc. of the crops where the useful crop is cultivated. Moreover, with respect to difficult-to-control weeds and drug-resistant weeds, conventional herbicides may have a low herbicidal effect. Therefore, under the present circumstances, in order to ensure a desired weed control effect, the countermeasure of spraying an excess herbicide is often taken.

However, it is not preferable to spray an excessive amount of herbicide because there is a great labor and economic burden on the user and there are problems such as environmental pollution.
Therefore, enhancement of the herbicidal effect of the herbicide used in cultivation of useful crops is strongly desired so that more effective weed control is possible.

In view of the above situation, an object of the present invention is to provide a herbicidal composition that exhibits a herbicidal effect more efficiently in controlling weeds when cultivating useful crops, and more specifically, conventionally used. It is to provide a herbicidal composition that exhibits a herbicidal effect sufficiently by use of a dosage smaller than the dosage.

In order to solve the above-mentioned problems, the present inventor has eagerly searched for a novel herbicidal composition, and uses two or more kinds of compounds selected from protoporphyrinogen oxidase-inhibiting herbicides. Thus, a synergistic effect was observed, and it was found that a sufficient herbicidal effect was manifested with a treatment dose smaller than the respective standard doses, and further studies were made to complete the present invention.

Next, test examples of the composition of the present invention will be shown. In the following test examples, the “expected value” is the activity expected by a specific combination of two herbicides, and can be calculated from the following Colby equation. (See Colby, S.R., Weeds 15: 20-22 (1967) IV.)

Here, E is the herbicidal effect expected when herbicide A is mixed with pga.i./ha and herbicide B is qga.i./ha, and X is herbicide A alone. Inhibition rate (herbicidal effect) when treated with ./ha, Y indicates the inhibitory rate (herbicidal effect) when only herbicide B is treated with qga.i./ha. If the herbicidal effect when actually mixed with two herbicides exceeds this E value, the combination can be said to exhibit a synergistic effect. The above "ga.i./ha" means the amount of herbicide treated per hectare (g).
The herbicidal effect was determined according to the following formula.

Test Example 1 Test of control effect against sagebrush of sagebrush A resin pot having a treatment test area of 110 cm ² was filled with a plowing soil and uniformly seeded with a sagebrush of sagebrush. Thereafter, the cultivation management was continued outdoors, and when the growth weeds of the test weed reached 18-28 leaves and the plant height reached 21 cm, a commercially available pyraflufenethyl 2.5% emulsion and fomesafen 40% solution, flumioxazin 50 % Granule wettable powder, saflufenacil 29.74% flowable agent, and carfentrazone ethyl 21.33% of the drug selected from the emulsion preparation is mixed with a predetermined effective dosage (g as an active ingredient) / Ha) as a chemical solution. Then, the plants were grown outdoors, and the ground weight of each weed was measured 76 days after the treatment, and the herbicidal effect and expected value were determined by the above formula. Similarly, the herbicidal effect of each drug alone was also evaluated. The results are shown in Tables 1 to 4.

Test Example 2 Control Effect Test on Greater Blue Spider A resin pot having a treatment test area of 110 cm ² was filled with a plowing soil and uniformly seeded with the seed of the giant red spider. After that, the cultivation management was continued in the glass greenhouse. When the growing weeds of the test weeds reached 5-6 leaves and the plant height reached 12 cm, a commercially available pyraflufenethyl 2.5% emulsion was mixed with a fomesafen 40% solution. And it processed as a chemical | medical solution of predetermined effective dose (g / ha as an active ingredient). Subsequently, it was grown in a glass greenhouse, and after 4 days of treatment, the above-ground living weight of each weed was measured, and the herbicidal effect and the expected value were obtained by the above formula. Similarly, the herbicidal effect of the drug alone was also evaluated. The results are shown in Table 5.

From the test results in Tables 1 to 5, it can be seen that the herbicidal effect when using two drugs in combination exceeds the expected value obtained from the Colby equation, compared to when using them alone, A synergistic effect is observed.
That is, it was shown that even when the treatment with pyraflufen-ethyl and other protoporphyrinogen oxidase-inhibiting herbicides alone is insufficient, the control effect is remarkably improved when mixed.

The herbicidal composition of the present invention exhibits a sufficient herbicidal effect with a dose smaller than that conventionally used alone. Therefore, according to the herbicidal composition of the present invention, the amount of herbicide used can be reduced, and the environmental load caused by the drug and the labor and economic burden of the user can be reduced.
Moreover, since the herbicidal composition of the present invention has a high herbicidal effect that could not be achieved by using a conventional herbicide alone, it is possible to control weeds that could not be controlled by the use of a conventional herbicide alone. More specifically, according to the present invention, weeds that cannot be controlled with pyraflufenethyl or other protoporphyrinogen oxidase-inhibiting herbicides alone can be controlled.
