The present invention relates to a novel herbicide composition.
Compounds represented by the later-shown formula [I] which are each the “component A” of the herbicide composition of the present invention, are known compounds described in Patent Literature 1, Patent Literature 4 and Patent Literature 5, which are safe to rice, wheat, barley, corn, grain sorghum, soybean, cotton, sugar beet, turf grass, fruit trees, etc. and which have excellent herbicidal effects by themselves.
Later-shown compounds which are each the “component B” or the “component C” used in the herbicide composition of the present invention, are known compounds having herbicidal activities and are described in, for example, Non-Patent Literatures 1 to 3.
Later-shown compounds described as “component D” are compounds each known as a safener and are described in Non-Patent Literatures 1 and 2.
In the Patent Literature 2 and the Patent Literature 3 are described application examples in which a compound represented by the formula [I] can be mixed with known herbicide compounds.
The present invention aims at providing a herbicide composition containing an isoxazoline derivative represented by the later-shown formula [I] or a salt thereof, in order to control weeds which are undesirable in the cultivation of useful crops or useful plants.
The present inventors made a study in order to achieve the above aim. As a result, the present inventors found that when the “component A” which is an isoxazoline derivative represented by the later-shown formula [I] or a salt thereof, is mixed with a herbicide shown in the later-shown “component B”, or with the “component B” and a herbicide shown in the later-shown “component C”, or with the “component B” and a safener shown in the later-shown “component D”, or with the “component B”, the “component C” and the “component D”, the herbicidal effect obtained is not only the simple sum of the herbicidal effects of the individual components but also the synergism of the herbicidal effects of the individual components, or a lower phytotoxicity appears owing to the synergism.
That is, the present inventors found that, when two or more kinds of pesticides are used, as compared with the herbicidal range when each one of the pesticides is used independently, the herbicidal spectrum becomes wider, at the same time the herbicidal effect is achieved earlier; the effect lasts longer, and a sufficient effect is obtained at a smaller total dosage as compared with the same when each one of the pesticides is used independently; and that the safety to rice, wheat, barley, corn, grain sorghum, soybean, cotton, sugar beet, turf, fruit trees, etc. is secured and a sufficient herbicidal effect is obtained by one-time treatment. The finding has led to the completion of the present invention.

A paddy soil was filled in a plastic pot of 100 cm2 and subjected to puddling. Thereinto were sowed seeds of Echinochloa oryzicola Vasing, Monochoria vaginalis (Burm. f.) Kunth, or Schoenoplectus juncoides (Roxb.) Palla, after which water was filled at a depth of 3 cm. Each pot was placed in a greenhouse for raising. At a timing when the Echinochloa oryzicola Vasing reached about a two-leaf stage, a seedling of two-leaf stage rice (variety: Kinnanpuu) was transplanted into each pot at a depth of 2 cm. A wettable powder prepared in accordance with Formulation Example 2 was diluted with water based on the total sum of the active ingredients, and the dilution was dropped on the water surface of the pot. Then, the pot was allowed to stand for raising. The herbicidal effect of the wettable powder was examined at the 28th day of the treatment (the dropping of the dilution) in accordance with the standard of Table 4. The results are shown in Table 5.
