０６５号）。また別の除草剤として。Herbicides for paddy fields in Japan are roughly divided into three categories, early, middle, and late herbicides, based on the timing of use, and the reality is that they are used in systematic treatment by combining these herbicides. Conventionally, substituted phenoxyureas represented by the following general formula CI) Q (where n represents an integer of 0 to 2 and 1m represents an integer of 4 to 6) are used as herbicides. (hereinafter referred to as compound (A)) is known as an active ingredient (JP-A-61-126
No. 065). Also as another herbicide.

かも使用適期幅が長く、水稲に安全な除草剤の出現が強
く望まれている。In recent years, for the purpose of saving agricultural work and preserving the environment, the absolute amount of herbicides sprayed on rice fields has been reduced, making it possible to control all weeds, including perennial weeds, with a single treatment, and to reduce the appropriate application period. There is a strong desire for a herbicide that is safe for paddy rice to emerge.

という問題点がある。そのため前記化合物（Ａ）、（Ｂ
）をそれぞれ単独で使用した場合の除草活性は常に充分
満足できるものではない。However, although the compound (A) has a remarkable effect on wild grasses, annual broad-leaved weeds, firefly, etc., it has a problem in that it is less effective against perennial weeds such as lilycystis vulgare, omodaka, and water hyacinth. In addition, compound (B) has a remarkable effect on perennials such as Prunus japonicus, Omodaka, and Cyperus spp., but there is a problem in that it shows almost no effect on Novie, a weed of the grass family. Therefore, the compounds (A), (B
) are not always fully satisfactory in herbicidal activity when used alone.

組成物を提供することを目的としている。The present invention is intended to solve the above problems, and by using the above compound (A) and compound (B) in combination, a synergistic effect can be obtained, and this can be achieved at any time from the beginning of weed emergence to the growing season. The object of the present invention is to provide a herbicidal composition that can be used, has an accurate herbicidal effect on a wide range of weeds, and is safe for action.

除草剤組成物である。The herbicide composition of the present invention complements and exhibits a complete control effect on weeds that are difficult to control with a single agent, and also exhibits a synergistic herbicide effect even at low doses that cannot completely control weeds. It exerts a remarkable control effect not only on weeds but also on perennial weeds, which have been occurring frequently in recent years, over a long period of time, from the weed onset period immediately after rice planting to the growing season. For example, the growth period of annual and perennial weeds, such as Japanese grasshopper, Japanese grasshopper, and other annual broad-leaved weeds, as well as Japanese grasshopper, Japanese grasshopper, Japanese cyperus, Japanese grasshopper, Japanese grasshopper, Japanese parsley, Japanese parsley, and other annual and perennial weeds that occur in rice fields, from pre-emergence to the 3- to 4-leaf stage. Control is possible. Furthermore, the herbicidal composition of the present invention is highly safe for crops such as paddy rice, and is a herbicidal composition that meets the needs of early- to mid-season treatment agents, which have been particularly required in recent years.
