TW482654B - Herbicidal composition for paddy fields - Google Patents

Abstract

A herbicide for paddy fields which is highly safe for paddy plants and highly effective against a wide variety of annual and perennial weeds in paddy fields and has a high herbicidal effect also on weeds having resistance to sulfonylurea herbicides. The herbicidal composition is characterized by comprising as the active ingredients 2-[4-(2,4-dichloro-m-toluoyl)-1,3-dimethyl-1H-pyrazol-5-yloxy]-4'-methylacetophenone (common name: benzofenap) and one or more compounds selected from the group consisting of bensulfuron-methyl, azimsulfuron, pyrazosulfuron-ethyl, and imazosulfuron.

Description

W654 A7 printed by Huanggong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs -------- B7 V. Description of the invention (1) [0001] [Technical scope of the invention] The present invention relates to herbicidal compositions, more specifically It is related to the paddy field weeding, which shows extremely high and comprehensive properties to rice before, during or after transplantation to rice, and shows a high weeding effect on a wide range of annual and perennial paddy weeds.剂 组合 物。 Composition. [0002] Conventional techniques So far, more than 4 herbicides have been practically used as paddy fields, and they are generally widely used as a single agent or a mixture containing two or more active ingredients. However, these agents are generally insufficient for perennial weeds for those who are effective for annual weeds. In addition, those who are more effective against perennial weeds, on the contrary, have insufficient effects on annual weeds, and the occurrence of resistant weeds and their phytotoxicity to rice is often a problem. In order to expand the scope of weeding and strengthen the herbicidal effects, we will mix two or more herbicides with different effects, but generally only increase the effect by adding the additive, and it is accompanied by The enhancement of political fruit has a tendency to promote the phytotoxicity of rice. [Problems to be Solved by the Invention] It is safe for water urn, and for paddy field weeds, it has a high effect on a wide range of weed species ranging from annual weeds to perennial weeds, and it is also used as a herbicide for continued hydrazone The development of highly effective herbicides that are resistant to weeds is also desired. [Means for determining issues] The present inventors and other developers who can be developed to meet the above-mentioned expectations of agricultural practitioners (please read the legal and legal matters on the back before filling this page), install _, 11 482654 A7 B7 V. Description of the invention (2 kinds of paddy field herbicides are reviewed. As a result, by combining several compounds with different herbicidal mechanisms and weed control ranges, preferably in a specific ratio, it is possible to selectively prevent miscellaneous impurities in a wide range of paddy fields. Grass, and their herbicidal efficacy ratio is multiplied and the herbicidal scope is expanded when they are used alone. However, contrary to prediction, the phytotoxicity of rice is compared with the case of using the above compounds alone. Lightening, so that the herbicide of the present invention is completed.
