Abstract

PROBLEM TO BE SOLVED: To obtain the subject composition having excellent long-term storage stability and resistant to the decomposition of the herbicidal component by emulsifying a part of three kinds of herbicidal components having different activities, atomizing the remaining part of the components and mixing in water in suspended state. SOLUTION: A flowable agent is prepared by atomizing 2-chloro-N-(3- methoxy-2-thenyl)-2',6'-dimethylacetanilide and methyl α-(4,6- dimethoxypyrimidin-2-ylcarbamoylsulfamoyl)-o-toluate and suspending the compounds in water using a suspension surfactant. Separately, an EW agent is prepared by dissolving n-butyl-(R)-2-[4-(2-fluoro-4-cyanophenoxy) phenoxy]propionate in an organic solvent and emulsifying in water by using a surfactant for emulsification and both agents are mixed with each other to obtain the objective composition. Herbicidal effect can be attained by simply applying the composition to a paddy field after rice transplantation during the period before the generation of weeds to a relatively grown stage of the weeds.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aqueous emulsion suspension comprising a specific active ingredient which can be easily applied to a paddy field after planting, before the emergence of weeds, to the time when the growth of weeds is relatively advanced. Type paddy field herbicide.

[0002]

2. Description of the Related Art Most of the current herbicides for paddy fields are a mixture of selected herbicidal active ingredients, each of which has its own characteristics, so that it can exert a long-term herbicidal effect on a wide range of grass species. Is. Furthermore, all herbicides are formulated in a dosage form that is easy for a sprayer to handle by adding an auxiliary agent to the herbicidal active ingredient.

Conventionally, most of herbicides for paddy fields are granules in which a surfactant is added to a clay component and the herbicidal active component is kneaded. However, in recent years, with the aim of further facilitating the spraying work, a flowable agent in which finely divided herbicidal active ingredients using water as a dispersion medium are suspended by a surfactant, or herbicides dissolved in an organic solvent with water as a dispersion medium. An aqueous herbicide represented by an EW agent (emulsion oil in water) in which an active ingredient is emulsified with a surfactant has been developed and is rapidly spreading.

However, many herbicidal active ingredients have the property that it is difficult to formulate them into these dosage forms. For example, a flowable agent containing a herbicidal active ingredient having a low melting point of 50 ° C. or lower may cause precipitation of crystals of the ingredient when stored for a long period of time. Further, it is difficult to make an herbicidal active ingredient insoluble in an organic solvent into an EW agent. Therefore, the dosage form of the mixed agent containing a plurality of herbicidal active ingredients having the above properties is limited to some dosage forms such as conventional granules.

Among the herbicidal active ingredients in the present invention, 2-
Chloro-N- (3-methoxy-2-thenyl) -2 ′,
6'-Dimethylacetanilide (JP-A-60-0041)
No. 81) has an effect on Nobie from pre-emergence to 2 leaf stage, and n-butyl- (R) 2- [4- (2-fluoro-
4-Cyanophenoxy) phenoxy] propionate (described in JP-A-64-66156) has an effect on the advanced Novier, and methyl = α- (4,6-dimethoxypyrimidin-2-ylcarbamoylsulfamoyl). ) -O-toluate (described in Japanese Patent Application Laid-Open No. 57-112379) is effective for annual weeds and perennial weeds other than Nobie. Can be a herbicide that is effective against

[0006]

However, among these three herbicidal active ingredients, methyl = α- (4,6-dimethoxypyrimidin-2-ylcarbamoylsulfamoyl) -o-toluate is soluble in organic solvents. Is low, it is difficult to form an EW agent, and n-butyl- (R) 2
Since-[4- (2-fluoro-4-cyanophenoxy) phenoxy] propionate has a melting point of 50 ° C or lower, it is difficult to use it as a flowable agent.

We have found that 2-chloro-N- (3-methoxy-2-enyl) -2 ', 6'-dimethylacetanilide, methyl = α- (4,6-dimethoxypyrimidin-2-ylcarbamoyl. Sulfamoyl) -o-toluate and n-butyl- (R) 2- [4- (2-fluoro-4-cyanophenoxy) phenoxy] propionate, which simultaneously contain three herbicidal active ingredients and have a long duration. We have conducted intensive studies to develop a stable aqueous herbicide that does not cause precipitation of crystals and decomposition of herbicidal active ingredients even after storage for a certain period of time.

[0008]

As a result, a part of the above three components is dissolved in an organic solvent and emulsified in water with a surfactant for emulsification, and the rest is finely divided into particles by a surfactant for suspension. By mixing the two into a flowable agent suspended in water, it was found that a stable aqueous emulsion suspension type herbicide which does not cause precipitation of crystals and decomposition of herbicidal active ingredient even after long-term storage is obtained. The present invention has been completed.

That is, the present invention provides 2-chloro-N- (3-methoxy-2-enyl) -2 ', 6'-dimethylacetanilide, methyl = α- (4,6-dimethoxypyrimidin-2-ylcarbamoylsulfate.
