Problems solved by technology

This makes it difficult to prepare herbicide compositions that include both glyphosate salts and saflufenacil in a single package
In addition, from the perspective of biology and drug efficacy, the herbicidal effect (especially quick-acting property) of this herbicide composition is insufficient, and it is difficult to be used for commercialization.

[0052] Preparation of Herbicide Compositions

[0053] First, the proportioning shown in the following table 1 and table 2, mixed herbicide active ingredient saflufenacil and wetting agent, dispersant, defoamer, solid micropowder tackifier and water (used 5% of the total consumption of water) ~15%), through wet pulverization (ball mill, KDL-A Type), so that the average particle size of saflufenacil is 1.5 ~ 3 μm. In the next step, after mixing an organic polymer thickener, preservative, and water (using 5 to 15% of the total amount of water used), an organic thickener was prepared using a homogenizer (Homogenizer: IKA / T-25basic) . Add the herbicide active ingredient glyphosate salt, synergist, defoamer, antifreeze and the organic viscosifier to the wet pulverized product, and add the remaining amount of water again to adjust the composition to 100% by weight. Thorough mixing was performed to prepare a herbicide composition in the form of a pre-mixed one pack formulation conta...

Abstract

The present invention relates to a stable aqueous suspension herbicide composition containing glyphosate, and a preparation method thereof. The herbicide composition of the present invention comprises: a glyphosate salt and saflufenacil as herbicidal active ingredients; and one or more types of surfactants selected from the group consisting of (a) a polyoxyalkylene alkyl ether, (b) polyoxyethylene sorbitan fatty acid ester, and (c) a polyoxyalkylene alkyl amine, an alkyl polyglycoside, and a tetraalkyl ammonium organic or inorganic salt, as an effect enhancer.

Description

technical field [0001] The present invention relates to a stable aqueous suspension herbicide composition containing glyphosate, in particular to a physical herbicide prepared by mixing glyphosate-containing salt and saflufenacil as the active ingredient of the herbicide with a synergist Agricultural herbicide compositions in the form of chemically stable aqueous suspensions. Background technique [0002] Among the active ingredients of agricultural herbicides, glyphosate salt and saflufenacil have herbicidal effects on broadleaf and gramineous weeds. In particular, glyphosate salt is a widely used herbicide because of its relatively low price. However, its herbicide effect is slow and it is difficult to use it as an efficient herbicide. In order to solve this problem, there have been attempts to effectively control weeds by mixing the active ingredients of herbicide saflufenacil and glyphosate salt (for example, refer to WO2009 / 156322). [0003] However, the disclosed tec...
