Embodiment 1

[0069] 1. Preparation of pulverized slurry

[0070] Disperse 0.2 parts of bentonite [trade name: VEEGUM R, manufactured by R.T. VANDERBILT] in 41.26 parts of water, 2 parts of polyoxyethylene tridecyl ether [trade name: SYNPERONIC 13 / 12-LQ, manufactured by Croda], acrylic A mixture of copolymer and propylene glycol [trade name: ATLOX 4913-LQ, manufactured by Croda] 3 parts, propylene glycol 6 parts, and a silicone-based antifoaming agent [trade name: DOW CORNING ANTIFOAM C EMULSION, manufactured by DOW CORNING] 0.5 parts, Disperse 22.04 parts of thiafluzamide technical substance (active ingredient concentration: 96.18%) therein, use 0.8-1.2 mmφ glass beads, carry out wet pulverization with a sand mill [Aimex Co., Ltd.] to obtain 75 parts of pulverized slurry.

[0071] 2. Modulation of dispersion medium

[0072] Disperse 0.4 parts of xanthan gum [trade name: RHODOPOL 23, manufactured by Rhodia] and 0.04 parts of 1,2-benzisothiazolin-3-one [trade name: PROXEL GXL, manufactured ...

Embodiment 2

[0076] The same method as in Example 1 was adopted except that 41.26 parts of water in the pulverized slurry in Example 1 was changed to 41.16 parts, and 0.2 parts of bentonite [trade name: VEEGUM R, manufactured by R.T. VANDERBILT] was changed to 0.3 parts. Manufactured to obtain an aqueous suspension pesticide composition.

Embodiment 3

[0078] 1. Preparation of pulverized slurry

[0079] Disperse 2 parts of polyoxyethylene tridecyl ether [trade name: SYNPERONIC 13 / 12-LQ, manufactured by Croda], a mixture of acrylic copolymer and propylene glycol in 41.46 parts of water [trade name: ATLOX 4913-LQ, manufactured by Croda] 3 parts of propylene glycol, 6 parts of propylene glycol, and 0.5 parts of a silicone-based antifoaming agent [trade name: DOW CORNING ANTIFOAM C EMULSION, manufactured by DOW CORNING], dispersing 22.04 parts of thiafluzamide in it, using 0.8-1.2mmφ The glass beads were wet pulverized with a sand mill [made by Aimex Co., Ltd.], and 75 parts of pulverized slurries were obtained.

Abstract

The invention provides a novel aqueous suspending pesticide composition. The manner to solve the issue of the invention is to provide the aqueous suspending pesticide composition. The composition comprises (1) thifluzamide, (2) an organic thickening agent and (3) an inorganic thickening agent, wherein the (2) organic thickening agent is heteropolysaccharide preferably, and is xanthan gum more preferably, and the (3) inorganic thickening agent is smectite clay mineral preferably and is bentonite more preferably.

Description

Technical field [0001] The present invention relates to an aqueous suspension pesticide composition excellent in storage stability. Background technique [0002] Thiflufenac (common name) is a well-known compound having bactericidal activity (see, for example, Patent Document 1). [0003] In an aqueous suspended pesticide composition in which a poorly water-soluble pesticide active ingredient is dispersed in water, it is difficult to ensure the uniformity of the composition under high temperature conditions, and separation of the supernatant liquid and hard agglomeration may occur. If the composition becomes uneven during storage, the prescribed amount of medicine cannot be spread, and there is a risk that it may cause insufficient efficacy or damage to the medicine. As an example of an aqueous suspension pesticide composition with excellent storage stability, an aqueous suspension pesticide composition containing a pesticide active ingredient, bentonite, and heteropolysacc...
