Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an aqueous suspension pesticide formulation and a suspension stabilizer, and more particularly, to an aqueous suspension pesticide formulation which does not separate and settle during long-term storage, and a suspension stabilization therefor. Agent.

2. Description of the Related Art Conventionally, emulsions and wettable powders have been used as pesticide preparations containing high concentrations, but recently, due to problems of safety such as flammability, smell and dusting, and environmental hygiene. The use of a suspending agent (also referred to as a flowable agent) in which water is used as a solvent and a pesticidal active ingredient is dispersed therein has been significantly increased. This suspension has advantages in terms of safety and environmental hygiene compared with emulsions, but on the other hand, dispersoids such as agrochemical active ingredients dispersed in water during sedimentation of the formulation for a long time tend to settle and separate. There are also disadvantages such as the case where the sedimentation layer solidifies and re-dispersion becomes difficult. Conventionally, in order to obtain a stable dispersion for eliminating the sedimentation and separation, various studies have been made on the types of auxiliary agents such as surfactants, thickeners, and organic solvents, and the amounts thereof, and the like.

One of the techniques related to the present invention is

[0005]

As described above, an aqueous suspension using water as a dispersion medium has points to be improved such as long-term storage stability. However, various improved technologies have been proposed, but they are still not enough. Accordingly, an object of the present invention is to provide an aqueous suspension preparation having long-term storage stability and high redispersibility.

[0006]
