Description

The present invention relates to liquid agrochemical compositions.

Among agrochemical formulations, formulations containing water have less impact on the environment than non-aqueous liquid formulations, and are safe for users as they are not flammable. Generally, as a method for manufacturing liquid preparations containing water, a method is known in which a pesticide component is finely pulverized to form a suspension preparation. However, it is difficult to make a suspension formulation for pesticide ingredients whose solubility in water exceeds a certain level, and in such cases, a liquid component with high solubility of the pesticide ingredient is added to water, and the active ingredient is dissolved in the liquid component. It is necessary to make it into a liquid formulation. For example, Patent Document 1 discloses a liquid formulation containing a pesticide component and a mixed solvent of a solvent and water, and the solubility of the pesticide component in the mixed solvent is higher than the solubility of the pesticide component in the solvent or water. It has been shown that

International Publication No. 2018/79565

However, even when the technique described in Patent Document 1 is used, crystals of the agricultural chemical active ingredient may precipitate during storage.
Therefore, an object of the present invention is to provide a liquid agrochemical composition with excellent storage stability, in which crystal precipitation of the agrochemical active ingredient is suppressed during storage.

In order to solve the above problems, the inventor conducted intensive studies and found that when a solvent with a specific chemical structure is combined with a glycol ether solvent, crystal precipitation of the active ingredient of the pesticide is suppressed and the storage stability is excellent. I found out.
That is, the present invention is as follows.
