ぐに固結して水希釈性の劣る原因となる。By the way, in order to develop a practical product, it is necessary to prepare a solid formulation such as a powder for use by diluting with water, instead of a spray liquid of such a pest controlling agent. It is necessary to consider a form suitable for distribution. However, a powdery preparation containing a water-soluble polymer does not have sufficient long-term storage stability and immediately solidifies, causing poor water dilutability.
