When long-term storage of an aqueous suspending hazardous biological control composition containing as an active ingredient a pesticide having a high water solubility, in particular, a pesticide having a water solubility of more than 500 mg / L at 20 ° C., the active ingredient particles are grown and stored during storage. There existed a problem that a stable composition was not obtained by dialogue. In order to solve this problem, the present invention (a) pesticides or salts thereof having a water solubility of 500 mg / L to 6,000 mg / L at 20 ℃, (b) polycarboxylate-type surfactant, (c) sulfonic acid Provided are an aqueous suspension harmful control composition comprising a salt surfactant and (d) water. |
