There was a problem in that if an aqueous pesticide suspension containing an agricultural chemical having a high solubility in water as an active ingredient, especially an agricultural chemical having a solubility in water in excess of 500 mg / L at 20 ° C, is stored for a long time period of time, then the particles of the active ingredient tend to grow and become coarse-grained, thereby achieving a stable suspension is difficult. To solve such a problem, the present invention provides an aqueous pesticidal suspension comprising: (a) an agricultural chemical or its salt having a solubility in water of 500 to 6000 mg / L at 20 ° C, b) a polycarboxylate type surfactant, c) sulfonate type surfactant; and d) water. |
