An agrichemical-containing composition that exhibits excellent agrichemical efficacy is provided. The agrichemical-containing composition comprises hydroxypropyl cellulose, an agrichemical, an organic solvent having a saturated vapor pressure of 50 mmHg or higher at 25°C, and water. When the composition as a whole is taken as 100 wt%, the content of the organic solvent is 0.02 to 1 wt%, and the weight ratio of the hydroxypropyl cellulose to the organic solvent (hydroxypropyl cellulose / organic solvent) is in a range of 0.1 to 2.
