Claim:
1. A pesticidal composition in the form of an aqueous emulsion, comprising: (a) 2.5 to 15% by weight of a pesticidally active ingredient in which a retention rate is less than 50% after irradiation with xenon light (290 nm cutoff) at an intensity of 0.68 W/m (b) 10 to 25% by weight of a hydrophobic organic solvent selected from the group consisting of esters, ketones, aromatic hydrocarbons, and paraffins, wherein the esters are selected from the group consisting of diisobutyl adipate, diisodecyl adipate, octyl oleate, lauryl oleate, and octyldodecyl oleate; (c) 1 to 5% by weight of a water-soluble polymer dispersing agent; and (d) water; wherein liquid droplets in which the pesticidally active ingredient is suspended or dissolved in the hydrophobic organic solvent are emulsified in an aqueous continuous phase, a weight ratio of the pesticidally active ingredient to the hydrophobic organic solvent is from 17:83 to 70:30, the liquid droplets have an average particle diameter of 14.9 to 60 μm, and the water-soluble polymer dispersing agent is dissolved in water.
