The invention provides a pymetrozine-containing ultralow volume liquid agent, and belongs to the field of pesticides. The ultralow volume liquid agent consists of pymetrozine or active ingredient compounded by using the pymetrozine and an active ingredient II, and the balance of aids and solvent; and the active ingredient II is any one of bifenthrin, beta-cypermethrin, lambda-cyhalothrin, cyfluthrin, fenpropathrin, deltamethrin, etofenprox, triazamate, tolfenpyrad, chlorantraniliprole, flubendiamide, ethiprole, abamectin, emamectin benzoate, ivermectin, sec-butyl phenyl-N-methyl carbamate, buprofezin, hexaflumuron, flufenoxuron, chlorbenzuron, diafenthiuron, indoxacarb, 1,2-Dibenzoyl-1-tert-butylhydrazine and tebufenozide. The ultralow volume liquid agent is used for preventing and controlling multiple pests on paddy, wheat, corn, vegetables, tobacco, tea trees, fruit trees and sugarcane by ultralow volume spraying, low volume spraying or ultralow volume electrostatic spraying. The ultralow volume liquid agent has the advantages of low water consumption, high effect, long acting time, synergy and the like.
