The invention relates to an ultra-low-volume liquid containing lufenuron and carbamate pesticide. Lufenuron and an active ingredient II are compounded to form a chemical component of the ultra-low-volume liquid, and remaining components of the ultra-low-volume liquid include a surfactant and a solvent. The active ingredient II is optionally one of carbosulfan, benfuracarb, nitrilacarb, fenobucarb, isoprocarb, triazamate, pirimicarb, metolcarb, dimethacarb, carbaryl, methiocarb, methomyl or thiodicarb. The ultra-low-volume liquid is convenient to process, long in lasting effect and high in work efficiency, targets cannot generate pesticide resistance easily, the environmental pollution is low, the pesticide and water are saved, the pesticide utilizing rate is improved, and various pests of rice, wheat, corns, vegetables, tobaccos, tea trees, fruit trees and sugarcane can be controlled by ultra-low-volume spraying, low-volume spraying or ultra-low-volume electrostatic spraying.
