The invention provides an ultra-low volume liquid containing flutolanil which is compounded by flutolanil or flutolanil and an active ingredient II into an active ingredient, and others components are assistants and solvents; and the active ingredient II is any one of metalaxyl, dimethomorph, tricyclazole, propiconazole, difenoconazole, isoprothiolane, iprobenfos, kasugamycin, polyoxin, validamycin, tebuconazole, hexaconazole, diniconazole, triadimefon, epoxiconazole, flusilazole, azoxystrobin, kresoxim-methyl, trifloxystrobin, enestroburin or pyraclostrobin. The ultra-low volume liquid has the advantages of convenience in processing, long duration, high work efficiency, low possibility of generating resistance to pesticides by a target, low environmental contamination, economy of drug and water, and improvement in pesticide utilization rate; and through ultra-low volume spraying, low volume spraying or ultra-low volume static spraying, various pests of rice, wheat, corn, vegetables, tobacco, tea trees, fruit trees and sugarcanes can be prevented and treated.
