A composition comprising at least one monosaccharide selected from D-tagatose, D-allose, D-psicose, D-talose, D-sorbose, D-galactose, Lfructose, D-mannose and D-mannitol as an active ingredient and multiple surfactants selected from an anionic surfactant selected from aryl sulfonates, formalin condensates of aryl sulfonates, alpha-olefin sulfonates, alkyl sulfonates, alkyl diphenyl ether disulfonates, polyoxyethylene alkyl phenyl ether sulfonates, polyoxyethylene alkyl ether sulfosuccinic acid half esters, alkyl sulfates, sulfosuccinates, polyoxyalkylene aryl ether sulfates, polyoxyalkylene alkyl ether sulfates, polyoxyethylene-polyoxypropylene block polymer sulfates, polyoxyalkylene alkyl ether acetates, polyoxyalkylene aryl ether phosphates, polyoxyalkylene alkyl ether phosphates, polyoxyethylene-polyoxypropylene block polymer phosphates, alkyl phosphate esters, methyl taurates, polycarboxylates and fatty acid salts, wherein the anionic surfactants are at a blending ratio of 0.001 to 40 parts by weight based on 1 part by weight of monosaccharide, and is effective as an agricultural control composition against plant disease, particularly plant disease caused by fungi and plant disease caused by bacteria.
