1. An efficacy-enhancing agent composition for agricultural chemicals, comprising (A) a sorbitan fatty acid ester surfactant, (B) a rosin-oxyalkylene adduct surfactant or a quaternary ammonium salt surfactant represented by the formula (B1), and (C) a glycol ether solvent represented by the formula (C1), wherein the content of (A) is 20 to 60% by weight, the content of (B) is 0.2 to 6% by weight and the content of (C) is 30 to 70% by weight: wherein at least one of R1, R2 and R3 is a linear or branched alkyl or alkenyl group, having 8 to 30 carbon atoms, the other is one of —CH3, —CH2CH3, wherein n=1 to 5, or combination thereof; R4 represents —CH3 or —CH2CH3; and a counter ion X− represents one, two or more anionic groups derived from an anionic oligomer or polymer, having an average molecular weight of 300 to 20000, selected from the group consisting of the followings 1) to 3), 1) polymers comprising one, two or more units derived from an essential construction monomer selected from the group consisting of unsaturated carboxylic acids and derivatives thereof, 2) polymers comprising styrenesulfonic acid as an essential construction monomer, and 3) formalin condensates of sulfonated polycyclic aromatic compounds that may be substituted with a hydrocarbon group,
R5—O—(CH2CH2O)n—H  (C1) wherein, R5 represents a linear or branched alkyl group having 1 to 6 carbon atoms or a linear or branched alkenyl group having 2 to 6 carbon atoms; and n represents 2 or 3, and wherein a weight ratio of the component (C) to components (A) and (B), (C)/[(A)+(B)], is 0.6 to 1.2.
