Abstract
The present invention provides a low-irritant pesticidal emulsifiable concentrate comprising (a) 1 to 60% by weight of at least one pesticidal active ingredient compound selected from the group consisting of pyriproxyfen and a pyrethroid compound, (b) 2 to 15% by weight of at least one surfactant and (c) 15 to 90% by weight of at least one aromatic ester solvent represented by the formula: Ar—X—COOR [1] or the formula: RCOO—X—Ar [2] [wherein R represents non-aromatic group having 1 to 6 carbon atoms; Ar represents an aromatic group; and X represents a single bond or an alkylene group having 1 to 6 carbon atoms]. The pesticidal emulsifiable concentrate of the present invention can be used as an emulsion which is superior in emulsion stability when using after diluting with water, and has low irritation.
