Abstract
A water-based pesticidal composition contains 100 weight parts of substantially water-insoluble pesticide and 1.7-200 weight parts of a surface active agent. The surface active agent contains Component A and Component B at weight ratio of A/B=80/20-20/80. Component A is polyalkylene glycol ether derivative of polyethylene polyamine shown by the following general formula and having molecular weight of 20,000-100,000: ##STR1## where R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are selected from the group consisting of hydrogen, alkyl group with 1-4 carbon atoms, alkanoyl group with 2-18 carbon atoms, alkenoyl group with 2-18 carbon atoms and polyoxyalkylene glycol group containing oxyethyne unit and oxypropylene unit at weight ratio of (oxyethyne unit/oxypropylene unit=)100/0-50/50, at least one of R.sup.1, R.sup.2, R.sup.3 and R.sup.4 being the polyoxyalkylene glycol group, and n is an integer 2-250. Component B includes one or more selected from the group consisting of partial esters of polyhydric alcohol selected from sorbitol, sorbitan, glycerine and polyglycerine and unsaturated aliphatic acid with 16-22 carbon atoms and ethylene oxide adducts of such partial esters.
