Provided herein is a liquid pesticidal composition which includes an emulsifier component present in an amount from 3 to 35 parts by weight per 100 parts by weight of the liquid pesticidal composition, a pesticide present in an amount from 1 to 90 parts by weight per 100 parts by weight of the composition, and an optional solvent present in an amount from 0 to 90 parts by weight per 100 parts by weight of the composition. The emulsifier component includes an alkaline earth salt of, or amine salt of, a C-Cfatty acid along with an alkyl polyglycoside present in an amount from 1 to 20 parts by weight per 100 parts by weight of the composition. The emulsifier component may also include an optional co-emulsifier present in an amount from 0 to 20 parts by weight per 100 parts by weight of the composition.
