Abstract:
An aqueous spray composition having a plurality of spray droplets with a median diameter, for applying about 0.001 to 50 wt/wt % of a pesticide, the improvement comprising about 0.001 to 1 wt/wt % of a water-soluble poly(ethylene oxide) having a molecular weight greater than about 5.times.10.sup.5 Daltons, and at least about 0.05 wt/wt % of a surfactant selected from the group consisting of a sulfonated surfactant, a sulfated surfactant and mixtures thereof, provided that the surfactant has at least one straight or branched carbon chain containing at least nine carbon atoms, wherein, for a given spray apparatus, application, and conditions, and based on the water-soluble polymer and surfactant, the median diameter of the plurality of spray droplets is increased above that of an aqueous spray composition without said water-soluble polymer and surfactant.
