Macrostructure forming surfactants useful as spray drift control agents in pesticide spraying applications

摘要

The disclosure relates to an aqueous agrochemical spray solution comprising at least one agrochemical active and at least one surfactant, wherein said spray solution comprises a dispersed phase comprising dispersed particles which have an average particle size between 1 to 100 microns, wherein the concentration of said dispersed particles is from 0.001 to 5 wt%, and wherein said nitrogen containing surfactant comprises a compound selected from the group defined in the specification, and wherein said aqueous agrochemical spray solution is capable of reducing the volume of the fine droplets in mist whose size is less than 150 microns during spraying by at least 20% compared to the same aqueous spray solution without the presence of the said surfactant. The disclosure also relates to a method of reducing spray drift using said solution.
