Estimating the term…
The present invention relates to an aqueous agrochemical spray solution containing an agrochemical active and a surfactant. The spray solution comprises a dispersed phase comprising dispersed particles which have an average particle size between 1 to 100 microns and the concentration of said dispersed particles is from about 0.001 to 5 wt %. The 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 surfactant. The present invention also relates to a method of reducing the spray drift of an aqueous agrochemical spray solution upon spraying with a spraying apparatus. The method includes adding the surfactant to the aqueous agrochemical spray solution in an amount effective to form the dispersed phase.
An aqueous agrochemical spray solution comprising at least one agrochemical active and at least one surfactant, wherein said at least one surfactant comprises an alkoxylated amide, 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 about 0.001 to 5 wt %, 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, and wherein said aqueous agrochemical spray solution does not comprise either (a) a tertiary amine surfactant of the formula:
An agrochemical formulation comprising an active ingredient and at least one surfactant, wherein said at least one surfactant comprises an alkoxylated amide, wherein the said agrochemical formulation is capable of forming a aqueous agrochemical spray solution containing 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 about 0.001 to 5 wt %, wherein said aqueous 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, and wherein said aqueous agrochemical spray solution does not comprise either (a) a tertiary amine surfactant of the formula:
A method of reducing the spray drift of an aqueous agrochemical spray solution upon spraying with a spraying apparatus, which comprises adding at least one surfactant to said aqueous agrochemical spray solution in an amount effective to form a dispersed phase comprising dispersed particles which have an average particle size between 1 to 100 microns, wherein said at least one surfactant comprises an alkoxylated amide, wherein the concentration of said dispersed particles is from about 0.001 to 5 wt %, wherein said aqueous 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, and wherein said aqueous agrochemical spray solution does not comprise either (a) a tertiary amine surfactant of the formula:
